Applies specifically to films with a base of safety cellulose ester or polyester Äpoly(ethylene terephthalate)Ü having silver-gelatin emulsions, processed to produce a black-and-white silver image by negative or full-reversal processing. The films that may have ultrasonic or dielectric (induction heated) splices are processed by a monobath which includes thiosulfate as the fixing agent followed by a conventional wash.
