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 of a type created by coating the interior surface of the faceplate 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 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 one of charged phosphor particles and light-absorptive material particles, depending upon the polarity of the charged particles, the solution consisting of:0.01 to 10% by weight of bis dimethyl phenyl diphenyl butatriene;1 to 30% by weight of polystyrene;30 to 100% by weight of 2,5-bis(4-diethyl aminophenyl)-1,3,4-oxadiazole based on 100% by weight of polystyrene; andthe remainder being a solvent.
