MICROSTRUCTURED FILM COMPRISING NANOPARTICLES AND MONOMER COMPRISING ALKYLENE OXIDE REPEAT UNITS

摘要

PROBLEM TO BE SOLVED: To provide a microstructured film with high impact resistance.SOLUTION: Presently described are microstructured films comprising nanoparticles and a monomer comprising alkylene oxide repeat units. The microstructured surface comprises the reaction product of a polymerizable composition comprising at least 20 wt.% of inorganic nanoparticles and a non-aromatic multifunctional (meth)acrylate monomer comprising at least three contiguous alkylene oxide repeat units. The multifunctional (meth)acrylate monomer typically comprises two or three (meth)acrylate groups. The alkylene oxide repeat units have the formula -[O-L]-, where each L is independently a C-Calkylene. Also described is a polymerizable resin composition comprising at least 20 wt.% of inorganic nanoparticles having a refractive index of at least 1.68 and a non-aromatic multifunctional (meth)acrylate monomer comprising at least three contiguous alkylene oxide repeat units.SELECTED DRAWING: None
