Abstract
A hardcoat composition includes one or more multifunctional (meth)acrylate monomers, and a nanoparticle mixture dispersed within the one or more multifunctional (meth)acrylate monomers. The nanoparticle mixture includes a first population of reactive nanoparticles. The first population of reactive nanoparticles have an average particle diameter in a range from 5 nm to 60 nm, and a second population of non-reactive nanoparticles. The second population of non-reactive nanoparticles have an average particle diameter in a range from 5 nm to 60 nm.
