Abstract:
Provided is a protective layer transfer sheet which includes a protective layer, whereby it becomes possible to form an image on the protective layer set on a print without causing the abnormal transfer of a dye layer, the breakage of the dye layer and the like, and it also becomes possible to achieve a satisfactory level of plasticizer resistance of the print. The protective layer transfer sheet including a substrate and a protective layer peelably formed on the substrate, wherein the protective layer includes one or both of a cellulose ester having a number average molecular weight of not less than 15000 and not more than 30000 and a vinyl chloride-vinyl acetate copolymer having a number average molecular weight of not less than 15000 and not more than 30000, and a cellulose ester having a number average molecular weight of not more than 7000.
