Water-based intercoating composition and method of forming multilayered coating film

A water-based intermediate coating composition which contains a water-dispersible polyurethane composition is used. Here, the water-dispersible polyurethane composition is obtained from: a polyisocyanate component containing diisocyanate as an essential component; a polyol component containing polycarbonatediol with an average molecular weight of 500 to 5,000 and carboxyl group-containing diol as essential components; an amine component containing a monoamine compound as an essential component; a carboxyl group-neutralizing component; and water. A three-layered coating film including the water-based intermediate coating, a water-based base coating and a clear coating is formed through a wet-on-wet process on a material onto which an electrodeposited coating film is formed. Thereafter, the three coating films are baked and cured at the same time, thereby forming a multilayer coating film.
