    摘要： 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/in ; wherein the electrical resistivity of the electrically-conductive layer before photographic processing is less than 2 x 10 OMEGA / &squ& , after photographic processing is between 1 x 10 OMEGA / &squ& and 1 x 10 OMEGA / &squ& , 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.

    摘要： Nonpolymeric fluorochemicals defined as by the following Structure I are useful in thermally developable materials. The fluorochemicals are defined as follows: R f -R-N(R 1 )(R 2 )(R 3 ) + X - (I) wherein R f is a straight or branched chain perfluoroalkyl group having 4 to 18 carbon atoms, R is a divalent linking group comprising at least 4 carbon atoms and a sulfide group in the chain, R 1 , R 2 , R 3 are independently hydrogen or alkyl groups or any two of R 1 , R 2 , and R 3 taken together can represent the carbon and nitrogen atoms necessary to provide a 5- to 7-membered heterocyclic ring with the cationic nitrogen atom, and X - is a monovalent anion.
