Abstract

Abstract A thermal transfer image-receiving sheet comprising a substrate sheet, a dye-receptive layer provided on one surface of the substrate sheet and a dye-unreceptive layer provided on the other surface of the substrate sheet, the dye-unreceptive layer comprising a composition composed mainly of at least one thermoplastic resin having at least one reactive functional group and an isocyanate compound or a chelate compound. A thermal transfer image-receiving sheet comprising a substrate sheet, a dye-receptive layer provided on one surface of the substrate sheet and a dye-unreceptive layer provided on the other surface of the substrate sheet, the dye-unreceptive layer comprising a release agent which is the same as that contained in the dye-receptive layer or does not migrate to other places, for example, comprises an amino-modified silicone and an epoxy-modified silicone or a product of a reaction of both of them, or an addition-polymerizable silicone or a cured product obtained by a reaction thereof. A thermal transfer image-receiving sheet comprising a substrate sheet, a dye-receptive layer provided on one surface of the substrate sheet and a lubricious back surface layer provided on the other surface of the substrate sheet, the lubricious back surface layer being composed mainly of a binder and a nylon filler.
