ABSTRACT:
Dry stabilization of a silver halide photographic material is obtained by heating the silver halide photographic material to a temperature of at least 80.degree.C. in the presence of an organic iodine-containing compound, such as monoiodoacetic acid, isopropyl iodide, or iodocyclohexane. Preferably, the heating is carried out after the formation of an image on the material. The organic iodine-containing compound can be added to the silver halide emulsion in the molten state during the preparation of the emulsion. This method is especially effective when applied to silver halide photographic materials which contain silver halide grains at least 50 mol% of which consists of silver bromide.
