    • 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 aryl group with 8 total carbon atoms or less; R is a carbonyl or sulfonyl group; and INH is an inhibitor of silver development. It has been found that such 2-substituted-5-amino-1-napthol based DIRs have improved properties and can provide a conventional silver halide photographic element with excellent image structure and color reproduction.
