Abstract
1348360 Colour development AGFAGEVAERT AG 8 June 1972 [12 June 1971] 26743/72 Heading G2C Silver is bleached from a colour image in the bleach or bleach-fix stage of a photographic process in the presence of a water-soluble oxime, which may be aliphatic, carbocyclic or heterocyclic. The oxime combines with oxidized residual colour developer to prevent reaction with colour coupler and formation of fog. 0.5-10 g/l of oxime may be present in the bleach bath. Alternatively, the oxime may be contained in a pre-bleach bath at a concentration of 5-50 g/l. The oxime may be employed together with a white coupler at a concentration of 1-5 g/l in the bleach bath. A bleach-fix bath may contain 100-200 g/l of sodium or ammonium thiosuolphate. The process may be high speed (carried out at elevated temperature without washing between development and bleaching). Various oximes are specified.
