[PROBLEMS] To provide a novel powder coating composition. Wherein, for example, R 1 represents an acyl group, R 2 , R 3 and R 4 represent a hydrogen atom or a lower alkyl, especially a tert-alkyl group, and A represents a lower alkylene group, and n represents 1 or 2 Represents A powder coating composition comprising at least one compound represented by the formula (1): The use of this stabilized powder coating composition reduces coating coloration during thermal curing, especially gas oven curing. |
