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.
