    Abstract: The use of crystalline zeolitic molecular sieves in electrically conductive backing paper provides improved results in a conventional electrostatic printing process. The molecular sieves are employed in the backing paper in an amount sufficient to impart an electrical resistivity of less than 1 X 1012 ohm-cm over the range of relative humidity of from 5 to 90%.
