    Abstract: The null-hydroxy carbamate, ethylenically unsaturated monomer of the invention can be polymerized as a homopolymer or copolymerized with other monomers. The polymerization can be carried out in an aqueous medium. The null-hydroxy carbamate monomer is polymerized to form water-soluble homopolymers or, if polymerized as a mixture with one or more comonomers, copolymers that are soluble, emulsifiable, or dispersible in water. The null-hydroxy carbamate monomer can be used as a replacement monomer for acrylamide.

    Abstract: The coating composition of the invention includes a polymer, especially an acrylic polymer, having hydroxyl and/or primary carbamate functionality; a water-miscible organic solvent; a low hydrogen bonding oxygenated solvent; and water that is emulsified in the organic phase. The coating composition of the invention may be a clearcoat coating composition, preferably an automotive clearcoat coating composition. The invention further provides an article, such as an automotive vehicle, having a surface coated with a coating derived from the coating composition of the invention, particularly a composite coating having a basecoat layer and a clearcoat layer, and a method of producing such a coating on a substrate, particularly as a basecoat/clearcoat composite coating, with the coating composition of the invention preferably being at least the clearcoat of the composite coating. The coating composition of the invention provides especially low volatile organic content, with significant reductions of 25% or more from comparable previous coating compositions.
