Abstract: Provided is a thermal transfer sheet capable of forming an image having excellent glossiness, and having no printing wrinkle or having a lesser possibility of generating wrinkles. A thermal transfer sheet in which a dyestuff layer or a transcriptive protective layer is formed on one surface of a substrate and a back face layer is formed on another surface of the substrate, wherein the back face layer contains (A) a resin of which weight-average molecular weight (Mw) is more than 15,000; (B) a resin of which weight-average molecular weight (Mw) is not more than 15,000; and (C) a lubricant ingredient; and wherein the (B) resin is contained at an amount range of 3% by weight to 40% by weight on the basis of the total solid content weight of the back face layer.

Abstract: There is provided a thermal transfer sheet that includes a heat-resistant slipping layer and a colorant layer, the heat-resistant slipping layer and the colorant layer being formable in an in-line process, has excellent heat resistance, and can suppress tailing. The thermal transfer sheet includes a substrate, a colorant layer provided on one surface of the substrate, and a heat-resistant slipping layer provided on the surface of the substrate opposite to the colorant layer, wherein the heat-resistant slipping layer contains at least a binder resin containing an amino group-containing acrylic resin and an epoxysilane, and a slipping agent.

Abstract: The present invention provides a thermal transfer sheet that has good heat resistance and slip property, and prevents the occurrence of tailing upon printing to achieve good printing even in high-speed printing. A thermal transfer sheet including: a base material; a color material layer on one surface of the base material; and a heat resistant slipping layer on the other surface of the base material, wherein the heat resistant slipping layer includes a polyamide resin, a silicone-modified polyamide resin, and an ethoxylated alcohol-modified wax.
