PROTECTIVE FILM FOR POLARIZING PLATE AND POLARIZING PLATE

摘要

PROBLEM TO BE SOLVED: To provide a protective film for a polarizing plate which is less in loss, high in an yield and low in a cost by attaining the compatibility of flawing resistance with an antistatic property and the polarizing plate formed by using this film. SOLUTION: This protective film and polarizing plate have antistatic layers contg. ionomer conductive polymers and hydrophobic binders or the antistatic layers contg. quaternary ammonium cation conductive polymers having polymer molecule crosslinking on one surface of transparent plastic films, have cured film layers formed by irradiating the layers contg. UV curing resin compsn. with UV rays to cure the compsn. on these antistatic layers and have easily adhesive layers contg. hydrophilic polymers on the other surfaces or PVA hydrophilic layers on these easily adhesive layers. The protective film for the polarizing plate is used for the polarizing plate used for a liquid crystal display device panel, by which the low-loss and inexpensive polarizing plate substantially free from rubbing flaws and pickup of dust is provided.
