PURPOSE:To maintain the photographic characteristic of the title material stable by compensating a compd. which is taken out from a developer by the photosensitive material, with the photosensitive material itself, in a running treatment. CONSTITUTION:An indazole compd., a benzimidazole compd. or a benzotriazole compd. which is shown by formula I and is blocked, is incorporated in the rear layer of a supporting body. In the formula, CA is a blocking group capable of releasing the indazole compd., the benzimidazole compd. or the benzotriazole compd., at the time of developing the photosensitive material, D is indazole compd., the benzimidazole compd. or the benzotriazole compd. which is bound to said compd. via a hetero atom. The photographic characteristic of the photosensitive material having good stability is obtd. by incorporating the precursor of the indazole compd., the benzimidazole compd. or the benzotriazole compd. which is taken out from the developer in the running treatment, in the rear layer of the supporting body of the photographic sensitive material. |
