ABSTRACT:
A process for forming a conductive substrate comprises coating onto a polyethylene terephthalate substrate an aqueous coating solution containing a conductive crosslinkable polymer with charge carrying groups such as sulfonic acid, sulfuric acid ester or quaternary ammonium salt groups attached to a polymerized ethylenic monomer backbone, a volatile amine in an amount to maintain a pH of above 7.0 and a crosslinking agent such as a polyfunctional aziridine, removing water and the volatile amine which decreases the pH to below 7.0 wherein a reaction between the crosslinkable groups of the polymer and the crosslinking agent is initiated to form a crosslinked conductive polymer film.
