Abstract: Imidazole or substituted imidazole is adducted with acrylate ester, an epoxy, or an isocyanate followed by neutralization with lower fatty acid or alkylene or aromatic dicarboxylic acid. The product is a curing agent which is combined with an epoxy resin to form a powder coating.

Abstract: Thermosettable polyester resin compositions, suitable for use in powder coating applications, derived from a dicarboxylic aromatic acid component (e.g., 1,4-benzenedicarboxylic acid), a trihydroxy alkyl component (e.g., 2-ethyl-2-(hydroxymethyl)-1,3-propanediol), a diol component (e.g., 2,2-dimethyl-1,3-propanediol) and a dihydroxy alkyl compound having 4 to 10 carbon atoms in the primary carbon chain between the hydroxyl moieties (e.g., 1,6-hexanediol). Polyesters of the present invention have a number average MW of from about 2,000 to about 6,000, a combined acid and hydroxyl number of about 35 to about 70 milligrams of KOH per gram of polyester, and a glass transition temperature of about 35.degree. C. to about 50.degree. C.
