Abstract

PURPOSE: To improve moisture resistance and workability by coating one side of a polarizing plate with a coating compounded with an urethane resin and a saturated polyester resin (main component is polyethylene terephthalate) at the specific ratio.
CONSTITUTION: The coating compounded with an urethane resin A comprising isocyanate more than bifunctional etc. and a saturated polyester resin (main component is polyethylene terephthalate) B dissolved with "Pylon" etc. of ≥10,000 molecular weight in a solvent such as ethyl acetate having no active hydrogen that reacts with isocyanate in such a manner that the ratios thereof become 20W150pts to 100pts is coated on at least one side of a polarizing film. As a result, the adhesion between the polarizing film and the resin layer becomes firm and moisture rsistance and workability may be improved.
