Abstract: A paint composition is provided, which comprises a copolymer comprising the following constitutional units (A), (B), and (C) as essential components: (A) a (meth)acrylate monomer unit having a straight-chain, branched-chain, or cyclic alkyl group; (B) at least one monomer unit selected from the group consisting of a monomer unit having an unsaturated double bond and a hydroxyalkyl group, a monomer unit having an unsaturated double bond and an epoxy group, and a monomer unit having an unsaturated double bond and an alkoxysilyl group; and (C) a monomer unit having an unsaturated double bond and a maleimide group. The paint composition is excellent in weatherability and coating gloss. The composition may be contained in an organic solvent such as cyclic ethers, aromatic hydrocarbons, esters, and ketones. The organic solvent may be one that comprises 40% or more of a saturated hydrocarbon.
