<P>PROBLEM TO BE SOLVED: To provide an optical film having sufficient light resistance while avoiding degradation in curling property, by adding a UV absorbent having a specified structure to an antistatic hard coat layer. <P>SOLUTION: The optical film comprises a UV absorbing antistatic hard coat layer formed on one surface of a transparent base film. The hard coat layer is formed by curing the following coating liquid with UV rays to a thickness of 0.5 to 10 μm. The coating liquid comprises (A) 100 parts by mass of a UV-curing resin, (B) 1 to 20 parts by mass of a quaternary ammonium salt copolymer, (C) 1 to 20 parts by mass of a UV absorbent comprising a reaction product of 2-2(2,4-dihydroxyphenyl)-4,6-bis-(4-biphenyl)-1,3,5-triazine and 2-hydroxypropanoic acid ester, and (D) 0.1 to 10 parts by mass of a photopolymerization initiator. <P>COPYRIGHT: (C)2013,JPO&INPIT |
