<p>The invention offers methods for forming multilayer coating film excelling in smoothness, distinctness of image, water resistance and chipping resistance, the methods comprising successively applying onto a coating object a water-based first coloring paint and a water-based second coloring paint, and simultaneously heating and curing the resultant first colored coating film and second colored coating film, in which the water-based first coloring paint comprises hydroxy-containing polyester resin, curing agent, and water-dispersible acrylic resin which is obtained by polymerization of a monomer component comprising 30-100 mass % of C5-22 alkyl-containing polymerizable unsaturated monomer and 0-70 mass % of polymerizable unsaturated monomer other than the C5-22 alkyl-containing polymerizable unsaturated monomer.</p> |
