Claim:
A multi-component composite coating composition comprising: (a) a base coat deposited from a pigmented film-forming composition; and (b) a transparent top coat applied over the base coat, wherein either the base coat or the transparent top coat or both is deposited from the thermosetting composition comprising a co-reactable solid, particulate mixture of: (c) a film forming material comprising functional groups; and (d) a crosslinking agent having at least two functional groups that are reactive with the functional groups in the film forming material (c) comprising a copolymer composition comprising at least 30 mol % of residues having the following alternating structural units: —[DM—AM]— wherein DM represents a residue from a donor monomer selected from the group consisting of isobutylene, diisobutylene, dipentene, isoprene, isoprenol, 1-octene, and mixtures thereof; and AM represents a residue from one or more acrylic acceptor monomers.
