HARDCOAT

摘要

Hardcoat and precursor therefore comprising a binder and a mixture of nanoparticles in a range from 40 wt. % to 95 wt. %, based on the total weight of the hardcoat, wherein l0wt. % to 50 wt. % of the nanoparticles have an average particle diameter in a range from 2 nm to 200 nm and 50 wt. % to 90 wt. % of the nanoparticles have an average particle diameter in a range from 60 nm to 400 nm, and wherein the ratio of average particle diameters of nanoparticles having an average particle diameter in the range from 2 nm to 200 nm to average particle diameters of nanoparticles having an average particle diameter in the range from 60 nm to 400 nm is in a range from 2: 1 to 200: 1. Hardcoat described herein are useful, for example, for optical displays (e.g., cathode ray tube (CRT), light emitting diode (LED) displays), and of devices such as personal digital assistants (PDAs), cell phones, liquid crystal display (LCD) panels, touch- sensitive screens and removable computer screens; and for body of such devices.
