ABSTRACT:
A cathode ray tube having an antistatic and non-glare coating with a controlled and uniform degree of unevenness, can be produced by the process which comprises the steps of mixing an alcohol solution of an acid and a partially hydrolyzed alkylsilicate monomer with an amount of water being of at least four times greater than the number of moles of the alkylsilicate; applying the mixed solution to the outer surface of the panel by spin coating; followed by heating the resulting coating to a temperature in the range of 150.degree. to 200.degree. C. to form an antistatic and non-glare coating.
