    摘要： Disclosed is a multilayer compensator polymeric film for a LC cell including two or more first type layers having an out-of-plane birefringence not more negative than −0.005 and one or more second type layers having an out-of-plane birefringence more negative than −0.005, wherein the second type layers are amorphous and including selected polymeric materials having sufficient thickness so that the overall in-plane retardation (Re) of the compensator is from 0 to 300 nm and the out-of-plane retardation (Rth) of at least one of the one or more second type layers is more negative than −20 nm wherein: (a) a first type layer is present that is contiguous to a second layer and is between all of the second type layers and all of the other first type layers; (b) at least one of the second type layers or one of the other first type layers is a layer coated from an organic solvent; and (c) the contiguous first type layer contains a polymer that is water soluble or water dispersible in an amount sufficient to impede the diffusion of the organic solvent between the other first type layers and the second type layers.

    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/in2; wherein the electrical resistivity of the electrically-conductive layer before photographic processing is less than 2×109 &OHgr;/□, after photographic processing is between 1×109 &OHgr;/□ and 1×1011 &OHgr;/□, 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： The present invention is an imaging element having, a support, an image-forming layer superposed on the support and an outermost scratch resistant antistatic layer superposed on the support. The outermost scratch resistant antistatic layer has a thickness between 0.6 and 10 microns. The scratch resistant layer is composed of a polymer having a modulus greater than 100 MPa measured at 20° C. and a tensile elongation to break greater than 50%, a filler particle having a modulus greater than 10 GPa, and an electrically conducting polymer. The volume ratio of the polymer to the filler particle is between 70:30 and 40:60 and the electrically conducting polymer is present at a weight concentration based on a total dried weight of the scratch resistant layer of between 1 and 10 weight percent.
