Abstract
Abstract An antistatic coating composition, a manufacturing process thereof, and an antistatic and non-glare picture displaying screen are disclosed. The manufacturing process for the antistatic coating composition comprises steps of forming a silicate solution by partially hydrolysing a silicate substance; forming a conductive solution containing a conductive material which is formed by doping a soluble inorganic compound and a different inorganic compound into molecular water-containing oxides or hydroxides of a soluble inorganic compound which is soluble in an organic compound and water; and mixing the silicate solution and the conductive solution, and subjecting the mixture to a hydrolysis and to a polycondensation. According to the present invention, the antistatic and non-glare effects are greatly promoted.
