Patent ID: 7101930

Claim:
A curable, aqueous film-forming composition comprising: a) a polymeric binder containing two or more reactive functional groups; (b) a curing agent having at least two functional groups which are reactive with the reactive functional groups of (a); and (c) a copolymer flow control agent, at least 30 mol % of the copolymer comprising residues having the following 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 following structure (1): wherein R 1 is linear or branched C 1 to C 4 alkyl, R 2 is selected from the groups consisting of methyl, linear, cyclic or branched C 1 to C 20 alkyl, alkenyl, aryl, alkaryl and aralkyl wherein components (a) and (b) are substantially hydrophobic and are prepared as an aqueous dispersion comprising polymeric microparticles, said microparticles prepared by mixing components (a) and (b) together under high shear conditions, and wherein said film-forming composition can form a generally continuous film at ambient temperatures.
