PURPOSE:To obtain the title material having an improved color reproductivity and light durability, and to prevent a change of a photographic property of the title material due to a lapse of time after photographing by incorporating a specific pyrazoloazole type coupler and a specific aromatic compd., an amine compd. or a metallic complex to the title material. CONSTITUTION:The title material contains the pyrazoloazole type coupler shown by formula I wherein Xa and Zb are each =CH-, =CR2 of =N-, R1 is a hydrogen atom or substituent, R2 is a substituent, X is a hydrogen atom or a group capable of releasing with a coupling reaction of an oxidant of an aromatic primary amine developing agent, when Za=Zb group is a C-C double bond, it may be a part of an aromatic compd. one or more of R1 and R2 have one or more of -NHSO2- groups, the aromatic compd. shown by formula II (wherein R3 is a hydrogen or an alkyl group, etc., R4-R8 are each a hydrogen, an alkyl or an alkenyl group), and the amine compd. shown by formula III (wherein R9-R11 are each an alkyl or an alkenyl group etc. R12 is an alkyl group or a OH group etc., R13-R16 are each a hydrogen atom or an alkyl group, A is a non-metallic atom group capable of forming a 5-7 membered ring) or one or more of one kind of the metallic complex contg. a center metal such as Cu, Co, Ni and Pd, etc., and at least one of org. ligands having >=2 valents coordination. |
