The invention provides a transparent paint composition of a multilayer coating film, which is not easy to be affected by the roughness of the surface of the bottom material, the flatness and the DOI performance are excellent, when the coated object is sequentially coated by a first water coloration paint, a second water coloration paint, and a transparent coating, and then is solidified together to form the multi-layer coating film, and the multi-layer coating forming method. The paint composition comprises the acrylic resin (A) containing the hydroxyl, the melamine resin (B), and the polyhydric alcohols (C) having the special number-average molar mass in a range from 300-1500. The paint composition can be used as the transparent paint, and the coated object is sequentially coated by the first water coloration paint, the second water coloration paint, and the transparent coating, which are heated and solidified together to form the multi-layer coating. |
