Abstract: The invention concerns the use, as dispersants for aqueous pigment suspensions, of partially esterified copolymers obtained by the copolymerization of (a) at least one C4 to C28 olefin and (b) ethylenically unsaturated dicarboxylic acid anhydrides with 4 to 8 C-Atoms in the molar ratio of 1:0.5 to 1:2 and the subsequent partial esterification of the copolymer with reaction products of (A) C1 to C30 alcohols, C8 to C22 fatty acids, C1 to C12 alkylphenols or secondary C2 to C30 amines and (B) at least one C2 to C4 alkylene oxide or tetrahydrofuran in the molar ratio (A):(B) of 1:2 to 1:200, and hydrolysis of the anhydride groups in the copolymer to give carboxyl groups, the partial esterification of the copolymer being carried out to an extent such that 1 to 50 % of the carboxyl groups in the copolymer are esterified. The invention also concerns pigment suspensions containing such partially esterified copolymers.
