A step of applying a specific water-based first colored paint (X), water-based second colored paint (Y) and clear paint (Z) on an object containing a metal material and a plastic material, and these three coating films Is a method of forming a multilayer coating film in which the steps of curing at the same time are performed, and a cured coating film having a thickness of 5 μm obtained by applying and curing the aqueous first colored paint (X) at a wavelength of 360 to 420 nm. Provided is a method for forming a multilayer coating film, wherein the average light transmittance is less than 1%. |
