OPTICAL FILM AND METHOD FOR PRODUCING THE SAME

摘要

Disclosed is an optical film in which a hard coat layer comprising a curable resin precursor that has been cured, a thermoplastic resin, and microparticles having an average primary particle diameter of 1 to 100 nm is formed on at least one surface of a transparent film. The thermoplastic resin can be a thermoplastic resin (particularly a cellulose derivative) that is nonreactive with the curable resin precursor. The ratio of metal oxide microparticles is 0.5 to 4 parts by weight per 100 parts by weight of the curable resin precursor. The metal oxide microparticles can be at least one type of microparticles selected from the group comprising antimony-containing tin oxide, tin oxide, and zinc oxide. The curable resin precursor can be a precursor having four functional groups or more. The optical film has excellent anti-glare properties or anti-Newton ring properties, and has excellent scratch resistance and mechanical characteristics.
