Abstract
In a sublimation transfer method wherein a heat-meltable ink layer containing a sublimation dye is melt-transferred to give a master having an image of the ink, and the sublimation dye in the ink image is heat-transferred to form a dyed image on a substrate, there is used a heat-melt transfer medium wherein a release layer comprising a wax-like substance as a major component is provided between a foundation and the ink layer, or an adhesive layer comprising a wax-like substance as a major component is provided on the ink layer, or both the release layer and the adhesive layer are provided. The releasability of the ink layer from the foundation and the adhesiveness of the ink layers with each other are good. The method is especially useful to form a full-color dyed image.
