Abstract:
A solution for forming a photoconductive layer for electrophotographically manufacturing a luminescent screen on an interior surface of a faceplate panel for a CRT created by coating said surface of the panel with a volatilizable conductive layer and an overlying volatilizable photoconductive layer, establishing a substantially uniform electrostatic charge over the whole area of the inner surface of the photoconductive layer, exposing selected areas of the photoconductive layer to discharge the charge from the selected areas, developing one of the charged, unexposed areas and the discharged, exposed areas with charged phosphor particles or light-absorptive material particles, depending upon the polarity of the charged particles, the solution comprising as required components:2 to 5% by weight of tetracyanoethylene as an ultraviolet-sensitive material;0.1 to 1% by weight of dephenylpicrylhydrazine (DPPH); and less than 0.1% by weight of tetracyanoquinodimethane (TCNQ).
