Abstract
The present invention provides a thermosetting liquid coating composition for an aluminum wheel comprising (A) a hydroxy- and carboxy-containing acrylic resin having a hydroxyl value of 90 to 150 mg KOH/g and an acid value of 1 to 30 mg KOH/g, the acrylic resin being obtained by copolymerizing a monomer mixture comprising 10 to 50 wt. % of a C6-18 alkyl ester of (meth)acrylic acid, 8 to 40 wt. % of a secondary hydroxy-containing unsaturated monomer, and a carboxy-containing unsaturated monomer; and (B) an amino resin. Also provided a method of coating an aluminum wheel using the composition.
