Abstract: A thermal transfer recording medium that is able to better suppress bleeding or scumming of an image and better suppress the occurrence of peeling lines or abnormal transfer during thermal transfer. The thermal transfer recording medium according to an embodiment includes a heat-resistant slip layer that is formed on one surface of a base material, an undercoat layer that is formed on the other surface of the base material, and a dye layer that is formed on a surface of the undercoat layer that is opposite from the surface that faces the base material; wherein the dye layer includes at least a thermally transferable dye, a first binder resin and a release agent; the release agent includes polyether-modified silicone oil and a perfluoroalkyl compound, and the ratio of the polyether-modified silicone oil and perfluoroalkyl compound, on the basis of a weight ratio, is within the range 9:1 to 6:4.

Abstract: A thermal transfer recording medium that is capable of dealing with the requirement for an increase in thermal transfer printing speed, and high density and high quality of a thermally transferred image, capable of preventing the occurrence of abnormal transfer at high temperature and high humidity, and capable of improving transfer sensitivity in printing. A thermal transfer recording medium includes a heat-resistant lubricating layer on one surface of a base material, and an undercoat layer and a dye layer in that order on the other surface of the base material. The undercoat layer includes a copolymer of a polyester having a sulfonic acid group and an acrylic polymer having at least one of a glycidyl group and a carboxyl group, polyvinylpyrrolidone, and an oxazoline group-containing polymer. A binder resin of the dye layer is an acid-modified polyvinyl acetoacetal resin.
