Abstract
1394657 Processing photographic silver dyebleach materials CIBA-GEIGYAG 20 Feb 1973 [28 Feb 1972] 8288/73 Heading G2C Exposed silver dye-bleach materials are processed in (1) an alkaline silver halide developing bath containing a dye bleach catalyst, passed directly into (2) an acid dye-bleach bath containing a dye bleach catalyst and then processed in (3) a bleach-fixing bath, (4) a silver halide fixing bath and (5) a washing bath, the entire processing from entry into bath (1) to leaving bath (5) lasting at most 6 minutes; being effected at 20 degrees to 50C and the dwell time in the individual baths being at most 2 minutes. Bleach-fixing bath (3) may have a pH value of at most'4 and contain as oxidizing agent a nitro compound e.g. a nitrobenzenesulphonic acid and as fixer thiourea. At least one of the baths may be divided into two or more baths. Washing baths may be used between any of baths (2), (3) and (4).
