Beschreibung
Zusammenfassung:	The present invention is directed to a method of manufacturing a powder coating composition containing thermosetting resin powders to which surface flake pigments have been bonded, and the method includes a first step of preparing the flake pigments having an average particle size not greater than 10 µm or an average thickness not greater than 60 nm, a second step of obtaining a dispersion by dispersing the flake pigments above in a solvent not dissolving the thermosetting resin powders, a third step of obtaining a mixture by mixing the thermosetting resin powders with the dispersion above, and a fourth step of volatilizing and removing the solvent above while the mixture above is stirred.
