Photographic element containing imidazolonoylacetanilide coupler |
abstract |
Disclosed is a photographic element comprising a light sensitivensilver halide emulsion layer having associated therewith a coupler represented bynformula F-1 ,n nwherein:n R 1 , R 3 and R 5 are independently selected from hydrogen or a substituent groupnand two of them may join to form a ring; X is hydrogen or a coupling-off group; B is hydrogen or a substituent group; Z is a substituent group, and n varies from 0-4. nThe element exhibits improved dye-forming activity and an improvedncombination of dye hue and dye stability. |
