Abstract
A method for forming a multilayer coating film comprising the steps of: (1) applying a base paint (X) to a substrate to form a base coating film, (2) applying an effect pigment dispersion (Y) to the base coating film formed in step (1) to form an effect coating film, (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 thereby simultaneously cure these three coating films; wherein the effect pigment dispersion (Y) contains water, a black pigment (A), a vapor deposition metal flake pigment (B), and a rheology control agent (C).
