Abstract
Photographic elements are disclosed comprising a silver halide emulsion layer having associated therewith a dye forming coupler and a compound of the following Formula I: wherein n=0-6 and each R is independently hydrogen, an aromatic, cyclic, linear or branched chain hydrocarbon group, NR′R″, or OR′; where R′ is an aromatic, cyclic, linear or branched chain hydrocarbon group and R″ is hydrogen or an aromatic, cyclic, linear or branched chain hydrocarbon group. Photographic elements of the present invention upon exposure and photographic processing exhibit good activity and yield dye images that have unexpected and substantial improvements in the stability of the formed image dyes.
