Non-photosensitive receptor material suited for producing black-and-white silver images and dye images and a process for the production of such images therewith

摘要

Receptor material adapted for use in a combined dye transfer and silver complex diffusion transfer process, comprising in order: (i) a support, (ii) a first hydrophilic colloid layer containing a cationic compound capable of mordanting an acid dye, and (iii) a transparent second hydrophilic colloid layer containing development nuclei for catalyzing the reduction therein of silver complex salts to silver and at least one organic compound having an anionic group linked to a carbon atom. The use of the receptor material for the production of a black-and-white silver image in combination with one or more dye images results in silver images of increased density.
