Adhesive composition for optical use and adhesive film for optical use
The present invention relates to an adhesive composition for optical use, which is applied to optical devices or display devices and thus may exhibit excellent adhesion performance while exhibiting a high barrier performance based on a low water vapor transmission rate, and may implement both excellent optical characteristics and durability, and specifically, provides an adhesive composition for optical use, the adhesive composition including: a thermally curable rubber including an isobutylene-isoprene rubber having a carboxyl group and an isobutylene-isoprene rubber having a hydroxy group; and a thermal crosslinking agent. Further, the present invention provides an adhesive film for optical use, including an adhesive layer including photocured products of the adhesive composition for optical use.
