Abstract
A thermal transfer recording material comprising a foundation and a heat-meltable ink layer provided on the foundation, the heat-meltable ink layer comprising a heat-meltable vehicle and a coloring agent, the heat-meltable vehicle comprising at least one epoxy resin selected from the group consisting of tetraphenolethane tetraglycidyl ether, cresol novolac polyglycidyl ether, bisphenol A diglycidyl ether and bisphenol F diglycidyl ether, and a low melt viscosity substance, the epoxy resin and the low melt viscosity substance accounting for 50 to 95% by weight and 5 to 50% by weight, respectively, of the overall heat-meltable vehicle. The recording material exhibits satisfactory transferability and gives printed images having excellent scratch resistance.
