PHOTOCROSSLINKABLE TRANSPARENT ADHESIVE MATERIAL, TRANSPARENT ADHESIVE MATERIAL LAYERED BODY, AND LAYERED BODY FOR CONSTITUTING OPTICAL DEVICE

摘要

Provided is a novel transparent adhesive material having low relative permittivity as well as excellent adhesive characteristics, whereby an olefinic polymer resin layer and an acrylic polymer adhesive layer can be suitably integrated. A transparent adhesive material provided with an outermost surface layer containing an acrylic polymer (B) and a photocrosslinking initiator, and an intermediate layer containing an olefinic polymer (A), a crosslinking agent, and a photocrosslinking initiator, the photocrosslinkable transparent adhesive material characterized in that the intermediate layer contains a (meth)acrylate monomer as the crosslinking agent.
