Abstract
A curable 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 or activated methyne groups is disclosed. The curing reaction is catalyzed with a quaternary ammonium, quaternary phosphonium or tertiary sulfonium salt in the presence of finely divided, water-insoluble, inorganic particles having a surface basicity of greater than 1.0 .mu.mol/g which also do not have catalytic activity on the Michael reaction.
