PROBLEM TO BE SOLVED: To provide a heat-sensitive transfer recording medium which corresponds to such requirements as speedup of printing speed of thermal transfer and high density and high quality of a thermal transfer image, prevents the occurrence of abnormal transfer and is improved in transfer sensitivity in printing.SOLUTION: There is provided a heat-sensitive transfer recording medium 1 which comprises a heat-resistant lubricative layer 40 on one surface of a substrate 10 and an undercoat layer 20 and a dye layer 30 in this order on the other surface of the substrate 10, wherein the undercoat layer 20 comprises: a copolymer between a polyester having a sulfonic acid group and an acryl having at least one of a glycidyl group and a carboxyl group; and a polyvinyl pyrrolidone and the undercoat layer 20 has a storage modulus G' at 100°C of 1.0E+06 N/mor more.SELECTED DRAWING: Figure 1 |
