Black-and-white photographic elements and processes

Photographic elements for providing black-and-white images contain a silver halide emulsion having associated therewith a non-diffusible resorcinol coupler and a color developing agent or a precursor of a color developing agent. The elements can be processed by simple alkaline activation. Since imag...

Zusammenfassung:Photographic elements for providing black-and-white images contain a silver halide emulsion having associated therewith a non-diffusible resorcinol coupler and a color developing agent or a precursor of a color developing agent. The elements can be processed by simple alkaline activation. Since image density is derived at least in part from the resorcinol coupler, lower silver halide coverages can be employed or the silver can be recovered, or both.
