Title:
INFRARED-REFLECTIVE PIGMENT AND INFRARED-REFLECTIVE COATING COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2016/006664
Kind Code:
A1
Abstract:
To provide an infrared-reflective pigment and infrared-reflective coating composition provided with both high infrared-light reflecting properties and high visible-light transparency. Provided is a flake-shaped infrared-reflective pigment, the infrared-reflective pigment 1 characterized by being provided with a layered body 13 having at least one metal thin-film layer 11 and at least two transparent dielectric layers 12, the film thickness of the dielectric layer 12 being (an integer multiple of λ/4n) ± 10 nm, where λ is the wavelength of incident light in a visible-light peripheral region and n is the refractive index of the dielectric layer 12. Also provided is an infrared-reflective coating composition containing the infrared-reflective pigment 1.
