Beschreibung
Zusammenfassung:	Provided herein is a method of forming a multilayer coating film including coating, onto an object to be coated, a water-based primer coating composition, wet-on-wet coating a first water-based coloring coating composition, wet-on-wet coating a second water-based coloring coating composition, coating a clear coating composition, and simultaneous hardening of the formed multilayer coating film. The water-based primer coating composition contains a water-based polyolefin resin, a water-based polyurethane resin, a curing agent, and conductive carbon. The first and second water-based coloring coating compositions, each, as base resins, contain a core/shell-type emulsion including an acrylic resin core portion and a polyurethane resin shell portion. The clear coating composition contains a hydroxy-group-containing acrylic resin and a polyisocyanate compound.
