PROBLEM TO BE SOLVED: To provide an antireflection film which does not require a protective film for saponification treatment and has excellent scratch resistance after saponification treatment, without film thickness unevenness or hue unevenness.SOLUTION: The antireflection film comprises, on a transparent support, a hard coat layer, a middle refractive index layer, a high refractive index layer, and a low refractive index layer which are stacked in this order from the bottom. The middle refractive index layer is made of a composition containing (A) organic or inorganic particles with an average primary particle size less than 10 nm, (B) a compound with three or more unsaturated double bonds, and (C) a polymer having a repeating unit corresponding to a monomer represented by the general formula 1 specified in the figure. The content of the polymer (C) is 0.2-2.0 mass% relative to the total solid in the composition, and the content of the organic or inorganic particles (A) is 30-60 mass% relative to the total solid in the composition. |
