<p>A thermal transfer sheet comprises a substrate sheet (1), a release layer (3) formed on one surface of the substrate sheet, a colouring layer (2) formed on the release layer and an adhesive layer (4) formed on the colouring layer. The release layer and the adhesive layer are formed from the same kind of material. Another thermal transfer sheet comprises a substrate sheet (6) and a heat fusible colouring ink layer (7) formed on one surface of the substrate sheet. An organic pigment of benzimidazolone-mono-azo is used as a colouring agent of yellow, a mixture of organic pigments of quinacridone-mono-azo and benzimidazolone-mono-azo is used as a colouring agent of magenta, and an organic pigment of phthalocyanine is used as a colouring agent of cyan, in the heat fusible colouring ink layer. <IMAGE></p> |
