Abstract: Novel azo dye-providing compounds and photographic elements containing such compounds are described. The present compounds contain a carrier moiety which, as a function of oxidation under alkaline conditions, provides a substance having a mobility different than that of the starting compound.

Abstract: A process for amplifying an imagewise exposure of a silver halide photographic element comprises the steps of (a) developing the element to release spectral sensitizing dye from a release compound as a function of silver halide development; (b) adsorbing the spectral sensitizing dye to undeveloped silver halide grains; (c) exposing the element overall to radiation absorbable by released spectral sensitizing dye to render developable silver halide grains to which the released spectral sensitizing dye has been adsorbed and (d) developing silver halide grains.
