ABSTRACT:
A photographic silver halide material and process comprises at least one image dye-forming coupler and at least one coupler (A) represented by the formula SOL-COUP-LINK-PUG wherein SOL is a water solubilizing amide group, COUP is a naphtholic coupler moiety that, upon reaction with oxidized developer is capable of releasing LINK-PUG and capable of forming a compound that is washed out of the photographic material during photographic processing; LINK-PUG is in turn capable of releasing a photographically useful group (PUG) during photographic processing; and wherein LINK is a carbamate linking group comprising a photographic ballast group on the nitrogen atom of the carbamate group. Such a photographic silver halide material enables formation of improved images.
