ABSTRACT:
A recording material is described, which comprises a support of paper or of synthetic polymer and an electroconductive layer on at least one side of the support. The surface resistance of this electroconductive layer is not more than 10.sup.11 ohms per sq. at a relative humidity of 15%. The layer consists or includes a major proportion of a water-soluble polymer resulting from the amino alkylation of polyethyleneimine with an epoxy compound bearing a quaternary ammonium end group.
The electroconductive layers may be used as antistatic layers in a photographic silver halide recording material. When covered with a photoconductive coating the electroconductive layer may be used in electrophotographic recording materials. When an insulating layer is applied on the electroconductive layer an electrographic recording material is formed.
