Abstract

The present invention provides a method for forming a multilayer coating film including an intermediate coating film formation step of applying an aqueous intermediate coating composition to an object to be coated to form an uncured intermediate coating film; a base coating film formation step of applying an aqueous base coating composition onto the resulting uncured intermediate coating film to form an uncured base coating film; and a curing step of curing the resulting uncured intermediate coating film and the base coating film by heating.
