ABSTRACT:
In accordance with this invention, a photographic film especially suited for motion imaging film applications such as motion picture film or television film has on one side of a support material, in order, a process surviving, electrically conductive subbing layer, a photographic emulsion, and a protective overcoat; and on the opposite side a carbon black-containing backing layer, and optionally, a lubricant that overlies the backing layer. The carbon black-containing layer provides antihalation and antistatic protection for the unprocessed film. The conductive subbing layer retains its antistatic properties after processing so that the motion imaging film is protected from the generation of static charge after the carbon black-containing layer is removed during processing. The conductive subbing layer has a resistivity of less than 5.times.10.sup.9 .OMEGA./.quadrature. after film processing.
