Abstract
Disazo pigments are prepared by mixing an acid solution of a diazonium compound with an aqueous alkaline solution of a bis-[2-hydroxynaphthoyl-(3)]-arylenediamine in continuous manner with vigorous agitation, the resulting pigment suspension being continuously withdrawn. In particular coupling components of formula in which R is phenylene or diphenylene and which may be substituted by one or more halogen atoms, alkyl or alkoxy groups and X is halogen or hydrogen or an alkoxy group are used. Preferably, the liquids are mixed in a mixing nozzle and the coupling component may be dissolved with the aid of a solution promoter which may be a water-miscible organic solvent, e.g. alcohols, ethers, bases. The pigments produced are advantageously purified by treating with an organic solvent, e.g. chloronitrobenzenes, pyridine, picoline and quinoline.
