Abstract

A coated substrate is provided which includes an outer coating formed from a film-forming composition which includes a crosslinkable, non-gelled acrylic polymer and a crosslinking material capable of reacting with the acrylic polymer to form a crosslinked outer coating. The acrylic polymer is the reaction product of a polyoxyalkylene acrylate monomer comprising a terminal alkoxy group containing about 1 to about 6 carbon atoms and a copolymerizable ethylenically unsaturated monomer different from the polyoxyalkylene acrylate monomer. A multi-component composite coating composition is also provided.
