Photographic silver halide colour materials.

摘要

A photographic silver halide colour element which comprises an emulsion layer unit containing one or more silver halide emulsions sensitised to the same spectral region having adjacent each side of said emulsion layer unit a layer substantially free of active silver halide containing an image modifier which is a compound capable of imagewise releasing an image-modifying compound on silver halide development wherein at least one of said layers contains a dye image-forming coupler.
