摘要:
A glass article including an ultra-thin glass layer and an optically transparent polymeric hard-coat layer having a pencil hardness of 8H or more bonded to the ultra-thin glass layer. The optically transparent polymer hard-coat layer may include an organic polymer material or an aliphatic or aromatic hexafunctional urethane acrylate. In some embodiments, the glass article may have an impact resistance defined by the capability of the glass article to avoid failure at a pen drop height that is 2 times or more than that of a control pen drop height of the ultra-thin glass layer without the optically transparent polymeric hard-coat layer, where the pen drop height and the control pen drop height are measured according to the Pen Drop Test. In some embodiments, the glass article may survive a bend radius of 5 mm or less.
