ABSTRACT:
A method for processing a color photographic light-sensitive material comprising subjecting an imagewise exposed silver halide color photographic light-sensitive material to color development processing, then to processing with a bleaching solution and thereafter to separately, fixing processing wherein the silver halide color photographic light-sensitive material contains a cyan dye forming coupler represented by the general formula (I-a) or (I-b) described below, the bleaching solution contains a compound represented by the general formula (II-a) or (II-b) described below and the processing time for the bleaching solution is substantially not more than 2 minutes and 30 seconds, ##STR1## wherein R.sup.1, R.sup.2 and R.sup.4 each represents a substituted or unsubstituted aliphatic group, a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group; R.sup.3 and R.sup.6 each represents a hydrogen atom, a halogen atom, a substituted or unsubstituted aliphatic group, a substituted or unsubstituted aryl group or an acylamino group, or R.sup.3 represents a non-metallic atomic group necessary to form a nitrogen-containing 5-membered or 6-membered ring together with R.sup.2, R.sup.5 presents a substituted or unsubstituted alkyl group; Z.sup.1 and Z.sup.2 each represents a hydrogen atom or a group capable of being released upon the oxidative coupling reaction with a developing agent; and n represents 0 or 1, ##STR2## wherein R.sup.7, R.sup.8, R.sup.9 and R.sup.10, which may be the same or different, each represents a hydrogen atom, a substituted or unsubstituted lower alkyl group or an acyl group, or R.sup.7, R.sup.8, R.sup.9 and R.sup.10 may connect to each other to form a ring; and m and each represents an integer of 1 to 3.
