<p>An optical film coated with an adhesive is provided to realize enhanced anti-static property and excellent durability, thereby inhibiting an optical member from being charged and preventing separation of an adhesive layer from a substrate. An optical film has an adhesive layer on at least one surface thereof, wherein the adhesive layer is formed from a composition comprising: (A) an acrylic resin based on a first acrylic resin having repeating units derived from a (meth)acrylate represented by the following formula I, an olefinic double bond, and repeating units derived from an unsaturated monomer having at least one hydroxyl group in the molecule, and having a weight average molecular weight of 500,000-2,000,000(wherein the repeating units derived from an unsaturated monomer having at least one hydroxyl group is present in an amount of 0.5-10 parts by weight per 100 parts by weight of the acrylic resin); (B) an ionic compound containing a pyridinium-based cation represented by the following formula II; and (C) a crosslinking agent. In formula I, R1 is H or CH3, and R2 is a C1-C14 alkyl or aralkyl capable of being substituted with a C1-C10 alkoxy group. In formula II, at least one of R3-R7 is a C1-C6 alkyl group, and the others represent H or a C1-C6 alkyl group, and R8 is a C1-C12 alkyl group.</p> |
