PROBLEM TO BE SOLVED: To obtain a water-based metallic coating material capable of forming a metallic coating film of good design with favorable glitter feeling in a double- layer coating film composed of the metallic coating film and a clear coating film formed by 2-coat-1-bake system, wherein a metallic pigment in the metallic coating film is not intermingled with the clear coating film as the upper layer, and to provide a method for forming such a double-layer coating film by the 2-coat-1-bake system (2C1B) using the water-based metallic coating material. SOLUTION: The water-based metallic coating material comprises (A) a thermosetting resin composition, (B) the metallic pigment, (C) infusible crosslinked resin particles 30-130°C in glass transition temperature and (D) a metal silicate. The method for forming the double-layer coating film by the 2C1B comprises the steps of coating a substrate with the water-based metallic coating material, coating the resulting uncured coating surface with a clear coating material, preferably a high-solid one, and then heating to subject both the coating films to simultaneous crosslinking curing.
