Abstract: FF properties of a multilayer coating film configured to exhibit a red color through a lustrous layer (14) and a translucent colored layer (15) are improved to achieve a metallic textured color having a high-quality color tone. The lustrous layer (14) is configured such that Y(10°) is 50 or more and 950 or less and that Y(25°) is 0.05 or more and 0.35 or less times the Y(10°), where Y(10°) represents a Y value, of an XYZ color system, of reflected light measured at a light receiving angle of 10° and Y(25°) represents a Y value of the reflected light measured at the light receiving angle of 25° in a case where a light incident angle is 45°. An inclination of a tangent to the spectrum of the spectral transmittance of the colored layer (15) at the wavelength of 620 nm is 0.012 nm−1 or more and 0.03 nm−1 or less, defined as an absolute value.

Abstract: FF properties of a multilayer coating film configured to exhibit a warm color through a lustrous layer (14) and a translucent colored layer (15) are improved to achieve a metallic textured color having a high-quality color tone. The lustrous layer (14) contains, in a mixed state, a high-reflection flake (21) having a visible light reflectance of 90% or more and a low-reflection flake (22) having a visible light reflectance that is half (i.e., ½) or smaller than the visible light reflectance of the high-reflection flake (21) as the luster material. When both of the high-reflection flake (21) and the low-reflection flake (22) are projected on a bottom of the lustrous layer (14), a ratio of a projected area of the flakes (21) and (22) on the bottom of the lustrous layer (14) is 100%.

The lustrous layer (14) is configured such that Y(10°) is 50 or more and 950 or less and that Y(25°) is 0.05 or more and 0.35 or less times the Y(10°), where Y(10°) represents a Y value, of an XYZ color system, of reflected light measured at a light receiving angle of 10° and Y(25°) represents a Y value of the reflected light measured at the light receiving angle of 25° in a case where a light incident angle is 45°. A concentration C of a warm color pigment of the colored layer (15) is 1% by mass or more and 17% by mass or less.
