<p>Photographic elements are disclosed which comprise a support having thereon at least two image dye-providing layer units which each contain a silver halide emulsion and a color coupler. The silver halide emulsion of one of the image dye-providing layer units has a substantially larger mean grain size than the silver halide emulsion of at least one other image dye-providing layer unit and has associated therewith at least 10 mg./ft.2 of a nondiffusing anionic organic compound. The image dye-providing layer units containing a coarse-grain emulsion and the nondiffusible anionic organic compound exhibit high rates of silver formation when developed with a color-developing agent such as a p-phenylenediamine.</p> |
