    • PROBLEM TO BE SOLVED: To provide a pressure sensitive adhesive composition that has moderate adhesive strength at an ordinary state and characteristics imparting high adhesive strength at a high temperature and high humidity, and is suitable for laminating an optical member, such as a polarizing plate and a phase contrast plate, to a glass substrate, etc., and to provide a pressure sensitive optical member that has a layer of the composition on the optical member of the polarizing plate and the retardation plate, etc. SOLUTION: This pressure sensitive adhesive composition comprises a (meth)acrylate copolymer (A) that is obtained by copolymerization of a (meth)acrylate (a), an alkoxysilyl group-containing monomer (b) and other functional group-containing monomer (c), and a crosslinking agent (B), wherein the (meth)acrylate copolymer of component (A) is crosslinked by the crosslinking agent of component (B). The pressure sensitive adhesive optical member has the layer of the composition on at least one side of the optical member. COPYRIGHT: (C)2005,JPO&NCIPI
    • 解决的问题:提供一种在普通状态下具有适度的粘合强度和在高温高湿下赋予高粘合强度的特性的压敏粘合剂组合物,并且适用于将光学部件 偏光板和相位差板,玻璃基板等,并提供在偏光板和延迟板等的光学部件上具有该组成层的压敏光学部件。解决方案 :该压敏粘合剂组合物包含(甲基)丙烯酸酯(a),含烷氧基甲硅烷基的单体(b)和其它含官能团的单体(c)共聚得到的(甲基)丙烯酸酯共聚物(A) 和交联剂(B),其中组分(A)的(甲基)丙烯酸酯共聚物通过组分(B)的交联剂交联。 所述压敏粘合剂光学构件在所述光学构件的至少一侧具有所述组成层。 版权所有(C)2005,JPO&NCIPI
