摘要:
A thermal transfer printing method using a color developing layer transfer sheet having color developing layer at least on either side of its substrate, a dye layer transfer sheet having at least on either side of its substrate and an intermediate medium and including the steps of first transferring partly or entirely the color developing layers on the color developing layer transfer sheet onto the intermediate medium by means of heat and/or pressure as color developing layer transfer means, then laying the color developing layer and the dye layer one upon the other and causing the dye to migrate to the color developing layer on the intermediate medium by means of heat and pressure for formation of pictorial image thereon and further transferring the formed pictorial image from the intermediate medium onto the color receiving sheet again by means of heat and pressure.
