Abstract
To provide a production method for obtaining a coated article provided with a coating film having excellent weather resistance by using a powder coating material. A method for producing a coated article, which comprises applying a powder coating material comprising a fluororesin (A), a non-fluororesin (B) and a metallic pigment (C) to the surface of a substrate, and heating the substrate having the powder coating material applied, to a temperature of at least the glass transition temperature of the fluororesin (A) and the non-fluororesin (B), followed by cooling, to form a coating film on the substrate surface, and which is characterized in that the content of the metallic pigment (C) is from 0.7 to 23 mass % to the total amount of the powder coating material, the PCI value of the coating film is at least 6, and the flip-flop value is at least 1.2.
