An antireflection film comprises a transparent substrate carrying on one surface a polymeric antireflection layer, this antireflection layer having a refractive index at least 0.02 lower than that of the substrate and being formed from a cured polymer comprising repeating units derived from a fluoroalkene, an alkyl acrylate or methacrylate and a polyfunctional acrylate monomer. No inorganic antireflection layer is present between the substrate and the polymeric antireflection layer.
