PURPOSE:To improve a sublimation speed and image stability, by forming heat sensitive transferring ink by making use of a coloring matter to be represented by a specific formula in the coloring matter for a color hard copy. CONSTITUTION:Heat sensitive transferring ink is constituted of a coloring matter represented by a specific formula, a binder such as a rosin, an organic solvent such as resin, methanol and/or water. In a formula. R1, R2 represent a hydrogen atom 1-4C alkyl group, alkoxy group and halogen atom, R3 represents a hydrogen atom and 1-4C alkyl group, R4-R6 represent the hydrogen atom a 1-6C alkyl group, 3-8C alkoxy alkyl group, 6-10C alkoxy alkoxy alkyl group, 3-7C alkyl carboxy alkyl group and 5-10C alkyl carboxy alkoxy alkyl group. The coloring matter manufactured by diazotizing, for example, aminobenzisothiazole and coupling with diaminopyridine is used. |
