PURPOSE:To enable rapid bleach-fixing in good working environment without generating gaseous NH3 by keeping a bleach-fixing soln. for a silver halide photographic sensitive material at a specified pH and incorporating two kinds of specified ferric complex salts into the soln. 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 I as a ligand and a ferric complex salt having at least one kind of compd. represented by one of formulae II-V as a ligand are incorporated into the soln. In the formula I, 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-(CHR2)n2-(CH2)n3)- is >=3. In the formulae II-V, R2 is 1-5C alkyl or the like, each of n4-n6 is 1 or 2, each of n7 and n9 is 0-9, each of n8-n10 is 1-3, (n7+n8+n9)>2, each of R3 and R4 is H, OH-substd. 1-3C alkyl or the like, each of R5 and R6 is H or OH-substd. phenyl, each of R7-R10 is H or OH-substd. 1-3C alkyl, R7-1010 may form 5-8C-membered rings, n12 is 0-4 and n13 is 1-8. The bleach-fixing soln. enables rapid bleach-fixing and has high shelf stability. |
