Title:
LAMINATED BODY
Document Type and Number:
WIPO Patent Application WO/2016/175064
Kind Code:
A1
Abstract:
Provided is a laminated body having a surface layer on at least one surface of a supporting base material. The absolute reflectance R1 of the surface layer side of the laminated body, and the absolute reflectance R2 when a layer L having an optical thickness (the value obtained by multiplying the thickness of the layer by the refractive index of the layer) of 72.5 nm is further provided on the surface layer satisfy the following conditions. (A) -1.0% ≤ R1(435.8)-R2(435.8) ≤ 0.5% (B) -1.0% ≤ R1(546.1)-R2(546.1) ≤ 0.5% (C) -1.0% ≤ R1(700.0)-R2(700.0) ≤ 0.5%
R1(X): Absolute reflectance R1 at a wavelength of X nm of the surface layer side of the laminated body.
R2(X): Absolute reflectance R2 at a wavelength of X nm when a layer L having an optical thickness (the value obtained by multiplying the thickness of the layer by the refractive index of the layer) of 72.5 nm is further provided on the surface layer.
Provided is the laminated body which exhibits low reflectance and high transparency, which undergoes little contamination by dirt such as fingerprints, and which is suitable for use in an anti-reflection member or a hard coat member.
