摘要 A photographic processing composition for processing a silver halide photographic light-sensitive material which provides an excellent desilvering prperty, improved bleaching fog and suppressed staining after processing. The composition contains at least one monoamine compound represented by formula (I) or salt thereof: <CHEM> where L represents an arylene group or a divalent heterocyclic group; L1, L2, L3, L4 and L5 each represents a divalent aliphatic group, a divalent aromatic group, or a divalent linkage group comprising a combination of these groups; A1, A2 and A3 each represents a carboxy group, a sulfo group, or a hydroxy group; Z represents an oxygen atom or a sulfur atom; k, t, m and n each represents 0 or 1; provided that when L is an arylene group to which a residue containing a -N(L1-A1)(L2-A2) group and a residue containing a -A3 group are bonded at a position ortho to each other, and k and n are 1, Z is not an oxygen atom and that when L is an arylene or divalent heterocyclic group to which a residue containing a -N(L1-A1)(L2-A2) group and a residue containing -A3 are bonded at a position ortho to each other, and k is 0, A3 is not a hydroxy group.
