Zusammenfassung:PURPOSE:To enhance resolving power and high speed followability by compounding a plurality of specific ethylene/vinyl acetate resins with a specific isocyanate polymer and successively laminating a specific thermal transfer ink layer and a specific coating layer on a base material. CONSTITUTION:An ethylene/vinyl acetate resin A with a number average mol.wt. of 14500-15500 and an ethylene/vinyl acetate resin B with a number average mol.wt. of 16500-17500 are compounded with a isocyanate compd. of lanolin fatty acid polyhydric alcohol having melt viscosity of 3000-50000 at 100 deg.C so that an A/B ratio is 30/70-70/30. However, the total compounding amt. of A and B is 15-60% by wt. of a binder excepting a coloring component. A thermal transfer ink layer with which a coloring component is compounded as an essential component is formed on a base material through a wax release layer and a coating layer having cohesive force higher than that of the thermal transfer ink layer is arranged on the surface of the thermal transfer ink layer.
