Patent ID: 7132476

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 said base coat, wherein said transparent top coat is deposited from a clear film-forming thermosetting composition comprising: (i) a copolymer composition comprising segments comprised of alternating residues derived from a donor monomer composition comprising one or more monomers selected from the group consisting of isobutylene, diisobutylene, dipentene, isoprenol, and an acceptor monomer composition comprising acrylic monomers, and monomers containing functional groups, wherein said copolymer composition is substantially free of transition metals, Lewis acids, maleate-type monomer residues, and fumarate-type monomer residues; and (ii) a crosslinking agent having at least two functional groups that are reactive with the functional groups of the copolymer in (i).
