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.
