The present invention provides a pressure-sensitive adhesive which can prevent electrification of a non-electrification-prevented adherend upon peeling, suppresses occurrence of peeling off even with time or via treatment under a high temperature, and is excellent in adhesion reliance, as well as an antistatic pressure-sensitive adhesive sheet, and surface protecting film using this. The pressure-sensitive adhesive composition of the present invention contains an ionic liquid, and a polymer having a glass transition temperature of Tg of 0°C or lower as a base polymer, as well as an ethylene oxide group-containing compound and/or a surfactant.
本发明提供了一种在剥离时可防止非防静电粘合剂带电,即使经过一段时间或高温处理也可抑制剥离的发生,且粘合可靠性极佳的压敏粘合剂,以及使用该压敏粘合剂的防静电压敏胶片和表面保护膜。本发明的压敏胶组合物含有离子液体、玻璃化温度 Tg 为 0°C 或更低的聚合物作为基体聚合物,以及含环氧乙烷基团的化合物和/或表面活性剂。
