Abstract: A metallic base coating film 15 is stacked on a colored base coating film 14 provided on a surface of an article to be coated. While the colored base coating film 14 alone is formed on the surface of the article to be coated, a light reflectance at light receiving angles of 15° and 45° is measured to be 2% or below in a wavelength ranging from 450 nm to 700 nm inclusive. On the metallic base coating film 15 alone, the light reflectance measured at the light receiving angle of 15° ranges from 20% to 50% inclusive in the wavelength ranging from 450 nm to 700 nm inclusive, and the light reflectance measured at the light receiving angle of 45° is 2.5% or below in the wavelength ranging from 450 nm to 700 nm inclusive.

Abstract: The flip-flop properties and the metallic impression are enhanced in a metallic coating. The coating includes a colored base layer formed directly or indirectly on a surface of a coating target, and a bright material-containing layer layered on the colored base layer and containing flaked bright materials and a colorant. The thickness of the bright material-containing layer is 1.5 μm or more and 6 μm or less. When all the bright materials present in the bright material-containing layer are projected on a surface of the bright material-containing layer, an area occupancy of projections of the bright materials with respect to the surface of the bright material-containing layer is 30% or more and 90% or less.

Abstract: The flip-flop properties and the metallic impression are enhanced in a metallic coating. The coating includes a colored base layer formed directly or indirectly on a surface of a coating target, and a bright material-containing layer containing flaked bright materials and a colorant and layered on the colored base layer. With respect to the bright material-containing layer in a state without the colorant, Y(10°) of the XYZ color system is set to be 50 or more and 850 or less, and Y(20°) is set to be equal to k×Y(10°), where k is in a range of 0.2≤k≤0.6 and is determined according to the Y(10°). The colorant concentration of the bright material-containing layer is determined according to k.

Abstract: A layered coating film according to the present invention includes a lower coat 30 including a first coloring material and a bright material, and an upper coat 20 superposed on the lower coat and including a second coloring material. The upper coat and the lower coat have similar colors. The refractive index of a film constituent of the lower coat other than the first coloring material is higher than the refractive index of a film constituent of the upper coat other than the second coloring material.
