Abstract
The present invention relates to a heat transfer sheet in which at least an ink layer is provided on a substrate. In the heat transfer sheet of the present invention, as an intermediate layer provided between the substrate and the ink layer contains an appropriate amount of particu+late material having the function of forming unevenness on the surface of the ink layer, without containing the particulate material in the ink layer, a 10-point mean surface roughness (Rz) of the surface of the ink layer can be 0.5˜5.0 &mgr;m. Namely, in accordance with the heat transfer sheet of the present invention, without a matte agent which may affect the image quality being used in the ink layer, the vacuum adhesion uniformity between the heat transfer sheet and an image receiving sheet at the time of heat-transfer can be ensured and an image with high quality can be formed.
