Abstract
A photographic naphtholic coupler comprising a ballast free naphtholic coupler moiety containing a --CONH.sub.2 group in the 2- position and a ballasted coupling-off group in the 4- position enables good wash out of dye formed upon oxidative coupling from a photographic material during processing of such a photographic material. Such a naphtholic coupler is useful in photographic silver halide materials and processes.
Claims8
A photographic element comprising a support bearing at least one photographic silver halide emulsion layer and an immobile naphtholic coupler capable upon oxidative coupling of forming a dye that is capable of being washed out of the photographic element upon photographic processing, wherein the immobile naphtholic coupler comprises a ballast-free naphtholic coupler moiety comprising a --CONH.sub.2 group in the 2-position and in the 4-position a ballasted coupling-off group that comprises a releasable development inhibitor group.
