ADHESIVE LAYER FOR ELECTRIC INSULATION, ADHESIVE FILM FOR ELECTRIC INSULATION, AND OPTICAL MEMBER WITH THE FILM ADHERED

摘要

PROBLEM TO BE SOLVED: To provide an adhesive layer for electric insulation which has a low dielectric constant, excellent insulation performance and turbidity prevention performance at high temperature and high humidity, while the adhesive layer comprising an adhesive composition containing only an acrylic monomer having a general structure as a main component, and to provide an adhesive film for electric insulation, and an optical member to which the adhesive film is adhered.SOLUTION: An adhesive layer for electric insulation is obtained by crosslinking an acrylic copolymer having a polyalkylene oxide chain in a side chain. The adhesive layer for electric insulation is obtained by crosslinking an adhesive composition that comprises a crosslinking agent and the above acrylic copolymer prepared by copolymerizing a polyalkylene glycol (meth)acrylate monomer and a copolymerizable vinyl monomer having a vinyl group.
