Abstract
A thermal transfer recording material comprising a foundation and, provided thereon, a heat-meltable ink layer comprising at least an epoxy resin, a coloring agent and a particulate polytetrafluoroethylene, the epoxy resin comprising not less than 50% by weight of at least one member selected from the group consisting of tetraphenolethane tetraglycidyl ether, cresol novolac polyglycidyl ether, bisphenol A diglycidyl ether and bisphenol F diglycidyl ether, the content of the particulate polytetrafluoroethylene in the heat-meltable ink layer being from 1 to 60% by weight. The recording material exhibits satisfactory transferability and gives printed images having excellent scratch resistance.
