Abstract

Abstract A method for processing a silver halide photographic light-sensitive material comprising a support having thereon a light-sensitive silver halide emulsion layer having associated therewith a blocked photographic agent capable of releasing a photographically useful agent, which method comprises processing the photographic light-sensitive material in the presence of an oxime. According to this method for processing a silver halide photographic light-sensitive material, both stability of the photographic light-sensitive material during storage and release of a photographically useful agent during processing are achieved without undersirable side-reactions, and a high sensitivity/fog ratio is obtained.
