Abstract

1,032,024. Bleach-fix compositions. ILFORD Ltd. April 13, 1965 [April 16,1964],No. 15822/64. Heading G2C. A bleach-fix composition comprises a cupric complex of pyridine-2. 6-dicarboxylic acid, of amino-diacetic acid or of nitrilo tracetic acid, a water-soluble halide and ammonium or as alkali metal thiocyanate. Such compositions are particular useful for bleaching silver in layers containing indophenol dyes derived from α-naphthol type colour couplers.
