OPTICAL ADHESIVE COMPOSITION, OPTICAL ADHESIVE SHEET, IMAGING DISPLAY DEVICE, AND INPUT AND OUTPUT APPARATUS

摘要

The present invention has the subject of providing an optical adhesive composition which can provide an adhesive layer having excellent adhesion while having low permittivity, an optical adhesive sheet obtained by using the optical adhesive composition, and an imaging display device including the optical adhesive sheet, and an input and output apparatus. The optical adhesive composition as a means for solving the subject contains a copolymer (A) of a monomer mixture (here, component (a1) and component (a2) are 45 wt% or more and 100 wt% or less in total) containing (a1) 3 wt% or more and 39 wt% or less of methacrylic acid alkyl ester monomer having an alkyl group of 10 or more and 18 or less carbon atoms; and (a2) 20 wt% or more and 97 wt% or less of a methacarylic acid alkyl ester monomer having an alkyl group of one or more and nine or less carbon atoms.
