Abstract
Aqueous slurries of vesiculated cross-linked polyester resin granules which show a shrinkage of less than 5% on drying are prepared by a double-emulsion process in the presence of polyamine having a pKa value of 8.5-10.5 at a concentration of 0.3 to 1.4 amine groups per carboxyl group of the polyester, the acid value of which is limited to 10-45 mgm KOH per gm. The granules are of particular use as opacifying matting agents in latex paints and avoid the defect observed hitherto of cracking at high film builds.
