PHOTOGRAPHIC SILVER DIFFUSION TRANSFER FILM UNIT CONTAINING AN INSOLUBLE NON-DIFFUSIBLE NOBLE METAL COMPLEX INCLUDING A HYDROLYZABLE LIGAND

摘要

A novel photographic film unit, preferably a diffusion transfer film unit adapted to provide silver images of enhanced image stability which comprises photosensitive silver halide, silver precipitating nuclei and a stabilizing compound consisting of a noble metal complexed with a ligand, said ligand being adapted to hydrolyze in aqueous alkali to provide a diffusible complex of said noble metal.
