Abstract
The present invention provides a thermal transfer printing method, an intermediate medium and a transfer medium therefor, which make it possible to obtain printed image having deep color and high light resistance without back diffusion of dye. The method of the present invention comprises: PA1 transferring each color image by a printing head from a transfer medium A onto an intermediate medium wherein said transfer medium A has at least one color ink block consisting of color ink layers each of which contains different color ink, said intermediate medium has image receiving layers, whereby each image receiving layer on the intermediate medium contains one color image, and PA1 transferring each color image receiving layer onto an imaging sheet from the intermediate medium, so that a same image receive portion of the imaging sheet contains the image receiving layers corresponding to one color ink block.
