  • Photographic material with improved development inhibitor releases
    Patent number: 7175975
    Abstract: This invention relates to a multilayer silver halide photographic element, generally processed with phenylenediamine based developer solutions, comprising a support bearing a cyan dye image-forming unit comprised of at least one red-sensitive silver halide emulsion layer having associated therewith at least one cyan dye-forming coupler, a magenta dye image-forming unit comprising at least one green-sensitive silver halide emulsion layer having associated therewith at least one magenta dye-forming coupler, and a yellow dye image-forming unit comprising at least one blue-sensitive silver halide emulsion layer having associated therewith at least one yellow dye-forming coupler, wherein at least one layer additionally contains a 2-substituted-5-amino-1-napthol DIR according to Formula (I): wherein: X is chosen from among hydrogen, halogen atoms, an alkyl group with 6 carbon atoms or less or a N-substituted carbamoyl group where the N substituent is either an alkyl group with 6 carbon atoms or less or an ar
