Beschreibung
Zusammenfassung:	The present invention relates to a curable composition providing upon curing a transparent antistatic coating comprising a silica organosol, a salt comprising an alkali cation and a Bronsted acid. The invention further relates to optical articles comprising a substrate at least partially coated with a transparent antistatic coating formed by depositing onto substrate and curing the above curable composition. The obtained optical articles exhibit enhanced antistatic properties, high optical transparency, low haze and good mechanical properties, in particular a good abrasion resistance.
