(Industrial Application Field) The present invention relates to an image receptor as a transfer target for a thermal transfer medium using a sublimable dye. (Prior art and its problems) An image receptor for forming a transferred image from a heat-sensitive transfer medium containing a sublimable dye in a heat-sensitive transfer layer has good dyeability, light fastness, and chemical resistance. , abrasion resistance and properties to prevent blocking (resin film peeling) during printing on thermal transfer media and image receptors are required. Furthermore, in recent years, the application of heat-sensitive transfer media using sublimation dyes has rapidly expanded to convert information from video signals into images, and the storage stability of the images, especially plasticizer resistance and dye migration resistance, has increased rapidly. Improvement is required. In order to successfully transfer and develop the sublimable dye of the thermal transfer medium onto the image receptor side, the resin on the image receptor side needs to have good dyeability with respect to the sublimable dye. The dyeability of the resin is better as the softening point and glass transition point are lower. However, such resins that have good physical properties and good dyeability tend to fuse with the resin that holds the sublimable dye of the thermal transfer medium during thermal transfer, causing blocking, and furthermore, once dyed, the sublimable dye is reused. The drawback is that it easily sublimes, resulting in image deterioration. Blocking development during thermal transfer is also related to the amount of resin applied to the transfer medium, but in particular, in order to prevent blocking from the dye transfer medium side to the receiver side, it is necessary to take some measures to the resin layer of the image receiver. . An example of this would be to harden the surface resin layer of the image receptor to make it heat resistant.
In this case, the sublimable dye on the transfer medium side becomes difficult to dye onto the image receptor side, resulting in a decrease in image density. It is also possible to activate the surface of the image receptor by mixing an additive such as silicone oil into the resin layer of the image receptor or applying silicone oil or the like to the resin surface of the image receptor. It is viscous, easily smudged, and has problems in terms of fingerprint resistance. In this way, there is a contradictory relationship between good dyeability of the sublimable dye from the transfer medium to the image receptor side and the storage stability after dyeing, and there is currently no concrete solution. . (Object of the Invention) The present invention has been made in view of the above circumstances, and is capable of producing high-density dye transfer images without causing resin transfer from a thermal transfer medium containing a sublimable dye in the thermal transfer layer. The purpose of the present invention is to provide an image receptor for thermal transfer that can be formed and has excellent fingerprint resistance and storage stability. (Means for Solving the Problems) As shown in FIG. 1, the thermal transfer image receptor of the present invention has a substrate 1 made of paper, plastic, an inorganic sheet, etc., and has a good dyeing property for sublimable dyes. At least a dyed image-receiving layer 2 having adhesive properties is formed. The dyed image-receiving layer 2 is mainly made of a thermoplastic polyester resin having four or more hydroxyl groups, a tensile strength at break of 300 Kg/cm 2 (ASTM D638) or more, and a tensile elongation at break of 20% or more (ASTM D638). The composition further contains a dye-permeable mold release agent made of an addition reaction or condensation reaction type softening silicone resin. The reason why the dyed image-receiving layer 2 is configured in this way is that there is no transfer of resin from the thermal transfer medium side, which includes a sublimable dye in the transfer layer, to the image receptor side during thermal transfer. In addition, even though the dyeable resin has a high softening point and high glass transition point, it has a low softening point and glass transition point and has the same level of dyeability as a resin with good dyeability. This is so that they can have sex. Such a dyed image-receiving layer 2 is made of an addition reaction or condensation reaction type curable silicone resin (silicone 1 per 100 parts of resin solids
~2 parts (solid content) of catalyst) may be mixed in an amount of 5 to 15 parts, and may be formed with a thickness of 4 to 6 μm. Inorganic filler fine powder may be added to this dyed image-receiving layer 2. Table 1 shows the improvement in anti-blocking properties, dyeability, and storage stability when addition reaction or condensation reaction type curable silicone resins are added to thermoplastic polyester resins with different tensile strength and elongation at break. A comparison is shown with a case where no silicone resin is added.

た。[Table] For parts As understood from Table 1, even if addition reaction or condensation reaction type silicone resin is contained in thermoplastic polyester resin, if the polyester resin has 4 or more hydroxyl groups, Moreover, when the tensile strength at break is 300 Kg/cm 2 (ASTM D 638) or more and the tensile elongation at break is 20% or more (ASTM D 638), the peeling action of the silicone resin causes the release of the heat-sensitive transfer layer. The binder resin is not transferred or fused to the dyed image-receiving layer 2 during thermal transfer, and only the dye can be efficiently transferred into the dyed image-receiving layer 2, and the dyeing properties of the above-mentioned specific physical properties are improved. Due to the selection of the resin, it is possible to further improve the density of the transferred image, the storage stability after dye transfer, especially the light resistance and plasticizer resistance.
