Document Type and Number:
WIPO Patent Application WO/2017/122733
Kind Code:
A1
Abstract:
To provide an infrared reflective coating composition which is capable of forming an infrared reflective coating film that has both high infrared light reflective properties and high visible light transmittance, while exhibiting high transparency.
An infrared reflective coating composition which contains an infrared reflective pigment and a resin component, and wherein: the infrared reflective pigment is provided with a laminate wherein dielectric layers and metal thin film layers are alternately laminated, while having one of the dielectric layers positioned as the outermost surface; the dielectric layers are formed from one or more substances selected from the group consisting of titanium dioxide, niobium pentoxide, cerium oxide, tin-added indium oxide, zinc oxide and tin oxide; the metal thin film layers are formed from a silver compound; the metal thin film layers have film thicknesses of 5-15 nm; if the wavelength λ of incident light in the visible light region and the peripheral region thereof is set to 250-980 nm and r is the refractive index of the dielectric layers, the thicknesses of the dielectric layers are ((Nλ)/(4r)) ± 20 nm (wherein N = 1, 2 or 3); and the ratio of the infrared reflective pigment having a particle diameter of 1 μm or less is 10% by volume or less.
