ABSTRACT:
A thermal image transfer recording medium comprising a support, and a thermal image transfer layer formed thereon, comprising as its main components an acrylic resin having a molecular weight of 1,000,000 or more and a glass transition temperature of 5.degree. to 60.degree. C., and a coloring agent. In the recording medium, a releasing layer comprising as its main component a wax having a melting point or softening point of 70.degree. to 120.degree. C. can be interposed between the support and the thermal image transfer layer; and an additional thermal image transfer layer comprising as its main component a thermoplastic resin whose glass transition temperature is equal to or higher than that of the acrylic resin contained in the thermal image transfer layer can also be interposed between the releasing layer and the thermal image transfer layer.
