摘要

This invention provides a clear paint composition suitable for application on base coated surface of a coating object, which is characterized by comprising (a) a hydroxyl- and epoxy-containing acrylic resin, (b) a high acid value polyester resin having an acid value of 120-200 mgKOH/g and a number-average molecular weight of 500-4,000, (c) an alkoxysilyl-containing acrylic resin, and (d) an acrylic resin containing alkoxysilyl groups and dimethylpolysiloxane side chains, and forming a coating which, after being cured, has a glass transition point within a range of 100-120° C.
