Abstract
A method of manufacturing a powder coating is provided which does not require a long complicated process, which enables the paint to be manufactured easily and with good conservation of energy, and moreover is free of any danger of gelling during the manufacturing process. The powder coating is manufactured by spray drying a powder coating raw materials solution comprising, as essential constituents, an epoxy group containing acrylic resin (A), a polyvalent carboxylic acid (B), and an organic solvent (C) incorporating an alcohol (C-1) of 2 to 4 carbon atoms, at a temperature at which the epoxy group containing acrylic resin (A) and the polyvalent carboxylic acid (B) undergo no substantial curing reaction.
