<p>The invention relates to a powder paint composition comprising: a) a compound comprising hydroxyalkylamide units, b) a stabilizer, and c) a compound capable of reacting with hydroxyalkylamide units, whereby said compound a) comprising hydroxyalkylamide units is a branched condensation polymer containing ester groups, having at least one amide group in the backbone, having at least one hydroxyalkylamide end group and having a weight average molecular mass of at least 800 g/mol and, whereby said stabilizer b) is at least one phenolic anti-oxidant according to Formula (I) wherein R1 is an, optionally substituted, alkyl or cycloalkyl with at least 4 C-atoms, R2 and R3 are identical or different, and can independently of each other be H, or (C1-C18) (cyclo)alkyl radicals, Z is an mono-, bis- or multifunctional organic group, and n=1-4, whereby when n=1, Z contains at least 3 C-atoms or heteroatoms. The invention also relates to the powder coating obtained after curing of the powder paint composition and to wholly and partly coated substrates.</p> |
