Abstract
Abstract A method for processing a color photographic light-sensitive material comprising subjecting an exposed silver halide color photographic light-sensitive material to color development processing then to bleach processing and fixing processing separately, wherein a bath of the bleach processing contains (a) at least one bleach accelerating agent selected from a compound having a mercapto group or a disulfide bond, a thiazolidine derivative and an isothiourea derivative and (b) at least one compound represented by the following general formula (I-a) or (I-b): wherein M represents a hydrogen atom, an alkali metal atom or an ammonium ion; R represents a hydrogen atom, a substituted or unsubstituted alkyl group, -S0 3 M 1 or -COOM'; R 1 represents -SO 3 M 1 or -COOM 1 ; M 1 represents a hydrogen atom, an alkali metal atom or an ammonium ion; and n represents an integer of 1 to 6 and when n is 2 or more, R's may be the same or different. According to the method of the present invention, color photographic images having good quality can be obtained without the formation of precipitate in a bleaching bath containing the bleach accelerating agent, even when color photographic light-sensitive materials are continuously processed.
