  • Method for forming multilayer coating film
    Publication number: 20030102217
    Abstract: The present invention provides a method for forming a multilayer coating film, comprising: applying a colored cationic electrodeposition coating composition (A) to a metal substrate by electrodeposition; applying a bright pigment-containing clear coating composition (B) to the electrodeposition coating, which is either uncured or thermally cured; and then curing the uncured electrodeposition coating and the clear coating, or the clear coating.
