Electrographic imaging element

A method for forming electrographic imaging elements comprising a uniform dielectric layer is disclosed. The method comprises coating a conductive coating composition containing polymerizable precursors onto a base, curing the composition to form a conductive layer, and coating a dielectric layer on top of the conductive layer. The elements can be used to produce images have higher image density, reduced background, reduced grain, reduced mottle, reduced overtoning, and greater small-scale uniformity than comparable images formed on electrographic imaging elements produced by other methods. The elements are particularly useful for forming large size colored images, such as are required for posters, displays, other indoor advertising.
