Abstract:
1. An antireflective film comprising a light transmissive substrate having a thickness ranging from about 20 to 200 microns a high refractive index layer having a refractive index of at least about 1.60 and a thickness ranging from about 3 to 5 microns disposed on the substrate, wherein the high refractive index layer comprises at least 60 wt-% of inorganic nanoparticles having a refractive index of at least 1.60 dispersed in a crosslinked organic material wherein the crosslinked organic material is the reaction product of a polymerizable resin composition comprising at least one di(meth)acrylate monomer or oligomer comprising at least two aromatic rings and an alkoxylated(meth)acrylate group bonded to each of the two rings; and a low refractive index surface layer, having a refractive index of at least 0.10 less than the high refractive index layer, coupled to the high refractive index layer; wherein the high refractive index layer does not crack when testing according to ISO 1519 using a mandrel size of 6 mm.
