摘要：A thermal image transfer recording medium includes a substrate, a thermalimage transfer ink layer provided on the substrate, and a heat resistant protective layerwhich is provided on the back side of the substrate, opposite to the thermal transfer inklayer with respect to the substrate, with which a thermal head comes into contact. Theheat resistant protective layer is made of an organic polymeric material free from cross-linking structure, with a film strength of 10 mN or more, and the surface of the heatresistant protective layer has a contact angle with pure water of 95° or more and adynamic coefficient of friction of 0.07 or less. The heat resistant protective layer may alsobe made of a modified copolymer containing (a) a main backbone chain polymer includingan active-hydrogen-containing polymer which encompasses no cellulose compounds and(b) a side chain polymer which is a copolymer of a reactive silicone and a vinyl monomer.
