摘要：
An adhesive of the present invention is used for polarizing plate to provide a transparent protective film on at least one side of a polarizer and comprises a resin solution comprising a polyvinyl alcohol-based resin, a crosslinking agent and a leveling agent containing an acetylene skeleton-containing compound, wherein 0.01 to 10 parts by weight of the leveling agent is added to 100 parts by weight of the polyvinyl alcohol-based resin. The adhesive for polarizing plate can provide a satisfactory wettability when applied to transparent protective films and allows the production of polarizing plates to have water resistance at high temperature and satisfactory optical properties.
