Patent ID: 8901234

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) a monomer having a maleimide group, and (iii) styrene, and (2) a thermal polymerization inhibitor, wherein the monomer having a maleimide group is contained in the monomer composition in an amount of not less than 5.0 wt. % but not more than 20 wt. %, wherein an 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, an 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 the adhesive composition remains soluble in propylene glycol monomethyl ether acetate even if the adhesive composition is heated at 250° C. for 1 hour.
