ADHESIVE AGENT COMPOSITION, ADHESIVE AGENT LAYER, AND ADHESIVE SHEET

摘要

A pressure-sensitive adhesive composition of the invention includes a (meth)acryl-based polymer obtained by polymerization of a monomer component including 25% by weight to 99.5% by weight of a cyclic structure-containing monomer and 0.5% by weight to 70% by weight of a branched structure-containing (meth)acryl-based monomer having a branched alkyl group of 3 to 18 carbon atoms at an ester end. The pressure-sensitive adhesive composition has a satisfactory level of adhesive performance and can form a pressure-sensitive adhesive layer with a lower dielectric constant.
