Abstract:
Presently described are hardcoat compositions comprising at least one first (meth)acrylate monomer comprising at least three (meth)acrylate groups and C2-C4 alkoxy repeat units wherein the monomer has a molecular weight per (meth)acrylate group ranging from about 220 to 375 g/mole and at least one second (meth)acrylate monomer comprising at least three (meth)acrylate groups. In one embodiment, the hardcoat composition further comprises and at least 50 wt-% solids of silica nanoparticles. Also described are articles, such as protective films, displays, and touch screens comprising such cured hardcoat compositions.
