ABSTRACT:
There are disclosed a processing solution having bleaching ability for use in light-sensitive silver halide photographic material, which comprises at least one selected from metal complexes of large cyclic polyamine derivatives and a method for processing of light-sensitive silver halide photographic material, which comprises carrying out development processing of an exposed light-sensitive silver halide photographic material and then processing the developed material with the processing solution.
The processing solution of the present invention has potent bleaching power, and can afford excellent photographic image characteristics by processing therewith.
