摘要:
Novel valuable, water-insoluble disazo pigments of the general formula 1 ##SPC1##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.The pigments may be used for other purposes, for example in a finely divided form for dyeing rayon of viscose or cellulose ethers or esters, polyamides, polyurethanes, polyglycolterephthalate or polyacrylonitriles in the spinning mass or for dyeing paper. The pigments may be processed well in the mentioned media. The dyeings have a good color intensity as well as good fastnesses to light and to migration and are resistant to the influence of heat and chemical products, above all solvents.

摘要:
Diaminophenyl ureas of the formula ##STR1## in which R is an inert substituent, are obtained from the corresponding dinitrophenyl urea by way of reduction, especially catalytic hydrogenation. Through a cyclization process, while splitting off ammonia, these ureas yield the corresponding aminobenzimidazolones, advantageously without an intermediate isolation of the diaminophenyl ureas.
