Description

200907491 IX. Description of the Invention [Technical Field] The present invention relates to an antireflection film, a polarizing plate using the same, and an image display device. [Prior Art] A general anti-reflection film is an image display device such as a cathode tube display device (CRT), a plasma display (PDP), an electroluminescence display (ELD), or a liquid crystal display device (LCD). The contrast reduction caused by light reflection or the like of the image is absorbed by the light of the multilayer film, and has the function of reducing the reflectance, and is disposed on the outermost surface of the display. The general reflection prevention is carried out under a low refractive index layer which is formed on the transparent film substrate directly or via another layer and has a refractive index lower than that of the underlayer. Further, when the surface of the optical article is damaged, the visibility of the display panel is deteriorated, so that the antireflection film imparts hardening properties. In addition, since the optical article made of plastic is insulative, it is charged by static electricity or the like, and the visibility of the display panel caused by adhesion of dust on the surface is prevented from being deteriorated, and it is expected to impart antistatic performance. Patent Document 2 discloses that as a method for imparting these curing properties and antistatic properties, a hard coat layer is formed on a transparent film substrate, an antistatic layer containing a metal oxide is formed thereon, and a refraction of the underlayer is further formed thereon. A method of manufacturing an antireflection film by using a low refractive index layer having a low rate. Further, in recent years, the use environment of the antireflection film has various forms such as outdoor or chamber -4-200907491. In particular, it is required to use an optical film excellent in flatness or hardness or scratch resistance and excellent in environmental change under large-screen use for outdoor use. In the past, in particular, those having excellent wide-width and low-film properties have not been able to obtain durability against scratch resistance or environmental change (specifically, chemical resistance under high temperature and high humidity). Patent Document 3 discloses that water vapor permeation in the antireflection film is suppressed in a high-humidity environment, and deterioration of the antireflection film such as dimensional change of the substrate is prevented, and water is used as a water between the hard coat layer and the low refractive index layer. Vapor Interruptive Metal Oxide Layer The antimony oxide layer is provided with an antireflection film by vacuum evaporation. Further, a hard coating layer is formed on the transparent film substrate, and the high refractive index layer and the low refractive index layer are formed in the antireflection film of the laminated structure in the order of the high refractive index layer and the low refractive index layer. When the refractive index difference is too large, the reflection spectrum will be in a V shape, and the reflectance in the short-wavelength region or the long-wavelength region in the visible light region will be too high, so that the color of the antireflection film is generated. Patent Document 4 discloses a method of forming an antistatic layer made of a conductive metal oxide, a refractive index-reducing material, and an ionizing radiation-curable resin for the purpose of suppressing the coloration of the antireflection film. [Patent Document 1] JP-A-2006-35624 (Patent Document 3) JP-A-2006-35624 (Patent Document 4) JP-A-2005-292510 Disclosure of the Invention Problems to be Solved by the Invention-5-200907491 However, in Patent Document 1, a hard coating layer is used as a hard coating layer, an antistatic layer, and a low refractive index layer on one surface of a transparent plastic film. In the antireflection film formed by sequentially laminating the transparent plastic film side, the refractive index of the antistatic layer is 1.60 to 1.7, and the reflectance of the low refractive index layer is 1.40 or less. Further, Patent Document 2 discloses that a high refractive index layer having ultraviolet curability and metal oxide particles is provided on at least one surface of a transparent substrate, and a low refractive index layer having thermosetting property is provided on the layer. The refractive index of the high refractive index layer is set to 1.5 to 2.5, and the reflectance of the low refractive index layer is set to be in the range of 1.2 5 to 1.4 5 . Thus, the antistatic layer containing a metal oxide as an antistatic agent generally has a high refractive index and is laminated on the transparent substrate in the order of a hard coating layer, an antistatic layer, and a low refractive index layer. The difference in refractive index between the layer and the low refractive index layer causes the reflectance waveform to be V-shaped, and the short-wavelength in the visible light region and the reflectance in the long-wavelength region become high. Blue and red appear strongly as reflected colors. When the reflection color in the visible light region is more pronounced in blue or red, the unevenness of the reflection color is more remarkable due to the uneven thickness of the coating film during production, which impairs the consumer's quick identification, so as a patent. There is a lack of practicality in the antireflection films of Documents 1 and 2. In order to obtain a fast recognizability as a state of a color tone having no reflection color in the visible light region, it is a so-called natural color, and it is difficult to make the film thickness unevenness at the time of production difficult. In order to control the reflected color in the visible light region to be a natural color, there is a means for reducing the amount of metal oxide particles contained in the antistatic layer and reducing the refractive index of the low antistatic layer of -6 - 200907491, but the metal oxide particles The problem of deteriorating the antistatic property of the film itself is reduced, and it is excellent in both natural color and antistatic property. Further, in the vacuum vapor deposition method required for the production of the antireflection film described in Patent Document 3, a bulky vacuum vapor deposition device is indispensable, and in recent years, it has been impossible to mass-produce an antireflection film having a wide width at a time. The problem is, by cost, the production efficiency is not sufficient. Further, in the antireflection film described in Patent Document 3, the use of an acrylic resin as an organic binder in the hard coat layer has the interlayer adhesion between the hard coat layer and the water vapor barrier ruthenium oxide layer. A full problem. Further, in the method for producing an antireflection film described in Patent Document 4, the adhesion between the antistatic layer and the low refractive index layer is not sufficient, so that the durability against environmental changes is deteriorated. The object of the present invention is to solve the above problems of the prior art, and to provide an excellent adhesion between layers, hardness, rub resistance, antistatic property, and uneven coating unevenness during production, and resistance to high temperature and high humidity.

The hardening step can be described as described in the low refractive index layer described later. Further, when the dry film thickness is to be the above film thickness, the solid content concentration of the coating composition is adjusted. (Low Refractive Index Layer) Next, the low refractive index layer of the antireflection film of the present invention will be described. The low refractive index layer of the antireflection film of the present invention is a layer having a lower refractive index than that of the transparent film substrate, and is referred to as a low refractive index layer. The specific refractive index is preferably in the range of 1.30 to 1.45 at 23 ° C and 550 nm. Further, the film thickness of the low refractive index layer is preferably 5 nm to 0.5 μm, more preferably 10 nm to 0.3 μm, and more preferably 30 nm to 0.2 μm, as the characteristics of the optical interference layer. The low refractive index layer of the antireflection film of the present invention contains hollow particles, and it is preferable that -29-200907491 is a characteristic of an optical interference layer having a low refractive index. Further, the low refractive index layer of the antireflection film of the present invention is preferably one having at least one type of hollow ceria particles containing a porous or void therein. The hollow particles are (1) composite particles formed by a porous particle and a coating layer provided on the surface of the porous particle, or (2) having a cavity therein, and the contents are filled with a solvent, a gas or a porous substance. The hollow particles are 〇 and the 'empty particles are particles with voids inside, and the voids are surrounded by the walls of the particles. The contents of the solvent, gas, or porous substance used in the preparation of the cavity are filled. The hollow fine particles have an average particle diameter of 5 to 200 nm, preferably 10 to 70 nm. The particle size of the hollow particles is preferably a monodisperse having a coefficient of variation of from 1 to 40%. The average particle diameter of the hollow particles used in the present invention can be measured by an electron micrograph by a scanning electron microscope (SEM) or the like. The measurement is carried out by using a particle size distribution meter such as a dynamic astigmatism method or a static astigmatism method. The average particle diameter of the hollow particles used in the present invention can be appropriately selected in accordance with the transparent coating thickness of the formed low refractive index layer, and the film thickness of the transparent envelope is preferably 3/2 to 1/10, preferably 2 /3~1/10. Among them, the hollow particles are preferably dispersed in a suitable medium due to the formation of a low refractive index layer. As the dispersing medium, water, alcohols (for example, methanol, ethanol, isopropanol), and ketones (for example, methyl ethyl ketone, methyl isobutyl ketone), ketone alcohols (for example, diacetone alcohol), and Propyl monomethyl ether, propylene glycol monomethyl ether acetate, and the like are preferred. The thickness of the coating layer of the composite particles or the particle wall thickness of the void particles is -30-200907491 1 to 40 nm, preferably 1 to 2 〇 nm, and more preferably, when the thickness of the coating layer is less than 1 nm, coating may be performed. When the liquid component is less likely to enter the inside of the composite particle, the effect of the low refractive index is not obtained. When the thickness exceeds 2 〇 nm, the coating liquid component does not decrease in porosity (pore volume), and the effect may not be obtained. Further, in the case of the void particles, the particle shape cannot be maintained at the time of the particle wall, and even if the thickness exceeds the sufficient effect of lowering the refractive index. It is preferable that the coating of the composite particles or the main component of the void particles is preferable. Further, examples of the oxidation include Al2?3, B2O3, Ti?2, Zr?2, Sb203, Mo03, Zn02, W03 and the like. Examples of the particles include those obtained by cerium oxide, those obtained by inorganic compounds, and CaF2 and NaF. Among them, a porous particle composed of a composite oxide of cerium oxide and a dioxide is preferable as an inorganic compound other than cerium oxide: B 2 〇 3 ' T i 0 2 ' Z r 0 2 ' S η Ο 2 ' One type or two or more types of Ce〇2, Ζ 02 02 02, and W03. Such a ruthenium is represented by SiO 2 , and the molar ratio MOx/SiO in the conversion of ruthenium dioxide is preferably in the range of 0.001 to 0.3. 2 to 15 nm. The composite particles cannot completely coat the particles, and the internal porosity is reduced. Further, when the thickness of the coating layer is inside, and the thickness of the composite particles which is obtained by lowering the refractive index is less than 1 nm, the thickness of the coating layer is not more than 20 nm, and the solid particle wall cannot be made of cerium oxide as a component other than cerium, specifically S η Ο 2 ' Ce〇2, Ρ 2 〇3 ' The porous cerium oxide and the cerium oxide constituting the composite particles, and the inorganic compound cerium other than cerium, such as NaAlF6 or MgF, may be exemplified by A1203, 2〇3, and S b 2 0 3 'M0O3, in the porous particles, the inorganic compound of dioxane is oxidized 2 to 0.0001~1. 〇, compared with -31 - 200907491 It is difficult to obtain the molar ratio of the porous particles MOx/Si〇2 to o.oooi' even if It is also found that the pore volume is also small, and it is impossible to obtain particles having a lower refractive index. Further, when the molar ratio of the porous particles exceeds 1. 〇, the ratio of cerium oxide becomes small, so that the pore volume becomes large, and it is difficult to obtain a refractive index lower. The pore volume of the porous crucible _11 is in the range of 〇 1 to 1.5 m 1 / g, preferably in the range of 0.2 to 1.5 ml/g. When the pore volume is less than im.iml/g, particles having a sufficiently lowered refractive index cannot be obtained. When the pore volume exceeds 1.5 ml/g, the strength of the particles is lowered, and the strength of the obtained coating is lowered. Further, the pore volume of such a porous particle can be obtained by a mercury intrusion method. Further, examples of the content of the void particles include a solvent, a gas, a porous substance, and the like which are used in particle preparation. The solvent may contain void particles, unreacted materials of the particle precursor used for preparation, and a catalyst to be used. Further, examples of the porous material include those exemplified as the porous particles. These contents may be a single component or a mixture of plural components. As a method for producing the hollow particles, for example, a method of preparing composite oxide colloidal particles disclosed in paragraphs [0010] to [33] of JP-A-7-11-3015. When the specific composite particles are made of an inorganic compound other than cerium oxide or cerium oxide, hollow particles can be produced by performing the following first steps to third steps. (1st step: preparation of porous particle precursor) In the first step, the raw material of the raw material of the inorganic compound other than the raw material of the antimony dioxide and the non-oxidized -32-200907491 is prepared in advance, or the ceria is prepared. A mixed aqueous solution of a raw material and an inorganic compound raw material other than cerium oxide, and a composite ratio of the aqueous solution as the intended composite oxide are added to the aqueous alkali solution of pH IO or more, and the porous precursor precursor is gradually added thereto. As the raw material of cerium oxide, an alkali metal, ammonium or organic base phthalate can be used. As the alkali metal citrate, sodium citrate (water glass) or potassium citrate can be used. The organic base may, for example, be a fourth-order ammonium salt such as a tetraethylammonium salt or an amine such as monoethanolamine, diethanolamine or triethanolamine. Further, the ammonium citrate or the organic acid citrate also contains an alkaline solution of ammonia, a fourth-order ammonium hydroxide, an amine compound or the like in the citric acid solution. Further, as a raw material of an inorganic compound other than cerium oxide, an alkali-soluble inorganic compound can be used. Specific examples thereof include an oxidizing acid of an element selected from the group consisting of Al, B, Ti, Zr, Sn, Ce, P, Sb, Mo, Zn, and W, an alkali metal salt of the oxidizing acid, an alkaline earth metal salt, and an ammonium salt. Grade 4 ammonium salt. More preferred are sodium aluminate, sodium tetraborate, ammonium cerium carbonate, potassium citrate, potassium stannate, sodium citrate, sodium molybdate, cerium ammonium nitrate, sodium citrate. Although the pH of the mixed aqueous solution changes with the addition of these aqueous solutions, it is not particularly necessary to control the pH to a predetermined range. The aqueous solution ultimately determines its pH based on the type of inorganic oxide and its mixing ratio. The rate of addition of the aqueous solution at this time is not particularly limited. Further, in the production of composite oxide particles, a dispersion of seed particles can be used as a starting material. The particles are not particularly limited, and inorganic oxides such as si 〇 2, Al 2 〇 3 - 33 to 200907491, TiO 2 or ZrO 2 or particles of the composite oxides thereof can be used, and generally, they can be used. Further, the porous particle precursor dispersion obtained by the above production method can also be used as a seed particle dispersion. When the seed particle dispersion is used, the pH of the seed particle dispersion is adjusted to 1 Torr or more, and then an aqueous solution of the above compound is added to the aqueous alkali solution with stirring in the dispersion of the particles. At this time, it is not necessary to carry out dispersion pH control. When such a seed particle is used, it is easy to control the particle size of the prepared porous particle, and a uniform particle size can be obtained. The above-mentioned ceria raw material and inorganic compound raw material have a high solubility in alkali. However, when the two are mixed in a large pH region of the solubility, the solubility of oxidized acid ions such as citrate ions and aluminate ions is lowered, and these complexes are precipitated to grow into particles or cause growth of particles precipitated on the seed particles. . Therefore, it is not necessary to perform p Η control as in the past method when the particles are precipitated and grown. The composite ratio of the inorganic compound other than the cerium oxide and the cerium oxide in the first step is converted to the oxide ( Μ〇χ ) of the inorganic compound of the cerium oxide, and the molar ratio of MO x / SiO 2 is 0.05 to 2.0. Preferably, it is in the range of 0.2 to 2.0. The smaller the ratio of cerium oxide in this range, the larger the pore volume of the porous particles. However, even if the molar ratio exceeds 2.0, the pore volume of the porous particles hardly increases. On the other hand, when the molar ratio is less than _ 〇 〇 5, the pore volume becomes small. When modulating the void particles, the molar ratio of MOx/Si〇2 is preferably in the range of 0.25 to 2.0. -34-200907491 (Second step: removal of inorganic compound other than cerium oxide from porous particles) In the second step, the porous precursor precursor obtained from the first step is an inorganic compound other than cerium oxide (矽At least a portion of the element other than oxygen is selectively removed. As a specific removal method, the inorganic compound in the porous particle precursor is dissolved or removed by using a mineral acid or an organic acid, or is contacted with a cation exchange resin, and then subjected to ion exchange and removal. Further, the porous particle precursor system obtained in the first step is a mesh structure particle in which an element of an inorganic compound is bonded to oxygen via an inorganic compound. By thus removing the inorganic compound (the element other than cerium and oxygen) from the porous particle precursor, a porous particle having a large pore volume in the porous body can be obtained. Further, by removing the amount of the inorganic oxide (the element other than cerium and oxygen) from the porous particle precursor, the void particles can be prepared. Further, before removing the inorganic compound other than cerium oxide from the porous particle precursor, the fluorine-containing content obtained by subjecting the alkali metal salt containing cerium oxide to alkali removal is added to the porous particle precursor dispersion obtained in the first step. A ruthenium acid solution or an organic hydrazine compound which is a substituted decane compound of an alkyl group, or a hydrolyzate thereof or a polycondensate thereof is preferred to form a cerium oxide protective film. The thickness of the cerium oxide protective film may be 0.5 to 40 nm', preferably 0.5 to 15 nm. Further, even if the protective film of the step is formed, the protective film of the step is porous, and the inorganic compound other than the above-mentioned silica sand can be removed from the porous precursor of the porous particles. By forming such a cerium oxide protective film 'in a particle shape, the above inorganic compound other than cerium oxide can be removed from the porous particle precursor -35-200907491. Further, when the ceria coating layer to be described later is formed, the pores of the porous particles are not clogged by the coating layer, so that the pore volume can be formed without forming a ceria coating layer to be described later. Further, when the amount of the inorganic compound to be removed is small, the particles are not destroyed, and it is not necessary to form a protective film. Further, when the void particles are prepared, it is preferable to form the ceria protective film. When the void particles are prepared, when the inorganic compound is removed, a precursor of the void particles formed by the cerium oxide protective film, the solvent in the cerium oxide protective film, and the undissolved porous solid component can be obtained. When a coating layer to be described later is formed in the body, the formed coating layer becomes a particle wall to form void particles. The amount of the ceria source to be added in order to form the above-mentioned ceria protective film is preferably less in the range in which the particle shape can be maintained. When the amount of the silica sand source is too large, the cerium oxide protective film is too thick, and it is difficult to remove inorganic compounds other than cerium oxide from the porous particle precursor. As the hydrolyzable organic phosphonium compound for forming a ceria protective film or a hydrolyzate thereof or a polycondensate thereof, the alkoxydecane represented by the following general formula (1 1 ) can be used.

RnSi ( OR5 ) 4-n (11) wherein R and R' represent a ketone group such as a yard group, a square group, an ethylene group or a propyl group, and η represents 〇, 1, 2 or 3. In particular, it is preferable to use a fluorine-substituted tetramethoxy fluorene, tetraethoxy silane, tetraisopropoxy sand or the like, and a tetra-oxygen sand courtyard is preferably used as an additive method, and these alkoxylates will be used. A solution of a small amount of a base or an acid as a catalyst added to a mixed solution of a decane, a pure water, and an alcohol, added to a dispersion of porous particles, and a mixture of alkoxy decane, pure water, and an alcohol A solution of a small amount of a base or an acid as a catalyst is added to the solution, and is added to the dispersion of the porous particles, and the decanoic acid polymer obtained by hydrolyzing the alkoxydecane is attached to the surface of the inorganic oxide particles. In this case, alkoxydecane, an alcohol, and a catalyst may be simultaneously added to the dispersion. As the base catalyst, ammonia, an alkali metal hydroxide or an amine can be used. Further, as the acid catalyst, various inorganic acids and organic acids can be used. When the dispersion medium of the porous particle precursor is water alone or when the ratio of water to the organic solvent is high, a ruthenium acid solution can be used to form a ruthenium dioxide protective film. When a citric acid solution is used, a predetermined amount of citric acid solution is added to the dispersion, and a base is added to adhere the citric acid solution to the surface of the porous particle. Further, a cerium oxide protective film may be produced by using a citric acid solution together with the above alkoxy decane. (Step 3: Formation of ruthenium dioxide coating layer) In the third step, the porous particle dispersion (the cavity particle precursor dispersion in the case of void particles) prepared in the second step is added with fluorine. The surface of the particles is coated with a polymer such as a hydrolyzable organic hydrazine compound or a citric acid solution to form a cerium oxide coating layer, in place of a hydrolyzable organic hydrazine compound or a citric acid solution of a decane compound of an alkyl group. Further, the slashing acid solution is obtained by subjecting an aqueous solution of a metal oxide such as water glass to an alkali-removed low-polymer aqueous solution of citric acid by ion exchange treatment. The addition of the organic cerium compound or the ceric acid solution for forming the coating layer -37-200907491 is only sufficient to coat the surface of the colloidal particles sufficiently, and the thickness of the cerium oxide coating layer finally obtained is 1 to 4 〇. The nm, preferably in an amount of from 1 to 20 nm, is added to the dispersion of the porous particles (the hollow particle precursor in the case of void particles). When the cerium oxide protective film is formed, the total thickness of the cerium oxide protective film and the cerium oxide coating layer is 1 to 40 nm, and it is preferable to add an organic cerium compound or a ceric acid cerium in an amount of 1 to 20 nm. Then, the dispersion of the particles forming the coating layer is heat-treated. By the heat treatment, in the case of the porous particles, the ceria coating layer covering the surface of the porous particles is densified to obtain a dispersion of the composite particles in which the porous particles are coated with the ceria coating layer. Further, in the case of a void particle precursor, the formed coating layer is densified to become a void particle wall, and a dispersion liquid having voids inside the cavity filled with a solvent, a gas or a porous solid component is obtained. The heat treatment temperature at this time is not particularly limited as long as it can block the pores of the ceria coating layer, and is preferably in the range of 80 to 300 °C. When the heat treatment temperature is less than 80 °C, the fine pores of the silica sand coating layer may be completely blocked, and the densification may not be performed, and the treatment time must be long. When the heat treatment temperature exceeds 3 〇 0 ° C for a long period of time, it becomes a dense particle, and the effect of lowering the refractive index cannot be obtained. The refractive index of the hollow cerium oxide-based particles thus obtained is lower when it is less than K 4 2 . It can be piled up such that the hollow ceria-based particles maintain the porosity inside the porous particles, but the internal refractive index is low, so that the refractive index is lowered -38-200907491 and as a stability when added to the coating composition From the viewpoint of the hollow particles of the nature, it is preferred that the polymer having a hydrocarbon main chain on its surface is a covalently bonded hollow particle. Continuing' the description of the hollow particles in which the polymer having a hydrocarbon backbone is easily covalently bonded. The polymer having a hydrocarbon main chain is a direct covalent bond, or a cerium oxide on the surface of the hollow cerium oxide-based particles and a polymer having a hydrocarbon main chain, and a binder is added to the cerium oxide and the binder. Covalent bonding means that it can also be said that the binding agent and the polymer are covalently bonded. It is preferred to use a coupling agent as a binder. The hollow particles in which the polymer having a hydrocarbon main chain is covalently bonded can be made into a hollow cerium oxide system by (1) treating the surface of the hollow cerium oxide-based particles with an untreated or a coupling agent. a method in which a particle surface is reacted with a polymer having a functional group capable of forming a covalent bond, a polymer is grafted on the surface of the hollow ceria-based particle, or (2) the surface of the hollow ceria-based particle is untreated In the state in which the coupling agent or the like is treated, a method of "polymerizing a monomer from the surface of the hollow ceria-based particle to grow a polymer chain" to carry out surface grafting or the like is produced.

The valence of the hydroxyl groups of the polymer X and the polymer Y is preferably from 3 to 10%. Wherein the determination of the hydroxyl number can be based on JIS K 0070. The hydroxyl value is defined as the number of mg of potassium hydroxide required for the sample lg to be subjected to acetic acid in which an ethyl group is bonded to a hydroxyl group. After X g (about 1 g) was accurately weighed in a flask, the reagent was correctly tested (add pyridine to 20 ml of acetic anhydride to make it into 20 ml. Install an air cooling tube at the mouth of the flask and heat it in 95~1. After 1 hour and 30 minutes, it was cooled, and the acetic anhydride was decomposed into acetic acid by 1 ml of pure water. Secondly, the device was measured as the end point of the titration curve of the titration curve of 〇.5 mol/L potassium hydroxide ethanol solution. The titration was carried out under the blank test, and the curve of the titration curve was obtained. The hydroxyl group was calculated. The hydroxyl value = { (BC) xfx 28.05/x}

Mw = proofreading curve from 13 samples of 1,000,000~5 00. The 13 samples used almost equal intervals. The total amount of the polymer X and the polymer Y is only 5% by mass or more, which is sufficient for the reduction of the enthalpy (Rt) in the thickness direction. Further, when the total amount is 36% by mass or less, the adhesion to the polarizer PV A is good. The polymer X and the polymer Y can be directly added, dissolved, or dissolved in an organic solvent in which a cellulose ester is previously dissolved, and added to the dope as a material constituting a slurry as described later. The total content of the above-mentioned plasticizer in the cellulose ester film is preferably 5 to 20% by mass, more preferably 6 to 16% by mass, even more preferably 8 to 13% by mass, based on the total amount of the solid content.

The polyol ester-based plasticizer is preferably 1 to 15% by mass, particularly preferably 3 to 11% by mass. When the content of the polyol ester-based plasticizer is too small, planarity is deteriorated, and when it is too large, it is easy to be extravasated. The mass ratio of the polyol ester-based plasticizer to the other plasticizer is preferably in the range of 1:4 to 4:1, and more preferably 1:3 to 3:1. If the amount of the plasticizer added is too large or too small, the film may be easily deformed. (solution casting film forming method) The cellulose ester film is produced by a solution casting film forming method in which a cellulose ester and an additive are dissolved in a solvent to prepare a dope, and the dope is transported. a step of casting on a metal support having a strip shape or a roll shape, and a step of drying the cast paste as a web -102 - 200907491, a step of peeling off from a metal support, and extending The step of maintaining the width, the step of further drying, and the step of winding up the processed film are carried out. First, the steps of preparing the glue are explained. The concentration of the cellulose ester in the plasticity is preferably such that the drying load after casting on the metal support can be reduced when the concentration is high, but if the concentration of the cellulose ester is too high, the load during filtration increases. The purity is deteriorated. The concentration which can be made two is preferably 10 to 35 mass%, more preferably 15 to 25 mass%. The solvent used in the dope may be used singly or in combination of two or more types. However, when a good solvent of a cellulose ester and a weak solvent are used after mixing, it is preferable from the viewpoint of production efficiency, and when the amount of a good solvent is large, cellulose is used. The viewpoint of the solubility of the ester is preferred. The mixing ratio of the good solvent to the weak solvent is preferably in the range of 7 to 98% by mass of the good solvent and 2 to 30% by mass of the weak solvent. The term "good solvent" or "weak solvent" is defined as a good solvent in which the cellulose ester used alone is dissolved, and a weak solvent in the case where it is swellable or insoluble. Therefore, the degree of substitution of the thiol group of the cellulose ester can be changed to a good solvent or a weak solvent. For example, when acetone is used as a solvent, the cellulose ester of the cellulose ester (acetamyl substitution degree 2. 4), cellulose acetate propionate becomes a good solvent, cellulose acetate (acetamyl substitution degree 2. 8) Become a weak solvent. The good solvent to be used in the present invention is not particularly limited, and examples thereof include an organic halogen compound such as methylene chloride or a dioxapentane group, acetone, methyl acetate, methyl ethyl acetate or the like. Particularly preferred are dichloromethane or methyl acetate. Further, the weak solvent used in the present invention is not particularly limited, and for example, methanol, ethanol, η-butanol, cyclohexane or cyclohexanone can be used. Also, in the glue -103- 200907491 contains water 0. 0 1 to 2% by mass is preferred. When the above-mentioned gel is prepared, it is used as a general method for dissolving a cellulose ester. When combined heating and pressurization, heating can be carried out under normal pressure. It is preferable to stir the dissolving gum or the undissolved matter called mamaco (caking) while heating the solvent at a temperature higher than the boiling point of the normal pressure and boiling. Further, it is also preferred to mix the cellulose ester with a weak solvent to make it wet, and to add a good solvent for dissolution. The pressurization can be carried out by a method of increasing the vapor pressure of the solvent by injecting an inert gas such as nitrogen. Heating is good, for example, a jacket type is preferred because it is easy to control the temperature. The heating temperature at which the solvent is added is preferably from the viewpoint of cellulose at a high temperature, and if the heating temperature is too high, productivity must be deteriorated. Preferably, the heating temperature is from 4 5 to 1 2 ° ° C, preferably from 70 ° C to 10 ° C. Also, the pressure can be adjusted to the extent that the solvent does not boil. Further, a cooling dissolution method may be used, whereby cellulose acetate is dissolved in the cellulose acetate. Further, the cellulose ester solution is suitably filtered using a filter paper or the like. As the filter material, it is preferable to remove the insoluble matter or the like, but the absolute filtration accuracy is too small, which is a problem. Therefore, the absolute filtration accuracy is 〇. 〇〇 8mm or less 0. 001~0. 008mm filter material is better, 0. 003~ The material is better. The method can be used for the boiling point or higher and does not cause the solvent to prevent the occurrence of coagulation. Therefore, the pressure after the swelling or the swelling of the ester can be excessively increased by 60 〜 11〇°. In the solvent such as ester at the set temperature, it is better to filter the filter material. The filter material is blocked by the filter material, 〇. 〇〇6mm filter -104- 200907491 The material of the filter material is not particularly limited, and it is preferable to use a filter material made of plastic such as olefin or Teflon (registered trademark) because no fiber is detached. The impurities of the cellulose ester are particularly removed or reduced. In the present specification, the so-called bright foreign matter is in the state of 2 Nichols, and the cellulose ester film is irradiated with light, and the light is leaked when viewed from the other polarizing plate side. Point (foreign matter), the diameter is 0. 01mm or more /em2 or less is preferred. It is preferably 1 〇〇/cm 2 or less, and particularly preferably 〇 10 pieces/cm 2 or less. Also, the points are also less good. The filtration of the dope can be carried out by a general method, and the method of filtering at a temperature above the boiling point and under the pressure of boiling without boiling the solvent can preferably reduce the increase in filtration before and after the filtration. The preferred temperature is 4 5 to 1 2 0. (: Good, 4 5~5 5 °C is better. Filter pressure is better. Filter pressure is 1. 6MPa or less is preferred, l. It is more preferable when it is below OMPa. Continue to explain the casting of the glue. The metal support surface processor in the casting (casting) step is preferred, and as the metal support, it is preferable to use a casting for surface plating. The casting width can be 1 to 4 m. The temperature of the casting step is set to -50 °C - the temperature at which the solvent is boiled and not foamed. Generally, the filter medium, polypropylene, or stainless steel is filtered, and the foreign matter contained in the raw material is preferred. The polarizing plate is arranged to be positive, from the side of one polarizing plate, the number of bright spots seen from the opposite side is 200, more preferably 50/m2 ’ 0.

When the temperature is higher -105-200907491, the drying speed of the web can be increased, so that the web is foamed or the flatness is deteriorated if it is too high. The temperature of the preferred metal support is preferably 0 to 100 ° C, more preferably 5 to 30 ° C. Further, it is also preferable to gel the web by cooling and to peel off from the metal support in a state containing a large amount of residual solvent. The method of controlling the temperature of the metal support is not particularly limited, but a method of blowing warm air or cold air or a method of bringing warm water into contact with the inner side of the metal support can be used. When warm water is used, heat can be efficiently transmitted, so that the temperature of the metal support reaches a certain period of time and is preferable. When using warm air, the temperature of the network may be lowered in consideration of the latent heat of evaporation of the solvent, and the use of warm air above the boiling point of the solvent may prevent foaming or use a wind higher than the target temperature. In particular, it is preferable to carry out drying efficiently from the time of self-casting to peeling, changing the temperature of the metal support, and the temperature of the dry wind. In order to make the cellulose ester film exhibit good planarity, the residual solvent amount when the mesh is peeled off from the metal support is preferably from 10 to 150% by mass, more preferably from 20 to 40% by mass or from 60 to 130% by mass. , particularly preferably 20 to 30% by mass or 7 0 to 1 2 0% by mass.

Better, better is 0. 1% by mass or less, particularly preferably 0 to 0. 0 1% by mass or less. In the film drying step, it is generally carried out by a roll drying method (a method in which a plurality of rolls disposed on the upper and lower sides are passed through a web and dried by a web) or a tenter method to carry out drying under a mesh. When the cellulose ester film used in the anti-glare film of the present invention is to be produced, the amount of residual solvent remaining in the mesh after peeling from the metal support is immediately extended in the transport direction, and the ends of the mesh are It is particularly preferable to extend in the width direction by a tenter clamped by a press plate or the like. The preferred stretching ratio of both the longitudinal direction and the lateral direction is 1. 01~1. 3 times, more preferably 1 . 05~ 1. 15 times better. Extend the area by 1 by extending in the longitudinal direction and the lateral direction. 12~1. 44 times is better, become 1 . 15~1·32 times is better. This can be obtained by the stretching ratio in the longitudinal direction of the stretching magnification X in the horizontal direction. The extension ratios in the longitudinal direction and the horizontal direction are all less than one. Ultraviolet irradiation at the time of forming a hard coat layer at 0 times causes flatness deterioration. It is preferable to extend in the longitudinal direction immediately after peeling, and it is preferable to extend by the peeling tension and the conveyance tension thereafter. For example, the peeling tension is preferably 2 1 ON/m or more, and the peeling is preferably carried out, and particularly preferably 220 to 3 OON/m. The means for drying the web is not particularly limited, and it can be generally carried out by hot air, infrared rays, heating rolls, microwaves, etc., but from the viewpoint of convenience, it is preferable to carry out hot air.

It is also excellent, so the film thickness of the cellulose ester film is particularly preferably 10 to 70 μm. More preferably 20~60μηι. The best is 35~60μηι. Further, a cellulose ester film composed of a plurality of layers of a co-casting method may also be used. In the case where the cellulose ester has a multilayer structure, it also has a layer containing an ultraviolet absorber and a plasticizer, which may be a core layer, a surface layer, or both. The antireflection film of the present invention has a width of lm or more and a width of 1. 4 ~ 4m is better. Very good for 1 . 4~3m. When it exceeds 4m, it is difficult to transport. Further, the average center-to-center thickness (Ra) of the surface of the hard coating layer provided with the cellulose ester film can be 0. 001~Ιμιη. (Melt Cast Film Forming Method) The cellulose ester film can also be preferably formed by a melt casting film forming method.

When a mixer is used, a general mixer such as a V-type mixer, a conical spiral type mixer, a horizontal cylinder type mixer, a Henschel mixer, or a ribbon mixer can be used. After the film constituting material is mixed as described above, the mixture can be directly melted using an extruder to form a film. 'But once the film constituting material is granulated, the granules can be melted by an extruder to form a film.

As a film constituting material, -109- 200907491 When a granule or a rice pass semi-melt is used, a uniaxial extruder can be used, and a 2-axis extruder can also be used. The cooling step in the extruder and after the extrusion may be replaced by an inert gas such as nitrogen or the pressure may be lowered to reduce the oxygen concentration. The melting temperature of the film constituent material in the extruder varies depending on the viscosity or the amount of the film constituent material, the thickness of the sheet to be produced, and the like, but generally, the glass transition temperature (Tg) of the film is Tg or more. , Tg + 100 ° C or less, preferably Tg + 10 ° C or more, Tg + 90 ° C or less.
