PURPOSE:To obtain a bleach-fixing soln. enabling rapid processing without generating gaseous NH3 by keeping a bleach-fixing soln. for a silver halide photographic sensitive material at a specified pH and incorporating a specified ferric complex salt and a polymer having pyrrolidone ring units. CONSTITUTION:A bleach-fixing soln. for a silver halide photographic sensitive material for photographing is kept at 3.0-6.8 pH and a ferric complex salt having a compd. represented by formula as a ligand and a polymer having pyrrolidone ring units in the molecular structure are incorporated into the soln. In the formula, R1 is H or lower alkyl, each of n1-n3 is 0-3, (n1+n2+n3)=2-4 and the total number of C atoms is -(CH2)n1-(CHR1)n2-(CH2)n3- is <=3. When a fast sensitive material for photographing is processed with the bleach-fixing soln., defective recoloring is prevented and the precipitation of silver sulfide is suppressed. Bleach-fixing can be rapidly carried out, no gaseous ammonia is generated and working environment is improved. The soln. maintains satisfactory desilvering and recoloring properties and high shelf stability during storage and the bleach-fixing performance is not deteriorated. |
