Color sheet for thermal transfer

Abstract

Abstract PURPOSE:To provide a color sheet for thermal transfer better in the environmental resistance and the color reproducibility of images by providing a colorant layer containing a mixture of a basic sublimating dye and a dispersing sublimating dye and a binder on a support. CONSTITUTION:A thermal transfer color sheet is arranged to have a colorant layer containing a mixture of a basic sublimating dye (e.g. dyes of the formulas I , II and III) and a dispersing sublimating dye (e.g. dyes of formulas IV, V and VI) and a binder (e.g. polysulfone and polycarbonate) on a support (e.g. condenser paper and thin sheet paper). The use of the basic dye alone may cause a change in the color tone during the prolonged preservation of images while the use of the dispersing dye alone provides a drawback of varying in the resolution and color tone of images during the prolonged preservation. The mixed use of the basic sublimating dye and the dispersing sublimating dye produces a transfer color sheet better in the environmental resistance and color reproducibility of images.
