Energy-induced dual curable compositions

An article having on at least one surface thereof a polymerizable coating composition comprising a polymeric precursor comprising at least one ethylenically-unsaturated monomer and at least one epoxy monomer different from said ethylenically-unsaturated monomer, and a curing agent comprising

• 1) an organometallic compound having the structure L.sup.1 L.sup.2 L.sup.3 M wherein
• L.sup.1 represents none, or 1 to 12 ligands contributing pi-electrons that can be the same or different ligand selected from substituted and unsubstituted acyclic and cyclic unsaturated compounds and groups and substituted and unsubstituted carbocyclic aromatic and heterocyclic aromatic compounds, each capable of contributing 2 to 12 pi-electrons to the valence shell of M;
• L.sup.2 represents none, or 1 to 24 ligands that can be the same or different contributing an even number of sigma-electrons selected from mono-, di-, and tri-dentate ligands, each donating 2, 4, or 6 sigma-electrons to the valence shell of M;
• L.sup.3 represents none, or 1 to 12 ligands that can be the same or different, each contributing no more than one sigma electron each to the valence shell of each M;
• M represents 1 to 4 of the same or different metal atoms selected from the elements of Periodic Groups IVB, VB, VIB, VIIB, and VIII (CAS version of the Periodic Table);
• with the proviso that said organometallic compounds contain at least one of a metal-metal sigma bond and L.sup.3 ;
• and with the proviso that L.sup.1, L.sup.2, L.sup.3, and M are chosen so as to achieve a stable configuration;
• and
• 2) an onium salt.
