Abstract
A multilayer coating film includes a lustrous layer containing a luster material and a blackish coloring agent, and a colored layer containing a reddish coloring agent, and having translucency. A slope of a tangent of a spectrum of a spectral transmittance, defined as an absolute value, of the colored layer at the wavelength of 620 nm is 0.02 nmor more and 0.06 nmor less, the spectral transmittance being obtainable by dividing a spectral reflectance measured for the colored layer stacked on the lustrous layer at the light receiving angle of 15° in the case of the light incident angle of 45°, by a spectral reflectance measured for the lustrous layer from which the colored layer is removed and a surface of which is therefore exposed, at the light receiving angle of 15° in the case of the light incident angle of 45°.
