Abstract:
1. 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 the range of 2 to 20 μm, (B) a high refractivity layer I which comprises a resin cured by an ionizing radiation and a metal oxide and has a refractive index in a range of 1.70 to 1.95 and a thickness in a range of 30 to 120 nm, (C) a high refractivity layer II which comprises a resin cured by an ionizing radiation and a metal oxide and has a refractive index in a range of 1.60 to 1.70 and has a thickness in a range of 5 to 70 nm and (D) a low refractivity layer which comprises a siloxane-based polymer and has a refractive index in a range of 1.37 to 1.47 and a thickness in a range of 60 to 180 nm, layers (A) to (D) being successively laminated on at least one face of a substrate film.
