PURPOSE:To enhance the thermal fastness of a transfer image by adding a specific dye to the color material layer on a support. CONSTITUTION:A color material layer contains a dye represented by formula I (wherein R1 is an acyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a heteryloxycarbonyl group, an aminocarbonyl group or a sulfonyl group, R2 is a hydrogen atom or an alkyl group, R3-R9 are a hydrogen atom, an alkyl group, an alkoxy group, a halogen atom, an acylamino group, an alkoxycarbonyl group, a cyano group, an alkoxycarbonylamino group, an aiinocarbonylamino group, a sulfonylamino group, a carbamoyl group or a sulfamoyl group, R4 is a 2-6C alkyl group, R10 and R11 are a hydrogen atom, an alkyl group or an aryl group and R8 and R11 and/or R10 and R11 and/or R7 and R10 may be mutually bonded to form a ring). |
