An active energy beam-curable adhesive composition is provided. The adhesive composition comprises (A), (B), and if required, (C) components. The component (A) is urethane (meth)acrylate derived from polyester polyol or polycarbonate polyol. The component (B) is a compound having at least one ethylenically unsaturated group together with at least one a cyclic imide group represented by the following general formula (1) . Further, the component (C) is a compound having at least one ethylenically unsaturated group other than the components (A) and (B):

Active energy beam-curable adhesive composition

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. In this case, it is preferred that a (meth)acrylic ester monomer having an alkyl group of 8 to 20 carbon atoms accounts for 5 to 50% by weight of the total amount of the constitutional units of the copolymer.
