  • Patent number: 6329130
    Abstract: Disclosed is a photographic element comprising a light sensitive silver halide emulsion layer having associated therewith a yellow dye-forming coupler having formula I: wherein each A is independently a divalent group selected from the divalent groups consisting of aryl and —C(R1)(R2)—, in which each R1 and R2 is independently selected from the group consisting of hydrogen, alkyl, alkoxy, aryloxy, heterocyclic, and aryl groups, and one A can be joined to form a ring with another A or with R3, and m is from 2 to 6; R3 is selected from the group consisting of hydrogen, alkyl, heterocyclic, and aryl groups, provided that R3 may form a ring with A or is a group joined to R4 to form a heterocyclic five- or six-membered ring; R4 is selected from the group consisting of aryl, heterocyclic, and alkyl groups and may form a heterocyclic ring bonded to R3; Y is selected from the group consisting of —SO2—, —C(═O)—, —C(═O)NR9R10—, —C(&bo
