Patent number: 9556364Abstract: 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.Type: GrantFiled: October 20, 2011Date of Patent: January 31, 2017Assignee: LG Chem, Ltd.Inventors: Min Soo Park, Se Woo Yang, Suk Ky Chang, Woo Ha Kim, Yoon Tae Hwang

Publication number: 20140057102Abstract: [Summary] The present invention relates to a touch panel. The present touch panel has a shape that comprises a plastic substrate film and a pressure sensitive adhesive layer attached to said substrate film. Here, a phenomenon of penetrating oxygen, moisture or other foreign materials into an interface between said substrate film and said pressure sensitive adhesive layer is prevented, and decrease of optical properties by bubble generation due to the out-gassing phenomenon in the plastic substrate film is prevented. In addition, even if the pressure sensitive adhesive layer is directly attached to the conductive thin film, and it is exposed to a severe condition such as high temperature or high temperature and high humidity condition as such a state, change of resistance in the conductive thin film is effectively inhibited. Therefore, the present touch panel may be stably driven for a long time.Type: ApplicationFiled: October 31, 2013Publication date: February 27, 2014Applicant: LG CHEM, LTD.Inventors: Min Soo PARK, Se Woo YANG, Woo Ha KIM, Yoon Tae HWANG, Suk Ky CHANG
