| abstract |
The present invention relates to a curable composition, providing, upon curing, a transparent, antistatic coating, comprising at least one conductive polymer, at least one epoxysilane binder, at least one solvent, and at least one compound of formula R 1 - [R 2 ] n - OSO 3 H or R 1 -[R 2 ] n -SO 3 H or a salt thereof, wherein n = 0 or 1, R 1 is H or a substituted or unsubstituted alkyl group, and R 2 is a substituted or unsubstituted arylene group, with the proviso that the compound of formula II is not a fluorine containing surfactant. The invention further relates to optical articles comprising a substrate at least partially coated with a transparent antistatic coating formed by depositing onto the substrate and curing the above curable composition. The obtained optical articles exhibit enhanced antistatic properties, high optical transparency with about 91% transmittance, and low haze. |
