Abstract

1,131,335. Processing photographic silver halide colour material. ILFORD Ltd. Aug. 23, 1967 [July 25, 1966], No.33381/66. Heading G2C. In the processing of an exposed photographic light-sensitive silver halide colour material by colour development followed by bleaching and fixing or by bleach-fixing, stain or colour fog is reduced or eliminated by treating the colour developed material before or during the bleaching step with an aqueous solution of N-hydroxymorpholine or N-amino-morpholine. The material may be washed between each successive treatment and the bleaching step may be preceded by an acid stop bath treatment. The compounds may be included in an acid stop bath, the bleach bath and/ or the bleach-fix bath.
