ABSTRACT:
An improved photographic silver halide element comprises a support, and an emulsion layer unit containing one or more photographic silver halide emulsions sensitized to the same spectral region and, adjacent each side of the 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 the layers contains a dye image-forming coupler. Such a layer arrangement enables greater control of the emulsion layer's response to oxidized developer generated upon processing.
