An excess of the powder coating composition which is not deposited onto an article to be coated and is recovered in a coating apparatus is dissolved in an aromatic hydrocarbon solvent which dissolves the acrylic resin component and which has a solubility of a curing agent of not more than 1.0 g (curing agent)/100 g (solvent) at 20.degree. C. and the acrylic resin component is recovered from the resin solution. The acrylic resin component thus recovered can be reused as a resin component for coating compositions.
