Claims
- 1. A coating composition comprising a vinyl polymer having a monomer unit selected from the group consisting of
- 2. A coating composition comprising a carbamate or terminal urea functional vinyl polymer prepared by a process comprising
(a) reacting a compound having an hydroxyl group and a carbamate group, terminal urea group, or a group that can be converted to a carbamate or terminal urea group, with a cyclic carboxylic acid anhydride group to form a half-ester product with a free acid group; and (b) reacting the free acid group with an epoxide group, wherein either (1) one of the cyclic carboxylic acid anhydride group or the epoxide group is pendant to a vinyl polymer or (2) one of the compound having an hydroxyl group, a compound having the cyclic carboxylic acid anhydride group, and a compound having an epoxide group has polymerizable ethylenic unsaturation, said ethylenic unsaturation being polymerized, optionally with one or more copolymerizable monomers, to form a vinyl polymer after reaction of the compound in step (a) or step (b); and further wherein, when the compound having an hydroxyl group has a group that can be converted to a carbamate or terminal urea group, the group is converted to the carbamate or terminal urea group after step (a).
- 3. The coating composition of claim 2 further comprising a compound having carbamate functionality.
- 4. The coating composition of claim 2 further comprising a crosslinker reactive with active hydrogen groups.
- 5. A method comprising applying the coating composition of claim 4 to a substrate and curing the coating composition to form a coating.
- 6. The method of claim 5, wherein the coating is a clearcoat, and wherein the substrate has a basecoat layer that the coating composition is applied to.
