Refers to safety cellulose esterbase and safety polyester base films that have an ammonia processed diazo photographic image. Describes photographic diazo film intended for and used as medium term and long term storage copies and to photographic film in which the image layer is a discrete layer attached to a transparent support or in which the image forming chemicals are imbibed into a transparent support, and to motion picture, microfilm, roll and sheet film.
