Amplification process

摘要

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.
