Abstract

Provided is a method for forming a multilayer coating film, the method being capable of forming a multilayer coating film having excellent chipping resistance, adhesion, and finished appearance. The method for forming a coating film uses a 3-coat and 1-bake system in which a three-layered multilayer coating film obtained by sequentially applying a first coloring paint (X), a second coloring paint (Y), and a clear coating paint (Z) onto an object to be coated is heated and cured at the same time, wherein the first coloring paint (X) and the second coloring paint (Y) contain a hydroxyl group-containing resin, and the clear coating paint (Z) contains a hydroxyl group-containing acrylic resin (a) and an aliphatic triisocyanate compound (b1) having a molecular weight within a specific range.
