Abstract
Stabilized photographic recording materials are described which comprise ammonium salts of inorganic acids or of organic acids and preferably those that contain polyhydroxyalkyl residues. Use of these stabilizing compounds in combination with recognized antifogging agents provides enhanced storage stability of coated photographic compositions.
