Definitions

  • the invention relates to an anti-copying film or a layer consisting of a film or a layer of transparent material with a plurality of non-transparent or reflection layers arranged at approximately equal distances from one another, the planes of which are approximately parallel with respect to one another and in approximately the same predetermined position relative to the surfaces of the film or layer on at least one of the surfaces, so that from a predetermined viewing angle on the surfaces of the anti-copy film it is substantially transparent.
  • an anti-copying film is a transparent plastic film with opaque parts located therein or with an indented or sawtooth-shaped surface in cross-section, wherein a first oblique or vertical surface is either black or reflective with respect to a vertical viewing angle to the level of the film or the document, and the other oblique surface is transparent from a different angle, so that the information or characters are legible.
  • Such notched or sawtooth-shaped surfaces are very difficult to produce, since the surfaces first have to be embossed or hammered in, and then the inclined surfaces have to be provided with a black or reflective material, the accuracy of these operations having to be so great that the transparent surfaces are not affected drawn, ie also partially provided with black and reflective material.
  • black ink is provided in a cross-section which is sawtooth-shaped in the valley between two successive teeth and which at least partially covers part of the substrate. Practical manufacturing designs are not described here either.
  • An anti-copy medium for writing or printing is known from AU-A-610 614, in which the medium contains a photosensitive color system which, when irradiated in a photocopier, makes the writing illegible or makes the copy clearly distinguishable from the original so that either the original becomes worthless or clearly recognizable as copied.
  • an anti-copying film with a single prismatic ribbed surface is known as a protective coating against copying documents and documents.
  • the prism ribbing can be isosceles in cross section or not isosceles. It also describes a Venetian blind film for the same purpose, whereby a transparent film is glued in numerous layers with an opaque colored adhesive and cut into slices at an angle of approximately 60 °, so that a film with continuous, cross-sectionally sloping, opaque layers arises. Such foils are difficult to manufacture.
  • the task is carried out with an anti-copying film or a layer consisting of a film or a layer of transparent material with a plurality of non-transparent or reflection layers arranged at approximately equal distances from one another, the planes of which are roughly the same are arranged parallel to one another and in approximately the same predetermined position with respect to the surfaces of the film or layer on at least one of the surfaces, so that the same is essentially transparent from a predetermined viewing angle on the surfaces of the anti-copying film, in that the Non-transparent or reflective layers are at least partially formed from exposed and, if necessary, developed photosensitive material and that the non-transparent or reflective layers for each anti-copying film or each anti-copying layer are perpendicular or oblique to the surface of the film or layer are arranged.
  • photosensitive material refers to the type of material used, whereby photographic materials must be exposed and developed, whereas, for example, light- or radiation-curing plastics do not require a development process, again in contrast to photo-resist materials, which have to be exposed and developed, the latter by washing out.
  • the non-transparent or reflective layers should at least partially consist of a material that is photochemically convertible, that is to say as a non-transparent one after exposure or irradiation by means of a light or radiation source or reflective material.
  • the non-transparent or reflection layers can be formed as oblique layers through the thickness of the film or the layer.
  • the film or the layer may also be expedient for the film or the layer to be provided on at least one surface with a multiplicity of approximately parallel, approximately equally spaced grooves or grooves in which at least one exposed and, if necessary, developed photosensitive substance is present.
  • the grooves or grooves are arranged perpendicularly or obliquely to the film or layer surface.
  • the grooves or grooves can also have an essentially triangular cross-section, a trapezoidal shape also being understood as part of a triangular shape.
  • the transparent material that is to say the film or the layer itself, already contains the photosensitive material.
  • a very advantageous embodiment of the anti-copying film or the anti-copying layer is obtained if the non-transparent or reflection layers are the first opaque or reflective layers on the top of the film or the layer and the first opaque or reflective layers Layers of second opaque or reflective layers arranged horizontally offset are formed on the underside of the film or layer.
  • Such a groove or groove can advantageously contain the photochemically converted opaque or reflective material.
  • photochemically convertible material is any photosensitive material that changes in its physical properties due to the action of radiation (photons, corpuscles), here changes from a transparent to an opaque state.
  • Figure 1A shows an anti-copy film F or an anti-copy layer, consisting of transparent to transparent plastic material, in which a number of parallel inclined layers SS are provided at equal distances from each other, the layers SS by the total thickness d of the anti-copying film F are continuously formed.
  • the plastic material preferably contains photosensitive substances which are reactive to light of a special wavelength and which make the affected areas opaque or opaque.
  • the effect of light can be limited locally to the predetermined areas of the inclined layers via masks, or rows of light (arrays) or a surface (matrix) can ensure the limited incidence of light.
  • Such "arrays" can be photodiode or diffraction grating arrangements which make it possible to produce a large number of light sources. But it is also possible use one or more locally controlled laser beams.
  • the radiation should be incident obliquely in order to be able to form the oblique layers SS at a predetermined angle ⁇ , between ⁇ about 30 ° to ⁇ about 73 °, in particular at ⁇ about 45 ° to ⁇ about 60 °.
  • Information I of document D is visible through the transparent layers TS at the angle ⁇ or in the direction of the viewing arrows VI. According to arrows VV, however, information I is hidden and invisible.
  • the opacity of the layers SS should therefore be chosen so that the information is at least indistinctly recordable for standard copying machines and is unreadable for humans.
  • FIG. 1B shows an anti-copy film F1 or an anti-copy layer with a sawtooth-shaped surface OS in cross section.
  • the one flanks of the sawtooth shape are e.g. arranged at an angle ⁇ and the others placed approximately vertically.
  • the triangular shape grooves E are in turn filled with photosensitive material containing plastic PH, whereby, as described above, locally limited light, e.g. every second groove E2 becomes opaque (PHE) and every first groove E1 remains partially transparent.
  • the inclined surfaces Q can be designed optically such that total reflection occurs with vertical radiation, or they can be formed with a reflective layer QS. This also results in an oblique viewing direction corresponding to the direction VI and an approximately vertical masking direction VV (FIG. 1).
  • the film or layer material F1 should be transparent to transparent plastic material, which is either designed as a self-supporting film or layer (F1) or is provided with a carrier film or layer G.
  • the grooves of the surface OS can be embossed or during manufacture, e.g. by extrusion or mechanically attached, e.g. by cutting.
  • FIG. 2A shows a further anti-copying film F3 or layer version with longitudinal grooves NU which are approximately rectangular in cross section and which are in turn filled with photosensitive material PH, as described above for FIG. 1B.
  • the plastic of the base material is again transparent to transparent and the grooves NU are made according to the methods described.
  • Material PH is exposed and opaque (PHE) by full-area exposure (arrows LU), as shown by hatching in FIG. 3A.
  • PHE photosensitive material
  • FIG. 2B Another more favorable embodiment of an anti-copying film F3 or layer is shown in FIG. 2B.
  • the diamond-shaped grooves RU here are either produced as grooves NU (FIG. 2A) and then subjected to shear stress in the direction of SR, or already produced in this form by extrusion, cutting, etc.
  • the photosensitive material filling PH is the same, this is introduced e.g. by squeegees.
  • the finished anti-copying film F3 or layer with opaque inclined layers SS in the angular range ⁇ is obtained with FIG. 3A.
  • the grooves NU and RU are formed approximately up to half the thickness d of the film F2 and F3. They can also be deeper.
  • the depth T of the grooves NU and RU can only be formed if a carrier film or layer G, not shown here, is used, to which the layer F2 or F3 is attached or applied.
  • FIG. 4A shows a rectangular groove film F4 or layer compared to F2 on both sides and provided with rectangular grooves NU.
  • the grooves NU1 on the top and NU2 on the bottom are arranged offset from one another.
  • the opaque groove content is produced as described above using a photochemical material PH and its full-area exposure (PHE).
  • Partial information is visible in directions VI and VII, the completeness of the visible information increasing with a decrease in the depth T of the grooves NU1 and NU2 regardless of the width bb of the individual grooves NU1 and NU2.
  • FIG. 4B shows a film or layer design F5 corresponding to FIG. 4A, which, in contrast to F3, is formed on both sides with inclined layers SS1 and SS2, which can be produced as described above.
  • the inclined layers SS1 and SS2 are horizontally offset from one another.
  • the information I is hidden in the vertical viewing direction VV and at least partially visible in the oblique direction VI.
  • Anti-copy film or layer consisting of a film or a layer of transparent material with a plurality of spaced apart, at least partially non-transparent areas, the planes of which are arranged in approximately the same predetermined position with respect to the surfaces of the film or layer are such that the same is substantially transparent from a predetermined viewing angle on the surfaces of the anti-copying film.
  • the areas consist at least partially of a photosensitive material which is converted into non-transparent or reflective material by the action of radiation, wherein grooves or grooves in which the photosensitive material is located can also be provided in the transparent plastic material.
