Abstract: In a process for preparing organosilver carboxylates where an organic carboxylate aqueous solution is admixed with a water-soluble silver salt aqueous solution, a solvent which is difficultly soluble in water is present in the organic carboxylate aqueous solution. According to the process, organosilver carboxylates are obtained in the form of fine particles, which are useful for preparation of heat developable photographic materials.

Abstract: Dry stabilization of a silver halide photographic material, which comprises heating a silver halide photographic material containing silver halide grains at least 50 mol% of which consists of silver bromide to a temperature of at least 80.degree.C. in the presence of 0.1 to 33 mol%, based on the silver halide, of an onium compound having an iodine ion or an anion containing iodine, such as methyltriethylammonium iodide, N-methylpyridinium iodide, or trimethylsulfonium iodide. Preferably, the heating is carried out after the formation of an image on the photographic material.
