Abstract
A thermal transfer material, comprising: a support, an intermediate layer and a heat-transferable ink layer disposed in the order named on the support. The intermediate layer comprises oxidized polyethylene having a number-average molecular weight of 1300-2500, and at least one species selected from polyoxyethylene alkylaryl ether, fatty acid, resin acid, amine and sulfuric acid ester salt. The thermal transfer material provides a transfer image of high density and clear edges without lacking even on a recording medium having poor surface smoothness.
