METHOD FOR FORMING MULTILAYER COATED FILM
First Claim
1. A method for forming a multilayer coated film on an object to be coated, the object to be coated having undergone electrodeposition coating and intermediate coating, the method comprising the following steps (1) to (3):
- step (1);
applying a first colored coating material to the object, thereby forming a first colored coated film, the first colored coating material containing an iron-oxide-coated aluminum pigment and a quinacridone pigment and giving a cured coated film which, when having a thickness of 10 μ
m, has a light reflectance in a range of 30% to 35% at wavelengths of 650 nm to 700 nm and has a light reflectance in a range of 15% or less at wavelengths of 410 nm to 440 nm and at wavelengths of 510 nm to 590 nm,step (2);
applying a second colored coating material to the first colored coated film, thereby forming a second colored coated film, the second colored coating material containing a perylene pigment and giving a cured coated film which, when having a thickness of 7 μ
m, has a hue in a range of 35°
±
5°
in terms of hue angle h according to L*C*h color system chromaticity diagram, andstep (3);
applying a clear coating material to the second colored coated film, thereby forming a clear coated film,wherein a color difference AF between the first colored coated film and the multilayer coated film obtained by the steps (1) to (3) is in a range of 20 to 30.

Abstract
A method for forming a multilayer coated film on an object includes steps (1) to (3) below. A first colored coating material is applied to the object, thereby forming a first colored coated film (step (1)). The first colored coating material includes an iron-oxide-coated aluminum pigment and a quinacridone pigment and has a light reflectance property at specific wavelengths. A second colored coating material is applied to the first colored coated film, thereby forming a second colored coated film (step (2)). The second colored coating material includes a perylene pigment and has a specific hue. A clear coating material is applied to the second colored coated film (step (3)). A color difference ΔE between the first colored coated film and the multilayer coated film is in a range of 20 to 30.
