Abstract
An object of the present invention is to provide a powder coating material capable of forming a coating film excellent in weather resistance, whereby formation of color unevenness or pinholes is suppressed. Further, another object of the present invention is to provide a method for producing the powder coating material and a coated article. The powder coating material of the present invention comprises a powder component containing a fluorinated copolymer which has repeating units based on a fluoroolefin and repeating units based on a monomer having no fluorine atom and which has a fluorine content of at least 10 mass %, and a plasticizer-covered luster pigment, wherein the plasticizer has a melting point of from 30 to 200° C. and a molecular weight of from 200 to 1,000 and which has from 1 to 4 ester groups in one molecule.
