PURPOSE:To enable to rapid processing, and to obtain the titled bath suitable for work environment by controlling pH value of a processing solution to a range of 3.0-6.8, and by incorporating a ferric complex salt contg. a specific compd. as a ligant and a specific compd. to the titled bath. CONSTITUTION:The pH value of the processing solution which effects the bleach-fix of a silver halide photographic sensitive material for photographing lies in the range of 3.0-6.8. The titled bath contains the ferric complex salt contg. the compd. shown by formula I as the ligant, and the compd. shown by formula II. In formula I, R1 is hydrogen atom or a lower alkyl group, (n1)-(n3) are each an integer of 0-3. In formula II, R2 and R3 are each hydro gen atom, alkyl, acyl, or carbamoyl group, R4-R6 are each hydrogen atom or alkyl group, (m) is 0, 1 or 2. M is hydrogen atom or a cation. Thus, the titled bath is applied to the photosensitive material for the photographing, and enable rapid processing. As ammonia gas does not generate in the processing, the titled bath is preferable in the work environment. |
