Abstract (en)
[origin: US4390609A] An electrophotographic recording material comprising an electrically conductive support, an optional insulating intermediate layer, at least one photoconductive layer comprising a charge carrier generating compound and a charge transporting compound, and a protective transparent cover layer made from a surface abrasion resistant binder composed of a polyurethane resin, polycarbonate resin, phenoxy resin, polyacrylate or polymethacrylate resin, polyurethane formed from a two-component system comprising a polyisocyanate and a hydroxyl group containing polyester or polyether, a polyisocyanate and a hydroxyl group containing acrylic or epoxy resin, polyurethane formed from a one-component system comprising a polyisocyanate prepolymer, or a polyisocyanate having temporarily masked isocyanate groups.
