Abstract
A method of making a polyester or alkyd resin composition containing acrylic microgels comprises preparing an aqueous microgel emulsion of an acrylic resin which is crosslinked with a multifunctional crosslinking agent. The water from the emulsion can be removed by coagulation and/or azeotropic distillation with an organic solvent in which the microgel is insoluble and which forms an azeotrope with water. The resulting dehydrated microgel can be incorporated into a polyester or alkyd resin. Alternatively, the acrylic microgel emulsion can be incorporated into a water reducible alkyd resin.
