Abstract: In an image forming method in that an image-receiving layer of an image-receiving element is in contact with an ink sheet comprising a thermally transferable dye, and the dye is transferred to the image-receiving layer in accordance with imagewise-heating by a thermal head, the image-receiving layer having dye image formed by dye transfer is subjected to re-heating through a thin film material by thermal head.

Abstract: A thermal transfer recording method is disclosed. The process comprises a recording material comprising a support having thereon an ink layer containing a thermally diffusible chelatable dye and an image-receiving material comprising a support having thereon an image-receiving layer containing a compound having metal ions are superposed so that the ink layer of a recording material and the images-receiving layer of an image-receiving material are brought into contact with each other; the superposed recording material is heated imagewise employing a thermal head, whereby the thermally diffusible chelatable dye is transferred to the image-receiving layer to form an image; the image-receiving material having the image and a releasing agent-containing thin sheet material are brought into contact so that the image-receiving layer is brought into contact with the image-receiving layer; and the image-receiving material is heated through the thin sheet material.

Abstract: In an image forming method in that an image-receiving layer of an image-receiving element is in contact with an ink sheet comprising a thermally transferable dye, and the dye is transferred to the image-receiving layer in accordance with imagewise-heating, the image-receiving layer comprises a metal ion-containing compound and the ink sheet has repeatedly a region comprising both the metal ion-containing compound and a chelatable dye and a region comprising the metal ion-containing compound and no thermally transferable dye and the dye-containing region of the ink sheet is subjected to imagewise-heating, and to the image part formed on the image-receiving layer, the metal ion-containing compound is transferred by heating the region comprising the compound containing the metal ion. (2) In the above-mentioned (1), the image-receiving layer comprises substantially no metal ion-containing compound.
