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.

摘要翻译： 提供了触摸面板。 触摸面板包括基底和附着到基底并具有1,900g / 25mm或更大的对聚碳酸酯片材的剥离强度的压敏粘合剂层。 粘合剂层包含丙烯酸类聚合物化合物，该丙烯酸类聚合物化合物含有丙烯酸类聚合物和通过将硫醇化合物键合到丙烯酸类聚合物链的侧链或末端而得到的硫醇聚合物。 因此，可以有效地抑制氧气，水分或其他杂质渗入基膜和压敏粘合剂层之间的界面处或导电薄膜和压敏粘合剂层之间的界面处，并且可以有效地抑制光学 可以防止由于在压敏粘合剂界面处产生的气泡引起的可视性等特性。 另外，当压敏粘合剂层直接附着到导体薄膜上并且甚至暴露于苛刻条件如高温或高温和高湿度时，可以有效地抑制导体薄膜的电阻变化， 并且因此触摸面板可以被长时间稳定地驱动。
