To provide an adhesive composition being excellent in heat resistance, adhesive strength under high temperature conditions and alkali resistance and easy in peeling after a high temperature process.; The adhesive composition is composed mainly of a polymer prepared by the copolymerization of a monomer composition comprising styrene, a (meth)acrylate having a cyclic structure and an alkyl (meth)acrylate having a chain structure. And the monomer composition may further contain a carboxylic acid having an ethylenic double bond, a bifunctional monomer and a styrene macromonomer, and, when the polymer contains a styrene block segment, heat resistance, adhesive strength in high temperature conditions, alkali resistance and easiness of peeling after a high temperature process are enhanced. |
