An object to be attained by the present invention is to provide a method for forming a multilayer coating film having excellent smoothness, distinctness of image, water resistance, adhesion, and popping resistance; moreover, the multilayer coating film has excellent water resistance and adhesion, even when the coating compositions are applied after being stored for a fixed period of time. The present invention provides a method for forming a multilayer coating film comprising applying an aqueous first colored coating composition and a second colored coating composition to a substrate in this order, and heating to simultaneously cure the aqueous first colored coating film and the second colored coating film, wherein the aqueous first colored coating composition comprises an acrylic modified polyester resin and a blocked polyisocyanate compound having a specific blocked isocyanate group. |
