Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

The invention claimed is: 1. A layered coating film comprising: a lower coat including a first coloring material and aluminum flakes; and an upper coat superposed on the lower coat and including a second coloring material, wherein: 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, the film constituent of the upper coat other than the second coloring material includes an acrylic resin and nanoparticles with a lower refractive index than the acrylic resin, and the film constituent of the lower coat other than the first coloring material and the aluminum flakes includes an acrylic resin. 2. The layered coating film of claim 1 , wherein the film constituent of the lower coat other than the first coloring material further includes a resin and nanoparticles with a higher refractive index than the resin. 3. The layered coating film of claim 1 , wherein a protective coat is provided on the upper coat. 4. The layered coating film of claim 1 , wherein the second coloring material includes the same coloring material as the first coloring material. 5. A coated article comprising: a layered coating film as a coating of the coated article, the layered coating film including: a lower coat including a first coloring material and aluminum flakes; and an upper coat superposed on the lower coat and including a second coloring material, wherein: 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, the film constituent of the upper coat other than the second coloring material includes an acrylic resin and nanoparticles with a lower refractive index than the acrylic resin, and the film constituent of the lower coat other than the first coloring material and the aluminum flakes includes an acrylic resin. 6. The coated article of claim 5 , wherein the film constituent of the lower coat other than the first coloring material further includes a resin and nanoparticles with a higher refractive index than the resin. 7. The coated article of claim 5 , wherein a protective coat is provided on the upper coat. 8. The coated article of claim 5 , wherein the second coloring material includes the same coloring material as the first coloring material.
