ABSTRACT:
A method of producing a graphite-based conductive coating composition to be applied to the interior wall of a color picture (cathode-ray) tube, which method comprises the steps of preparing a mixed solution of electroconductive materials by mixing graphite particles, a metal oxide and a surface treating agent with water, producing an electroconductive powder by instantaneously drying said mixed solution, and mixing said electroconductive powder with a silicate and a dispersant in water and stirring the mixture. Said metal oxide, which is a component of said mixed solution, is preferably titanium oxide and the like and said surface treating agent is preferably silicon oxide. It is also desirable that said mixed solution of electroconductive materials be dried instantaneously by spray drying.
