Title:
LAYERED FILM HAVING ANTIREFLECTION FUNCTION AND INFRARED-SHIELDING FUNCTION
Document Type and Number:
WIPO Patent Application WO/2018/123411
Kind Code:
A1
Abstract:
The present invention relates to a layered film having an antireflection function and an infrared-shielding function. The present invention is a layered film having a heat-ray shielding layer and a low-refractive-index layer in this order on at least one surface of a resin film, wherein the difference (Rh – Rf) of the refractive index (Rh) of the heat-ray shielding layer and the refractive index (Rf) of the resin film is -0.1 to 0.1, the difference (Rh – RL) of the refractive index (Rh) of the heat-ray shielding layer and the refractive index (RL) of the low-refractive-index layer is 0.05 or greater, and the refractive index (RL) of the low-refractive-index layer is 1.2 to 1.45. The thickness of the heat-ray shielding layer may be 0.1 to 5 µm. The visible-light transmittance of the layered film may be 88% or greater.
