Abstract: A PROCESS FOR PREPARING BENZOXAZOLONES-(2) AND BENZOTHIAZONES-(2) HAVING THE GENERAL FORMULA

O=C
WHEREIN R IS A HYDROGEN OR HALOEN ATOM, PREFERABLY A CHLORINE OR BROMINE ATOM, AN ALKYL GROUP HAVING 1 TO 3 CARBON ATOMS, PREFERABLY AMETHYL GROUP, AN ALKOXY GROUP HAVING 1 TO 3 CARBON ATOMS, PREFERABLY A METHYL GROUP AND X IS OXYGEN OR SULFUR. THE BENZOXAZOLONES-(2) OR THE BENOTHIAZOLONES-(2) THUS OBTAINED ARE VALUABLE INTERMEDIATES FOR PHARMACEUTICAL PRODUCTS, FOR EXAMPLE ANALGETICS, HYPNOTIC, ANTIPYRETICS AND ESPECIALLY FOR DYESTUFFS SUCH AS AZO DYESTUFFS.

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.
