A method for making a circuit board having conductive circuit elements with a specific resistivity of less than 10 ohm-cm patterned on a nonconductive substrate, which comprises, 1. printing a radiation curable ink onto the nonconductive substrate to a desired circuit pattern, and 2. effecting the radiation cure of the radiation curable ink, where said radiation curable ink comprises by volume A. from about 10% to 60% of an organic resin binder having a viscosity of from 50 to 10,000 centipoises at 25°C., and B. from about 90% to 40% of a particulated electrically conductive metal containing material substantially free of metal containing material having an aspect ratio of diameter to thickness of a value greater than 20.
