Abstract
A thermal transfer sheet that can meet demands for increased printing speed in thermal transfer, increased density of thermally transferred images, and higher quality and, at the same time, particularly can suppress fusing to image receiving sheets and abnormal transfer. The thermal transfer sheet includes a base material, a heat resistant slip layer provided on one side of the base material, and an adhesive layer and a dye layer provided in that order on the other side of the base material, wherein the adhesive layer includes a specific polyvinylpyrrolidone resin.
