PURPOSE:To stabilize quality of a polarizing plate by providing a pressure-sensitive adhesive agent layer consisting of a crosslinked acrylic copolymer and non- crosslinked acrylic (co)polymer as a pressure-sensitive adhesive agent layer to be provided on a polarizable film. CONSTITUTION:(A) a copolymer consisting of 70-99.9mol% alkyl (meth)acrylate and 20-0.1mol% polymerizable monomer having a reactive functional group (e.g.; hydroxyl group), (B) a (co)polymer consisting essentially of alkyl (meth)acrylate and having no reactive functional group and (C) a multifunctional comp. having plural functional groups (e.g.; isocyanate group) which can react with the reactive functional group of the component A are mixed in such a way that the ratio of the component A: the component B attains 4:1-1:4 and the component A is crosslinked by the component C by which a pressure-sensitive adhesive agent is prepd. Such adhesive agent is coated on the surface of a polarizable film, by which the intended polarizing plate is obtd. |
