Title:
ANTI-GLARE FILM, METHOD FOR PRODUCING SAME, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/225130
Kind Code:
A1
Abstract:
Provided is an anti-glare film having an anti-glare layer on the surface thereof, wherein the concavo-convex shape of the surface of the anti-glare layer is adjusted to satisfy two or more of properties (1)-(3) below. (1) The arithmetic mean roughness Ra is 0.05-0.25 µm. (2) The average length RSm of profile curve elements is 5-25 µm. (3) The maximum cross-sectional height Rt of the profile curve is 0.1-1 µm. Also, the haze of the anti-glare film is adjusted to 1-60% and the 60° gloss of the surface of the anti-glare layer is adjusted to 0.1-70%. In the anti-glare film, the dynamic friction coefficient on the surface of the anti-glare layer may be 3 or less as measured under the conditions of a load of 0.2 N, a moving speed of 50 mm/sec, and an effective measurement distance of 50 mm using a surface probe having artificial skin attached thereto. This anti-glare film has a surface satisfying both finger slipperiness and scratch resistance.
