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.

Abstract: Disclosed herein is a layered coating film comprising a lower coat 30 including a coloring material, an upper coat 20 superposed on the lower coat, and a protective coat 10 superposed on the upper coat. The refractive index of a film constituent of the upper coat is lower than not only that of a film constituent of the lower coat other than the coloring material but also that of a film constituent of the protective coat.

Abstract: A multilayer coating film includes a lower coating film 5 containing a colorant, and an upper coating film 6. If the upper coating film 6 has a refractive index n1 of greater than or equal to 1.2 and less than or equal to 1.5, the ratio n1/n2 of the refractive index n1 of this upper coating film 6 to the refractive index n2 of the lower coating film 5 is set to be greater than or equal to 0.67 and less than or equal to 1. If the upper coating film has a refractive index n1 of greater than or equal to 1.6 and less than or equal to 3.0, the refractive index ratio n1/n2 is set to be greater than 1 and less than or equal to 1.67.

Abstract: This multilayer coating film includes a first coat 5 containing a coloring material and a second coat 6 stacked on the first coat 5. The first coat 5 contains metallic oxide nanoparticles 9 having an ultraviolet interception effect. The second coat 6 contains at least one of the metallic oxide nanoparticles having an ultraviolet interception effect or an organic ultraviolet absorber having an ultraviolet interception effect.
