Hybrid light-curing composition

A curable composition comprising:

• 0.1 to 30 wt % of an acid catalyzed urethane (meth)acrylate oligomer having a structure of at least one of Formula (1) or Formula (2) that was made with 0.05 to 6 wt % of an acid catalyst based on the total weight of the urethane (meth)acrylate oligomer:
• A-D-(PD)n-A (1)
• A-(PD)n-P-A (2)
• wherein each A independently is a monohydroxy functional (meth)acrylate group;
• each D independently is derived from a di- or tri-functional isocyanate group;
• each P independently is derived from a polyol having a weight average molecular weight of 50 to 12,000 Daltons based on polystyrene standards;
• and n is 10 to 100;
• 20 to 98 wt % of a cyanoacrylate monomer;
• 0.005 to 4 wt % of a metallocene compound;
• 0.001 to 1 wt % of a free radical polymerization inhibitor;
• and
• 0.01 to 0.1 wt % of an acidic anionic polymerization inhibitor.

A method of making a cured composition comprising:

• curing a curable composition by exposing it to light to form the cured composition;
• wherein the curable composition comprises
• an acid catalyzed urethane (meth)acrylate oligomer comprising an acid catalyst;
• a cyanoacrylate monomer;
• a metallocene compound;
• a free radical polymerization inhibitor;
• and
• an acidic anionic polymerization inhibitor.
