Zusammenfassung:Glass articles having a thin glass layer and a top optically transparent polymeric hard-coat layer disposed on a top surface of the thin glass layer. The top optically transparent polymeric hard-coat layer may have a thickness in a range of 0.1 microns to 200 microns and a pencil hardness of 6H or more, when the pencil hardness is measured with the optically transparent polymeric hard-coat layer disposed on the top surface of the glass layer. The glass articles avoid ejection of glass shard particles from the glass article upon bending to a failure during a static two-point bend test.
