Zusammenfassung: | Disclosed are: a method for forming a metallic multi-layered coating film having high luster, high hardness and high adhesion on a metallic material (MM); and a coated article having a coating film produced by the method. Specifically disclosed are: a method for forming a multi-layered coating film, which comprises the steps of: applying a base coat paint (BC) on the surface of an MM; applying a clear coat paint (CC) on the BC; and baking the BC and the CC simultaneously; wherein the BC comprises a melamine resin (MR), a hydroxyl-containing acrylic resin (AR) having a hydroxyl value of 50 to 100 mgKOH/g and a Tg of 50 to 100 DEG C, a cellulose resin (CR) and/or a microgel (MG), and a photoluminescent pigment, in which the ratio of the amount of the AR to the amount of the MR is 50:50 to 90:10 in terms of mass-based solid content and the ratio of the amount of the CR and/or the MG relative to the total solid content of the AR and the MR is 1.0 to 20 mass% in terms of solid content; andwherein the CC comprises |
