Patent ID: 7119959

Claim:
A film for optical applications comprising (A) a high refractivity hard coat layer which comprises (a) an antimony-doped tin oxide having a needle shape having an average particle diameter along a major axis of 0.05 to 10 μm and an average aspect ratio of 3 to 100, (b) at least one other metal oxide and (c) a material cured with an ionizing radiation and has a refractive index in a range of 1.60 to 1.75 and a thickness in a range of 2 to 20 μm and (B) a low refractivity layer which has a refractive index in a range of 1.30 to 1.45 and a thickness in a range of 40 to 200 nm, layers (A) and (B) being successively laminated at least on one face of a substrate film.
