    Abstract: Pigment preparations useful for pigmenting or delustering finishes for leather and leather substitutes consist essentially of pigments or delusterants or a mixture thereof, binders, water and if desired further customary dispersants and auxiliaries, the binders used being copolymers of A) from 40 to 80% by weight of at least one aromatic vinyl compound of the general formula I (* CHEMICAL STRUCTURE *) I where R1, R2 and R3 are each hydrogen, methyl or ethyl and n is 1 or 2, B) from 20 to 60% by weight of acrylic acid or methacrylic acid or a mixture thereof, and C) from 0 to 10% by weight of further copolymerizable monomers, in the form of their salts.

    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.

    Abstract: A process for the preparation of stable dispersions of finely divided polyisocyanates, and the preparation of heat-crosslinkable isocyanate systems. Stable dispersions of finely divided polyisocyanates in a liquid which may or may not contain surfactants, protective colloids and other assistants are obtained by a method in which polyisocyanates are treated with a stabilizer in the presence of absence of the liquid, and the dispersions prepared from these are finely dispersed and/or milled under the action of high shear forces, if necessary with the addition of further stabilizer. These dispersions are useful as crosslinking agents, particularly for the preparation of heat-cross-linkable isocyanate systems.

    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.
