US Patent 7569160 Electrically conductive UV-curable ink

An ultraviolet or electron beam curable conductive material for use in the electronics industry. The conductive material has a low viscosity and is capable of application to a substrate by high speed printing techniques such as flexography and rotogravure and provides high electrical conductivity following cure. The conductive material comprises one or more oligomers, one or more acrylate carriers, one or more reactive monomers such as vinyl ether, conductive filler and one or more photoinitiators. Optional additional ingredients, such as diluents, dispersants, etc. may be added as desired.
