SCRATCH RESISTANT RECORDING MATERIALS FOR ELECTROEROSION PRINTING NOT REQUIRING A LUBICANT OVERCOAT ABSTRACT OF THE DISCLOSURE Electroerosion recording materials of superior scratch resistance are provided without the need for a lubricant overcoat by incorporating a hard, luricating hydrophobic polymer layer between the support and the removable, thin conductive layer to reduce plastic deformation of the support under stylus writing pressure. The intermediate polymer layer provides a highly adhering surface for the overlying aluminum film and contains graphite fluoride and/or fluorocarbon resins such as TeflonR and hard particles such as silica. The materials may be used in various printing processes including making directly readable images, direct negatives and wear resistant offset printing masters.
