More Information
Summary:Disclosed herein is an optical article having: (a) a light transmissive substrate; (b) a hardcoat layer disposed on the light transmissive substrate and including a (meth)acrylate-functionalized metal oxide having an average particle size of less than about 100 nm, and a multifunctional (meth)acrylate monomer; and (c) a fluorochemical surface layer disposed on the hardcoat layer opposite the light transmissive substrate and including a fluorinated (meth)acryl monomer, a non-fluorinated crosslinking agent, and from about 25 to about 60 wt.% of conducting metal oxide nanoparticles, wherein the fluorochemical surface layer exhibits iittle or no color change with respect to the fluorochemical surface layer without the nanoparticles.
