Abstract
In accordance with the present invention a photographic element contains a first electrically-conductive layer and a second electrically-conductive layer. The first conductive layer has an electrical resistivity of less than 1.times.10.sup.9 .OMEGA./.quadrature. before film processing and an electrical resistivity of greater than 1.times.10.sup.11 .OMEGA./.quadrature. after film processing. The second conductive layer has an electrical resistivity of between 1.times.10.sup.9 .OMEGA./.quadrature. and 1.times.10.sup.11 .OMEGA./.quadrature. both before and after film processing. Both of the electrically-conductive layers are transparent. In an alternative embodiment, the photographic element contains a transparent electrically-conductive layer containing a first electrically-conductive agent and a second electrically-conductive agent. The electrically-conductive layer has an electrical resistivity of less than 1.times.10.sup.9 .OMEGA./.quadrature. before film processing and has an electrical resistivity of between 1.times.10.sup.9 .OMEGA./.quadrature. and 1.times.10.sup.11 .OMEGA./.quadrature. after film processing. The first conductive agent is one in which the conductive properties of the material do not survive film processing. The second conductive agent is one in which the conductive properties of the material are substantially unaffected as a result of film processing.
