Abstract
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.
