<p>A coating composition which cures at ambient temperatures and contains 20-80% by weight of a binder and 80-20% by weight of a solvent for the binder, wherein the binder contains about: A. 60-80% by weight, based on the weight of the binder, of an acrylic polymer A of polymerized monomers of methyl methacrylate and monomers of styrene, alkyl methacrylate and/or alkyl acrylate each having 2-12 carbon atoms in the alkyl group and said polymer having pending from the polymer backbone aminoester groups, hydroxy aminoester groups or hydroxyamine groups, B. 20-40% by weight, based on the weight of the binder, of an acrylic crosslinking polymer B of polymerized monomers of at least 3% by weight, based on the weight of the crosslinking polymer, of a glycidyl constituent of glycidyl methacrylate or acrylate, at least 5% by weight, based on the weight of the crosslinking polymer, of an alkyl methacrylate or acrylate having a pendent group of the formula <CHEM> and the remainder of the monomers are alkyl methacrylate an acrylate each having 1-12 carbon atoms in the alkyl group; the composition is useful as an exterior finish for automobiles and trucks and for repairing and finishes of automobiles and trucks. n</p> |
