ANTISTATIC COMPOSITIONS AND ELEMENTS Abstract of the Disclosure Antistatic compositions comprising a highly cross- linked vinylbenzyl quaternary ammonium copolymer and a hydro- phobic binder are described. Elements, particularly photo- graphic elements, having a layer of the antistatic compositions are also described. The compositions are characterized by a binder to antistatic copolymer ratio of about 10:1 to 1:1. The compositions are highly conductive in thin layers and retain substantial conductivity at low relative humidity. Layers of the antistatic compositions are particularly useful for photographic elements because they can be contacted over a wide range of conditions with a hydrophilic layer without resulting in ferrotyping. -1-
