<p><P>PROBLEM TO BE SOLVED: To provide a copolymer containing an isobutylene type monomer and used as a flow control additive. <P>SOLUTION: The curable, aqueous film-forming composition is provided that includes a polymeric binder comprising reactive functional groups, a crosslinking agent having at least two functional groups that are reactive with the functional groups of the polymeric binder, and a copolymer flow control agent comprising at least 30 mol% of residues containing alternating residues from a donor monomer and from an acceptor monomer. The copolymer contains at least 15 mol% of an isobutylene type donor monomer. The multi-component composite coating composition is also provided, comprising a base coat deposited from a pigmented film-forming composition and a transparent topcoat applied over the base coat. The topcoat is deposited from the film-forming composition described above. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
