  • Patent number: 7183355
    Abstract: A curable, aqueous film-forming composition is provided, comprising: (a) a copolymer containing reactive functional groups and comprising at least 30 mol % of residues having alternating structural units: -[DM-AM]- wherein DM represents a residue from a donor monomer, and AM represents a residue from an acceptor monomer, at least 15 mol % of the copolymer comprising a donor monomer having the structure (I): wherein R1 is linear or branched C1 to C4 alkyl, R2 is selected from methyl, linear, cyclic or branched C1 to C20 alkyl, alkenyl, aryl, alkaryl and aralkyl; and (b) a curing agent having functional groups reactive with the reactive functional groups of (a). The invention is also directed to a multi-component composite coating composition including a base coat deposited from a pigmented film-forming composition and a transparent topcoat applied over the base coat. At least one-coat is the film-forming composition described above.

  • Patent number: 7101930
    Abstract: A 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. Components (a) and (b) are substantially hydrophobic and are prepared as an aqueous dispersion comprising polymeric microparticles, prepared by mixing components (a) and (b) together under high shear conditions. A 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.

  • Patent number: 6387997
    Abstract: An aqueous dispersion including polymeric microparticles which are prepared in a medium substantially free of organic solvent from a mixture of one or more reaction products of polymerizable, ethylenically unsaturated monomers, and one or more reactive organopolysiloxanes is provided. Pigmented film-forming compositions, curable compositions and topcoats of multi-component composite coating composition containing the above-described dispersions also are provided. The substantially solvent-free film-forming compositions of the invention are storage stable at room temperature and provide coatings with excellent application properties such as sag resistance and tack-free overspray, and excellent performance properties such as hardness and scratch resistance. The film-forming compositions are suitable for wet-on-wet application over a base coat with little or no mudcracking.

  • Patent number: 6329060
    Abstract: A multi-component composite coating composition is provided which includes a pigmented base coat and a transparent topcoat composition applied over the base coat. The transparent topcoat is deposited from a substantially solvent free film-forming composition which includes a thermosettable dispersion of polymeric microparticles having functionality adapted to react with a crosslinking agent and a hydrophilic crosslinking agent reactive with the functionality of the microparticles. The microparticles are prepared from one or more reaction products of ethylenically unsaturated monomers, one or more hydrophobic polymers and one or more hydrophobic crosslinking agents. Pigmented film-forming compositions as well as curable compositions containing the above-described dispersions also are provided. A method of forming the dispersion of polymeric microparticles is provided.
