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.
Claims12
A process for producing a cathode ray tube comprising the steps of:
- mixing an alcohol solution of an acid and a partially hydrolyzed alkylsilicate monomer with an amount of water being at least four times greater than the number of moles of said alkylsilicate;
- applying the mixed solution to the outer surface of a panel by spin coating to form a coating thereon;
- and
- heating the resulting coating to a temperature in the range of 150.degree. to 200.degree. C. for 5 to 30 minutes to form an antistatic and non-glare coating.
