Abstract: Mixtures of monoazo compounds which are obtainable by diazotizing 0.75 to 0.85 molar equivalent of 5-nitro-2-amino-anisol and 0.25 to 0.15 molar equivalent of 3-nitro-4-amino-anisol and coupling onto 2-acetoacetylamino-anisol are pigments of high tinctorial strength, transparency, gloss and fastness to light having good rheological properties.

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: Process for the aftertreatment of the azo pigment of the formula C.I. PIGMENT ORANGE 36 wherein the crude pigment obtained after coupling is heated to temperatures from 100 DEG to 150 DEG C. in dry or wet condition in a solvent which is water-immiscible or not indefinitely water-miscible and the pigment is isolated in known manner. The pigment aftertreated in this way shows substantially improved hiding power while the same pigment prepared in the usual way has poor hiding power and can not be used in stoving lacquers.
