Abstract
Disclosed is a three coat one bake coating process for forming an intermediate coated film, a base coated film and a clear coated film on an electrodeposition coated film. The electrodeposition coating composition is a lead-free cationic electrodeposition coating composition which has a volatile organic content of 1% by weight or less, a metal ion content of 500 ppm or less, a neutralizing acid amount of 10 to 30 mg equivalent based on 100 g of binder resin solid content. The intermediate coating composition and/or the base coated composition comprises a specific amount of a nonaqueous dispersion resin as a resin component. In the coating process, a baking step is omitted from the conventional intermediate coating process, or from the conventional base coating process.
