Paper having a surface coating of exfoliated three-layer clay exhibiting a surface conductivity of 108-1010 ohms/sq. at relative humidities from 12-15 percent may be used for making a copy sheet for electrophotography by providing an overcoating of zinc oxide. An aqueous dispersion of exfoliated three-layer clay together with water soluble electroconductive inorganic compound is described.
