Polarized thin film

Abstract

A polarizing film is an optical film bonded to the easy-bond layer of a polarizing element with an easy-bond layer through an adhesive layer; the optical film is a resin film selected from at least one resin film of the group consisting of polyester resin, (meth)acrylic resin, polystyrene resin and polycarbonate resin; the adhesive composition satisfies the condition of a white turbidity water absorption rate of 2.8 or more; and the easy-bond composition contains water, a (meth)acrylamide derivative containing a cyclic ether group and a compound of general formula (1). The polarizing film is an optical film bonded to the easy-bond layer of a polarizing element with an easy-bond layer through an adhesive layer, and it still has a good appearance even when using a resin film selected from at least one resin film of the group consisting of polyester resin, (meth)acrylic resin, polystyrene resin and polycarbonate resin as the optical film.
