Abstract
A metal particle liquid toner using PARMOD.TM. technology can be used to electrostatically print high resolution, electrically conductive metal images. The invention comprises a dispersion of metallic toner particles having metal particles combined with a metallo-organic compound, dispersed in an electrically insulating, organic liquid such as Exxon's Isopar with the addition of a charge director to give the proper charge on the toner particles and an appropriate conductivity to the dispersion. This dispersion can be used as a liquid toner to develop an electrostatically produced latent image. The developed image can then be heated to give a conductive image on the printing plate, or it can be transferred to a desirable low or high temperature substrate by an electrostatic gap transfer method and heated to give a conductive image.
