ADHESIVE AGENT COMPOSITION, ADHESIVE SHEET, OPTICAL ADHESIVE SHEET AND ELECTROMAGNETIC WAVE SHIELDING ADHESIVE SHEET

摘要

An adhesive sheet that excels in reworkability and is high in the mechanical strength after application. There is disclosed an adhesive agent composition comprising a copolymer resulting from copolymerization of a macromonomer, a monomer having a functional group and an alkyl (meth)acrylate. The adhesive agent layer (15) resulting from sheeting of the adhesive agent composition is flexible, can adhere to an adherend with level differences and, even after stuck once to an adherend and detached, is free from adhesive transfer, thereby excelling in reworkability. Strong adhesion is realized by, after application to an adherend, applying a high load or heating, so that the adherend can be strongly fixed by the adhesive agent layer (15).
