Abstract: Aqueous suspensions of finely divided titanium dioxide are produced in the presence of dispersants by a process in which titanium dioxide powder and caprolactam are kneaded together in the dry state at from 15 DEG to 40 DEG C., the resulting mixture is kneaded with the addition of water, the paste thus obtained is suspended in water, the suspension is then allowed to sediment, and the resulting suspension containing finely divided titanium dioxide is decanted.

Abstract: Highly concentrated, low-dust preparations of disperse dyes containing a) at least one finely divided disperse dye, b) at least one surface-active agent obtained by reaction of amines of the formula H2N-(R-N)-H, in which R denotes C2- to C6-alkylene or phenylene, R denotes H or R denotes C1- to C4-alkyl and n denotes 1 to 5, with propylene oxide and then with ethylene oxide, the EO proportion being 20 to 60 % by weight and the reaction product having an average molecular weight of 4000 to 25000, c) if appropriate, a dispersant containing sulpho groups and d) if appropriate, further agents customary in such preparations. The preparations can be used for the dyeing and printing of PES and PES-containing blend fabrics.

Abstract: Highly concentrated, dust-free, solid and readily dispersible pigment formulations contain (a) from 70 to 95% by weight of one or more finely divided pigments, (b) from 5 to 30% by weight of one or more surfactants which possess 20-45% by weight of ethylene oxide units, have a mean molecular weight of from 4,000 to 15,000 and are obtained by reacting an amine of the formula where R is C2-C6-alkylene, R1 is H or C1-C4-alkyl and n is 1, 2, 3, 4 or 5, or R is 1,3-phenylene, 1,4-phenylene or 4,4'-diphenylenemethane, R1 is H and n is 1, with propylene oxide and then reacting the product with ethylene oxide, and (c) from 0 to 5% by weight of waxes and/or antifoams, with or without (d) other agents conventionally used in pigment formulations, the percentages being based on (a+b+c). The formulations are very useful for pigmenting aqueous, alcoholic or aqueous/alcoholic printing inks and surface coatings, and printing pastes for textiles.
