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.
