Abstract
An exposed light-sensitive silver halide photographic material containing a coupler is processed with a developing bath and thereafter with an amplifying bath containing hydrogen peroxide, said process being characterized in that a compound acting on the silver halide at the unexposed portion of the photographic material is incorporated into the developing bath or into a bath used for a treatment effected after the development and before processing with the amplifying bath.

In a method for processing an imagewise exposed light-sensitive silver halide photographic material containing a coupler, which method comprises developing said silver halide photographic material with a developing bath for imagewise forming a catalytic silver and thereafter amplifying with an amplifying bath containing hydrogen peroxide, the improvement comprising treating, during said developing or after developing but before said amplifying, said exposed light-sensitive silver halide photographic material with a primary amine color developing agent and a compound capable of adsorbing on or dissolving silver halide at the exposed portion of the photographic material, thereby to effect deactivation of said unexposed silver halide, said compound being selected from the group consisting of mercapto compounds, azole compounds, oxonium compounds, silver halide solvents, benzyladenine, 8-hydroxyquinoline, o-phenanthroline, thiosugar and dyes.
