A photographic imaging element is disclosed which comprises a support having on one side thereof at least one silver halide emulsion layer and having, in order, on the opposite side thereof an electrically-conductive layer coated from a coating composition comprising a polythiophene/polyanion composition containing a polythiophene with conjugated polymer backbone component and a polymeric polyanion component, and a protective topcoat comprised of a polyurethane binder which has a tensile elongation to break of at least 50% and a Young's modulus measured at 2% elongation of at least 50000 lb/in2; wherein the electrical resistivity of the electrically-conductive layer before photographic processing is less than 2×109 Ω/□, after photographic processing is between 1×109 Ω/□ and 1×1011 Ω/□, and increases by at least one order of magnitude as a result of photographic processing. Photographic imaging elements of the invention effectively minimize both raw (pre-photographic processing) static marking and processed (after photographic processing) photographic element sticking caused by the accumulation of electrostatic charges, and additionally have excellent resistance to scratch and abrasion.
A multicolor motion picture photographic print film element comprising a support having on one side thereof, in order, a yellow dye image-forming unit comprising at least one blue-sensitive silver halide emulsion layer having associated therewith at least one yellow dye-forming coupler, a cyan dye image-forming unit comprised of at least one red-sensitive silver halide emulsion layer having associated therewith at least one cyan dye-forming coupler, and a magenta dye image-forming unit comprising at least one green-sensitive silver halide emulsion layer having associated therewith at least one magenta dye-forming coupler, and having, in order, on the opposite side thereof:
