Abstract
To provide a powder coating material capable of forming, by one coating, a cured film which has a double-layered structure comprising a cured resin layer and a fluororesin layer and which is excellent in weather resistance, wherein the fluororesin layer is less likely to be peeled for a long period of time; a coated article; and processes for their production. The powder coating material comprises a powder (X) composed of a composition (α) comprising a fluororesin (A) and an ultraviolet absorber (B), and a powder (Y) composed of a composition (β) comprising a thermosetting resin (C) other than a fluororesin, a curing agent (D) and a light stabilizer (E).
