Abstract
An electronic device has a touch screen comprising a transparent substrate having a first supporting side and an opposing second supporting side. The first supporting side of the touch screen has at least one electrically-conductive pattern, and a dry outermost polymeric coating disposed over at least part but not all of the electrically-conductive metal pattern. The dry polymeric coating has a dry thickness of less than 5 μm, an integrated transmittance of at least 80%, and a non-crosslinked thermoplastic polymer having a glass transition temperature (Tg) that is equal to or greater than 65° C.
