A pressure-sensitive adhesive sheet 1 provided by the present invention is provided with a substrate film 12 comprising a transparent resin material, an antistatic layer 14 provided on a first side 12A thereof, and a pressure-sensitive adhesive layer 20 provided on a second side 12B thereof. The antistatic layer 14 contains an antistatic component (for example, an electroconductive polymer) and a binder resin, and has an average thickness Dave of 1 nm to less than 100 nm. The pressure-sensitive adhesive layer 20 contains an acrylic polymer as a base polymer and an ionic compound (such as an ionic liquid and alkaline metal salt) as an antistatic component.
本发明提供的压敏胶片 1 具有由透明树脂材料构成的基底膜 12、设置在其第一面 12A 上的抗静电层 14 以及设置在其第二面 12B 上的压敏胶层 20。抗静电层 14 包含抗静电成分(例如导电聚合物)和粘合剂树脂,其平均厚度 Dave 为 1 纳米至小于 100 纳米。压敏粘合剂层 20 包含作为基础聚合物的丙烯酸聚合物和作为抗静电成分的离子化合物(例如离子液体和碱金属盐)。
