Abstract
Abstract Dye developers and processes for making said dye developers are disclosed, along with photographic compositions and photographic elements containing said dye developers wherein the dye developer comprises a silver halide developing moiety connected to an indophenol moiety. In one aspect, the light-absorption characteristics of dye developers comprising the indophenol moiety when incorporated in a photographic element can be shifted to provide for exposure of a photosensitive material without substantial absorption competition and then can be shifted by contact with an ''onium compound to provide a good image dye. In another aspect, photographic elements are disclosed which contain a photosensitive composition having associated therewith a shifted indophenol dye developer; preferably, the photographic elements are used in image transfer film units.
