Abstract
The present invention relates to toner fluid dispersions comprising electrostatically charged colloidal elemental metal particles dispersed in nonconductive organic liquid media of low dielectric constant and containing a charge-inducing surfactant. In other aspects, processes are disclosed for electrophoretically depositing the colloidal elemental metal particles of the toner fluid to produce nonconductive, continuous coatings or patterns and methods of enhancing the coatings or patterns to make them electrically conductive.
