Abstract
Antireflective film articles and low refractive index coating compositions are described that comprises a fluorinated free-radically polymerizable polymeric (e.g. intermediate) material. The free-radically polymerizable fluorinated polymeric intermediate comprises 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 other multi-functional free-radically polymerizable material. The total amount of multi-functional materials is preferably at least about 25 wt-%.
