  • the invention is concerned with a method of producing a composite printing foil having an aluminum printing face and including an aluminum foil formed with spaced projections or protuberances extending outwardly at the printing face and preferably uniformly distributed thereon, and a supporting layer adhering to the other face of the thus embossed aluminum foil.
  • Printing foils of aluminum embossed so as to form uniformly distributed projections at one face thereof were proposed, as well as printing foils of said type which were coated with a very thin lacquer layer at their other face.
  • the present invention proposes to produce a composite printing foil by applying to one face of a metal foil, preferably an aluminum foil, formed with spaced projections extending outwardly at the other face of the foil.
  • a supporting layer consisting of a synthetic resin which may be applied as a synthetic resin foil or which layer may be formed for instance from an aqueous suspension, or of a coherent fibrous layer such as a paper sheet.
  • the present invention also encompasses the thus formed composite printing foil.
  • FIG. 1 is a cross-sectional view of an embodiment according to the present invention in which a supporting paper sheet is adhesively attached to the metal foil;
  • FIG. 2 is a cross-sectional view of a second embodiment in which a foil of synthetic material is adhesively attached to the metal foil;
  • FIG. 3 is a cross-sectional view of a third embodiment in which the metal foil is coated on one face with a layer of synthetic material.
  • the aluminum foil after embossing the same so as to form, preferably uniformly dis tributed, spaced projections at the printing face thereof, is
  • Such supporting layer may directly adhere to the aluminum foil or may be adhered thereto by interposition of an adhesive material which may be a cold-acting adhesive, or an adhesive which is to be activated or hardened by exposure to elevated temperatures.
  • thermoplastic resin to the face of thc embossed aluminum foil which is opposite the printing face thereof in the form of an aqueous dispersion and to form the supporting layer by evaporation of at least the major portion of the water of the dispersion, a method which per se is known to those skilled in the art.
  • the composite printing foil of the present invention has on the face thereof which is to be exposed to pressure by an indicia forming device.
  • an indicia forming device for instance a typewriter key, a layer or foil consisting of synthetic resin or paper and firmly adhering to the respective face of the aluminum foil.
  • the thickness of the aluminum foil prior to the embossing thereof will be about 50 microns and the layer or sheet which is adhered thereto will have a thickness of between about 25 and 75 microns.
  • the composite printing foil consists of an aluminum foil having a thickness of about 50 microns and being embossed as described above so as to have uniformly distributed spaced projections at the printing face thereof, and having adhered thereto at the face of the aluminum foil which-is opposite the printing face thereof, by means of a cold or hot acting binder material a paper sheet having a thickness of between about 25 and 75 microns.
  • the embossed aluminum printing foil may be combined, in accordance with the present invention, with a foil of synthetic material adhering to the face of the aluminum foil which is opposite the printing face thereof.
  • a foil of synthetic material may consist for instance of cellulose acetate, regenerated cellulose, polyethylene, terephthalic acid ester or polyvinyl chloride.
  • the composite printing foil may also be produced by forming a layer of synthetic material on the aluminum foil, preferably a layer having a thickness of between about 25 and 75 microns and consisting of polyethylene, polyvinyl chloride or polyvinyl acetate.
  • FIG. I a schematic cross-sectional view of a composite embossed printing foil is shown, having an embossed aluminum printing face and a supporting paper sheet which is adhesively adhered to the face of the aluminum foil which is opposite the printing face thereof.
  • Embossed metal foil 1 for instance consisting of aluminum or aluminum alloys known to those skilled in the art, is of the type which may be used for producing copies in a large number and over a prolonged period of time.
  • Foil 1 is formed with evenly distributed small protruding points 2 which extend outwardly at the printing face of the foil.
  • reproducible indicia on the foil, for instance by the impact of a typewriter key in the direction from the nonprinting towards the printing surface of the foil, raised indicia 3 are formed which extend outwardly beyond the level of points 2.
  • a paper layer 4 is applied to the nonprinting surface of the metal foil, after embossing and prior to imprinting of the same, by means of an interposed conventional water insoluble adhesive layer 5.
  • metal foil .1 is adhered by means of a hot sealing adhesive 7 to a commercially available foil 6 of synthetic material, for instanceof polyethylene, polyvinyl chloride, cellulose acetate or polyterephthalic acid ester.
  • the hot sealing of foil 6 to aluminum foil 1 is carried out afier embossing but prior to imprinting of aluminum foil 1.

  • a layer 8 formed of a dispersion of synthetic material, for instance of an aqueous dispersion, in, per se, conventional manner.
  • Application of the dispersion or the like layer is carried out after embossing and prior to imprinting of the aluminum foil, and it will be noted that in accordance with the last described embodiment the interposition of an adhesive layer between the aluminum foil and the reinforcing layer will not be required.
  • a printing form comprising an aluminum foil formed at its printing face with spaced outwardly extending projections and being covered at its other face and a firmly adhering sheet, foil or layer of terephthalic acid.
  • the latter being highly resistant against chemical attack by. for instance, an interposed adhesive if such adhesive is employed, and by cleaning agents conventionally used for cleaning the printing form.
  • the layer of terephthalic acid ester does not tend to roll up upon itself, or-if at all-only to a very slight degree.
  • a method of producing a composite lithographic printing plate comprising the steps of embossing a metal foil so as to form on one face thereof spaced depressions and on the other face thereof corresponding spaced projections extending outwardly from said other face of said metal foil; applying to said metal foil a supporting layer of a material selected from the group consisting of synthetic Y resins and coherent fibrous layers so as to fill also said depres- 4 sions; and subsequently forming in said embossed metal foil and supporting layer raised indicia-forming portions protruding from said other face of said embossed metal foil and extending beyondsaid spaced projections thereon, said raised indicia-forming rtions beingformed by applying pressure onto said suppo ing layer on said one face of said metal foil in the region of said raised indicia-forming portions.
