If the average particle size is less than 0 · 1 // m, the dispersibility becomes extremely poor, which will cause particle agglomeration, cause trouble in the manufacturing process, form coarse protrusions on the film, and possibly become a film with poor gloss. On the other hand, if it exceeds 0.5 μm, the surface of the film becomes rough and the gloss is reduced. If the added amount is less than 5% by weight, it becomes a film with poor concealability, and a good product cannot be obtained.

Biaxially oriented polyester of the present invention The thin film is produced according to the aforementioned method 'to produce an aromatic polyester containing titanium dioxide particles or mixed particles of titanium dioxide particles and other inert particles, which can be obtained by stretching and heat treatment by a film forming method described later. As for the film forming method and The conditions are as described below, but the physical properties of the biaxially oriented polyester film of the present invention are explained first. The biaxially oriented polyester film of the present invention has an average gloss of 6 5 · 0 to 95 · 0%, preferably 70. ~ 90%. If the average gloss is less than 65%, the gloss will decrease, so it is not suitable as a substrate for inkjet printers. On the other hand, if the average gloss exceeds 9 5%, although the gloss is sufficiently satisfactory, the surface of the film becomes too flat and the film is inferior in transportability. The biaxially oriented polyester film of the present invention has a thickness of 50 to 2 5 0 // m, and preferably ranges from 60 to 2 20 #m. The biaxially oriented polyester film of the present invention is an X-ray diffraction intensity ratio (

FF — 2) Within the range of the following formula (1) 05 ^ F-1 / F- Please read the note on the back page δ printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs (in the formula, F-1 indicates that the The X-ray diffraction intensity obtained from the (1 10) plane of the surface, and F-2 represents the X-ray diffraction intensity obtained from the (1 0 0) plane parallel to the film plane).

The aforementioned X-ray diffraction intensity ratio (F F — 2) is in a range of 0.05 to 0.15, and preferably in a range of 0.07 to 0.12. When this X-ray diffraction intensity ratio is set to the above-mentioned range, the stretching temperature and magnification of the film in the film-forming step of the film selection step can be selected from the range described below. 297 mm) -9-546204 Α7 Β7 V. Description of the invention (7). When the X-ray diffraction intensity ratio is less than 0 · 05, the film forming stability is lowered. On the other hand, when the X-ray diffraction intensity ratio exceeds 0 · 15, the average gloss of the film decreases. The biaxially oriented polyester film of the present invention is a static friction coefficient of 0.3 to 0.6, preferably in a range of 0.31 to 0.67. When it is set to this range, it can be achieved in polyester by adding the aforementioned addition amount of dioxin particles and other inert particles. When the static friction coefficient of the film is less than 0 · 3, the gloss of the film is reduced, and when it exceeds 0 · 6, the transportability of the film is reduced. The biaxially oriented polyester film 'of the present invention has a small thermal shrinkage when heat-treated at 150 ° C for 30 minutes, and its 値 is less than 2%, preferably less than 1%. When the thermal shrinkage exceeds 2%, it becomes unsuitable as a substrate for developing an inkjet printer. Furthermore, the centerline of the biaxially oriented polyester film 'of the present invention on its surface has an average roughness (Ra) of 30 to 100 nm, and preferably a range of 35 to 80 nm. In the present invention, although it is a subject to provide a film with a high average gloss, the average gloss is the addition of the aforementioned titanium dioxide and other emotional particles or the type of other inert particles, and it is also related to the molecular orientation of the film . Specifically, the molecular orientation coefficient (MOR) is in a range of 1.1 to 4 · 〇, and preferably in a range of 1.2 to 3.8. When the molecular orientation coefficient (MOR) is set to the above range, it can be obtained by selecting the stretching conditions to be described later, in particular, the stretching ratio in the vertical and horizontal directions. Although the relationship between orientation and average gloss is not clear, the lubricant added to the film through high orientation is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm).

As a result, it can be estimated that the average gloss of the base film will become high. Therefore, a film with a MOR of less than 1 causes the average gloss to decrease due to low orientation, and the thickness of the film is also poor, which is not suitable for use as a product. On the other hand, when MOR exceeds 4.0, it becomes a highly oriented film, so film forming stability is poor and productivity is poor. The biaxially oriented polyester film of the present invention is used in the developing substrate of an inkjet printer, and is white in color, and its average glossiness is in the aforementioned range. However, it is preferable that the optical density satisfies the optical density of 0.7 to 1.6. range. The range related to this optical concentration can be achieved by selecting the added concentration of titanium dioxide particles. When the optical density is less than 0 · 7, the concealment is insufficient, and it is not suitable to see through the knowledge side. On the other hand, it is necessary to increase the concentration of nitric oxide particles to more than necessary in the production of thin films of more than 1.6. As a result, the strength of the thin film becomes weaker, and the film forming properties are difficult, which is not suitable. As described above, the thin film of the present invention is white, and the degree of whiteness' is expressed by the brightness (L *) and color (c *) specified by C I E 1 976, so as to satisfy the following formulae (1) to (3).

On the other hand, when it is more than 95 mol%, the adhesion to the inkjet developing layer is lowered. In addition, those having a cationic modification with a degree of saponification of polyvinyl alcohol of 74 to 91 mol% are preferred because the adhesion to the inkjet developing layer is good. The polyvinylpyrrolidone-based K has a valence of 2 6 to 100. When the K price is less than 26, the strength of the coating film is weak, so it is not suitable. When the K value exceeds 100, the adhesiveness to the inkjet developing layer is lowered, which is not suitable. Polyvinylpyrrolidone is preferable because it has an average molecular weight of 40, 000 or more, but it is superior in cutting resistance of the coating film of the coating film layer.

Next, the aforementioned method for forming the white biaxially-oriented polyester film of the present invention and the method for layering the coating film layer will be described. The polyester film of the present invention is a polyester composition containing titanium dioxide particles, and it can be produced by using such a composition by a known film forming method such as a tenter method or an inflation method. I. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. It should be the film forming method using the tenter method. As for the means, a sequential biaxial stretching method and a simultaneous biaxial stretching method can be mentioned. The following is a detailed description of the sequential biaxial stretching method. First, after the polyester composition is dried, it is melted at a temperature above the melting point, and extruded from a slit of a narrow bark onto a pre-cooled drum and quenched to produce an undrawn sheet. This sheet is heated by roller heating, infrared heating, etc., and stretched in the longitudinal direction to obtain a longitudinally stretched film. The longitudinal stretching is preferably performed using a peripheral speed difference of two or more rollers. The longitudinal stretching temperature is preferably a temperature higher than the glass transition temperature (Tg) of the polyester, and a temperature higher than Tg by 20 to 40 ° C. The draw ratio is based on the characteristics required for this application, but it is advisable to set the draw ratio to 2.5 to 4 times or less. In addition, it is preferable to set it to 2 · 8 times or more and 3 · 9 times or less. When the thickness is less than 2.5 times, the thickness unevenness of the film is deteriorated, and a good film cannot be obtained. When the thickness is more than 4.0 times, there is a problem that cracking easily occurs in the film formation. The longitudinally stretched film is then sequentially stretched, heat-fixed, and thermally relaxed as necessary to serve as a biaxially oriented film. However, these processes cause the film to travel while being performed online. The horizontal extension is a temperature that is 20 ° C higher than the glass transition temperature (T g) of polyester. The paper dimensions are applicable to China National Standard (CNS) A4 (210 X 297 public love) -16- 546204 A7 B7 V. DESCRIPTION OF THE INVENTION (14) begins. Therefore, heating is performed to a temperature lower than the melting point (T m) of the polyester (120 to 30) ° C, and the heating is performed. The stretching start temperature is below (D g + 40) ° C. The maximum stretching temperature is preferably lower than Tm (100 to 40) ° C. The temperature rise during the transverse stretching can be continuous or stepwise (gradual). Normally, the temperature rises gradually. For example, the transverse stretching area of the tenter is mostly distinguished along the film walking direction, and each area is heated by a heating medium with a predetermined temperature. If the transverse stretching start temperature is too low, the film may be cracked, which is not preferable. If the maximum stretching temperature is lower than (Tm-1 2 0) ° C, it is not suitable for the film to have a large thermal shrinkage and decrease the uniformity of the physical properties in the width direction. On the other hand, if the maximum tensile temperature is higher than (butyl m-3 0) t, the film will become soft, and the film will be cracked due to external interference, which is not suitable. The transverse stretching ratio is preferably 2.5 to 4.0 times. It is more preferably 2.8 times or more and 3.9 times or less. If the thickness is less than 2.5 times, the thickness unevenness of the film is deteriorated, and a good film cannot be obtained. If the thickness is more than 4.0 times, there is a problem that cracks are liable to occur during film formation. In the present invention, although a coating film layer made of the aforementioned components is laminated on at least one side of a white polyester film, for example, an aqueous solution containing a component forming a coating film layer is applied to a stretchable polyester film, and then dried, It is stretched, and may be laminated by heat treatment if necessary. The solid content concentration of this aqueous solution is usually 30% by weight or less, and more preferably 10% by weight or less. The stretchable polyester film is an unstretched polyester film, a uniaxially stretched polyester film, or a biaxially stretched polyester film. Among these, a longitudinally stretched polyester film that has been uniaxially stretched in the extrusion direction (longitudinal direction) of the film is particularly preferred.

Description of the Invention (15) Use the usual coating procedure That is, if it is performed on a polyester film that has been biaxially stretched and thermally fixed in a step separate from the manufacturing step of the film, it will easily become involved in dust and the like, which is not suitable. From a related point of view, it is suitable to apply under a clean atmosphere, that is, to apply in the manufacturing step of a thin film.
