Abstract

Thermal imaging donors are useful for thermal transfer patterning of a metal layer 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. These include electromagnetic interference shields and touchpad sensors.
