摘要:
A cassette for heat transfer sheet, wherein a dislay means for displaying information concerning the number of recordable picture surfaces is provided on the outer surface of the cassette case of the cassette for heat transfer or on the heat transfer sheet housed within the cassette.
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 to be used for heat-sensitive transfer, comprising a substrate sheet and a dye layer formed on said substrate sheet, said dye layer being constituted of a layer containing a yellow dye, a cyan dye, and a magenta dye comprising a specific compound having phenylene-diamine or its derivative as the developer.
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.
