<p>PURPOSE: An adhesive composition for a polarizing plate is provided to facilitate the attachment of an inadhesive protection film and to have excellent adhesion with a polarizer and a polarizer protection film and water resistance in a high temperature and high humidity condition. CONSTITUTION: An adhesive composition includes a repeating unit which includes chemical formula 1, chemical formula 2, or a mixed polyallylammonium salt-based resin and a crosslinking agent. In the chemical formulas, each of R1, R2, R3, R4, and R5 is independently hydrogen or an alkyl group; X is Cl^-, CH3COO^-, C2H5SO4^-, or SO3^-. The polyalyl ammonium-based resin has a weight average molecular weight of 5,000-150,000. A polarizing plate includes a polarizer (4) and an adhesive layer which is laminated on one side or both sides of the polarizer and the adhesive composition; and a polarizing protection film laminated on the adhesive layer.</p> |
