CATIONIC POLYMERIZABLE ADHESIVE AND POLARIZING PLATE OBTAINED USING SAME

WIPO Patent Application WO/2012/144260

A1

The present invention addresses the problem of providing: a cationic polymerizable adhesive having excellent adhesion strength to not only various protective films, but also specifically to an acrylic resin film; 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, an alicyclic epoxy compound (C) represented by general formula (7), and a cationic polymerization initiator (D), the cationic polymerizable adhesive being characterized by using 100 parts by mass of the aromatic glycidyl ether (A), 120-380 parts by mass of the oxetane compound (B), and 15-280 parts by mass of the alicyclic epoxy compound (C); and a polarizing plate obtained by adhering a polarizer and a protective film to one another using the same.
