ABSTRACT:
A process of manufacturing a cathode-ray tube (21) having a faceplate panel (27) with an exterior surface (39) having thereon an anti-glare, anti-static, dark coating (37) is described. The process is characterized by the steps of (a) forming a substantially homogeneous initial carbon dispersion containing substantially equal parts, by weight, of carbon particles and an organic vehicle; and (b) combining a sufficient quantity of the homogeneous initial carbon dispersion with an aqueous solution of lithium polysilicate to form a final dispersion suitable for application to the faceplate of the CRT.
