ABSTRACT:
A radiation (UV or E-beam) curable hardcoat composition formed of a mixture of colloidal silica and hydrolyzed silica acrylate, an acrylic monomer and a photoinitiator is disclosed. Additives including a hindered amine light stabilizer, a fluoroacrylate and alkyl acrylate are employed to improve cure, clarity and hardness. A diphenyl (2,4,6-trimethyl(benzoyl) phosphine oxide UV initiator causes effective out of focus curing.
