Photocurable sheet-type adhesive composition for optical use |
摘要 |
An object of the present invention is to provide a photocurable sheet-type adhesive composition for optical use, which is used for bonding cover glass and a touch panel, a touch panel and a display module, or the like, and has high appearance reliability and storage stability even under high temperature and high humidity.;The present invention is a photocurable sheet-shape adhesive for optical use, which contains the following components (A) to (D): (A) 100 parts by mass of a urethane (meth)acrylate oligomer having a weight average molecular weight of 20,000 to 100,000; (B) 3 to 70 parts by mass of a phenoxy resin having a glass transition temperature of 50 to 120° C.; (C) 0.1 to 10 parts by mass of a photopolymerization initiator; and (D) 1 to 50 parts by mass of a (meth)acrylate monomer which has 8 to 30 repeated blocks having an ether linkage in the molecule and containing at least one (meth)acryloyl group in the molecule. |
