Abstract: Novel valuable, water-insoluble disazo pigments of the general formula 1 WHEREIN R is hydrogen, methyl, methoxy or halogen, preferably chlorine or bromine, and X also represents hydrogen or halogen, preferably chlorine. The disazo compounds are obtained by bisdiazotizing a 2,7-diaminodiphenylenesulfone and coupling it on an acetoacetylbenzimidazolone. These pigments are suitable for preparing printing inks, color lakes and dispersion paints, for dyeing rubber, plastics and natural or synthetic resins. Furthermore, they are suitable for the printing of pigments on substrates, especially textile fibre materials or other flat articles such as paper.
