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 it 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) phosphate oxide UV initiator causes effective out of focus curing.
本发明公开了一种可辐射(紫外线或电子束)固化的硬涂层组合物,该组合物由胶体二氧化硅和水解丙烯酸二氧化硅、丙烯酸单体和光引发剂的混合物组成。添加剂包括受阻胺光稳定剂、氟丙烯酸酯和丙烯酸烷基酯,用于改善固化、透明度和硬度。一种二苯基(2,4,6-三甲基(苯甲酰基)磷酸酯)氧化物紫外线引发剂可有效地进行非聚焦固化。
