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. In a specific aspect, image-transfer film units and processes of forming image records in image-transfer film units are disclosed wherein an inert transition metal complex and a reducing agent, which undergo redox reaction in the presence of a catalytic material, are present during processing of said film unit.
