Abstract
The present invention is directed to catalytic compositions and to curable compositions containing them. Catalytic compositions of the present invention consist essentially of: (i) a metal compound; and (ii) a compound different from (i) that catalyzes an addition reaction between an ethylenically unsaturated compound and a thiol, wherein said catalytic composition is essentially free of vanadium compounds. Curable compositions according to the present invention comprise: (a) a polyene, (b) a polythiol, and (c) a catalytic component, which consists of the afore-mentioned catalytic composition.
