There is described a photographic system wherein development of an exposed photosensitive element is carried out in the presence of an acylpyridine-N-oxide compound.

Photographic system

There is described a multicolor diffusion transfer film unit having a plurality of different color image components, each of which includes a color-sensitive silver halide emulsion in association with a corresponding image dye-providing material and a first silver halide developer which takes part in photographic development to provide an imagewise pattern of diffusible image dye-forming material as a function of photoexposure. At least one of said color image components includes a second silver halide developer, or a precursor thereof, which is capable of developing silver halide indiscriminately and which is made available after photographic development in the color image component in which it is located is substantially completed.
