Abstract:
An adhesive composition for a polarizing plate, an adhesive film formed from the same, a polarizing plate including the same, and an optical display including the same are disclosed. The adhesive film for a polarizing plate is formed from an adhesive composition including an epoxy compound and a (meth)acrylate compound, and the adhesive film has an FT-IR peak ratio of about 0.015 or lower as defined by Equation 1. Equation 1 FT-IR peak ratio=B/A (1) In Equation 1, A is the peak height of the peak attributable to the —(C═O)— bond at 1724 cm−1, and B is the peak height of the peak attributable to the —CH═CH— bond at 1636 cm−1.
