ABSTRACT:
The inventive silicon-based coating composition provides an antistatic surface-releasing coating layer on a plastic film without the need of any antistatic undercoating. The coating composition comprises, in addition to the conventional ingredients in similar coating compositions including a vinyl-containing organopolysiloxane, an organohydrogenpolysiloxane and a platinum catalyst, a salt, e.g. nitrate and perchlorate, of a metal of the Ist, IInd or VIIIth Group of the Periodic Table and a specific organopolysiloxane having at least one per molecule of alkanolic pendant groups of the formula HO(CH.sub.2 CH.sub.2 O).sub.n CH.sub.2 CH.sub.2 CH.sub.2 --, in which n is 1 to 9.
