    摘要： Disclosed is a multilayer compensator polymeric film for a LC cell comprising two or more first layers having an out-of-plane birefringence not more negative than −0.005 and one or more second layers having an out-of-plane birefringence more negative than −0.005, wherein the second layers are amorphous and comprise 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 layers is more negative than −20 nm wherein: (a) a first layer is present that is contiguous to a second layer and is between all of the second layers and all of the other first layers; (b) at least one of the second layers or one of the other first layers is a layer coated from an organic solvent; and (c) the contiguous first 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 layers and the second layers.

    摘要： The present invention is an imaging element which includes a support, an image forming layer superposed on the support; and an antistatic layer superposed on the support. The antistatic layer includes electrically conductive particles at a 10-60 volume percent and microgel particles. The microgel particles are composed of 25 to about 80 weight percent of an oleophilic monomer, 5 to about 45 weight percent of a hydrophilic monomer, and 0 to 20 weight percent of a crosslinking monomer having at least two addition polymerizable groups. In an alternative embodiment the antistatic layer also includes a binder.
