PURPOSE:To improve repeatability in the case of using a thermal transfer ink layer containing a wax having urethane linkage by a method wherein said ink layer of a thermal transfer ink sheet that can be repeatedly used contains the wax having urethane linkage, and an intermediate adhesive layer contains a vinyl chloride-vinyl acetate copolymer. CONSTITUTION:A thermal transfer ink sheet is formed by successively laminating an intermediate adhesive layer 2 and an ink layer 3 on a substrate 1 and capable of being repeatedly used. The ink layer 3 of the thermal transfer ink sheet contains a wax having urethane linkage, and the intermediate adhesive layer 2 contains a vinyl chloride-vinyl acetate copolymer. In this construction, a stable and satisfactory repeatability can be realized even when the wax having urethane linkage is contained in the thermal transfer ink layer 3. The thermal transfer ink sheet having a favorable film forming capacity given by the ink layer containing the wax having urethane linkage can be repeatedly used. |
