SILVER COMPLEX DIFFUSION TRANSFER PROCESS

摘要

A method of stabilizing the image-tone of silver images formed according to the silver complex diffusion transfer process is described, which comprises either carrying out the diffusion transfer process in the presence of an aliphatic, aromatic or heterocyclic disulphide having at least one water-solubilizing group in acid or salt form or treating the image-receiving element subsequent to the formation therein of the silver complex diffusion transfer image with a solution of the said disulphide.
