Title:
CATIONIC POLYMERIZABLE ADHESIVE AND POLARIZING PLATE OBTAINED USING SAME
Document Type and Number:
WIPO Patent Application WO/2012/144261
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a cationic polymerizable adhesive having water resistance and adhesion properties excellent enough that even when the polarizing plate or the like is bent, there is no peeling away from the protective film and/or polarizer, and cracks do not form in the adhesive layer; and a polarizing plate obtained using the same. The present invention pertains to: a cationic polymerizable adhesive containing an aromatic glycidyl ether (A), an oxetane compound (B) having at least two oxetanyl groups, a silane coupling agent (C) containing an alicyclic epoxy group, and a cationic polymerization initiator (D), the cationic polymerizable adhesive being characterized by using 100 parts by mass of the aromatic glycidyl ether (A), 300-395 parts by mass of the oxetane compound (B), and 5-100 parts by mass of the silane coupling agent (C); and a polarizing plate obtained by adhering a polarizer and a protective film to one another using the same.
