Abstract
A conductive substrate for use in a photographic element comprises a polyethylene terephthalate support coated with 0.01-10 g/m.sup.2 of a conductive layer having a low surface energy during coating and a high surface energy after coating which is the reaction product of (i) a conductive crosslinkable polymer with charge carrying groups such as sulfonic acid groups, (ii) a volatile amine and (iii) a crosslinking agent such as a polyfunctional aziridine.
