The present invention provides a protective layer transfer sheet which, when used to thermally transfer a protective layer onto an image-receiving sheet with an image formed thereon, provides a print that does not cause cracking of the protective layer and, even when housed and stored in a vinyl chloride case containing a plasticizer or the like, does not cause the migration of a dye constituting the image to the case, that is, has excellent fastness properties. In a protective layer transfer sheet 7 comprising a substrate sheet 1, a heat-resistant slip layer 3 provided on one side of the substrate sheet 1, and a thermally transferable protective layer 2 releasably provided on at least a part of the surface of the substrate sheet 1 remote from the heat-resistant slip layer 3, the thermally transferable protective layer 2 contains an epoxy resin and, in addition, contains at least one member selected from the group consisting of a butyral resin, an acrylic resin, and an ultraviolet absorber. By virtue of this construction, a protective layer 2 is strongly adhered onto an image-receiving sheet with an image formed thereon. Further, the protective layer 2 is strong and homogeneous, and, thus, even when the print is housed in a vinyl chloride case, the print does not cause the dye to migrate to the case, that is, has excellent plasticizer resistance.
