Abstract:
1. An antireflective film comprising a low refractive index layer having a static contact angle with water of at least 100° comprising the reaction product of a composition comprising i) at least one free-radically polymerizable material having a fluorine content of at least about 35 wt-%, and ii) at least one fluoropolyether urethane material having a fluorine content ranging from about 10 wt-% to about 30 wt-% fluorine and a free-radically polymerizable end group; and a high refractive index layer having a refractive index of at least 1.60 and a thickness of at least 1 micron coupled to the low refractive index layer wherein the high refractive index layer is selected from an inorganic material having a refractive index of at least 1.60 or a crossliniked organic material comprising surface modified inorganic oxide particles.
