ABSTRACT:
A one-component, thermosetting resin composition curable through a Michael reaction between (a) a component having a plurality of .alpha., .beta.-unsaturated carbonyl groups and (b) a component having a plurality of activated methylene of activated methyne groups is disclosed. The curing reaction is catalyzed with a quaternary ammonium, quaternary phosphonium or tertiary sulfonium salt in the presence of a five-membered cyclic carbonate compound independently added to the composition or covalently attached to either component (a) or component (b).
