    摘要: A heat transfer image-receiving sheet including a substrate sheet and a dye-receiving layer formed on at least one surface of the substrate sheet. The dye-receiving layer of this heat transfer image-receiving sheet is composed of a resin containing a polar group and/or a salt thereof in an amount of 2 to 2000 equivalents per 10.sup.6 g of the resin. With the dye-receiving layer comprising the resin, a heat transfer image-receiving sheet, which can form thereon an image having a high density and good preservability, is provided.

    摘要: A heat transfer sheet including a substrate film and a dye layer including a dye and a binder formed thereon, wherein the binder includes organic-solvent-soluble polymers having ester moieties and/or urethane moieties, prepared by modifying water-soluble natural and/or semisynthetic polymers by esterifying and/or urethanating an inner hydroxyl group thereof, and the dye includes a sublimable dye homogeneously dissolved in the binder. A heat transfer sheet is also disclosed which includes a substrate film, and a dye layer formed thereon, wherein the dye layer includes (i) a binder which is cellulose acetate having an acetylation rate of 2.4 or more and a total substitution rate of 2.7 or more, and (ii) a sublimable dye dissolved in the binder. The sublimable dye contained in the dye layer is not separated from the binder even when the heat transfer sheet is preserved for a long period of time. Furthermore, the heat transfer sheet can produce a high-density image even when only a small amount of thermal energy is applied thereto.
