An object of the present disclosure is to provide a method of forming a multilayer coating film that forms a multilayer coating film with excellent smoothness, distinctness of image, adhesion and water resistance when a plurality of uncured coating films are cured at once, and especially when they are cured at once at low temperature. The method of the present disclosure is as follows. A method of forming a multilayer coating film comprising the following steps 1-1 to 1-4: step 1-1: a step of coating an article to be coated with a primer coating composition (X) and forming an uncured primer coating film on the article to be coated, step 1-2: a step of coating the article to be coated having the uncured primer coating film with an aqueous colored coating composition (Y 1 ) for a base coat, to form an uncured base coat coating film thereover, step 1-3: a step of coating the article to be coated having the uncured primer coating film and uncured base coat coating film, with a clear coating composition (Z), and forming an uncured clear coating film thereover, and step 1-4: a step of curing the uncured primer coating film, the uncured base coat coating film and the uncured clear coating film by heating them. |
