<P>PROBLEM TO BE SOLVED: To provide a thermal transfer sheet which responds to demands for a higher printing speed of thermal transfer and a higher density and quality of a thermal transfer image and which prevents abnormal transfer, wrinkling, etc. and improves transfer sensitivity in printing. <P>SOLUTION: In the thermal transfer sheet constituted by providing a heat-resistant sliding layer 4 on one side of a base 1 and by forming an adhesive layer 2 and a dye layer 3 sequentially on the other side of the base 1, the adhesive layer 2 contains a polyvinyl pyrrolidone resin. Therefore the transfer sensivity on the occasion of thermal transfer is sharply improved and the thermal transfer image of high density is obtained without impression of high energy. By mixing an adhesive component in the adhesive layer 2 in addition to the polyvinyl pyrrolidone resin, the adhesion between the dye layer 3 and the base 1 can be increased even when the base 1 not treated for adhesion is used, and thereby the abnormal transfer etc. can be prevented. <P>COPYRIGHT: (C)2004,JPO |
