    Abstract: A coating composition for a cathode ray tube, comprising the ingredients of: silica powder which has been fused during the process of flame spraying, said silica powder having an average particle size of about 0.02 to about 15 microns, electrically conductive graphite powder, with the pigment ratio of silica to graphite being within the range of 0.1 to 15, an organic thickening agent, water glass, and the balance water, said coating composition having a viscosity within the range of about 270 to about 850 cps; and wherein the coating provides markedly improved intercoat adhesion between overlapping coatings on the interior funnel of the cathode ray tube.
