Abstract: Disclosed is a coating composition including: (a) an acrylic polymer prepared by copolymerizing about 2.5 to about 30% by weight of an alkoxysilane-containing vinyl monomer which is represented by the formula ##STR1## wherein A is ##STR2## R.sub.1 is a hydrogen atom or a methyl group, R.sub.2 is a bivalent aliphatic saturated hydrocarbon group having 1 to 6 carbon atoms, R.sub.3 and R.sub.4 are the same or different and are each a phenyl group, an alkyl group having 1 to 6 carbon atoms or an alkoxy group having 1 to 10 carbon atoms, R.sub.5 is an alkyl group having 1 to 10 carbon atoms, and n is an integer of 1 to 100, about 5 to about 50% by weight of an acetoacetoxy-containing vinyl monomer and about 20 to about 92.5% by weight of a vinyl monomer which is copolymerizable with the above vinyl monomers, and (b) an amino resin in an amount of about 5 to about 50% by weight based on the total amount of resin solids in the coating composition.
