<p>The present invention provides a method for forming a multi-layer coating film, which is characterized by applying a cationic electrocoating on a metal-made material to be coated, heat-curing the resulting electrocoating film, applying, on the heat-cured electrocoating film, a first color base coating having a sublayer-hiding powder, applying, on the resulting coating film without substantially curing the film, a second color base coating having transparency, heating the two films of the first color base coating and the second color base coating to cure them, then applying a clear coating, and heat-curing the resulting clear coating film. According to the present invention, there can be formed a multi-layer coating film superior in finish appearance, aesthetic effect, corrosion resistance, weatherability, chipping resistance, physical properties, etc.</p> |
