Zusammenfassung:PROBLEM TO BE SOLVED: To provide a powder coating composition providing a coated film having excellent finished appearance, scratch resistance, water resistance and moisture resistance even when the thickness of the coated film is decreased compared to that of the conventionally formed coated film in various kinds of applications. SOLUTION: The powder coating composition contains an epoxy group-containing vinylic copolymer having ≥40°C glass transition temperature, an epoxy group-containing vinylic copolymer having ≤0°C glass transition temperature and having an organosiloxane side chain, and a polybasic carboxylic acid as essential components.
