Layered body

A method for forming a multilayer coating film, the method comprising the following steps (1) to (3):

• (1) applying a metallic base paint to a substrate to form a metallic base coating film;
• (2) applying a transparent colored paint to the metallic base coating film to form a transparent colored coating film;
• and
• (3) heating the metallic base coating film formed in step (1) and the transparent colored coating film formed in step (2) to separately or simultaneously cure the coating films,
• wherein the metallic base paint has a solids content of 1 to 20 mass % and comprises water, an aluminum pigment, a light-scattering component, a surface adjusting agent, and a rheology control agent, the aluminum pigment being present in an amount of 0.2 to 6 parts by mass, on a solids basis, and the light-scattering component being present in an amount of 0.1 to parts by mass, on a solids basis, based on 100 parts by mass of the metallic base paint;
• and
• the transparent colored paint comprises a resin component, a curing agent, and a color pigment, the color pigment being present in an amount of 0.5 to 10 parts by mass, based on 100 parts by mass of the resin solids content in the transparent colored paint.
