METHOD FOR FORMING MULTILAYER COATING FILM

WIPO Patent Application WO/2018/074376

A1

The purpose of the present invention is to provide a method for forming a multilayer coating film that can form a multilayer coating film with a superior sense of brightness, high saturation, and a superior sense of depth. Provided is a method for forming a multilayer coating film by applying in this order a first color base coating material, a second color base coating material, and a clear coating material to a base material in a wet-on-wet application. In the method for forming a multilayer coating film, the first color base coating material includes a metal flake pigment and colored pigment, and the metal flake pigment concentration is in a range of 20 – 60 parts by mass to 100 parts by mass of resin solid content included in the first color base coating material, while the coating solid content concentration is in a range of 5 – 15% by mass of the total amount of the first color base coating material. The film thickness of the coating film by the first color base coating material is in a range of 1 – 7 µm on the basis of the solidified coating film. The second color base coating material includes a colored pigment, and the multilayer coating film obtained has a specific range of saturation C* and C*/L* in the L*C*h colorimetric system.
