Abstract

Pigment formulations containing PA1 (a) at least one finely divided pigment, PA1 (b) at least one copolymer obtainable by free radical polymerization of PA2 (.alpha..sub.1) C.sub.8 -C.sub.40 -monoolefins or PA1 (.alpha..sub.2) C.sub.8 -C.sub.40 -alkyl vinyl ethers or PA1 (.alpha..sub.3) a mixture of C.sub.8 -C.sub.40 -alkyl vinyl ethers and up to 50 mol % of C.sub.8 -C.sub.40 -monoolefins with PA2 (.beta.) monoethylenically unsaturated C.sub.4 -C.sub.12 -dicarboxylic acids or C.sub.4 -C.sub.12 -dicarboxylic anhydrides PA2 and having a molecular weight of from 500 to 20,000 g/mol, some or all of whose carboxyl or anhydride groups may be reacted with ammnonia, amines, alcohols, amino- or hydroxycarboxylic acids or alkali metal or alkaline earth metal hydroxides, and PA2 (c) if required, further assistants conventionally used in pigment formulations are used for the preparation of pastes, printing inks and coatings.
