しめて熱転写シートとの剥離性改善を図っている。In recent years, as a recording method for recording images such as photographs directly from images on a CRT display, the thermal transfer sheet is heated by a thermal head whose heat generation is controlled by an electric signal, and sublimation in the color material layer of the thermal transfer sheet is performed. A thermal transfer recording system has been adopted in which a functional dye is transferred onto a 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 transfer of cyan, magenta, and yellow. The thermal transfer sheet used in the thermal transfer recording system is generally constituted by coating a thermoplastic resin on the surface of a base material to form an image receiving layer to which a sublimable dye is transferred, but the image receiving layer is composed of only the thermoplastic resin. When configured, there is a drawback that the thermal transfer sheet is easily fused to the image receiving layer of the thermal transfer sheet when heated by being superposed on the thermal transfer sheet during transfer,
Therefore, in the conventional heat-transferable sheet, silicone oil is contained as a release agent in the thermoplastic resin constituting the image receiving layer to improve the releasability from the heat transfer sheet.

った。However, a conventional heat-transferable sheet having an image-receiving layer formed of a thermoplastic resin containing silicone oil in order to improve the releasability from the heat-transferable sheet at the time of transfer is a pencil on the surface of the heat-transferred sheet due to a decrease in surface writing characteristics. It has a drawback that it is difficult to write characters with a ballpoint pen or the like. In addition, when a conventional heat-transferable sheet is overlaid with other paper after transfer, the transferred sublimable dye is apt to be transferred from the heat-transferable sheet to the paper or the like, which easily causes contamination due to retransfer of the dye. Had. Moreover, the conventional heat-transferable sheet also has a problem in heat resistance. Therefore, although it contains silicone oil as a release agent, its releasability from the heat-transfer sheet is not always sufficient. Wearing is easy to occur,
There has been a problem that thermal transfer sheets are fused together during storage.

を有する。 [Effects of the Invention] As described above, the image-receiving layer on which the image is recorded by transferring the sublimable dye to the heat-transferable sheet of the present invention is composed of a thermoplastic resin containing silicone oil and a pigment. Excellent releasability from the thermal transfer sheet during transfer,
Writing on the surface of the image-receiving layer is possible without the risk of fusion between the heat-transfer sheet and the heat-transferred sheet and capable of transferring and recording an image with high definition, and containing a silicone oil as a release agent. Due to its excellent characteristics, characters and the like can be written on the surface of the image receiving layer with a writing instrument such as a ballpoint pen or pencil. Moreover, the heat-transferable sheet of the present invention is excellent in heat resistance and the re-transfer of the image transferred to the heat-transferred sheet is extremely small. Therefore, even when the heat-transferred sheets are stacked, the heat-transferred sheets are fused with each other. In addition, there is no fear that the sublimable dye will be retransferred to the paper or the like to cause contamination even when the heat-transferred sheet is overlapped with the paper or the like after the transfer. Further, the thermally transferable sheet of the present invention can change the gloss of the image receiving layer surface by changing the amount of the pigment contained in the image receiving layer,
The heat-transferable sheet can have different gloss depending on the purpose of use. Further, in the present invention, by using the pigment and the silicone oil in combination, as compared with the case where the pigment alone is added, sufficient releasability and writability can be obtained even when the addition amount of the pigment is small. If you do too much,
It has various effects such as preventing defects such as white spots during transfer.
