PURPOSE:To obtain the antireflection sheet which is improved in an antireflection property by interposing a hardened high-polymer film between a plastic film and an adhesive agent layer. CONSTITUTION:An antireflection film 2 is provided on one surface of the transparent plastic film 1 having 1.61 to 1.69 refractive index and the hardened high-polymer film 3 having 1.55 to 1.62 refractive index is formed on the other surface. While any materials which have 1.55 to 1.62 refractive index after hardening are usable as the material for forming such hardened high-polymer film without any limitation, the formation of the film using a mixture composed of an org. silicone compd. and an org. titanium compd. is most adequate. The reflected light at the boundary between the plastic base material 1 and the adhesive agent layer 4 is decreased in this way without degrading the weatherability and transparency and the effect of preventing reflection is improved. |
