OPTICAL FILM EXHIBITING EXCELLENT BLOCKING PROPERTY FOR ULTRAVIOLET RAYS AND POLARIZING PLATE COMPRISING THE SAME

摘要

The present invention relates to an optical film including an acrylic resin, a hindered amine light stabilizer (HALS), and a UV absorber which has a first peak having 0.07 to 0.10 phr-1μm-1 of maximum absorption coefficient in a wavelength band of 290 to 320 nm and a second peak having 0.11 to 0.16 phr-1μm-1 of maximum absorption coefficient in a wavelength band of 330 to 440 nm; and a polarizing plate including the same. [Reference numerals] (AA) NST5 + UV94 primary stage; (BB) NST5 + UV94 after 100 hours; (CC) Transmittance(%); (DD) Wavelength(nm)
