Thermal transfer sheet

摘要

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.

1. 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 comprises: (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; (C) a lubricant ingredient, and wherein (B) the resin of which weight-average molecular weight (Mw) is not more than 15,000 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, and (B) the resin of which weight-average molecular weight (Mw) is not more than 15,000 is one of cellulosic resin, polyvinyl butyral resin, and polyester resin.
