Diffusion transfer photosensitive film unit for silver transfer image

There is disclosed a photographic image including an ink-acceptable surface thereon. The photographic image may be formed by known conventional or diffusion transfer techniques. The ink-acceptable surface is formed by applying an aqueous mixture of a polymeric mordant material over the photograph and forming a relatively clear dry coating thereon. The subject coating provides an ink-acceptable surface upon the photograph which accepts and retains ink applied thereto and resist the remove of such ink therefrom.
