Abstract
An article including a laminate having a substrate and an ultra-thin cover glass layer bonded to atop surface of the substrate. The ultra-thin cover glass layer has a thickness in the range of 1 micron to 49 microns. The ultra-thin cover glass layer is bonded to the top surface of the substrate with an optically transparent adhesive layer having a thickness in the range of 5 microns to 50 microns.
Claims16
An article comprising:
- a laminate comprising:
- a substrate;
- a cover glass layer bonded to a top surface of the substrate, the cover glass layer comprising a thickness in a range of 1 micron to 30 microns;
- and
- an optically transparent adhesive layer comprising a thickness in a range of 5 microns to 50 microns that bonds a bottom surface of the cover glass layer to the top surface of the substrate,
- wherein the cover glass layer comprises an alkali-containing aluminosilicate glass comprising SnO2 at a mol % of 0.08 mol % or less,
- wherein the laminate achieves a bend radius of 3 mm, and
- wherein the laminate comprises an impact resistance defined by the capability of the cover glass layer to avoid failure at a puncture load of 2.25 kilograms-force or more in a Puncture Test.
