<P>PROBLEM TO BE SOLVED: To provide a heat-transfer sheet which corresponds to demands such as the increase of the printing speed of the heat-transfer, the increase of the density of the heat-transferred image, and the quality improvement, and suppresses especially the fusion with an image receiving sheet or an abnormal transfer. <P>SOLUTION: For this heat-transfer sheet, at least on one surface of a base material, an adhesive layer, and a dye layer are formed in this order. The adhesive layer contains a polyvinyl pyrrolidone resin, and at least one each which is respectively selected from the (A) group and (B) group. (A) group: A polyurethane resin and/or an acrylic polyol resin which have solubility to a solvent mixture of methyl ethyl ketone/isopropyl alcohol=1/1 (weight ratio), and in which the gelation does not occur even when being diluted to a state having the solid content of 5 wt%. (B) group: An isocyanate, block isocyanate and/or an aluminum chelating agent which have solubility to the solvent mixture of methyl ethyl ketone/isopropyl alcohol=1/1 (weight ratio), and in which the gelation does not occur even when being diluted to a state having the solid content of 5 wt%. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
