Abstract: There is provided a heat-sensitive transfer recording medium which is able to better suppress the occurrence of abnormal transfer during high-speed printing using a high-speed printer of sublimation transfer type and is able to improve transfer sensitivity in high-speed printing. The heat-sensitive transfer recording medium includes a base (10), a heat-resistant lubricating layer (20) formed on one surface of the base (10), an underlying layer (30) formed on the other surface of the base (10), and a dye layer (40) formed on a surface of the underlying layer (30), which is on the other side of a surface facing the base (10). In the heat-sensitive transfer recording medium, the underlying layer (30) has a major component that is a copolymer of polyester having a sulfonic group on a side chain and acrylic having at least one of a glycidyl group and a carboxyl group.

Abstract: A thermal transfer image receiving sheet including a substrate having a surface, a heat-insulating layer formed on the surface, an undercoat layer formed on the heat-insulating layer, and a dye-receiving layer formed on the undercoat layer. The undercoat layer includes as a main component a polycondensate made from i) at least one of an alkoxide, a hydrolyzate of an alkoxide, and tin chloride, ii) a water-soluble polymer, iii) a vinyl pyrrolidone-vinyl imidazole copolymer, and iv) a urethane resin.
