Abstract
Curable formulations comprising: (a) at least one multifunctional acrylate having a functionality of at least two, (b) at least one mono-acrylate monomer, (c) at least one heteroatom-containing diacrylate, wherein the heteroatom is sulfur or selenium; and (d) a curing agent, have been discovered. The curable formulations show promise as precursors to high refractive index materials suitable for use in light management devices and other optical devices. In addition the novel curable formulations are useful for producing coatings, which may be useful in forming display films, in particular brightness enhancing display films.
