There is provided a thermosetting powder coatingncomposition comprising (A1) a fluorine-containing copolymer and (B) ancuring agent, in which the copolymer contains, as essential structuralnunits, a fluoroolefin unit, an alkene unit and cyclohexyl vinyl ether unitnand/ or p-tertiary butyl vinyl benzoate unit, has a sum of cyclohexyl vinylnether unit and p-tertiary butyl vinyl benzoate unit of from 5 to 45 % bynmole, has a thermal transition temperature of from 45° to 120°C and hasna crosslinkable reaction group. The thermosetting powder coatingncomposition is excellent in storage stability and provides a coating filmnpossessing a smooth surface and enhanced impact resistance. |
