Abstract
In a dispersion containing acrylic polymer microparticles, particularly useful in automotive coatings, the dispersion is formed by free radical addition copolymerization of unsaturated monomers in a hydrocarbon dispersing medium in the presence of first and second polymeric dispersion stabilizers. The first polymeric dispersion stabilizer has an acrylic backbone and polyester side chains, and the second polymeric dispersion stabilizer is a branched polyester formed from the reaction of polyol, polyacid or anhydride, and fatty acid.
