ABSTRACT:
A method for processing a silver halide color photographic material, which comprises processing an imagewise exposed silver halide color photographic material with a processing solution containing at least one chelate compound of a metal salt selected from the group consisting of salts of Fe(III), Mn(III), Co(III), Rh(II), Rh(III), Au(II), Au(III) and Ce(IV) with an organic acid represented by following general formula (I): ##STR1## wherein Z represents a nonmetallic atom group required to form a heterocyclic group; R represents a substituent; n represents 0 or an integer of from 1 to 10; Q.sub.1, Q.sub.2 and Q.sub.3 each represents a hydrogen atom, an aliphatic hydrocarbon group substituted by a carboxyl group, an aromatic hydrocarbon group substituted by a carboxyl group or a heterocyclic group substituted by a carboxyl group; and W represents a divalent linkage group containing at least one of an alkylene group or an arylene group.
