Abstract: Ultraviolet absorbing hardcoat and precursor therefore comprising a binder and nanoparticles in a range from 1 to 90 wt. %, based on the total weight of the hardcoat, wherein at least a portion of the ZnO nanoparticles are surface modified with L-lysine and have a silica coating thereon. Hardcoats described herein are useful, for example, for optical displays (e.g., cathode ray tube (CRT) and light emitting diode (LED) displays), personal digital assistants (PDAs), cell phones, liquid crystal display (LCD) panels, touch-sensitive screens, removable computer screens, window film, and goggles.
