Title:
OPTICAL FILM, AND USE AND PRODUCTION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2008/007590
Kind Code:
A1
Abstract:
Disclosed is an optical film having antistatic properties, which is characterized in that a norbornene resin film (A) and an antistatic layer (B), which is made of an antistatic coating material containing a specific acrylic resin (b1) having a quaternary ammonium salt in a side chain and a curing agent (b2) composed of a polyethyleneimine and/or a polyhydroxyalkane polyglycidyl ether, are arranged in layers. Specifically disclosed is an optical film made of a norbornene resin, which film is excellent in characteristics such as adhesion, transparency, heat resistance and chemical resistance, while having excellent durability. This optical film maintains excellent antistatic properties over a long time. Also specifically disclosed are a method for producing the optical film, a polarizing plate using the optical film, and a liquid crystal display using the polarizing plate.
