Abstract:
A film for optical applications comprising (A) a hard coat layer which comprises a resin cured by an ionizing radiation and has a thickness in a range of 2 to 20 &mgr;m, (B) a high refractivity layer which comprises a resin cured by an ionizing radiation and at least two metal oxides comprising tin oxide doped with antimony, the high refractivity layer having a refractive index in a range of 1.65 to 1.80 and a thickness in a range of 60 to 160 nm and (C) a low refractivity layer which comprises a siloxane-based polymer, the low refractivity layer having a refractive index in a range of 1.37 to 1.47 and a thickness in a range of 80 to 180 nm, layers (A) to (C) being successively laminated at least on one face of a substrate film.
