Disclosed is a pressure sensitive adhesive composition characterized by containing an ionic liquid and a polymer which contains, as a monomer unit, 0.1-10% by weight of a (meth)acrylate with a hydroxyalkyl group having 3-12 carbon atoms. The present invention provides a pressure sensitive adhesive composition which is excellent in antistatic property of a no-electrification-prevented adherend upon peeling, and has reduced staining of an adherend and is excellent in adhesion reliance. Also disclosed is an antistatic pressure sensitive adhesive sheet or surface-protecting film prepared using the composition. Also disclosed is an antistatic pressure sensitive adhesive sheet or surface-protecting film prepared using the composition.
本发明公开了一种压敏型粘合剂组合物,其特征在于含有
离子液体和聚合物,其中聚合物的单体单元含有重量百分比为 0.1-10%的具有 3-12 个碳原子的羟基烷基的(甲基)
丙烯酸酯。本发明提供了一种压敏型粘合剂组合物,它在剥离时可防止被粘物的无电化,抗静电性能优异,并可减少被粘物的沾污,粘附性极佳。还公开了一种使用该组合物制备的抗静电压敏胶片或表面保护膜。还公开了一种使用该组合物制备的抗静电压敏胶片或表面保护膜。
