PURPOSE:To maintain the stability of the green photosensitive material with age and to allow stable rapid continuous processing as well as to improve the picture stability after processing by incorporating a specific compd. and a specific org. color picture stabilizer in the photosensitive material. CONSTITUTION:The compd. expressed by the formula I is incorporated into one layer of photosensitive layers. The org. color picture stabilizer expressed by the formula D and an org. metal complex compd. are incorporated into the same or another photosensitive layer and the pyrazoloazole coupler expressed by the formula II is incorporated therein. In the formula, R<1>, R<2> respectively denote an alkyl, etc.; X denotes a combination group; R denotes a hydrogen atom or substituent; x denotes a group which can be eliminated by coupling reaction with a hydrogen atom, etc.; Za to Zc denote a methyne, etc.; R1, R2 respectively denote an aliphat. group, etc.; X denotes a group which is eliminated; A denotes a chemical bond group; (n) denotes 1 or 0; B denotes a hydrogen atom, etc.; Y denotes a group for acceleration. R denotes an aliphat. group, etc.; Z denotes a nucleophilic or group which releases the nucleophilic group; R30 denotes an aliphat. group, etc.; R31 denotes a hydrogen atom, etc.; W denotes -0-, etc. The color fading of the color pictures is decreased and the preservable stability is improved in this way. |
