Curable high refractive index compositions and articles prepared from them

A method of preparing an article comprising:

• providing a substrate with a first major surface and a second major surface;
• providing a curable composition wherein the curable composition comprises:
• an acrylate of Formula I;
• at least one multifunctional (meth)acrylate with fused aromatic groups, heteroarylene groups, heteroalkylene groups, alkylene groups, or aralkylene groups;
• and
• a photoinitiator;
• wherein the curable composition when disposed and cured has a refractive index of 1.63 or greater at 532 nanometers, is optically transparent, and has a thermal stability such that upon heating for 1 hour at 250° C. has a weight loss of 3.5% or less;
• disposing the curable composition on at least a portion of the second major surface of the substrate to form a curable layer;
• curing the curable layer to form a cured organic layer.
