Abstract
The present invention has its object to provide an acrylic curable composition which is improved in tackiness, retention and other adhesive properties without reducing the thermal stability and weather resistance. The above-mentioned object can be solved by a curable composition which comprises, as an essential component, polymer (I), which is a (meth)acrylic acid ester copolymer having, in each molecule, at least one group represented by the general formula 1: --OC(O)C(R.sup.a).dbd.CH.sub.2 (1) (wherein R.sup.a represents a hydrogen atom or a hydrocarbon group containing 1 to 20 carbon atoms) at a terminus of the molecular chain and is obtained by (co)polymerizing an (meth)acrylic acid alkyl ester the alkyl moiety of which contains 7 to 20 carbon atoms.
