    Abstract: WATER-INSOLUBLE MONOAZO DYESTUFFS OF THE GENERAL FORMULA

    1-R2,6-((2,5-DI(R2-O-),4-(R1-NH-SO2-)PHENYL)-N=N-CH(-CO-

    CH3)-CO-NH-)-1,2,3,4-TETRAHYDROQUINAZOLINE-2,4-DIONE

    WHEREIN R1 IS HYDROGEN, LOWER ALKYL, ARYL, ARALKYL OR CYCLOALKYL, WHICH MAY BE SUBSTITUTED BY LOWER ALKYL OR HALOGEN, R2 IS LOWER ALKYL, R3 IS HYDROGEN OR LOWER ALKYL AND A IS A BENZENE NUCLEUS SUBSTITUTED BY LOWER ALKYL, LOWER ALKOXY ON HALOGEN. SAID PIGMENTS CAN BE USED, FOR EXAMPLE, FOR DYEING OR PRINTING PLASTICS, CAOUTCHOUC, NATURAL AND SYNTHETIC RESINS TEXTILE FIBROUS MATERIALS OR PAPER. FUTHERMORE THEY CAN 12BE EMPLOYED FOR THE PREPARATION OF PRINTING INKS, LACQUERS AND DISPERSION PAINTS. THE NOVEL PIGMENTS POSSESS GOOD TO VERY GOOD FASTNESS PROPERTIES.

    Abstract: 1,216,356. Monoazo dyes. FARBWERKE HOECHST A.G. 25 Oct., 1968 [27 Oct., 1967; 2 Aug., 1968 (2)], No. 50687/68. Heading C4P. Novel water-insoluble dyestuffs of formula (wherein Y is -OCH 3 or -NHR where R is H or C 1-4 alkyl, and X is H, halo, Me, OMe or OEt), are prepared by coupling an appropriate diazotized 5-amino-isophthalic acid derivative with an appropriate 5-acetoacetylamino-benzimidazolinone. The dyes are yellow-coloured and may be used in the production of printing inks, coloured lacquers or dispersion paints and for the colouring of caoutchouc, plastics, natural or synthetic resins, fibrous textiles, paper, viscose rayon, cellulose ethers or esters, polyamides, polyurethanes, polyglycol terephthalates and polyacrylonitrile.
