    Abstract: NEW 5 - (AMINOBENZENESULFONYLAMINO) - BENZIMIDAZOLONES OF THE GENERAL FORMULA

    2-(O=),5-((NH2,X1,X2-PHENYL)-SO2-NH-),R-BENZIMIDAZOLINE

    IN WHICH X1 AND X2 ARE EQUAL OR DIFFERENT AND REPRESENT A HYDROGEN ATOM, A LOWER ALKYL OR ALKOXY GROUP HAVING 1-4 CARBON ATOMS OR A HALOGEN ATOM, PREFERABLY A CHLORINE OR BROMINE ATOM, AND R REPRESENTS A HYDROGEN OR HALOGEN ATOM, PREFERABLY, A CHLORINE OR BROMINE ATOM, A METHYL, ETHYL, METHOXY OR ETHOXY GROUP. THEY MAY BE PREPARED BY REACTING BENZENESULFOCHLORIDES OF THE GENERAL FORMULA

    (A,X1,X2-PHENYL)-SO2-CL

    WITH 5-AMINO-BENZIMIDAZOLONES OF THE GENERAL FORMULA

    2-(O=),5-NH2,R-BENZIMIDAZOLINE

    IN WHICH FORMULAE A REPRESENTS A NITRO OR ACETYLAMINO GROUP AND X1, X2 AND R ARE DEFINED AS ABOVE, AND HYDROLYSING THE ACETYL GROUP IN THE PRODUCTS THUS OBTAINED OR REDUCING THE NITRO GROUP TO THE AMINO GROUP. THESE 5 - (AMINOBENZENESULFONYLAMINO) - BENZIMIDAZOLONES CAN BE COUPLED IN THEIR DIAZOTIZED FORM WITH N-ACETOACETYLAMINO COMPOUNDS OF THE BENZENE-, DIPHENYLAND BENZIMIDAZOLONE SERIES TO MONO AND DISAZO PIGMENTS WHICH ARE DISTINGUISHED BY EXCELLENT PROPERTIES OF FASTNESS AND VERY PURE AND BRILLIANT SHADES.

    Abstract: THE PRESENT INVENTION RELATES TO NOVEL WATER-INSOLUBLE MONO- AND DISAZO DYESTUFFS OF THE GENERAL FORMULA

    (5-(-NH-CO-CH(-CO-CH3)-N=N-(X1,X2-PHENYLENE)-SO2-NH-),R-

    BENZIMIDAZOL-2-ONE)N A

    WHEREIN X1 AND X2 MAY BE IDENTICAL OR DIFFERENT AND REPRESENT A HYDROGEN ATOM, A LOWER ALKYL OR ALKOXY GROUP HAVING PREFERABLY 1 TO 4 CARBON ATOMS, OR A HALOGEN ATOM PERFERABLY A CHLORINE OR BROMINE ATOM, AND R IS A HYDROGEN OR HALOGEN ATOM, METHOXY OR ETHOXY GROUP, N REPATOM, A METHYL, ETHYL, METHOXY OR ETHOXY GROUP, N REPRESENTS THE NUMBERS 1 OR 2 AND A AN OPTIONALLY SUBSTITUTED RADICAL, PREFERABLY OF THE BENZENE, NAPHTHALENE OR BENZIMIDAZOLONE SERIES OF N=1, AND OF THE BENZENE OR DIPHENYL SERIES IF N=2. THESE DYESTUFFS MAY BE USED FOR DYEING OR PRINTING LACQUERS, POLYMERS OR TEXTILE MATERIALS, THEY SHOW A GOOD FASTNESS TO LIGHT, TO WEATHER AND TO MIGRATION. FURTHERMORE, THEY ARE FAST TO HEAT, HAVE A HIGH TINCORIAL STRENGTH TO THE INFLUENCE OF CHEMICAL PRODUCTS, ESPECIALLY SOLVENTS, ACIDS AND ALKALIS.
