Summary: | PURPOSE: A protective film for a polarizing plate is provided to ensure optical properties such as transparency, thereby enabling the arrangement inside LCD and excellent anti-electrostatic property and electromagnetic wave shielding property. CONSTITUTION: A protective film for a polarizing plate is a conducted polymer film having a conductive polymer layer in which a conductive polymer is attached to the surface of the polymer film. The conductive polymer is polythiophene or their derivative. The polymer film is an acetylcellulose-based film or a norbornene-based film. The uctive polymer layer includes 0.1-500 parts by weight of a copolymer in which polystyrenesulfonic acid ion and polystyrenesulfonic acid are copolymerized in a molar ratio of 1:1 as a doping agent based on 100.0 parts by weight of polythiophene or derivative thereof. The thickness of the conductive polymer layer is 3 micron or less, the transmittance of the visible ray is 78% or more, and surface intrinsic resistance value is 10^3 - 10^12 Ω/ . |
