Title: MULTILAYER OPTICAL FILM, METHOD FOR PREPARING SAME AND POLARIZING PLATE COMPRISING SAME
Abstract:
The present invention relates to a multilayer optical film, a method for preparing same, and a polarizing plate comprising same, wherein the multilayer optical film comprises: a first film layer formed of a thermoplastic acryl-based resin composition including 0.01 to 2.0 parts by weight of a triazine-based ultraviolet ray absorbing agent based on 100 parts by weight of a thermoplastic acryl-based resin composition; a second film layer formed of a thermoplastic acryl-based resin composition including 0.1 to 5.0 parts by weight of one or more ultraviolet ray absorbing agent(s) selected from the group consisting of triazole-based, benzophenon-based, oxanilide-based and cyanoacryl-based ultraviolet ray absorbing agents; and a third film layer formed of a thermoplastic acryl-based resin composition including 0.01 to 2.0 parts by weight of triazine-based ultraviolet ray absorbing agent.
