Patent ID: 10190025

Abstract:
An adhesive composition for a polarizing plate of the present invention comprises, on the basis of 100 parts by weight of a polymerizable component: the polymerizable component comprising (A) approximately 50-90 parts by weight of an epoxy group-containing compound and (B) approximately 10-50 parts by weight of a (meth)acrylate monomer; (C) approximately 1-7 parts by weight of a photoacid generator; and (D) approximately 0.1-7 parts by weight of at least one between a photosensitizer and a photopolymerization initiator, wherein the epoxy group-containing compound (A) comprises: (A1) approximately 50-95 parts by weight of an alicyclic epoxy group-containing compound; and (A2) 1 to approximately 50 parts by weight of an aromatic group-containing epoxy group-containing compound, on the basis of 100 parts by weight of the epoxy group-containing compound (A), and the mass ratio of the alicyclic epoxy group-containing compound (A1) to the aromatic group-containing epoxy group-containing compound (A2) can be approximately 3:1 to approximately 95:1. Accordingly, embodiments of the present invention can provide: an adhesive composition for a polarizing plate, having all the properties of sufficient initial curing, adhesion and reliance; and a polarizing plate and an optical display device comprising the same.
