    Abstract: A coating composition containing an emulsion polymer prepared with up to about 20% by weight, based on total polymerizable monomers, of addition polymerizable esters of the glycidyl esters of tertiary acids having 9 or more carbon atoms, preferably up to 18 carbon atoms, and particularly having 9 to 11 carbon atoms has improved application properties and produces coatings with better appearance and less water sensitivity. The emulsion polymerization process of the invention produces less coagulum without having to increase the amount of surfactant.

    Abstract: Coating compositions contain hydroxyl- or carbamate functional resins with a relatively low equivalent weight. The resins are based on a polyol core containing urea and hydroxyl groups, and made by reacting a polyisocyanate, preferably a triisocyanate, with an amino functional polyol, preferably a polyol having one amino group and two or more hydroxyl groups. The polyol core may be further extended to a first or higher generation dendrimer or hyperbranched structure by reacting the initial polyol core with a compound having one carboxyl group and two or more hydroxyl groups.

    Abstract: The invention provides a thermosetting aqueous primer composition that includes a dispersed polyurethane polymer, an acrylic polymer emulsion polymerized in the presence of the polyurethane dispersion, and a crosslinking component that is reactive with at least one of the polyurethane polymer and the acrylic polymer. The polyurethane polymer has a glass transition temperature of O DEG C or less. The acrylic polymer has a glass transition temperature that is at least about 20 DEG C higher than the glass transition temperature of polyurethane resin. The invention further provides a composite coating having as a primer layer a cured layer of the primer composition of the invention and having at least one topcoat layer.
