Multilayer coating film and coated article

A multilayer coating film, comprising:

• a lustrous layer containing a luster material and formed directly or indirectly on a surface of a coating target;
• and
• a colored layer which is translucent, containing a reddish pigment, and layered on the lustrous layer, wherein
• the lustrous layer contains, as the luster material, high-reflection flakes and low-reflection flakes,
• the high-reflection flakes are aluminum flakes,
• the low-reflection flakes consist of chrome oxide flakes or carbon flakes,
• a mean particle size of the reddish pigment of the colored layer is 2 nm or more and 160 nm or less,
• a concentration of the reddish pigment of the colored layer is 2% by mass or more and 16% by mass or less,
• the lustrous layer further contains a reddish pigment,
• regarding a Y value of an XYZ color system, the Y value being calibrated by a standard white plate, the lustrous layer satisfies the following:
• Y(10°) is 50 or more and 950 or less;
• Y(25°)=k×Y(10°)(where k is a coefficient);
• and
• k is 0.05 or more and 0.35 or less, where Y(10°) represents a Y value of reflected light measured at a light receiving angle of 10° (a tilt angle toward a light source from a specular reflection angle) and Y(25°) represents a Y value of reflected light measured at a light receiving angle of 25° in a case where a light incident angle is 45° (an angle tilted 45 degrees from a normal to a surface of the lustrous layer), and
• an inclination of a tangent to a spectrum of a spectral transmittance, defined as an absolute value, of the colored layer at the wavelength of 620 nm is 0.012 nm−1 or more and 0.03 nm−1 or 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 25° 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 25° in the case of the light incident angle of 45°.
