    摘要： Provided is a touch panel. The touch panel includes a base and a pressure-sensitive adhesive layer attached to the base and having a peel strength with respect to a polycarbonate sheet of 1,900 g/25 mm or more. The pressure-sensitive adhesive layer includes an acryl polymer compound containing an acryl polymer and a thiol polymer derived by binding a thiol compound into a chain, or a side chain or terminal end of a chain of the acryl polymer. Accordingly, penetration of oxygen, moisture or other impurities at an interface between the base film and the pressure-sensitive adhesive layer, or at an interface between a conductor thin film and a pressure-sensitive adhesive layer may be effectively inhibited, and degradation in optical properties such as visibility due to bubbles generated at a pressure-sensitive adhesive interface may be prevented. In addition, when the pressure-sensitive adhesive layer is directly attached to the conductor thin film and even exposed to severe conditions such as high temperature or high temperature and high humidity, the change in the resistance of the conductor thin film may be effectively inhibited, and thus the touch panel may be stably driven for a long time.

    摘要： Provided is a touch panel. The touch panel includes a base and a pressure-sensitive adhesive layer attached to the base and including an acryl-based polymer containing an acryl polymer containing 5 to 30 parts by weight of isobornyl (meth)acrylate, and 5 to 40 parts by weight of methyl (meth)acrylate in a polymerized form. Accordingly, it can effectively inhibit penetration of oxygen, moisture or other impurities at an interface between the base and the pressure-sensitive adhesive layer, or at an interface between a conductor thin film and the pressure-sensitive adhesive layer, and prevent degradation in optical properties such as visibility, etc. due to bubbles generated at the pressure-sensitive adhesive interface. In addition, when the pressure-sensitive adhesive layer is directly attached to the conductor thin film and even exposed to severe conditions such as high temperature or high temperature and high humidity, a change in the resistance of the conductor thin film may be effectively inhibited, and thus the touch panel can be stably driven for a long time.

    摘要翻译： 提供触摸屏。 触摸面板包括底座和压敏粘合剂层，所述底座和粘合剂层附着到基底上，并且包括含有丙烯酸类聚合物的丙烯酸类聚合物，所述丙烯酸类聚合物含有5-30重量份的（甲基）丙烯酸异冰片酯，和5-40重量份的 （甲基）丙烯酸甲酯。 因此，能够有效地抑制基材与压敏粘合剂层之间的界面，导体薄膜与压敏粘合剂层之间的界面处的氧气，水分或其他杂质的渗透，防止光学降解 由于在压敏粘合剂界面产生的气泡等可见性等特性。 此外，当压敏粘合剂层直接附着在导体薄膜上并且甚至暴露于诸如高温或高温和高湿度的严酷条件下时，可以有效地抑制导体薄膜的电阻变化， 因此能够长时间稳定地驱动触摸面板。
