Adhesive composition for polarizing plate, adhesive film for polarizing plate prepared using the same, polarizing plate comprising the same and optical display comprising the same
An adhesive composition for polarizing plates includes a (meth)acrylic copolymer, an isocyanate crosslinking agent, and a silane coupling agent. The molar ratio (A) of the number of moles of hydroxyl groups in the (meth)acrylic copolymer may be about 2.5 mol % to about 4 mol %, the molar ratio (B) of the number of moles of alkoxy silane groups in the silane coupling agent may be about 50 mol % to about 80 mol %, and the molar ratio (C) of the number of moles of isocyanate groups of the isocyanate crosslinking agent may be about 20 mol % to about 50 mol %, based on the total number of moles of alkoxy silane groups of the silane coupling agent and isocyanate groups of the isocyanate crosslinking agent. An adhesive film is formed from the adhesive composition, a polarizing plate includes the adhesive film, and an optical display includes the polarizing plate.
