PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive sheet for heat-sensitive transfer printing, which includes a release layer having sufficient fixing property to an OPP film (oriented polypropylene film) as a substrate and good releasing property with respect to a pressure-sensitive adhesive layer, and has excellent adhesiveness to a color layer to be thermally transferred onto a print object face that is the surface of the release layer.SOLUTION: A release layer comprising an acid-modified polyolefin resin and silicone oil, the surface of which is to be printed by a heat-sensitive transfer medium, is formed on a surface of an OPP film as a substrate. The silicone oil is preferably a modified silicone oil prepared by modifying at least a part of methyl groups of dimethyl silicone oil with at least one nonreactive group selected from a group consisting of an alkyl group having 2 or more carbon atoms, an aralkyl group, a polyether group, and a higher alcohol ester group. |
