Beschreibung
Zusammenfassung:	A cover article is described herein that includes: a substrate having a primary surface; an optical structure disposed on the primary surface, wherein the optical structure comprises an optical coating and a scratch resistant layer, and wherein the optical coating has an outer surface; and an easy-to-clean (ETC) coating disposed on the outer surface of the optical coating, wherein the ETC coating comprises a fluorine-containing material. The outer surface of the optical coating has a surface roughness (Ra) less than 1.5 nm. The optical structure has a physical thickness of greater than or equal to 500 nm and a maximum hardness of 10 GPa or greater, as measured on the outer surface of the optical coating by a Berkovich Indenter Test along an indentation depth of 50 nm or greater. The scratch resistant layer has a physical thickness from 200 nm to 5000 nm.
