Abstract

The invention provides metal compositions, including silver compositions, and thermal imaging donors prepared with the compositions. The donors are useful for thermal transfer patterning of a metal layers and optionally, a corresponding proximate portion of an additional transfer layer onto a thermal imaging receiver. The compositions are useful for dry fabrication of electronic devices. Also provided are patterned multilayer compositions comprising one or more base film(s), and one or more patterned metal layers, including EMI shields and touchpad sensors.
