Abstract
Abstract A color photographic silver halide light-sensitive material is described, containing at least one member of the compounds represented by the general formula (I-a) and (I-b) in at least one layer thereof: ##STR1## (wherein all the symbols are defined in the appended claims). This color light-sensitive material can be subjected to rapid photographic processing; i.e., the compounds of the general formula (I-a) and (I-b) act as bleach accelerators, making it possible to perform rapid photographic processing without exerting adverse influences on photographic characteristics.
