  • Publication number: 20150125675
    Abstract: The present invention relates to an optical adhesive film which has excellent adhesive strength at room temperature and has improved efficiency in a rework process since peel strength is low at high temperatures. When attaching a touchscreen panel and an LCD by using the adhesive film of the present invention and separating the touchscreen panel and the LCD at high temperatures, the touchscreen panel and the LCD can be separated from each other without causing damage thereto. Additionally, the optical film of the present invention comprises two adhesive layers, wherein peeling occurs at the first adhesive layer having an adhesive composition such that a peeling surface can be controlled according to the convenience of a user.
