WIPO Patent Application WO/2022/230789
Kind Code:
A1
Abstract:
Through the present invention, it is possible to provide an anti-reflective film having a substrate layer including a thermoplastic resin, a hard coat layer that is a hardened coating film layer on at least one surface of the substrate layer, and a low-refractive-index layer having a refractive index at least 0.05 lower than the refractive index of the hard coat layer in the stated order, wherein the low-refractive-index layer has a thickness of 70-130 nm and contains a fluorine-containing leveling agent and a silicon-containing slipping agent, the surface roughness of the surface of the low-refractive-index layer is 5.0 nm or less, the intensity ratio I(Si)/I(F) of silicon and fluorine in the surface of the low-refractive-index layer is 0.8 to 3.2, and the luminous reflectance of the anti-reflective film is 3.0% or less.
