PURPOSE:To obtain the titled material having the excellent color reproducibility and the remarkably improved optical fastness of a mazenta colored image by incorporating a specific mazenta coupler and a specific mazenta colored image stabilizing agent to the titled material. CONSTITUTION:The material is composed of at least one of the couplers shown by formula (I) and at least one of the compds. shown by formula (XII). In the formulas, wherein Z is a non-metallic atom group, X is a hydrogen atom or a substituent, R is a hydrogen atom or a substituent, Z2 is a non-metallic atom group, R12 is an alkyl, an alkenyl, a cycloalkyl or an aryl group, R13 is a halogen atom, an alkyl, an alkenyl, a cycloalkyl, an aryl, an acyl, an acylamino, a carbomoyl, an amino, an alkoxycarbonyl, a sulfonyl or a sulfonamide group, (l) is an integer of 1-4, (m) is an integer of 0-5. The amount to be used of the mazenta colored image stabilizing agent shown by formula (XII) is preferable to be 5-300mol%, more preferable to be 10-200mol% on the basis of the mazenta coupler. |
