  • Patent number: 9556365
    Abstract: Provided are a pressure-sensitive adhesive composition for a touch panel, a conductive film, a touch panel and a pressure-sensitive adhesive film. The exemplary pressure-sensitive adhesive composition for a touch panel, the conductive film or the pressure-sensitive adhesive film has excellent durability and optical properties such as transparency. In addition, such physical properties are stably maintained under severe conditions. Particularly, a pressure-sensitive adhesive layer is attached to a conductor thin film, and thus resistance change of the conductor thin film is effectively inhibited even when the conductor thin film is exposed to the severe conditions. Therefore, the pressure-sensitive adhesive composition may be effectively used to manufacture a touch panel.
