It is an object of the present invention to provide a method for forming a composite coating film having excellent appearance and excellent anti-chipping properties when the intermediate paint and the upper paint are coated on a substrate in a wet-wet manner. Wet-wet coatings are aliphatic diisocyanate compounds (a), melamine resins (b), hexamethylene diisocyanate compounds (c) blocked with compounds having active methylene groups, non-aqueous dispersion acrylic resins having a core-shell structure (d ) And flake pigment (e), and urethane-modified polyester resins obtained by hydroxyl group-containing polyester resins obtained by polycondensation of acid components and polyhydric alcohols containing at least 80 mol% of isophthalic acid. It is carried out using one intermediate paint. |
