PROBLEM TO BE SOLVED: To provide a heat-sensitive transfer material which is excellent in fastness, especially in light-resistance by forming a layer containing at least a coloring matter of a specified structure on a supporting body. SOLUTION: For this heat-sensitive transfer material, a layer which contains at least a coloring matter represented by a formula is formed on a supporting body. In the formula, A indicates an atomic group which constitutes a six- membered heterocycle having -NRR as a substitutional group, and bonds with D by carbon atom in the ring represented by A. B indicates a coupler component, and bonds with D by an active site of the coupler component. D indicates nitrogen atom or CH. R1 , R2 respectively independently indicate hydrogen atom, an alkyl group which may have a substitutional group, an aryl group which may have a substitutional group, and a hetero ring group which may have a substitutional group. R1 , R2 may form a ring by bonding with each other. G indicates hydrogen atom or an alkyl group which may have a substitutional group, and an aryl group which may have a substitutional group. By this method, the heat-sensitive transfer material becomes excellent in fastness, especially in light-resistance. |
