Title:
ANTIGLARE FILM, AND FILM HAVING ANTIGLARE PROPERTIES AND LOW REFLECTIVITY
Document Type and Number:
WIPO Patent Application WO/2021/153423
Kind Code:
A1
Abstract:
Provided is an antiglare film in which a reflection reducing layer that is less likely to reduce light reflection performance can be formed. This antiglare film 1 comprises, on at least one surface of a transparent base material layer 2, an antiglare layer 3 which contains a binder resin (A), and organic fine particles (B) and inorganic fine particles (C) dispersed in the binder resin (A). The absolute value of the difference in refractive index between the binder resin (A) and the organic fine particles (B) is 0.005-0.25. The average primary particle diameter of the inorganic fine particles (C) is smaller than the average primary particle diameter of the organic fine particles (B). The arithmetic average roughness (Ra) of the surface of the antiglare layer 3 is in the range of 0.080-0.210 μm. The average interval (Sm) of the irregularities on the surface of the antiglare layer 3 is 0.100-0.200 μm.
