COATING COMPOSITION WITH TRISAMINE FUNCTIONALIZED DISPERSANT

摘要

The present invention relates to a composition comprising a stable aqueous dispersion of polymer particles and a dispersant adsorbed onto the surfaces of TiO2 particles, wherein the dispersant is a water-soluble polymer functionalized with structural units of a carboxylic acid ester and tris(hydroxymethyl)aminomethane. The composition of the present invention is particularly useful for achieving high hiding for paints containing associative thickeners.
