  • Publication number: 20240210597
    Abstract: An antiglare film includes a substrate having a sheet-like shape, a lower hard coat layer disposed overlapping the substrate, and an upper hard coat layer disposed layered on a side of the lower hard coat layer opposite to a side of the substrate. A thickness of the lower hard coat layer is a value within a range of at least 150% or more of a thickness of the upper hard coat layer.

  • Publication number: 20230373192
    Abstract: An anti-glare film including a light reflectance of 3.8% or less and a haze of 40% or greater. A 60° gloss of the anti-glare film may be 15% or less. The anti-glare film includes a transparent substrate layer, and an anti-glare layer formed on at least one surface of the transparent substrate layer. The anti-glare layer may be a cured product of a curable composition including one or more types of a polymer component and one or more types of a curable resin precursor component, and in particular, at least two components selected from a polymer component and a curable resin precursor component can be phase separated through liquid phase spinodal decomposition. The anti-glare film has improved anti-reflection properties.

  • Publication number: 20200257161
    Abstract: An anti-glare film is prepared which have an absolute value of a chromaticity b* of transmitted light being 15 or less and a haze being 30% or greater. In this anti-glare film, the absolute value of the chromaticity b* of transmitted light may be 3 or less and a 60° gloss may be 25% or less. The anti-glare film includes a transparent substrate layer, and an anti-glare layer formed on at least one surface of the transparent substrate layer. The anti-glare layer may be a cured product of a curable composition including one or more types of a polymer component and one or more types of a curable resin precursor component, and in particular, at least two components selected from a polymer component and a curable resin precursor component can be phase separated through liquid phase spinodal decomposition. This anti-glare film has little yellowness and high anti-glare properties.
