Abstract:
An electrographic recording element suitable for forming a wallcovering, the element comprising, in order:(a) a backside conductive layer;(b) a base;(c) a filled layer;(d) a frontside conductive layer; and(e) a dielectric layer;wherein:the frontside conductive layer comprises, in polymerized form, 10 to 90 parts by weight of the one or more ethylenically unsaturated ammonium precursors and 10 to 90 parts by weight of the other polymerizable precursors, the parts by weight based on the total weight of the one or more ethylenically unsaturated ammonium precursors and the other polymerizable precursors present in the frontside conductive layer;the one or more ethylenically unsaturated ammonium precursors and the other polymerizable precursors together comprise at least 50 percent by weight of the total solids present in the frontside conductive layer;the surface resistivity of the frontside conductive layer is about 1.times.10.sup.5 .OMEGA./.quadrature. to about 1.times.10.sup.8 .OMEGA./.quadrature.;the surface resistivity of the backside conductive layer is about 1.times.10.sup.5 .OMEGA./.quadrature. to about 1.times.10.sup.8 .OMEGA./.quadrature.;the filled layer comprises a binder or binders and a pigment or pigments, the ratio of total binder to total pigment being about 2.1 to 3.1; andthe element has a wet shrinkage of less than about 2% in the machine direction and less than about 2% in the cross-machine direction.
