Patent ID: 8202634

Claim:
A method of forming a metallic tone glitter paint film comprising: applying a first base metallic paint for providing a sense of glitter with a metallic tone to a base material, the first base metallic paint comprising: an aluminum pigment (A) of average particle diameter D 50 from 13 to 40 μm and average thickness from 0.4 to 2.5 μm; and an aluminum pigment (B) of average particle diameter D 50 from 4 μm to 30 μm and average thickness from 0.02 to less than 0.4 μm, wherein the ratio (A/B) of the masses of the solid fractions of the aluminum pigments (A) and (B) is from 90/10 to 10/90, and the total mass (A+B) of the solid fractions of the aluminum pigments (A) and (B) is from 5 to 50 parts by mass per 100 parts by mass of the resin solid fraction; applying a second base glitter paint to the first base metallic paint wet-on-wet, wherein the first base metallic paint is in an unhardened state, and the second base glitter paint comprising a very small scale-like pigment, or a very small scale-like pigment and an aluminum pigment (C), wherein the very small scale-like pigment is characterized by providing the metallic tone glitter film with a pearlescent gloss; wherein the very small scale-like pigment is selected from the group consisting of metal oxide coated mica pigments, metal oxide coated synthetic mica pigments, metal oxide coated alumina flake pigments, metal oxide coated silica flake pigments, metal oxide coated iron oxides, stainless flakes, metallic titanium flake pigments, plate-like molybdenum sulfide, plate-like bismuth chloride, plate-like iron oxide, cholesteric liquid crystal polymers, and combinations comprising one or more of the foregoing; applying a clear paint to the second base glitter paint wet-on-wet, wherein the second base glitter paint is in an unhardened state; and baking the first base metallic paint, the second base glitter paint, and the clear paint simultaneously at a temperature ranging from room temperature to 160° C., wherein the resulting metallic tone glitter paint film obtains both a pearlescent gloss and a metallic gloss.
