Abstract

PURPOSE:To ensure smooth feeding, by a construction wherein a thermal transfer layer is provided on one side of a plastic film, and a specified coating liquid is applied to the other side, followed by drying to provide a coated layer. CONSTITUTION:The thermal transfer layer is provided on one side of a plastic film, and a coating liquid containing a condensation polymerizable organometallic compound and a lubricant and/or a surfactant or a coating liquid containing a reaction product of the two components is applied to the other side, followed by drying to provide a coated film.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a thermal transfer material. More specifically, the present invention relates to a thermal transfer material that prevents fusion (stick phenomenon) between the thermal transfer material and a thermal head during printing and that runs smoothly.

[Conventional technology]

In recent years, with the advancement of office automation, various recording methods have been developed, and among these, thermal recording methods are attracting attention because they generate less noise during printing and are easy to operate.

Normally, a thermal recording method is used, in which a thermal head is brought into direct contact with thermal recording paper containing a special coloring agent. In this method, the operability of the thermal recording device,
Although it is excellent in maintainability, there is a major problem in long-term storage of records, as the recording paper discolors and shatters due to heat and light. In recent years, thermal transfer recording has been gaining attention and has begun to be widely used as a method that takes advantage of the advantages of thermal recording and eliminates the above-mentioned disadvantages. The thermal transfer recording method is likely to be used in various printers in the future because it can print on plain paper, has excellent long-term storage stability, and has excellent print quality. Examples of printers include computer printers, word processor printers, video printers, label printers, still video camera printers, and facsimiles. Furthermore, with the remarkable development of computers in recent years, it has become possible to easily display color graphics, and printers have also entered the age of colorization.

In this method, a heat-sensitive transfer material is used, which is composed of a base material, a heat transfer layer coated on the surface of the base material, and 1j'--. When printing, the recording paper (generally plain paper can be used) is brought into contact with the thermal transfer layer of the thermal transfer material, pressure is applied, the thermal head is brought into contact with the opposite side of the base material, and a pulsed signal current is applied to the head. Then, the thermal head is heated.@In this way, a heat-melting ink layer is transferred only from the heated portion of the thermal transfer layer, or sublimation ink is sublimated, and transfer recording is performed on the recording paper. Usually, a heat-melting ink layer is easily transferred to recording paper at an ink temperature range of 60C-/COC, and a sublimable ink layer is easily transferred to a recording paper at an ink temperature range of 70C-/COC.
Sublimation and transfer in the temperature range of θ℃. Generally, a method using the former is called a heat-melting type thermal transfer method, and a method using the latter is called a sublimation type thermal transfer method.

In the case of the hot-melt thermal transfer method, for solid black printing, a thermal transfer material with carbon black added to the ink layer is used.
For colorization, we use separate heat-sensitive transfer materials for the three primary colors of yellow, magenta, and cyan, and then thermally transfer them three times, once for each color, onto the same recording paper to overlap the three primary colors.

On the other hand, a major feature of the sublimation type thermal transfer method is that gradations can be easily produced, that is, the amount of sublimated ink can be easily controlled by the amount of heat of the thermal head. color v
If you want to make it darker, you can increase the applied voltage or lengthen the current pulse application time, and if you want to make it lighter, you can lower the applied voltage or shorten the current pulse application time. Taking advantage of the fact that this gradation can be easily produced, this method is applied to color printing, especially color printing of precise figures and photographs. The color printing method is
Similar to the heat-melting type, this method involves preparing heat-sensitive transfer materials for each of the three primary colors of yellow, magenta, and cyan, and performing thermal transfer once for each color, for a total of three transfers. In the case of the sublimation type thermal transfer method, as mentioned above, in order to deepen the color, it is necessary to increase the amount of heat of the head, and a temperature higher than the thermal melting temperature is applied to the thermal transfer material. When using sublimation ink in the thermal transfer method, a special image-receiving layer may be provided on the recording paper to ensure color stability and maintainability, but in general, the thermal transfer method uses plain paper. Since it can be easily recorded, the disadvantages of the thermal recording method can be eliminated.

Conventionally, capacitor paper has been used as the base material for this thermal transfer material, but it has low strength and is easily torn, and the base material needs to be made thinner in order to achieve high-speed printing and clear images. However, it has been proposed to use a thin film of plastic as the base material because it is difficult to reduce the thickness or reduce thickness unevenness in capacitor paper.

[Problem that the invention seeks to solve]

By the way, when a plastic film is used as a base material, the stick phenomenon described below occurs, which causes serious problems in its use.

That is, during recording, the surface temperature of the thermal head exceeds the melting point of the base plastic film, and the film that comes into contact with the thermal head fuses to the thermal head, resulting in a sticking phenomenon in which the feeding of the thermal transfer material is hindered. . The sticking phenomenon causes the recording to lose its sharpness, and the fused film is forced to come off, making a lot of noise. In extreme cases, the stick phenomenon causes the machine to stop running and cause operational problems. The stick phenomenon is
In particular, it is often found in sublimation type heat-sensitive transfer materials where the temperature of the thermal head is high.

[Means for solving problems]

In view of these facts, and as a result of intensive studies, the present inventor has determined that the above-mentioned interlacing point can be achieved by applying a coating liquid containing a specific compound to the surface opposite to the surface on which the thermal transfer layer is to be provided to form a coating film. The present invention was achieved by discovering that the problem can be solved.

That is, the present invention provides a thermal transfer layer on one side of the plastic, and a coating containing (A) an organometallic compound capable of degenerating and (B) a lubricant and/or a surfactant on the other side. A thermal transfer material is formed by applying a coating solution containing a liquid or a compound in which (A) and (B) have reacted and drying it to form a coating film.

U-shaped, m-shaped w plastic film in the present invention
Films made of Japanese polyester, polycarbonate, nylon, polypropylene, etc. and having a thickness of from 1 to 20 μm may be used. If the thickness is too thin, the fertility of the film itself will be compromised, and if it is too thick, there is no point in using a plus-snack film. Linear saturated polyester is particularly preferred from the viewpoint of heat resistance and strength. Linear saturated polyester is a crystalline linear saturated polyester synthesized from an aromatic dibasic acid or its ester-forming derivative and a diol, and includes polyethylene terephthalate, polyethylene isophthalate, polybutylene terephthalate, and polyethylene terephthalate. One example is 6-naphthalate.

Further, it may be a copolymer partially substituted with other components, or a blended material in which other resins such as polyethylene glycol or polycarbonate are distributed.

Usually, as the powdered saturated polyester film, it is possible to use a film with improved blocking properties that contains precipitated particles formed from inorganic particles such as calcium carbonate, kaolin, and silica, and catalyst residues used in the reaction. many.

When manufacturing a thermal transfer material, a thermal transfer layer is provided on the opposite side of the film to which it is coated.
When air charging occurs, coating unevenness occurs, which may cause a serious problem in that the thermal transfer layer cannot be coated uniformly.

In order to solve such problems, it is preferable to use polyester that has been subjected to antistatic treatment using a known method. For example, there is a method in which a polyester is made to contain a sulfonate represented by the following structural formula in an amount of 'pit:ai-,tx'.

There is no particular limit to the ratio of the lubricant etc. and the organometallic compound, but if the lubricant etc. has a reactive functional group, the lubricant etc. should be 7% to gθ% of the solid content. If it is too small, the lubricity and W&formability will not be exhibited, and if it is too large, the adhesion after 1 m of coating will be poor. When a lubricant or the like has a reactive functional group, its blending ratio can be increased. In particular, when reacting with an organometallic compound, the lubricant can be added up to t when the reaction is completed.

In the present invention, the coating method may be any known method as long as it can be applied thinly, and methods using a rod coater, gravure coater, various roll coaters, etc. are used.Furthermore, the thickness of the coating layer is usually,
0005μ to koμ. Preferably 0.0/μ~/
If the thickness is too thin, the lubricity will be poor, and if the thickness is to a certain extent, no greater thickness is required.

When using a biaxially stretched polyester film, the film AK may be applied after the crystal orientation has been completed, or it may be applied to the polyester film before the crystal orientation is completed, and then stretched, with or without drying. The crystal orientation may be completed by heat treatment.

In the latter case #II, taking the sequential biaxial stretching method as an example, longitudinal -
The axially oriented polyester film is coated with a coating solution (with or without drying as appropriate), then stretched in the transverse direction in a scissors tenter using moving clips, and heat treated. According to this method, it is possible to apply a coating layer and dry it at the same time as stretching, simplifying the operation, and
Since it is stretched after coating, the coating layer can be easily made thin.

Since the l1lI type property and slipperiness, which are effective in preventing the sticking phenomenon, are caused by the chemical properties and physical properties of the very surface layer of the film, it is important to keep the twisted layer as uniform and as thin as possible. If the coating layer is thick, the adhesion to the film is poor, and when the coating layer is wound into a roll, it has the disadvantage that the coating layer transfers to the opposite side. This method has the feature that a thin coating film can be easily formed. The heat treatment temperature in the above method is preferably about 0--SOC. In order to form a strong coating layer, high heat may be required, but in the method of coating biaxially stretched film, there is no equipment that is normally used to process at such high heat. Additionally, a device is required to prevent heat loss a of the film. However, in the above-mentioned method, high heat treatment can be easily performed, and if appropriate organometallic compounds and lubricants are selected, the high heat treatment results in extremely excellent adhesion to polyetherimide and excellent mold release properties. It is possible to produce a polyester film that has excellent properties such as lubricity and lubricity, and in which the coated layer does not transfer to the opposite surface.

The transfer layer of the thermal transfer material of the present invention is composed of a colorant and a binder. In the case of the heat-melting type thermal transfer method, as the colorant, pigments such as carbon black and various dyes widely used in the field of copying can be used. As the binder, carnauba wax, montan wax, microcrystalline wax, wood wax, oil-based synthetic wax, etc. can be used.

In the case of sublimation type thermal transfer method, sublimable dyes such as azo dyes and anthraquinone dyes are used as coloring agents, and carboxymethyl cellulose, methyl cellulose, ethyl cellulose, nitrocellulose, alginic acid derivatives, polysulfone, and polyether sulfone are used as binders. , polyarylate, polyetherimide, etc. In the present invention, if the adhesion of the coating film or thermal transfer layer to the 2MM stretched polyester film is poor, corona treatment or subbing coating treatment may be performed. .

〔Effect of the invention〕

When drying by heating at C, organometallic compounds in the coating solution,
The hydrolyzate or a low polymer of an organometallic compound forms a tightening body in the absence of a catalyst or in the presence of a catalyst such as acetic acid or sodium acetate, and forms a non-stick coating film, and can be used as a lubricant, etc. Since the lubricating portion reacted with the organometallic compound prevents the sticking phenomenon, it is possible to obtain a thermal transfer material that runs smoothly.
