Abstract:
1. A method for forming a conductive circuit comprising the steps of printing a pattern using a conductive ink composition and curing the pattern into a conductive circuit, said conductive ink composition being a substantially solvent-free, liquid, addition curable, conductive circuit-forming ink composition comprising (A) an organopolysiloxane having at least two silicon-bonded alkenyl groups, (B) an organohydrogenpolysiloxane having at least two silicon-bonded hydrogen atoms, (C) conductive particles having an average particle size of at least 5 μm, selected from the group consisting of metal particles, gold-plated particles, silver-plated particles, and copper-plated particles, (D) conductive micro-particles having an average particle size of less than 5 μm, selected from the group consisting of metal particles, gold-plated particles, silver-plated particles, and copper-plated particles, component (D) being present in an amount of at least 1 part by volume per 100 parts by volume of component (A), (E) a thixotropic agent, and (F) a hydrosilylation catalyst.
