Coatable compositions contain metal-(meth)acrylate hybrid materials that when cured form a metal-polymer hybrid layer with a relatively high refractive index. The curable metal-(meth)acrylate hybrid composition includes a photoinitiator, a polyoxometalate and either a hydroxyl-functional (meth)acrylate or a mixture of hydroxyl-functional (meth)acrylate and aromatic (meth)acrylate. The printable, solvent-free composition, upon curing forms a metal-polymer hybrid layer that is optically transparent and has a refractive index of at least 1.52.
