Beschreibung
Zusammenfassung:	The present invention provides powder compositions for making coatings or films comprising one or more film-forming polymer or resin and one or more beta-hydroxyalkyl amide curing agent chosen from beta-hydroxyalkyl amide curing agents made from the reaction of one or more lactone or lactide with one or more alkanolamine compound containing one or more beta-aminoalcohol, oligomeric beta-hydroxyalkyl amide curing agents made from the reaction of one or more mixture of aromatic anyhydride with aliphatic anhydride with one or more alkanolamine compound containing one or more beta-aminoalcohol, mixtures thereof, and mixtures thereof with one or more tetrafunctional beta-hydroxyalkyl amide curing agent. The present invention enables the reduction of defects in coatings and films, especially in the case of coatings and films 75 mum or thicker, and, further, provides coating powders that are less expensive than coating powders that are cured solely with tetrafunctional beta-hydroxyalkyl amides.
