Abstract:
A hardcoat composition is described comprising urethane (meth)acrylate oligomer having a first functional groups; an acrylic polymer having second functional groups; wherein the first and second functional groups form a hydrogen bond; and silica nanoparticles. The hardcoat composition may be cured by actinic radiation, upon which the acrylic polymer may be removed by solvent extraction. Also described are articles comprising the cured hardcoat described herein disposed on a surface of a substrate and methods of making an article.
