    摘要: The present invention relates to an apparatus for forming required images on an objective body, comprising in combination: means for processing image data fed thereto; means for forming images, on the basis of image data, on an image-receiving sheet for image transfer by reliance on a sublimation image transfer system; and means for transferring said images formed on said image-receiving sheet onto the surface of an objective body. The apparatus can further comprise means for transferring the image-reception layer of the image-receiving sheet which has been subjected to image forming operation once onto an intermediate transfer substrate; and means for retransfer of the image-reception layer stuck on said intermadiate transfer substrate onto said objective body. Furthermore, the image data processing means can be provided with image reversing means.

    摘要: A heat transfer sheet comprises a substrate sheet and a heat transfer layer laminated on the substrate sheet and containing a dye which can be caused to migrate by heating to be transferred onto a transferable sheet, said heat transfer sheet containing a polyvinyl acetacetal resin as a binder component, the acetal moiety of said polyvinyl acetacetal resin being 50% by weight or more based on the total amount of the resin, and 80% by weight or more of said acetal moiety comprising polyvinyl acetacetal. A process for producing a polyvinyl acetacetal resin by the reaction of a polyvinyl alcohol and acetaldehyde in an aqueous phase in the presence of 4 to 10% by weight of an acid catalyst comprises initiating precipitation of an acetalated product by maintaining the reaction system at a temperature of 8 to 17°C for 30 minutes or longer, and then maintaining said reaction at a temperature of 25 to 40°C.
