摘要： A process for preparing a device containing a continuous, semi-transparent conductive layer including providing a substrate, applying to the substrate a coating containing a dispersion of conductive particles having an average particle size less than about 1 micrometer and having an acidic or neutral outer surface in a basic solution containing a film forming polymer dissolved in a solvent, and drying the coating to remove the solvent and form the continuous, semi-transparent conductive layer. The article prepared by this process may be used in an electrophotographic imaging process.
