  • Overcoated charge transporting elements and glassy solid electrolytes
    Patent number: 5874018
    Abstract: Glassy solid electrolytes and charge transporting elements including antistatic elements and charge generating elements. The charge generating element has an electrically conductive layer, a charge generating layer overlying the electrically conductive layer, and a layer of glassy solid electrolyte overlying the electrically conductive layer. The glassy solid electrolyte includes a complex of silsesquioxane and a charge carrier. The complex has a surface resistivity from about 1.times.10.sup.10 to about 1.times.10.sup.17 ohms/sq. The complex has a T.sup.2 -silicon:T.sup.3 -silicon ratio of less than 1 to 1. The complex has a ratio of carbon atoms to silicon atoms of greater than about 1.2 to 1.
    Type: Grant
    Filed: June 25, 1997
    Date of Patent: February 23, 1999
    Assignee: Eastman Kodak Company
