Abstract
Provided is a method for forming a multilayer coating film, comprising simultaneously curing an uncured base coating film, an uncured effect coating film, and an uncured clear coating film. In this method, an effect pigment dispersion (Y) that forms the effect coating film contains water, a surface adjusting agent (A), a flake-effect pigment (B), and a rheology control agent (C), and has a solids content of 0.5 to 10 mass %.
Claims10
A method for forming a multilayer coating film by sequentially performing the following steps (1) to (5):
- (1) applying a colored paint (W) to a substrate, followed by heating, to form a colored coating film,
- (2) applying a base paint (X) to the colored coating film formed in step (1) to form a base coating film,
- (3) applying an effect pigment dispersion (Y) to the base coating film formed in step (2) to form an effect coating film,
- (4) applying a clear paint (Z) to the effect coating film formed in step (3) to form a clear coating film, and
- (5) heating the uncured base coating film, the uncured effect coating film, and the uncured clear coating film formed in steps (2) to (4) to thereby simultaneously cure these three coating films;
- wherein the effect pigment dispersion (Y) contains water, a surface adjusting agent (A), a flake-effect pigment (B), and a rheology control agent (C), and has a solids content of 0.5 to 10 mass %.
