Abstract
The dye transfer type thermal printing sheet and method for printing of this invention are a printing sheet comprising a transfer sheet in which a smooth heat-resistant layer composed of fine particles, a liquid lubricating material and a polymer is formed on one side of a substrate, and on the other side is formed a coloring material layer containing at least one sublimable dye, non-sublimable particles and a binder, a part of said non-sublimable particles jutting out from the reference surface of the sublimable dye layer; and an image-receiving sheet having, on a substrate for image-receiving sheet, a development layer composed of, at least, inorganic fine particles; a binder having dye-affinity and another binder immiscible with said binder; and a dye transfer type thermal method for printing which comprises placing the aforesaid coloring material layer and development layer of the above-mentioned printing sheet face to face with each other, heating the printing sheet selectively from the smooth heat-resistant layer side of the transfer sheet, and thereby forming an image on the image-receiving sheet. By the above-mentioned sheet and method, there can given stable running of tra…
