Abstract
An economic, optically transmissive, stain and ink repellent, durable low refractive index fluoropolymer composition for use in an antireflection film or coupled to an optical display. In one aspect of the invention, the composition is formed from the reaction product of a fluoropolymer or reactive fluoropolymer, an amino silane ester coupling agent or ester equivalent, a multi-olefinic crosslinker, and optional surface modified inorganic particles or sol gel precursors.
