(57) [Summary] (Problem corrected) [PROBLEMS] To provide a multilayer coating film having excellent impact resistance, particularly chipping resistance, which is comparable to a conventional three-coat film, and without yellowing. Provided is a method for forming a multilayer coating film. SOLUTION: After applying an electrodeposition paint on an object to be coated, Heat curing to form an electrodeposition coating (I), applying an aqueous intermediate coating on the electrodeposition coating to form an uncured intermediate coating, (II) Step (III) of applying an aqueous base paint on the intermediate coating film to form an uncured base coating film, and applying a clear paint on the base coating film to form an uncured clear coating film. A method of forming a film, and a step (V) of simultaneously heating and curing the intermediate coating film, the base coating film and the clear coating film to obtain a multilayer coating film. The electrodeposition paint contains particles A containing the resin (a) and particles B containing the resin (b) and the curing agent. |
