An adhesive, an adhesive layer, and a pressure sensitive adhesive sheet

Title:

An adhesive, an adhesive layer, and a pressure sensitive adhesive sheet

Document Type and Number:

Japanese Patent JP6038469

Kind Code:

B2

Abstract:

A pressure-sensitive adhesive of the invention includes a (meth)acryl-based polymer obtained by polymerization of a monomer component including: an alkyl(meth)acrylate (a1) having a branched alkyl group of 8 to 24 carbon atoms at an ester end; and an alkyl(meth)acrylate (a2) having a linear alkyl group of 8 to 24 carbon atoms at an ester end. The pressure-sensitive adhesive can has a satisfactory level of adhesive performance and can form a pressure-sensitive adhesive layer with a lower dielectric constant.
