Title:
ANTIREFLECTION FILM
Document Type and Number:
WIPO Patent Application WO/2019/181165
Kind Code:
A1
Abstract:
An antireflection film (X) has a laminate structure including a base material (11), a hard coat layer (12), and an antireflection layer (13), with a luminous reflectance of 2% or less on the antireflection layer (13) side. When performing a cylindrical mandrel bending test in which a test piece of the antireflection film (X) is bent with the antireflection layer (13) facing inside, the minimum value of a mandrel diameter indicating a flex resistance is 6 mm or less. Along with or instead of this, when performing a cylindrical mandrel bending test in which a test piece of the antireflection film (X) is bent with the antireflection layer (13) facing outside, the minimum value of a mandrel diameter indicating a flex resistance is 10 mm or less. Such an antireflection film is suitable for achieving high antireflection as well as high flex resistance.
