Disclosed is an organic-inorganic hybrid composition. The organic-inorganic hybrid composition includes a curable resin and inorganic particles dispersed in the curable resin. The inorganic particle has a core-shell structure composed of a core containing titanium and barium, and a shell containing at least one selected from zirconium, aluminum and chromium. According to this organic-inorganic hybrid composition, a liquid-phase refractive index of the composition can be improved, and as a result, luminance and light transmittance can be improved in an optical member using the same.
Disclosed is a brightness enhancing film composition comprising a multifunctional (meth)acrylate, a substituted or unsubstituted naphthyl (meth)acrylate monomer, an arylether (meth)acrylate and an optional polymerization initiator. The composition was found to efficiently cure under typical conditions employed for the rapid, continuous production of cured, coated films. Such cured compositions exhibit excellent relative degree of cure under a variety of processing conditions. Disclosed also are articles comprising the brightness enhancing film composition comprising a multifunctional (meth)acrylate, a substituted or unsubstituted naphthyl (meth)acrylate monomer, an arylether (meth)acrylate and an optional polymerization initiator. The article may be a multilayer article comprising a substrate.
