摘要：
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 30 wt-% solids of silica nanoparticles having an average particle size ranging from 50 to 150 nm. In another embodiment, the hardcoat composition further comprises and at least 30 wt-% solids of inorganic oxide nanoparticles having an average particle size ranging from 50 to 150 nm. Also described are articles, such as protective films, displays, and touch screens comprising such cured hardcoat compositions.
