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 salt oxidizing agent and an organic reducing agent with: a synthetic polymer-peptized photosensitive silver halide, and a cyclic imide toner in a non-gelatin polymeric binder and mixing with said dispersion a sensitizing concentration of non-silver iodide salt formed from an ionic formate the improvement wherein said non-silver iodide salt contains less than about 100 micrograms of ionic formate per gram of iodide salt or the film contains less than about 0.5 micrograms of ionic formate per gram of emulsion in the film.
