Abstract
A method for forming a multilayer coating film includes applying an aqueous first base coating composition (A) onto a cured electrodeposition coating film, applying an aqueous second base coating composition (B) without preheating, performing preheating, further applying a clear coating composition (C), and simultaneously heat-curing the first base coating film, the second base coating film, and the clear coating film. The aqueous first base coating composition contains a specific aqueous polyester resin, a specific aqueous acrylic resin, a specific aqueous urethane resin and a melamine resin. A breaking energy of a coating film formed of the aqueous first base coating composition and a peel strength between the coating film and the cured electrodeposition coating film are controlled to specific values.
