Patent ID: 8470439

Claim:
An antireflective film comprising a low refractive index layer comprising the reaction product of a polymerizable organic composition comprising: A) a free-radically polymerizable fluorinated polymeric intermediate comprising the reaction product of i) at least one multi-functional free-radically polymerizable material having a fluorine content of at least 25 wt-%, and ii) optionally at least one multi-functional free-radically polymerizable material having a fluorine content ranging from 0 to less than 25 wt-%, wherein the total amount of multi-functional materials is at least about 25 wt-% based on wt-% solids of the polymerizable organic composition; B) at least one fluorinated free-radically polymerizable material; and C) surface modified inorganic nanoparticles; a high refractive index layer coupled to the low refractive index layer wherein the high refractive index layer comprises surface modified inorganic nanoparticles dispersed in a crosslinked organic material.
