Abstract of the Disclosure Image transfer photographic element, assemblages, processes and compositions are described which employ carbon black in an opaque layer and/or alkaline processing composition, the carbon black having a deactivating compound adsorbed thereto so that dye image-providing material can diffuse through the opaque layer and/or processing composition with- out any substantial adsorption thereof to the carbon black, the deactivating compound being incapable of releasing any dye moiety therefrom. In a preferred embodiment, the deactivating compound has the following formula: Image wherein: a) Ballast is an organic ballasting radical; b) Z is Image or is part of Y; c) G is OR1 or NHR2 wherein R1 is hydro- gen or a hydrolyzable moiety and R2 is hydrogen or a substituted or unsubstituted alkyl group of 1 to about 22 carbon atoms; d) Y represents the atoms necessary to complete a benzene nucleus, a naphthelene nucleus or a 5- to 7-membered heterocyclic ring; e) X is a moiety which is adsorbed to the carbon black and thus retards adsorption thereto of the dye image-providing material; f) J is a bivalent linking group which is non- cleavable by oxidation; and g) n is a positive integer of 1 to 2 and is 2 when G is OR1 or when R2 is hydrogen or an alkyl group of less than 8 carbon atoms. Post-processing image dye diffusion is thereby lessened.
