Article with hardcoat

Abstract

Article comprising, in order, a substrate, a hardcoat comprising: a binder; and a mixture of nanoparticles in a range from 60 wt. % to 90 wt. %, based on the total weight of the hardcoat, wherein a range from 10 wt. % to 50 wt. % of the nanoparticles comprise a first group of nanoparticles having an average particle diameter in a range from 2 nm to 200 nm, and in a range from 50 wt. % to about 90 wt. % of the nanoparticles comprise a second group of nanoparticles having an average particle diameter in a range from 60 nm to 400 nm, based on the total weight of nanoparticles in the hardcoat, and having a ratio of the average particle size of the first group of nanoparticles to the average particle size of the second group of nanoparticles are in a range from 1:2 to 1:200; a layer comprising SiOxCy, where 0<x<2 and 0<y<1; and a hydrophilic layer. Articles described herein are useful, for example, for optical displays (e.g., cathode ray tubes (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 films, and goggles.
