    摘要: A powder coating composition comprising:(a) a compound having at least two epoxy groups in the molecule;(b) a compound having at least two carboxyl groups in the molecule; and(c) a compound of the formula: ##STR1## wherein m and n are each an integer of 1-10.sup.5 provided that m.ltoreq.n; R.sub.1 is a residue of a mono or polybasic carboxylic acid; R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are, the same or different, each an unsubstituted or substituted C.sub.1-30 alkyl, C.sub.6-10 cycloalkylalkyl, C.sub.5-8 cycloalkyl, C.sub.6-20 aryl or C.sub.7-30 aralkyl or at least two of them many form together with nitrogen atom a saturated or unsaturated heterocyclic group, said composition being able to be thermoset at low temperature and form a paint film having excellent surface smoothness without browning of the film.
