ADHESIVE COMPOSITION FOR OPTICAL USE, ADHESIVE SHEET FOR OPTICAL SHEET, AND OPTICAL LAMINATE

Japanese Patent JP2015157913

A

PROBLEM TO BE SOLVED: To provide an adhesive composition for optical use, which gives an adhesive sheet for optical use having such properties that the adhesive sheet has a low dielectric constant, is hardly turned into a turbid state even exposed to a high temperature and high humidity environment, hardly induces foaming or peeling in a high temperature environment or in a high temperature and high humidity environment even when the sheet is laminated with an adherend such as a resin plate, and has excellent followability to a stepped portion.SOLUTION: The adhesive composition for optical use comprises a copolymer obtained by using the following monomer components and copolymerizing the monomer components. The monomer components include: an alkyl (meth)acrylate having an alkyl group having 3 to 9 carbon atoms, by 30 wt.% or more and 80 wt.% or less; an alkyl (meth)acrylate having a branched alkyl group having 10 to 20 carbon atoms, by 5 wt.% or more and 50 wt.% or less; and a N,N-dimethyl acrylamide by 5 wt.% or more and 25 wt.% or less.
