Patent ID: 8901235

Claim:
An adhesive composition dissolved in an organic solvent, wherein the adhesive composition comprises: (1) as a main component, a polymer obtained by copolymerizing a monomer composition comprising (i) an alkyl (meth)acrylate, (ii) monomers having a maleimide group, and (iii) styrene, and (2) a thermal polymerization inhibitor, wherein the monomers having a maleimide group are contained in the monomer composition in an amount of not less than 5.0 wt. % but not more than 40 wt. %, and the monomers having a maleimide group comprise a maleimide having an alicyclic hydrocarbon group and a maleimide having an aryl group, wherein the amount of the alkyl (meth)acrylate in the monomer composition is not less than 30 parts by weight but not more than 58 parts by weight, the amount of the styrene in the monomer composition is not less than 30 parts by weight but not more than 60 parts by weight, and the total amount of the monomer composition is 100 parts by weight, and wherein a weight-average molecular weight of the polymer is 30,000 or greater but no greater than 150,000.
