  • Tellurium imaging composition including improved reductant precursor and method
    Patent number: 4698184
    Abstract: Imaging films and film-forming compositions are provided which include a reducible tellurium compound, a reductant precursor, a source of labile hydrogen incorporated in a matrix. The reductant precursors are of the formulae ##STR1## where Y.sub.1 is alkoxy, Y.sub.2 is chloro or alkoxy and Y.sub.3 is hydrogen, chloro or alkoxy.Methods are provided for synthesizing the reductant precursors.
    Type: Grant
    Filed: May 9, 1985
    Date of Patent: October 6, 1987
    Assignee: Energy Conversion Devices, Inc.
    Inventors: Terry T. Yu, Mei-Rong Yen
  • Synthesis method for reductant precursor
    Patent number: 4592867
    Abstract: A synthesis method is provided for the synthesis of quinone compounds of the formula ##STR1## where n is 0-3, Y.sup.1 is alkoxy, Y.sup.2 is alkoxy, chloro, bromo or hydrogen and R' and R" each and independently are hydrogen, alkyl or phenyl. These compounds are useful as reductant precursors in tellurium imaging compositions.
