Abstract: 1527009 Disazo pigments HOECHST AG 17 Dec 1976 [20 Dec 1975] 52818/76 Heading C4P Novel disazo pigments having the formula (where each K independently is the radical of a coupling component which does not contain watersolubilizing groups) are prepared by tetraazotizing 3,8-diamino-phenanthridone and coupling with 2 mols. of a coupling component, or a mixture of coupling components of formula K-H. The coupling is preferably carried out in the presence of a surfactant and organic solvent. The product is preferably heated in an aqueous, aqueous organic or organic medium at 100-200‹ C. to modify the physical form. The pigments are used in spin dyeing and also to colour printing inks, lacquers, dispersion paints, rubbers, plastics materials and natural or synthetic resins and paper.
