Coating Composition, Optical Film, Antireflective, Film, Polarizing Plate, And Display Device Using The Same

摘要

There is provided a coating composition capable of improving evenness in drying and evenness in airing and causing no impairment of evenness in coating, which is useful for an antireflective film having high uniformity in surface conditions and attaining sufficient antireflection performance and for a polarizing plate and a display device each using such an antireflective film. As the coating composition as mentioned above, a coating composition including a fluoroaliphatic group-containing copolymer that includes a repeating unit corresponding to the fluoroaliphatic group-containing monomer represented by the following formula (1) and a repeating unit corresponding to the monomer represented by the following formula (2) was found: in formula [1], R⁰ represents a hydrogen atom, a halogen atom or a methyl group; L represents a divalent linkage group; and n represents an integer of 1 to 18, and in formula [2], R¹¹ represents a hydrogen atom, a halogen atom or a methyl group; L¹¹ represents a divalent linkage group; and R¹³, R¹⁴ and R¹⁵ each represents a 1-20C linear, branched or cyclic alkyl group which may have a substituent.
