PURPOSE:To improve both durability and preservation stability of coloring matter which is excellent in sublimation by a method wherein one or more kinds of each color to be expressed by two kinds of specific general formulas are contained to construct an yellow thermal sublimate transfer sheet for a thermal sublimate transfer system. CONSTITUTION:For a thermal sublimate transfer system, a thermal transfer sheet to which ink containing coloring matter for thermal sublimate transfer is applied, is superimposed on image receiving paper, and they are heated and fixed by pressure with a thermal head. Thereby, the coloring matter is sublimated to be transferred to the image receiving paper, and a good gradation colorful copy is obtained. In this case, respective coloring matter to be represented by two kinds of specific general formulas (1), (2) as given in the figure are contained respectively by not less than one kinds as an yellow thermal sublimate transfer sheet to be used in the abovementioned system. Then, in the general formula (1), Ar expresses a phenyl radical which may have a substituent, and R expresses an alkyl radical which may have a substituent. Further, in the general formula (2), X1-Z3 express respectively a hydrogen atom, an alkyl radical or a halogen atom. |
