PURPOSE: To reduce changing in color quality due to density and improve light- resistance by providing, on a transfer sheet, a coloring material layer which contains coloring matters of disazo, dicyanoimidazole azo, indoaniline and nitrothiazole azo to be expressed by a formula. CONSTITUTION: On a transfer sheet, a coloring material layer which contains coloring matters to be expressed by a formula is provided. In the formula, X<1> -X<4> represent a hydrogen atom, an alkyl group, an alkoxy group, a hydroxyl, a nitro group, a cyano group, an acyl group, an acyl amino group, an alkoxy carbonyl group, an alkoxy carbonyl amino group, an alkyl sulfonyl group, a sulfamoyl group which may be substituted with alkyl, or a halogen atom, Y<1> -Y<6> represent a hydrogen atom, an alkyl group, an alkoxy group, a halogen atom or a hydroxyl, and Y<1> -Y<2> or Y<4> -Y<5> may be connected to each other so as to form an aromatic ring. Thus, recording can be done with highly black density which is almost colorless, changing in color quality due to density is small, and recording with black which shows a high light-resistance can be achieved. |
