ABSTRACT:
A method of obtaining a photothermographic or thermographic film with reduced fog, such as pepper fog, comprises preparing a dispersion of: an oxidation-reduction image-forming combination comprising: a silver behenate oxidizing agent the improvement wherein said oxidizing agent contains less than about 800 micrograms of polyunsaturated and 3800 micrograms of monounsaturated fatty acid silver salts per gram of oxidizing agent or the film contains less than about 100 micrograms of polyunsaturated and 400 micrograms of monounsaturated fatty acid silver salts per gram of melt in the film and an organic reducing agent with a synthetic polymer-peptized photosensitive silver halide, and a cyclic imide toner in a non-gelatin polymeric binder.
