ABSTRACT:
A method for processing a color photographic light-sensitive material by subjecting an exposed silver halide color photographic light-sensitive material to color development processing then to bleaching processing and fixing processing or to bleach-fixing processing, which process comprises using a ferric ion complex salt or a persulfate as a bleaching agent in the bleaching processing or bleach-fixing processing and incorporating a compound represented by the general formula (I) described below or a salt thereof in a bath of the bleaching processing or bleach-fixing processing or in a pre-bath thereof. ##STR1## wherein R.sup.1 and R.sup.2, which may be the same or different, each represents a hydrogen atom or a lower alkyl group; X represents a --NH.sup.3 R.sup.4 group, a --COOM group, a --SO.sub.3 M group or a hydroxy group; R.sup.3 and R.sup.4, which may be the same or different, each represents a hydrogen atom or a substituted or unsubstituted alkyl group or R.sup.3 and R.sup.4 are bonded to each other to form a ring; M represents a cation; and n represents an integer of 1 to 5.
The method of the present invention does not produce poisonous materials which are harmful to the environment and provides an excellent high speed bleaching process without harming other photographic properties.
