摘要：<p>Dispersion adjuvants are described comprising beta -hydroxyalkyl esters of the formula <IMAGE> (I) wherein the R1 and R2 represent hydrogen or alkyl with 1 to 21 carbon atoms, in which at least one of R1 and R2 is alkyl and the sum of the carbon atoms in R1 and R2 ranges from 6 to 22, and wherein R3 represents alkyl with 1 to 8 carbon atoms, optionally substituted with 1 to 2 hydroxyl groups and/or interrupted by 1 to 2 ether bridges, as well as the adducts of compounds of Formula I with alkylene oxides, preferably ethylene oxide and/or propylene oxide. The dispersion adjuvants are coated on pigment and filler materials for paints and lacquers. The coating is applied before or during the dispersion of the materials in the paint or lacquer media or vehicle.</p>
