Abstract
A heat transfer recording medium usable for producing an image by employing thermal printing means such as a thermal head, in which a dye layer of a heat transfer sheet or a dye-receiving layer of a heat transfer image-receiving sheet comprises therein or thereon a dye-transfer promoting agent comprising a compound which is in a crystalline state at room temperature and can be fused by thermal energy which is applied when heat transfer recording is conducted. A heat transfer recording method using a heat transfer sheet and an image-receiving sheet, in which a dye-transfer promoting agent comprising a compound which is in a crystalline state at room temperature and can be fused by thermal energy which is applied when heat transfer recording is conducted is given to a dye layer and/or a dye-receiving layer before the formation of an image.
