Open the CIPO recordAbstract From the Canadian patent
Photoresponsive imaging members comprised of hole transporting polysilylene compounds with a single peak molecular weight distribution, and wherein the polysilylenes selected have excluded therefrom molecular weight fractions of less than 50,000 thereby enabling for example, the resulting imaging members to be substantially resistant to liquid ink developer compositions for an extended number of imaging cycles when these members are incorporated into electrostatographic imaging devices.
