Claim Text:
1. A method of forming a printed pattern on a substrate, comprising depositing a conductive ink comprised of a conductive material, a thermoplastic binder and a solvent, onto the substrate to form a printed pattern, curing the printed pattern at a temperature of from 120° C. to about 140° C. for a sufficient time to remove substantially all solvent from the conductive ink, and fusing the printed pattern by feeding the substrate with the printed pattern thereon through a fusing system operated at a temperature of about 20° C. to about 130° C. above the glass transition temperature of the thermoplastic binder and subjecting the printed pattern to a temperature of at least 120° C. at a minimum to about 140° C., a pressure of from about 50 psi to about 1500 psi, and a feed rate through the fusing system of about 1 m/min to about 100 m/min; wherein the thermoplastic binder comprises polyvinylpyrrolidone and a polyvinylbutyral terpolymer of the formula wherein R
