Adhesive composition for optical use, method for preparing adhesive composition for optical use, and adhesive film for optical use
The present invention provides an adhesive composition for optical use, which includes rubber and may be chemically cross-linked through an appropriate curing process, and as a result, may secure excellent long-term durability, water vapor transmission resistance, and chemical resistance, and includes an isobutylene-isoprene rubber having an acrylic acid ester-based functional group in a main chain thereof, a photoinitiator, and a tackifier in order to provide optical characteristics sufficient to be used for optical use. The present invention provides a method for preparing the adhesive composition for optical use, and it is possible to obtain the adhesive composition for optical use, which includes a chemically cross-linkable rubber by the method. Further, the present invention provides an adhesive film for optical use, and excellent long-term durability and optical characteristics may be implemented by applying the adhesive film for optical use to a wide range of electronic devices.
