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.

Abstract: 1376399 Reactive water-soluble mono-azo dyestuffs FARBWERKE HOECHST AG 29 Aug 1972 [26 Aug 1971] 39989/72 Heading C4P Novel dyestuffs of the formula wherein A is a phenyl, naphthyl, pyrazolyl or acetoacetylarylamide radical substituted by at least one water-solubilizing group and optionally by further substituents and X is a vinyl group or a group of the formula -CH 2 CH 2 Z in which Z is OH or an inorganic or organic radical that can be split off by an alkaline agent, or salts thereof, are prepared by diazotizing an appropriate 2-amino-8-(SO 2 X)-naphthalene and coupling with a compound AH in an aqueous medium. In the products X groups can be interconverted, e.g. -CH 2 CH 2 OH may be esterified to -CH 2 CH 2 OSO 3 H and this may be converted to -CH 2 CH 2 N(C 2 H 5 ) 2 , or to -CH=CH 2 which may in turn be converted to The novel dyestuffs may be used for the dyeing and printing of wool, silk, leather, synthetic polyamide fibres and native or regenerated cellulose fibres.
