ABSTRACT:
Image transfer photographic elements, 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 without 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: ##STR1## wherein: (a) Ballast is an organic ballasting radical;
