Abstract

An object of the present invention is to provide a method for forming a multilayer coating film, the method making it possible to obtain, with excellent curability at low temperatures and in a short period of time, a multilayer coating film exhibiting an excellent finished appearance. The present invention provides a method for forming a multilayer coating film, wherein a substrate is sequentially coated with at least one layer of one or more base coating compositions, and with one or more clear coating compositions, the method being characterized by utilizing a clear coating composition containing a hydroxy-containing acrylic resin (A) having a hydroxy value in a specific range; a polyisocyanate compound (B) having a viscosity in a specific range; and an organometallic catalyst (C) containing a metallic compound (C1) in which the metal is a member selected from the group consisting of zinc, tin, zirconium, bismuth, lead, cobalt, manganese, titanium, aluminum, and molybdenum, and an amidine compound (C2).
