Multilayer metallic coating is formed on a substrate by applying a base coating composition containing a metallic pigment, applying a clear top coating composition on the base coating wet-on-wet, and curing both coatings simultaneously. The coating compositions contain a film-forming polymer having a plurality of crosslinkable function groups, a crosslinker an organic liquid diluent, internally crosslinked polymer microparticles and an organic acid catalyst masked with an organic base capable of accelerating the crosslinking reaction between the film-forming polymer and the crosslinker. |
