Abstract
A water-based latex of an acrylic-modified waterborne alkyd dispersion in water is described. The acrylic-modified waterborne alkyd is a hybrid resin prepared by the polymerization of at least one latent oxidatively-functional (LOF) acrylic monomer in the presence of a waterborne alkyd. Preparation of the latexes may be achieved by emulsion polymerization of at least one latent oxidatively-functional acrylic monomer in the presence of a waterborne alkyd whereby the latent oxidative functionality of the acrylic polymer survives polymerization. Such acrylic-modified waterborne alkyds are useful in a variety of coating compositions.
