| abstract |
The present invention relates to a composition comprising at least one first (meth) acrylate monomer comprising at least three (meth) acrylate groups and a C 2 - C 4 alkoxy repeat unit wherein the monomers have a molecular weight per (meth) At least one second (meth) acrylate monomer comprising from about 220 to about 375 g / mol and at least one (meth) acrylate group. In one embodiment, the hard coat composition further comprises at least 30% by weight of the solids of the silica nanoparticles having an average particle size in the range of 50 to 150 nm. In another embodiment, the hard coat composition further comprises at least 30% by weight of solids of inorganic oxide nanoparticles having an average particle size in the range of 50 to 150 nm. The present invention also describes articles comprising such cured hard coat compositions, such as protective films, displays and touch screens. |
