Microstructured film comprising nanoparticles and monomers having alkylene oxide repeating units

摘要

Microstructured films comprising nanoparticles and monomers having alkylene oxide repeat units This specification describes a microstructured film having a microstructured surface, such as a brightness enhancement film. The microstructured surface is a reaction product of a polymerizable composition comprising at least 20% by weight of inorganic nanoparticles and a non-aromatic polyfunctional (meth) acrylate monomer having at least 3 consecutive alkylene oxide repeat units. Including things. Multifunctional (meth) acrylate monomers typically contain 2 or 3 (meth) acrylate groups. The alkylene oxide repeat unit has the formula-[OL]-, wherein each L is independently C2-C6 alkylene. A polymerizable resin composition comprising at least 20% by weight of inorganic nanoparticles having a refractive index of at least 1.68 and a non-aromatic polyfunctional (meth) acrylate monomer having at least 3 consecutive alkylene oxide repeating units Things are also described.
