    • Provided is a pressure-sensitive adhesive for an optically functional film which can carry out adhesion with a good durability in adhesion of an optically functional film such as adhesion of a polarizing plate, particularly a polarizing plate integrated with a viewing angle expanding film and the like with a liquid crystal cell, adhesion of a polarizing plate with a retardation film, adhesion of a retardation film with a retardation film and adhesion of a retardation film with a liquid crystal cell and which has the characteristics that a liquid crystal display obtained therefrom is less liable to cause light leakage even under the environment of high temperature and high humidity and that static electricity is less liable to be produced when peeling off a release film from a pressure-sensitive adhesive layer.The pressure-sensitive adhesive for applying an optically functional film comprises a pressure-sensitive adhesive resin and an antistatic agent, wherein a storage elastic modulus (G′) at 23° C. is 0.3 MPa or more, and a charged voltage on the surface of a layer comprising the above pressure-sensitive adhesive which is measured 5 seconds later since peeling off a release film brought into contact with the above pressure-sensitive adhesive layer under the environment of 23° C. and a relative humidity of 50% is 1.0 kV or less.
    • 提供一种用于光学功能膜的粘合剂,其可以在光学功能膜的粘附性方面具有良好的耐久性,例如粘合偏振片,特别是与视角扩展膜一体化的偏振片等 具有液晶单元,偏振板与延迟膜的粘合,相位差膜与延迟膜的粘合性以及相位差膜与液晶单元的粘附性,具有由其获得的液晶显示器的特性较小 即使在高温高湿的环境下也容易引起漏光,并且当从压敏粘合剂层剥离剥离膜时静电不易产生。 用于施加光学功能膜的压敏粘合剂包括压敏粘合剂树脂和抗静电剂,其中23℃下的储能弹性模量(G')为0.3MPa以上,表面上的充电电压 包含上述压敏粘合剂的层,其在23℃,相对湿度为50%的环境下剥离与上述压敏粘合剂层接触的剥离膜5秒钟后测量为1.0 kV以下。
