Abstract

Provided is an infrared-reflective coating composition that includes: a scale-like infrared-reflective pigment; and a resin component, wherein the pigment includes a layered body that has dielectric layers and a metal thin film layer layered in an alternate fashion with the dielectric layer on the outermost layer; the dielectric layer is formed from one or more materials such as titanium dioxide; the metal thin film layer is formed from a silver compound; a film thickness of the metal thin film layer is 5 to 15 nm; a film thickness of the dielectric layer is ((Nλ)/(4r))±20 nm (N=1, 2 or 3) wherein wavelength λ of incident light is 250 to 980 nm, and r is a refractive index of the dielectric layer; and a proportion of the infrared-reflective pigment having a particle diameter of 1 μm or smaller is 10% by volume or smaller.
