Pigment formulations containing(a) at least one finely divided pigment,(b) at least one copolymer obtainable by free radical polymerization of(.alpha..sub.1) C.sub.8 -C.sub.40 -monoolefins or(.alpha..sub.2) C.sub.8 -C.sub.40 -alkyl vinyl ethers or(.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(.beta.) monoethylenically unsaturated C.sub.4 -C.sub.12 -dicarboxylic acids or C.sub.4 -C.sub.12 -dicarboxylic anhydridesand 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(c) if required, further assistants conventionally used in pigment formulationsare used for the preparation of pastes, printing inks and coatings.
