<p>An electrographic medium for receiving a latent charge image by application of a voltage across it, comprises a paper support bearing a continuous hydrophobic dielectric layer of stearic, palmitic, oleic, cholic, abrietic, lauric or linoleic acid, or the Zn, Ni, Cu, Al, Li, Hg, Sn, Pb, Mn, Fe or Bi salt. The media are inexpansive and have excellent electrographic properties over a wide range of relative humidities up to 95%.</p> |
