However, there is a problem that the hue, lightness and saturation of the mica powder-containing paint may limit the color tone of the colored base paint, and the painting process is complicated. In the above,
Since the mica powder itself does not have a concealing property as a coating film, if a concealing property is imparted by using a coloring pigment in combination, there is a problem that the pearly feeling due to the mica powder is significantly reduced.

リックムラの発生が解消された。The technical effects of the coating method of the present invention are as follows. Excellent design effects by the three-coat two-bake method were achieved by the two-coat one-bake of the present invention in which the steps were shortened. In addition, all the defects of the three-coat two-bake system could be eliminated. Compared to the two coats and one bake, the glitter changes remarkably depending on the viewing angle. In other words, the highlight portion has a metallic tone with excellent glitter, while the shade portion has a solid tone. Excellent repair paintability. In conventional coating systems, spot repair is difficult due to large color changes due to differences in coating conditions. Especially in 3 coats and 2 bake, repair coating becomes more difficult due to the complex color of the colored base and mica base. The method of the present invention did not have such a problem and could improve the repairability. Excellent finish. In the method of the present invention, since the base coat (A) contains a titanium white pigment, the occurrence of metallic unevenness was eliminated.
