ABSTRACT:
A method of forming color in a silver halide photographic element wherein the silver halide is sensitized with a dye involves reacting an oxidized developing agent with a phenol or naphthol cyan dye-forming coupler or an acylacetamide yellow dye-forming coupler in a sulfoxide coupler solvent. The sulfoxide solvent reduces sensitizer dye staining with the cyan or yellow dye-forming coupler in processed photographic materials (films and papers) due to retained sensitizing dye.
