Abstract: 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.

Abstract: Holographic storage media comprise two substrates and a core between them, the core comprising thermoplastic photopolymer and a titanium or zirconium compound as a high refractive index material. During photopatterning of the storage medium precursor, the titanium or zirconium compound migrates toward the patterned region or the matrix region surrounding it, causing a refractive index difference which provides optimum holographic properties.
