<P>PROBLEM TO BE SOLVED: To provide a thermal transfer sheet which has high transfer sensitivity in thermal transfer printing, can obtain a high-density print, high clarity of a thermal transfer image, and can make sufficiently satisfactory printed matter available. <P>SOLUTION: This thermal transfer sheet has a heat-resistant lubricity layer formed on one surface of a base material, an undercoating layer consisting of a colloidal inorganic pigment ultrafine particle, formed on the other surface of the base material, and a dye layer laminated in that order. The undercoating layer consisting of the colloidal inorganic pigment ultrafine particle can enhance the adhesive properties between the base material and the dye layer. In addition, when an image is thermally transferred in combination with a thermal transfer image receiving sheet, the abnormal transfer of the dye layer to the image receiving sheet does not occur. Further, since the undercoating layer is hardly stained by a dye from the dye layer, it is possible to prevent the dye from migrating to the undercoating layer from the dye layer during printing, and increase the transfer sensitivity in printing and enhance a print density by effectively diffusing the dye to the acceptance layer side of the image receiving sheet. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
