Patent ID: 8187704

Claim:
An optical film, comprising: a transparent support; and at least one low refractive index layer, wherein one or more of the at least one low refractive index layer is a layer formed from a coating composition containing: (A) an inorganic fine particle; (B) a fluorine-containing copolymer; and (C) a polyfunctional fluorine-containing acrylate, wherein one or more of the at least one refractive index layer has a refractive index of 1.20-1.46, and the polyfunctional fluorine-containing acrylate (C) is represented by the following structural formula: wherein Rf represents a (p+q)-valent perfluoro saturated hydrocarbon group having a carbon number of 1 to 20, which may have an ether bond; p represents an integer of 3 to 6; q represents an integer of 0 to 8, provided that (p+q) represents an integer of 3 to 10; r represents an integer of 0 to 100; and R represents a hydrogen atom, a methyl group, a fluorine atom or a trifluoromethyl group.
