Antireflection film, polarizing plate, and image display device

摘要

An antireflection film comprising a support and a low refractive index layer prepared by coating a coating composition containing the following components: (A) a fluorine-containing polymer, a principal chain of which is made of only carbon atoms and which contains at least one fluorine-containing vinyl monomer polymerization unit and at least one hydroxyl group-containing vinyl monomer polymerization unit, wherein a content of the hydroxyl group-containing vinyl monomer polymerization unit exceeds 20% by mole, provided that the polymer does not have a polysiloxane structure in the principal chain; (B) a crosslinking agent capable of reacting with a hydroxyl group; and (C) a compound containing two or more (meth)acryloyl groups in one molecule thereof.
