Powder coating resins and coatings made using the powder coating resins are described. The powder coating resins are based on the use of C.sub.12 to C.sub.23 diacids. The C.sub.12 to C.sub.23 diacids are reacted with a reactant having an alcohol functionality and an amine functionality to form a carboxylic acid terminated polymer having ester and amide functionality. Alternatively, the C.sub.12 to C.sub.23 diacids are reacted with a reactant having an alcohol functionality and an amine functionality to form an intermediate polyol, which is then reacted with acetoacetic acid or an ester thereof to form an acetoacetate-terminated polymer.
