Abstract
Official abstract text for this publication.
The present disclosure provides an article having a substrate having opposing first and second surfaces. A conductor micropattern disposed on the first surface of the substrate. The conductor micropattern has a plurality of traces defining a plurality of cells. The conductor micropattern has an open area fraction greater than 80% and a uniform distribution of trace orientation. Each of the traces has a trace width from 0.5 to 10 micrometer. The conductor micropattern is a tri-layer material comprising in sequence a semi-reflective metal, a transparent layer, and a reflective layer disposed on the transparent layer. The articles are useful in devices such as displays, in particular, touch screen displays useful for mobile hand held devices, tablets and computers. They also find use in antennas and for EMI shields.
