Abstract
A conductive composition consisting essentially of (a) 50-95 wt % finely divided particles of an electrically-conductive material dispersed in (b) a liquid vehicle, for use in the manufacture of an electrically-conductive pattern on a substrate for the use of reducing cross-sectional area and width while retaining conductivity and resistivity.
