Abstract
A method for forming a multilayer film, including: a step (1) of applying an aqueous two-pack first colored coating material on an automobile outer panel to form an uncured first colored coating film; a step (2) of applying an aqueous one-pack white color coating material on the uncured first colored coating film to form an uncured white coating film; a step (3) of setting the uncured white coating film for 4 minutes or more such that a resultant coating film has a solid content of 50% by mass or more; a step (4) of applying an aqueous one-pack interference color coating material on the uncured white coating film having the solid content of 50% by mass or more to form an uncured interference color coating film; a step (5) of applying a solvent-based two-pack clear coating material on the uncured interference color coating film to form an uncured clear coating film; and a step (6) of heating the coating films formed in the steps (1) to (5) at a temperature of 75° C. or more and to 100° C. or less to simultaneously cure the coating films.
