<p>An antistatic coating was provided on a substrate 10 by dispersing latex particles 12 from a polypyrrole compound in an aqueous solution of a hydrolysed alkoxysilane compound, after which the dispersion was applied to the substrate. The hydrolysed alkoxysilane compound was converted to silicon dioxide by means of a treatment at an increased temperature, thereby forming a matrix 14 in which the latex particles 12 are dispersed and by means of which the latex particles are adhesively secured to the substrate 10. The antistatic coating can particularly suitably be used on the display screen of a cathode ray tube, and, if desired, said coating can simultaneously be used to reduce the light transmission of the display screen. <IMAGE></p> |
