Abstract

Provided is a method for forming a multilayer coating film giving excellent low temperature impact resistance to a substrate that comprises a metal material and a plastic material. The method for forming a multilayer coating film comprises sequential steps of forming an uncured primer coating film, an uncured first colored coating film, an uncured second colored coating film and an uncured clear coating film on a substrate; and heating the same so as to simultaneously cure these 4 coating films, wherein the aqueous first colored paint and aqueous second colored paint are each a 1-package type paint composition containing a specific hydroxyl group-containing resin and a specific blocked polyisocyanate compound.
