用いられている。In recent years, as a recording method for directly recording an image such as a photograph from an image on a CRT display, a thermal transfer sheet is heated by a thermal head whose heat generation is controlled by an electric signal, and A thermal transfer recording system is used in which a sublimable dye is transferred onto a heat transfer target sheet to record image information. This thermal transfer recording system has been attracting attention as a system capable of transferring and recording a color image having continuous changes in color tone by performing overlapping recording of cyan, magenta, and yellow. As a thermal transfer recording sheet used in the thermal transfer recording method, conventionally, a substrate having a surface coated with a polyester resin to form an image receiving layer on which a sublimable dye is transferred is used.
しかしながら、従来の被熱転写シートでは転写された画

ルギーを印加して染料を昇華転写せしめる昇華転写法で

れるために光の影響を受け易いためと考えられる。However, the conventional heat-transferable sheet has a drawback that the transferred image is poor in light resistance, the clarity of the transferred image is lowered during storage, and a beautiful image cannot be maintained for a period of time. It is considered that this is because the dye is transferred to the vicinity of the surface of the image receiving layer of the heat-transferred sheet in the sublimation transfer method in which energy is applied in a short time to sublimate and transfer the dye by the thermal head, which is considered to be easily affected by light. .

に比べて劣るという問題があった。As a result of diligent research conducted by the present inventors to solve the above problems,
It has been found that when the image receiving layer is composed of a vinyl chloride-vinyl acetate copolymer, the light resistance can be remarkably improved, but when the image receiving layer is composed of only a vinyl chloride-vinyl acetate copolymer, the transferred dye Has a disadvantage that the transfer dye is retransferred to the paper when the paper is brought into contact with the image receiving layer surface of the heat transfer sheet after transfer and stored.
There is also a problem that the recording sensitivity is inferior to that in the case where the image receiving layer is made of polyester alone.

What is used. If the vinyl chloride component of the vinyl chloride-vinyl acetate copolymer is less than 85 wt%, the light resistance is poor and the sensitivity is also reduced.On the other hand, if the vinyl chloride component exceeds 97 wt%, the solubility of the resin in the solvent is reduced and it is a general-purpose solvent. I will not be able to coat. Further, if the degree of polymerization of the vinyl chloride-vinyl acetate copolymer is less than 200, the coating film strength may be lowered and the surface may be roughened, while the degree of polymerization is 80.
If it exceeds 0, the compatibility with saturated polyester deteriorates,
Layer separation occurs, and it becomes difficult to obtain a uniform and good film, and there is a possibility that a uniform image receiving layer cannot be formed. The vinyl chloride-vinyl acetate copolymer is not necessarily a photopolymer of only a vinyl chloride component and a vinyl acetate component, and may contain a vinyl alcohol component, a maleic acid component, etc. within a range not hindering the object of the present invention. It may be. Examples of such vinyl chloride-vinyl acetate copolymers include S-REC A, S-REC C, S-REC M (all manufactured by Sekisui Chemical Co., Ltd.),

With this configuration, it is possible to transfer and record an image with high sensitivity and excellent sharpness, and the retransferability of the transferred image is small, so when the heat transfer sheet is overlaid with paper after transfer. However, there is no risk that the sublimable dye will be retransferred to paper or the like to cause contamination. Moreover, since the transferred image on the image receiving layer has excellent light resistance, the color deterioration of the transferred image is extremely small, and the image sharpness can be maintained for a long period of time to be substantially equal to that immediately after the transfer. Have. Further, the heat-transferable sheet of the present invention has sufficient light resistance and sensitivity since the vinyl chloride component of the vinyl chloride-vinyl acetate copolymer used for the image receiving layer is in the range of 85 to 97 wt, and has good solubility in a solvent and is widely used. It can be coated with a solvent. Further, since the degree of polymerization of the vinyl chloride-vinyl acetate copolymer of the image-receiving layer is 200 to 800, the coating film strength is sufficient and the compatibility with the saturated polyester is also sufficient to prevent layer separation and the like. A uniform and good image receiving layer can be formed.
