ADHESIVE COMPOSITION FOR OPTICAL APPLICATIONS ADHESIVE LAYER FOR OPTICAL APPLICATIONS OPTICAL MEMBER POLARIZING PLATE AND IMAGE DISPLAY DEVICE

摘要

A point adhesive layer, an optical member, and an image display device, which can be used for an optical member which can suppress brightness unevenness without deteriorating the contrast property for optical use and which is not peeled off under a reliability test . (Meth) acrylic graft polymer, and 0.01 to 1.80 parts by weight of an isocyanate crosslinking agent. The modified (meth) acrylic graft polymer is obtained by graft-polymerizing a chain containing a cyclic ether group-containing monomer onto a trunk polymer (Meth) acrylate, a cyclic ether group-containing monomer and a noncyclic ether group-containing monomer as constituent components, and in the modified (meth) acryl group graft polymer, the cyclic ether group- An optical point-bonding adhesive composition containing 8 to 40 parts by weight based on 100 parts by weight of the total amount of other monomer components constituting the composition is prepared, and an optical point-bonding adhesive layer for optical, optical member and image display device do.
