ADHESIVE COMPOSITION, ADHESIVE LAYER AND POLARIZING PLATE USING THE SAME

摘要

PURPOSE: An adhesive composition is provided to obtain an adhesion and durability for adhesive by using a low molecular weight copolymer and to reduce curing period. CONSTITUTION: An adhesive composition comprises an acrylic copolymer, an isocyanate-based crosslinking agent, a polyfunctional (meth)acrylate monomer, and a photopolymerization initiator. The acrylic copolymer is obtained by copolymerizing 94-99 weight% of a (meth)acrylate monomer with a C1-12 alkyl group; and 1-6 weight% of a polymerizable monomer which contains an amide-containing monomer, a carboxy-containing monomer, and a hydroxy-containing monomer. The weight ratio of the amide-containing monomer to the carboxy-containing monomer is 0.5-10. The weight average molecular weight of the adhesive composition is 200,000-900,000.
