The invention concerns a composition comprising as component (A): 10% to 97% by weight, based on the total weight of the composition, of one or more monocarboxylic esters of the general formula R1—CO—OR2, in which R1 is a saturated or unsaturated, branched or straight-chain, aliphatic group having 11 to 23 carbon atoms and R2 is a branched or straight-chain aliphatic group, a cycloaliphatic group or aromatic group having 1 to 13 carbon atoms, and the sum of the carbon atoms of the groups R1 and R2 is not more than 30, the monocarboxylic ester or esters possessing a boiling point of more than 250° C. under a standard pressure of 101.3 kPa, and as component (B): 3% to 90% by weight, based on the total weight of the composition, of one or more dispersants, the composition possessing a viscosity at 25° C. of less than 5000 mPas. The invention further concerns the use of the composition as a dispersion medium, millbases obtained from the composition, and the use of the millbases.
