Abstract: A method and apparatus are taught for treating paper webs for obtaining the proper surface characteristics to promote adhesion of nonphotosensitive coating materials and/or layers typically coated thereon. The web is passed through a high-voltage sheath region or dark space of the plasma generated by a powered electrode residing in a discharge zone. The frequency of the driving voltage must be above a lower bound dictated by the properties of the paper support and the plasma, and it must be below an upper bound beyond which the sheath voltages drop significantly and it is observed that the benefits of this approach diminish. The dark space is generated by a treatment electrode in a treatment zone. There is a counter electrode having a surface area in said treatment zone which is at least as great as the surface area of the treatment electrode.

Abstract: An imaging support element comprising a polymeric film support and a thermally stable single subbing layer is made by forming a coating over the polymeric film support, the coating having a surface including amine reactive groups in a density of at least 1010 per cm2 and then heat treating the polymeric film support with the coating thereon at a temperature in the range of from about 50° C. below the glass transition temperature (Tg) of the polymeric support up to the glass transition temperature (Tg) of the polymeric support. The polymeric film support is nitrogen plasma treated. The layer is preferably formed by coating a monomer solution on the nitrogen plasma treated polymer support wherein the coated monomer has at least two vinyl sulfone groups which provide the amine reactive groups. Alternatively, the layer may be formed by applying to the polymeric support web a coating including at least one non-amine reactive comonomer and at least one comonomer having amine reactive side groups.

Abstract: The present invention comprises a polyester film support in which the surface has been subjected to an energetic treatment with nitrogen plasma to produce amine groups on the polyester surface. The treated surface is then coated with a dilute solution of amine reactive hardener and gelatin. After drying the hardener/gelatin coated support a photographic emulsion is coated on the surface. The resulting film element has excellent adhesion of the photographic emulsion after photoprocessing, and it is safer to coat and handle than previously known methods involving grafting of hardener directly to the support.

Abstract: Imaging elements, such as photographic, electrostatographic and thermal imaging elements, are comprised of a support, an image-forming layer and an electrically-conductive layer produced bycoating a layer comprised of a metallo-organic compound and a film-forming binder and subjecting such layer to glow discharge treatment to render it electrically conductive. Use of a metallo-organic compound in combination with a glow discharge treatment provides a controlled degree of electrical conductivity and beneficial chemical, physical and optical properties which adapt the electrically-conductive layer for such purposes as providing protection against static or serving as an electrode which takes part in an image-forming process.
