ABSTRACT:
A thermal image transfer recording medium includes a substrate, a thermal image transfer ink layer provided on the substrate, and a heat resistant protective layer which is provided on the back side of the substrate, opposite to the thermal transfer ink layer with respect to the substrate, with which a thermal head comes into contact. The heat 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 heat resistant protective layer has a contact angle with pure water of 95.degree. or more and a dynamic coefficient of friction of 0.07 or less. The heat resistant protective layer may also be made of a modified copolymer containing (a) a main backbone chain polymer including an 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.
