Method of forming multilayer coating film

Abstract

A method of forming a multilayer film including an intermediate forming an uncured intermediate coating film by applying an intermediate coat containing a photoluminescent pigment directly on top of an electrodeposited coating film formed on an object to be coated, forming an uncured base coating film by applying a base coating composition containing a colored pigment on the uncured intermediate coating film, forming an uncured clear coating film by applying a clear coating composition on the uncured base coating film, and simultaneously baking and curing the uncured intermediate coating film, uncured base coating film, and uncured clear coating film. The photoluminescent pigment in the intermediate coat is a thin-film shape having a volume-average particle diameter (D50) of 5-20 μm and an average thickness of 0.01-0.3 μm.
