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. |
