Abstract
Abstract The dye receiving sheet according to the present invention is a sheet to be used in combination with a heat transfer sheet provided with a dye layer, and comprises a receiving layer (3) for receiving the dye migrating from the above heat transfer sheet during heating printing formed on at least one surface of a sheet substrate (2). A specific feature of the dye receiving sheet according to the present invention is that the above receiving layer (3) comprises a specific modified polyester resin, namely, a phenyl group modified polyester resin and/or a long chain methylene group modified polyester resin, and by constituting the receiving layer (3) of such a resin, the dyeability of the printed image can be improved, and further the light resistance (weathering resistance) of the image obtained can be improved.
