Zusammenfassung:	Powder coatings and a powder composition having a valuable combination of characteristics are described, composed of a homogeneous mixture of between 1.9 and 9.0 wt. % of a diglycidyl phthalate and between 91.0 and 98.1 wt. % of a polyester, wherein said polyester has (a) an acid number between 10 and 30 mg KOH/g, (b) a hydroxyl number less than 15 mg KOH/g, (c) a theoretical number-average molecular weight between 3,750 and 12,500 and (d) a glass transition temperature between 48 DEG and 85 DEG C.
