ABSTRACT:
Image transfer photographic assemblages, processes, compositions and cover sheets are described which employ a manganous compound. After processing, the manganous compound is capable of diffusing to the silver halide emulsion layer and a redox dye-releaser associated therewith to inhibit further dye release. Post-process D.sub.min stability is thereby improved.
