| 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 binder, at least one solvent, and at least one compound of formula R 1 —O—[(CH 2 —CHR′)—O] n —R 2 , wherein R 1 and R 2 independently represent an alkyl group, R′ is H or methyl and n is an integer ranging from 2 to 225. Said coating exhibits superior abrasion resistance properties when the binder is an epoxysilane, preferably an epoxyalkoxysilane. 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 antistatic properties, high optical transparency with about 91-92% of transmittance, low haze and improved abrasion resistance. |
