  • Xerographic plate having an phthalocyanine pigment interface barrier layer
    Patent number: 4106935
    Abstract: There is disclosed an electrophotographic imaging member comprising a conductive substrate having coated thereover an interfacial barrier layer comprising phthalocyanine in an electrically insulating binder resin which layer is overcoated with a photoconductive layer comprising selenium. The member has substantially panchromatic response. The interfacial barrier layer comprising phthalocyanine in a binder acts as a surprisingly effective barrier layer against the injection of electrons from metallic bases.
