Abstract
Provided is a multi-layer coating film including a base film and an infrared-reflective film, wherein the infrared-reflective film includes a scale-like infrared-reflective pigment and a resin; the pigment includes a layered body that has dielectric layers and a metal 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 layer is made from a silver compound; a film thickness of the metal layer is 5 to 15 nm; a film thickness of the dielectric layer is ((Nλ)/(4r))±20 nm (N is 1, 2 or 3, wavelength λ is 250 to 980 nm, r is the refractive index of the dielectric layer); the infrared reflectance R1 of the base film is smaller than 80% and is smaller than the infrared reflectance R2 of the infrared-reflective film.
