  • Patent number: 9250361
    Abstract: An antireflection film is provided which includes stacking in order a transparent base material, a first layer, and a second layer whose refractive index is lower than the refractive index of the first layer. The first layer is formed by curing a coating film containing an ionizing radiation curing material, a quaternary ammonium salt material, and a leveling material.

  • Patent number: 8416381
    Abstract: The present invention provides an anti-glare film which has not only <1> sufficient anti-reflection property but also <2> a high level of contrast and <3> strong anti-glare properties and can be applied on a surface of various display devices such as a note PC, a desktop PC and a TV monitor. The anti-glare film of the present invention includes an anti-glare layer which has concavities and convexities on the surface, a haze according to JIS-7105-1981 in the range of 1.0-5.0%, and an average interval between concavities and convexities on the anti-glare layer surface Sm according to JIS-B0601-1994 in the range of 10-150 ?m.

  • Patent number: 8350988
    Abstract: The present invention provides an anti-glare film which has <1> sufficient anti-reflection properties, <2> a high level of contrast and <3> strong antifouling properties. A surface of an anti-glare layer of the anti-glare film of the present invention has a concave-convex structure, an arithmetic mean roughness (Ra) according to JIS B0601-1994 in the range of 0.02-0.2 ?m when a cut-off wavelength (?c) is 0.8 mm, and a surface free energy in the range of 15-25 mN/m. In addition, a haze of the anti-glare layer of the anti-glare film of the present invention is in the range of 1.0-5.0%.
