Abstract:
    The method of electrophotographically manufacturing a screen assembly on an interior surface of a faceplate panel for a color CRT includes the steps of sequentially coating the surface of the panel with a conductive solution to form a volatilizable organic conductive layer and then overcoating the conductive layer with a photoconductive solution to form a volatilizable organic photoconductive layer. The conductive layer, comprising a quaternary ammonium polyelectrolyte and a surfactant, provides an electrode for the photoconductive layer and has improved electrical and physical properties compared to prior conductive layers.
