Tetrazolium C-oxy-betaine compounds as antifog agents for silver halide photographic emulsions

摘要

Tetrazolium C-oxy-betaine compounds are effective antifog agents for silver halide photographic emulsions when reactively associated therewith. Such compounds can be incorporated in the photographic element in reactive association with the silver halide emulsion or in a processing bath prior to or during development of emulsion layers.
