Title
(EN) METHOD FOR FORMING MULTI-LAYERED COATING FILM
(FR) MÉTHODE DE FORMATION DE FILM DE REVÊTEMENT MULTICOUCHE

Abstract
(EN)
Provided is a novel means for improving the orientation of a scale-like luster pigment in the formation of a multi-layered coating film including a coating film containing the luster pigment. A method for forming a multi-layered coating film, comprising an intermediate coating step of applying a water-based intermediate coating material composition (A) onto the surface of an object of interest to form an uncured water-based intermediate coating film, a first water-based base coating step of applying a first water-based base coating material composition (B) onto the uncured water-based intermediate coating film to form an uncured first water-based base coating film, a second water-based base coating step of applying a second water-based base coating material composition (C) containing a scale-like luster pigment onto the uncured first water-based base coating film to form an uncured second water-based base coating film, a clear coating step of applying a clear coating material composition (D) onto the uncured second water-based base coating film to form an uncured clear coating film, and a curing step of heat-curing the obtained uncured water-based intermediate coating film, the uncured first water-based base coating film, the uncured second water-based base coating film and the uncured clear coating film at one time to form a multi-layered coating film, wherein the solid matter concentration (% by mass) in each of the uncured first water-based base coating film and the uncured second water-based base coating film satisfies a specified requirement.
