摘要： The present invention provides a curable coating composition that includes at least three components. The coating composition includes a component (a) having at least one carbamate group or urea group and having a lactone or hydroxy carboxylic acid moiety. The second component (b) of the coating composition is the reaction product of a polyol having at least one branch point, i.e., carbon bonded to at least three other carbons, with a lactone or hydroxy carboxylic acid. The third component 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.
