The present invention provides a coating composition containing 1) a carbamate-functional resin having in its structure a hyperbranched or star polyol core, a first chain extension based on a polycarboxylic acid or anbydride, a second chain extension based on an epoxy containing compound, and having carbamate functional groups on the core, the second chain extension, or both; and 2) a second resin containing functional groups reactive with the carbamate groups on the carbamate-functional resin. In one embodiment, the coating compositions are used as a cloarcoat to be applied over a basecoat to form a composite coating. The compositions exhibit a combination of desirable properties, such as scratch and mar resistance, resistance to environmental etch, good intercoat adhesion, and high solids.

The invention provides carbamate-functional resins and coating compositions incorporating said resins that have improved adhesion with respect to subsequently applied films or coatings. More particularly, the invention relates to carbamate-functional addition polymers having at least 250 grams of polymer per carbamate group which are made with less than 35 percent by weight of nonfunctional monomers, preferably with less than 20 percent by weight and most preferably from 0 to less than 10 percent by weight, based on the total weight of the polymer. The invention further provides a method of making a carbamate-functional polymer and carbamate-functional polymers made by the claimed method. Finally, the invention provides a method for improving the adhesion of a first coating composition to a subsequently applied material as well as a method of making a composite comprising a coated substrate, an adhesive composition, and a glass having at least one surface.

Clearcoat coating composition for automotive exterior coatings with improved intercoat adhesion to a subsequently applied coating layer and improved flexibility contains (a) a first vinyl copolymer prepared from a monomer mixture including no more than about 35% by weight of nonfunctional monomers that has carbamate functionality and hydroxyl functionality, at least part of the hydroxyl functionality being on monomer units including an optionally branched alkyl group having at least about six carbon atoms; (b) a second vinyl copolymer having hydroxyl functionality, preferably primary hydroxyl functionality; and (c) a curing agent component that includes at least an aminoplast curing agent and optionally a polyisocyanate curing agent. The polyisocyanate curing agent is preferably blocked with a blocking agent that volatilizes during the cure reaction, regenerating a reactive isocyanate group.
