Patent ID: 8124233

Claim:
An anti-reflection film, which comprises: a low refractive index layer that is formed by curing a coating solution composition comprising: a fluorine-free copolymer containing a constituent having a polysiloxane structure represented by formula (1) in a main chain and a constituent containing a hydroxyl group in a side chain; and a fluorine-containing copolymer: wherein R 11 and R 12 each independently represents a hydrogen atom, an alkyl group or an aryl group; and p represents an integer of from 10 to 500; wherein the fluorine-free copolymer is represented by Formula (2) wherein X represents the constituent containing the polysiloxane structure represented by formula (1): Y represents a polymer unit based on any vinyl monomer which may be constituted by a single component or may be constituted by plural components; R 21 represents a hydrogen atom or a methyl group; L 21 represents a divalent linking group containing —COO—; and x to z each represents a mol fraction (%) of each constituent, with x to z satisfying 10≦x<100, 0≦y≦50, 0<z≦50, and 0<y+z≦90.
