PROBLEM TO BE SOLVED: To satisfy relasability of a heat meltable ink layer and fixability and fastness of a transfer image by incorporating ethylene-silicon-ethylene copolymer represented by a specific formula in a release layer, in a thermal transfer recording medium having the release layer between a base material sheet and a heat meltable ink layer. SOLUTION: In the thermal transfer recording medium comprising a release layer between a base material sheet and a heat meltable ink layer to be suitably used in the case of orienting a bar code on a corrugated fiberboard case by a heating time release type, the release layer is formed by incorporating ethylene-silicon-ethylene copolymer represented by the formula in the layer. In for formula, R1 , R2 indicate 1-1,000C hydrocarbon groups, m indicates integers of 0 to 1,000, and n indicates integers of 2 to 60. 10<=m/(m+n)<=0.6 is satisfied. The ink layer mainly contains a coloring agent, wax and a resin. Preferably, 0 to 50wt.% of the agent, 5 to 50wt.% of the resin and 20 to 60wt.% of the wax are contained. |
