Provided is a coating for forming a conductive release layer capable of forming a conductive release layer having high adhesion to a film base material, suppressing deterioration in conductivity over time in the air, and having a sufficient releasing property. The coating for forming a conductive release layer of the present invention contains a conductive composite including a π-conjugated conductive polymer and a polyanion, an epoxy compound having an epoxy group, a curable silicone, a polyester resin, and an organic solvent.

Charged polymeric webs, such as electret webs, include a thermoplastic resin and a charge-enhancing additive. The charge-enhancing additive is a dual-function charge-enhancing additive that enhances the charge of the electret and also has anti-microbial properties. The additives are substituted-benzimidazole or substituted-benzothiazole compounds. The electret webs may be a non-woven fibrous web or a film. The electret webs are suitable for use as filter media.
