Abstract
An adhesive of the 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 colloidal metal compound with an average particle size of 1 nm to 100 nm, wherein 200 parts by weight or less of the colloidal metal compound is added to 100 parts by weight of the polyvinyl alcohol-based resin. The adhesive for polarizing plate can reduce the occurrence of knicks.
