<P>PROBLEM TO BE SOLVED: To provide an antireflection film which has high transparency and excellent mechanical characteristics. <P>SOLUTION: A hard coat layer 2 and an antireflection layer 4 are laminated on a transparent base material film 1 and the antireflection layer 4 is formed of four or more layers of a laminate constituted by alternately laminating a high refractive index material layer and a low refractive index material layer and following conditions are satisfied: (1) in the transparent base material film; a PET film having thickness of 70 to 200 μm, haze of 0.5% or less and total light transmittance of 88% or more is used, (2) in the hard coat layer; a photocurable resin of 3 to 20 μm thickness is used, haze is 0.4% or less, total light transmittance is 89% or more and when a pencil hardness test is performed five times by using 3H pencils with 500 g load, the layer is not injured two or more times, (3) The antireflection layer; total thickness is 100 to 300 nm, and (4) in the antireflection film; haze is 0.4% or less, total light transmittance is 92% or more and luminous reflectance is 0.9% or less. <P>COPYRIGHT: (C)2010,JPO&INPIT |
