ABSTRACT:
The present invention provides a curable coating composition that includes at least three components. The coating composition includes a component (a) that includes one or both of a compound (a)(1) having at least one carbamate group or terminal urea group according to the invention and having at least two linking groups that are urethane or urea or a compound (a)(2) having at least two groups selected from carbamate groups, terminal urea groups, or combinations of the two and at least four urethane or urea linking groups. The second component (b) of the coating composition includes a polymer resin comprising active hydrogen-containing functional groups reactive with the third component (c). The resins is selected from polyester, polyurethane, or polyester-polyurethane copolymers Component (c) of the coating composition is a curing agent that is reactive with the first two components. Preparation of coated articles using the compositions of the invention is also disclosed.
