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, 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.

Abstract: An aqueous pigment dispersion which contains (a) pigment, (b) a water-soluble surfactant and water and a water-retaining agent in which (b) is a reaction product of an aliphatic or aromatic diamine or polyhydroxyl compound with from 3 to 50 moles of propylene oxide and from 2 to 70 moles of ethylene oxide per equivalent of reactive amino hydrogen or hydroxyl. The dispersions give bright and deep-shade emulsion paints or distempers containing cellulose ethers.

Abstract: Aqueous dye formulations contain 0.1-15 wt.% dye, of which 90-100 wt% is an anionic disazo dye, which is a 4,4'-bis(7-amino-1-hydroxy-3-sulpho-naphthyl-2-azo)-stilbene-2,2'-disu lphonate salt of formula (I), 1-40 wt.% carbon black and 0.1-15 wt.% polyethylene glycol (PEG); in which Kat = the equivalent of a metal or ammonium ion. Also claimed are inks containing the formulation, water and optionally water-miscible organic solvent and aqueous-alcoholic varnish colours or printing inks containing the formulation, water and 1-4 carbon alkanol(s).

Abstract: Solid pigment formulations containing from 70 to 97% by weight, based on the total weight of the formulation, of one or more pigments and also from 3 to 30% by weight, based on the total weight of the formulation, of at least one surfactant which is an adduct of ethylene oxide and optionally propylene oxide with ethylenediamine, the proportion of ethylene oxide being from 46 to 100% by weight, based on the total weight of ethylene oxide and propylene oxide in the adduct, and the adduct having an average molecular weight of from 5000 to 40,000, are useful for pigmenting printing ink and gloss paint compositions.
