    Abstract: Dispersions of pigments, disperse- or vat-dyestuffs, wherein the dispersing agent is formed either by co-condensation of a phenolic component, formaldehyde and an alkali metal sulfite or of a sulfonated phenolic component and formaldehyde. These dispersions are characterized in that the dispersing agent used shows an improved dispersing effect. Furthermore, they can also be used when being neutralized for the dispersing alkali sensitive dyestuffs and they show no tendency to soil the fabrics so that also clean shades may be dyed.

    Abstract: A PROCESS FOR THE WET GRINDING OF PIGMENTS WHICH COMPRISES EFFECTING THE GRINDING IN AN AQUEOUS MEDIUM CONTAINING 0.1-20 PERCENT OF A BASE SELECTED FROM THE GROUP OF WATER SOLUBLE ALKALI METAL-, ALKALI EARTH METAL- OR AMMONIUM COMPOUNDS. THE ADDITION OF BASES INPROVES THE TRANSMISSION OF GRINDING ENERGY TO THE MATERIAL BEING GROUND AND RESULTS IN THE PRODUCTION OF PURER PIGMENTS OF BETTER TINCTORIAL STRENGTH IN A RELATIVELY SHORT GRINDING TIMEFURTHERMORE, THE GRINDING PROCESS ACCORDING TO THE INVENTION IS CARRIED OUT IN A SIMPLE AND INEXPENSIVE WAY.

    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: A process for the preparation of pigment compositions, which comprises adding to the pigments an aqueous solution of an alkali metal silicate and a polyethylene dispersion and working up the mixture in a manner usual for pigments. The pigment compositions thus obtained are useful for coloring polyethylene films and sheets or for dyeing polyolefins in a spinning solution. The compositions show an excellent pigment distribution and tinctorial strength which is substantially better than those of compositions prepared without the addition of alkali metal silicates.

    Abstract: Non-ionic surfactants of formula (I) are new: (A is a cycloalkyl-, aralkyl- or aryl-modified rosin gp. or its ester with a polyhydric alcohol; X is -CH2CH2- and/or -CH2CH(CH3)-; n is 1-100; m is 1-5). (I) are surfactants for use as dispersants, wetting or emulsifying agents or dyeing aids, in plant protection and pest control prods., etc. They show improved dispersion behaviour in aq. media, and almost no foaming in spite of good wetting properties. They are easily bio-degradable and resistant to strong acids and alkalis under normal conditions of use. Aq. solns. are very pale to colourless.

    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.
