ABSTRACT:
An improvement is provided in processes wherein an oxidation-reduction reaction is utilized to form an image. In one aspect of this invention, the improvement comprises employing an oxidizing agent and a reducing agent which undergo imagewise redox reaction in the presence of catalytic material, the oxidizing agent and the reducing agent being so chosen that the reaction products are noncatalytic for the oxidation-reduction reaction. In another aspect of this invention, a substitution inert metal complex is utilized as the oxidant in oxidation-reduction, image-forming processes. Novel processing compositions and photographic materials are also described.
