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 3.0W6.8 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 IIWV as a ligand are incorporated into the soln. In the formula I, R1 is H or lower alkyl, each of n1Wn3 is 0W3, (n1+n2+n3)=2W4 and the total number of C atoms is -(CH2)n1-(CHR2)n2-(CH2)n3)- is ≥3. In the formulae IIWV, R2 is 1W5C alkyl or the like, each of n4Wn6 is 1 or 2, each of n7 and n9 is 0W9, each of n8Wn10 is 1W3, (n7+n8+n9)>2, each of R3 and R4 is H, OH-substd. 1W3C alkyl or the like, each of R5 and R6 is H or OH-substd. phenyl, each of R7WR10 is H or OH-substd. 1W3C alkyl, R7W1010 may form 5W8C-membered rings, n12 is 0W4 and n13 is 1W8. The bleach-fixing soln. enables rapid bleach-fixing and has high shelf stability.
