Abstract
The method of coating a pervious fibre sheet with a photoconductor in which the photoconductor, a resin and a solvent for the resin are each selected and combined to have different penetrating power when applied to the pervious sheet whereby the photoconductor has a minimum penetration, the resin has a greater penetration and the solvent has the greater penetration, the components being selected to have an increasing dielectric constant inwards from the surface of the sheet, the resin being hydrophobic and capable of wetting both the photoconductor and the fibre.
