Abstract: MIXTURES OF MONOAZO DYESTUFFS OBTAINED BY COUPLING DIARZOTIZED ANILINE, WHICH MAY BE SUBSTITUTED BY LOWER ALKYL, LOWER ALKOXY, HALOGEN OR NITRO WITH A MIXTURE OF ONE OR TWO POLAR COUPLING COMPONENTS OF THE ACETOACETYLAMINO BENZENE, 1-ARYLPYRAZOLONE-(5) OR NAPTHOL SERIES CONTAINING 1 OR 2 CARBOXYLIC ACID, SULFONIC ACID, CARBOXAMINO OR SULFONAMIDO GROUPS AND ANOTHER MIXTURE CONSISTING OF ONE OR TWO UNPOLAR COUPLING COMPONENTS OF THE ACETOACETYLAMINOBENZENE, 1-ARYLPYRAZOLONE-(5) OR NAPHTHOL- SERIES WITHOUT ANY SOLUBILIZING GROUP. THE DYESTUFF MIXTURES SHOW IMPROVED REHOLOGICAL PROPERTIES AND AN IMPROVED TINCTORIAL STRENGTH. MOREOVER, THEY YIELD PURER SHADES AND HAVE AN INCREASED TRANSPARENCY.

Abstract: AN AQUEOUS SUSPENSION OF A PIGMENT IS HEATED WITH AN ARALKYL ALKYLENE AMINE OF THE FORMULA
R-(CH2)N-NH-((CH2)X-NH)YH
OR A SLAT THEREOF, WHEREIN R REPRESENTS A SUBSTITUTED OR UNSUBSTITUTED PHENYL, N IS AN INTEGER FROM 1 TO 10, X IS AN INTEGER FROM 2 TO 10 AND Y IS AN INTEGER FROM 1 TO 5. THE RESULTING PIGMENT COMPOSITIONS ARE PARTICULARLY SUITABLE FOR PREPARING PRINTING INKS WHICH HAVE THE ADVANTAGE OF BEING NON-BLOTTING WHEN PRINTED ON THIN AND INFERIOR PAPER. THE PIGMENT COMPOSITIONS ALSO HAVE EXCELLENT RHEOLOGICAL PROPERTIES AND TINCTORIAL STRENGTH.-

Abstract: 1388139 Azo pigment peparations HOECHST AG 1 May 1972 [3 May 1971] 20113/72 Headings C4P and C4A Azo pigment preparations are prepared by adding an amine of general formula or a salt thereof, in which formula R is an unsubstituted or substituted phenyl radical, n is an integer 1 to 10, x is an integer 2 to 10, y is an integer 1 to 5, to the azo pigment, or pigment components before, during or after coupling of the pigment. The amount of amine may be 1 to 100% calculated on the weight of the pigment, preferred amines being N-benzyl-propylene-diamine, N-#-phenethyl-propylene-diamine, and N - 4 - methylbenzyl - propylene - diamine. The radical R may be substituted by nitro, halogeno, alkoxy and alkyl substituents. The amine may be added to an aqueous suspension of the pigment or pigment components which may be heated optionally under pressure. Printing inks prepared with the amine treated pigments have good rheological properties.

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.
