Abstract: 1348509 Preparation of mixtures of monoazo dyes FARBWERKE HOECHST AG 19 April 1971 [14 March 1970] 24057/71 Heading C4P Mixtures of monoazo dyes are prepared by coupling 1 mol of a diazotized amine of formula D-NH 2 with 1 mol of a mixture consisting of (i) 99À5 to 80 mol per cent of (a) a non-polar coupling component H-A or (b) a mixture of two non-polar components H-A and H-B containing at least 5 mol per cent of each component, and (ii) 0À5 to 20 mol per cent of (c) a polar coupling component H-X, or (d) a mixture of two polar components H-X and H-Y containing at least 10 mol per cent of each component, in which formulae D is a phenyl radical substituted by up to three halogen atoms or NO 2 , C 1-4 alkyl or C 1-4 alkoxy groups, A and B are different and are radicals of the acetoacetylamino-benzene, 1-aryl-pyrazolone-(5) or naphthol series, X and Y are different and are as defined for A and B but contain 1 or 2 COOH, SO 3 H, CONH 2 or SO 2 NH 2 groups, with the proviso that H-X is not 2-naphthol-7- sulphonic acid. The products are pigments of improved stability and tinctorial strength and colour printing inks and lacquers in yellow, red and green shades.

Abstract: 1339068 Disazo pigment mixtures FARBWERKE HOECHST AG 19 April 1971 [14 March 1970] 24056/71 Heading C4P The invention comprises the mixtures of disazo dyes obtained by coupling tetrazotized 4,4 1 -diamino-3,3 1 -dichlorodiphenyl with a mixture of coupling components consisting of (a) 0À5 to 20 mol. per cent of components H-X or H-Y or mixtures thereof and (b) 99À5 to 80 mol. per cent of components H-A or H-B or mixtures thereof, wherein A, B, X and Y are acetoacetylaminoaryl or 1-aryl-5-pyrazolone radicals, X and Y containing 1 or 2 COOH or SO 3 H groups and A and B or X and Y are always different. The products are yellow pigments and are used to colour printing inks or varnishes and in the mass dyeing of synthetic polymers.
