ABSTRACT:
A 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, activated methyne or hydroxyl groups is disclosed. The curing reaction is catalyzed with a quaternary ammonium, quaternary phosphonium or tertiary sulfonium salt in the presence of an epoxy compound independently added to the composition or covalently attacted to either component (a) or component (b).
