A layered coating film according to the present invention includes a lower coatincluding a first coloring material and a bright material, and an upper coatsuperposed 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.

Layered coating film, and coated article

Disclosed herein is a layered coating film comprising a lower coatincluding a coloring material, an upper coatsuperposed on the lower coat, and a protective coatsuperposed 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.

A multilayer coating film includes a lower coating filmcontaining a colorant, and an upper coating film. If the upper coating filmhas 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 filmto the refractive index n2 of the lower coating filmis 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.
