摘要:
An adhesive for polarizing plate used in order to provide a transparent protective film on at least one surface of a polarizer, comprising a crosslinking agent in the range of more than 30 parts by weight and 46 parts by weight or less relative to 100 parts by weight of a polyvinyl alcohol-based resin having an acetoacetyl group, is excellent in water resistance.
