Abstract
A method for processing a color photographic light-sensitive material is disclosed. The process envolves providing an exposed silver halide color photographic light-sensitive material and subjecting the material to a color development processing. During the processing after development processing the material is brought into contact with a compound represented by the general formulae (I-a) or (I-b) in a bath of a bleaching or bleach-fixing processing or in a pre-bath thereof. ##STR1## wherein A represents an amino group which is optionally substituted or a nitrogen-containing hetero ring residue which may be optionally substituted, R.sup.1 represents a hydrogen atom or a carboxy group, R.sup.2 represents a monovalent metal atom, an ammonium group, an optionally substituted alkyl group or a group represented by ##STR2## R.sup.3 and R.sup.4 each represents a hydrogen atom or an alkyl group which may be substituted by a hydroxy group, an alkoxy group, a halogen atom, a carboxyl group, --SO.sub.2 H, --SO.sub.3 H, or a group represented by A described above, m represents 1 or 2, and n represents an integer of 2 to 4. The method of the 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.
