Abstract
Provided is a method for forming a multilayer coating film including the following steps (1) to (4): (1) applying a base paint (X) to a substrate to form a base coating film; (2) applying a specific effect pigment dispersion (Y) to the base coating film formed in step (1) to form an effect coating film with a specific dry film thickness; (3) applying a clear paint (Z) to the effect coating film formed in step (2) to form a clear coating film; and (4) heating the uncured base coating film, the uncured effect coating film, and the uncured clear coating film formed in steps (1) to (3) to simultaneously cure these three coating films.
