Detailed description of the invention

As a example by banknote, explain now the present invention.Fig. 1 schematically shows banknote 10 for this, wherein at banknote paper 12 On be applied with the Security element of the form with metalized holographic bar 14.Holographic bar 14 shows that hologram, described hologram exist Embodiment is made up of the sequence of the portrait 16 of banknote 10 and the repetition of face amount " 50 " (drawing reference numeral 18).

Additionally, in the region of holographic bar 14, banknote 10 provides according to the present invention with signature identification 30, described signature identification 30 have in transmission light relative to the eye impression changed in reflection light.This eye impression changed is further below The different view of Fig. 4 illustrates, and certainly can not describe according to verity in the schematic full graphic of Fig. 1.

Identifying 30 for Expressive Features more accurately, Fig. 2 shows the banknote 10 detail portion in the region of signature identification 30 Point, and Fig. 3 shows the cross section of the line III-III along Fig. 2.

As shown in Figure 3 the cross-section, it is applied to the most suprabasil holographic bar 14 of bank-note paper 12 comprise Impressing enamelled coating 20, is embossed with portrait 16 and the desired holographic structure 22 of numeral 18 in described impressing enamelled coating 20, and Including the holographic metallization 24 such as formed by aluminum being applied on described impressing enamelled coating 20.Therefore, holographic Figure 16,18 become Reflection hologram, it gives eye impression (Fig. 4 a) when observing on front side of banknote in reflecting light.

Cross section shown in iting should be understood that in figure 3 is only illustrative diagram, and such as holography bar 14 or bank-note paper And therefore 12 can have other layer, and described other layer is generally unprofitable to the optical effect according to inventive feature mark, No longer illustrate.Such as, banknote substrate and/or Security element can have one or more adhesive phase and/or prime coat.As long as carrying These layers are supplied, by applying with laser emission if desired for just removing these layers or revise their image.

Additionally, the layer shown in figure 3 also can additionally be arranged.Such as, metallization 24 is also disposed at bank-note paper 12 And between enamelled coating 20.This variant has the additional advantage relative to embodiment shown in figure 3, i.e. holographic structure and metal Change portion is secured against amendment and other forgery trial by being arranged between substrate and enamelled coating.Also this can be implemented shape Formula is applied in target substrate with printing transferring method.

With reference to the top view of Fig. 2, signature identification 30 is made up of two parts, and includes fisrt feature identification division and the second spy Levy identification division, by applying with laser emission to bank-note paper 12 and holographic bar 14, produce described in the identical course of processing Two signature identification parts, and therefore they despite different signature identifications but can the most mutually registrate.

As fisrt feature identification division, the signature identification 30 laser hole 32 containing rasterizing, described laser hole 32 passes through Line grating including a plurality of parallel line of cut 34 is formed, and these lines of cut extend through bank-note paper 12 and holographic bar 14.Grid The laser hole 32 formatted is generally constructed as the form with pattern, mark or code, and has in an embodiment at tetragon The shape of the Folium Alangii 36 in frame 38.

As second feature identification division, signature identification 30 comprises modifier area 40, banknote in described modifier area 40 Paper 12 is not cut, but the most only eliminates the metallization 24 of holographic bar 14 in multiple parallel metallization removal lines 42, And therefore have modified the image of holographic bar 14.

As the most visible, metallization removal line 42 well with the line of cut 34 being in outside modifier area 40 Registration.Metallization removal line 42 ensures in the following way with the well registration of line of cut 34: two kinds of lines 34,42 are by with identical Processing laser beam in the identical course of processing, apply laser and produce.Different processing results, i.e. holographic bar 14 and banknote The cutting of paper 12 and the metallization removal of only holographic metallization 24, by laser parameter, especially laser power and/or cutting Speed changes realization in the course of processing accordingly.

As shown in FIG. 3, the region of line of cut 34 covers with transparent thin film 50 respectively in both sides.This covering can only be wrapped Include cutting line area, or also can the most such as extend on whole banknote 10.With " thin film/with false proof Substrate/the thin film of element " Rotating fields complex banknote in the case of realize goodly this cover.Here, not only cut Line region and whole holographic bar 14 can be completely disposed between complex thin film 50 and therefore be protected particularly well.

Illustrate in the diagram and print with the different vision of banknote 10 during dorsal part on front side of observing in reflecting light or transmission light As, wherein Fig. 4 a shows the eye impression when front side viewed in reflected light, and Fig. 4 b shows when front side viewed in transmitted light Eye impression, Fig. 4 c shows the eye impression when dorsal part viewed in reflected light, and Fig. 4 d shows in dorsal part viewed in transmitted light Time eye impression.

With reference first to Fig. 4 a, when observing on front side of banknote in reflecting light, holographic reflection holography Figure 16 of bar 14,18 give Eye impression.The profile 38 in the outside of the laser hole of rasterizing is faint visible, but the shape of Folium Alangii 36 is invisible, because ideally Mutually metallization removal line 42 and the line of cut 34 of registration only has the least contrast difference for eyes.From reconstructed hologram 16, on the direction of observation of 18, hologram after all crosses laser hole 32 and the modifier area 40 of exposure cage.Additionally, due to remove gold Genusization line 42 and the least contrast difference of line of cut 34, internal theme " Folium Alangii " 36 be only hardly visible holographic Figure 16,18 Viewing angle under the most invisible.

If observed transmission light on front side of it by banknote now, then the design 36 of the laser hole 32 of rasterizing is shockingly Entrance prospect, as illustrated in fig. 4b.The wire grid of line of cut 34 in transmission light at the metallization 24 of holographic bar 14 Dark background highlights highlightedly.Profile and the metallization removal line 42 of Folium Alangii 36 are the most visible in transmission light, certainly due to The bank-note paper 12 that still suffers from modifier area 40 and with lower brightness.The most in a word, changing to transmission light from reflection light Time, create the conversion of the reversion of the image of signature identification 30.

With reference to Fig. 4 c, when observing the dorsal part of banknote 10 in reflecting light, paper money is passed through in the design 36 of the laser hole 32 of rasterizing Line of cut 34 in ticket paper is the most visible.It is applied to the holographic bar 14 on front side and metallization removal line 42 on dorsal part in reflection In light invisible so that the inside of Folium Alangii 36 does not manifest structure.If the laser hole 32 of the rasterizing of dorsal part is invisible, then banknote Dorsal part also is provided with at this being substantially non-transparent layer, especially receives the layer of color.

When the viewed in transmitted light of dorsal part, the eye impression of banknote 10 corresponds essentially to front side impression.As in figure 4d Illustrated, in transmission light the wire grid of line of cut 34 and metallization removal line 42 in the dark background of metallization 24 well Visible.

For transferring to the attention of observer reflect light/transmission light change, the laser hole of rasterizing can be from holographic bar 14 Laterally projecting.Then, user recognizes the part of laser hole of rasterizing on front side of banknote reflection light, and therefore by Excite viewed in transmitted light.Then occur in that wonderful other design at this, i.e. hidden by holographic bar 14 in reflection light Or the laser hole of rasterizing given by part.This wonderful supplementary result is in fig. 5 and fig. according to two embodiments Diagram.

The embodiment embodiment based on Fig. 4 of Fig. 5, the laser hole 32 of the rasterizing of certain Fig. 5 not only comprises by holographic bar The design of 14 Folium Alangives 36 being in square frame 38 covered, and additionally comprise design 60, in described design 60 Face amount " 50 " (drawing reference numeral 62) is arranged in oval frame 64.

This design part 60 of the laser hole 32 of rasterizing is lateral side by side, but directly adjacent holographic bar 14 is arranged, and because of Even if also showing during the viewed in reflected light that this is on front side of banknote, as illustrated in fig 5 a.If the present backlight of user holds paper money Ticket is so that design 60 can preferably be identified, then supplementing as the eye impression for design 60, occurs in that astoundingly Folium Alangii 36 in square frame 38, as shown in figure 5b.

When observing banknote dorsal part, except the design part 60 additionally existed, this image is corresponding to the image of Fig. 4.? When observing in reflection light, the face amount 62 of the laser hole 32 of Folium Alangii 36 and rasterizing is clearly visible by the line of cut 34 in bank-note paper, As shown in fig. 5 c.The inside of Folium Alangii 36 shows as structureless at this, because the holographic bar 14 being applied on front side and going Metallized thread 42 is invisible in reflection light on dorsal part.Therefore, transmission light additionally occurs in that metallization removal line 42, institute State metallization removal line 42 to highlight in the dark background of metallization 24 together with line of cut 34, as illustrated in figure 5d highlightedly Property ground diagram.

In the embodiment in fig 6, compared with the structure of Fig. 4, not by original theme " Folium Alangii " by other theme Supplement, but theme " Folium Alangii " self is amplified so that it is laterally highlight from holographic bar 14.

Therefore, observe in reflecting light time on front side of banknote (Fig. 6 a), only visible that highlight from holographic bar 14, rasterizing The part 70 of laser hole 32.Part 72 that covered by holographic bar 14, laser hole is due to holographic Figure 16, the dazzle (cross and irradiate) of 18 Invisible with the low contrast difference of metallization removal line 42 and line of cut 34, explain above in conjunction with Fig. 4 a.

Therefore, observer can see in reflection light and there is transparent theme, but observer not can recognize that its shape and information Content.Therefore, promote observer's backlight to hold banknote 10, and observe in transmission light.If so observing in transmission light, then see The person of examining obtains the eye impression of Fig. 6 b, and described eye impression shows complete theme " Folium Alangii " to observer.At transmission light In this image completely change the verity mark being impressive easy memory and easily being verified by anyone.

Although the present invention explains with the example of holographic bar 14 in embodiment so far, it will be appreciated that according to the present invention The Security element used not necessarily must comprise hologram.In the other structure according to the present invention, visual image Amendment is such as: the absorption of the thin layered element of the metallization removal of metal level, such as color inversion or reflecting layer, primer structure Metallization removal, the colour removal of color layer or partially or even wholly remove the other layer of Security element.Remove and can prolong at this Extend through whole Security element until the substrate of data medium, such as, extend in bank-note paper so that additionally create at this Watermark effect.In other structure, it is possible to the layer for Security element provides with laser sensitive marker material, described labelling material Expect to experience irreversible change, such as variable color by the effect of laser emission.

For diagram, Fig. 7 shows data medium 80 according to an embodiment of the invention in cross-section, wherein in paper substrates The Security element with metal level 84 is applied on 82.For forming fisrt feature identification division, in metal level 84 and paper substrates 82 The opening 86 run through is introduced by the effect of laser emission.Additionally, for forming second feature identification division, in modifier area 85 In the inherent identical course of processing and therefore in good registration, in the case of reducing laser power only in metal level 84 Introduce metallization removal line 88, wherein have modified the visual image of Security element.

In the embodiment in fig. 8, in modifier area 85, the laser power of reduction is adjusted to so that remove metal in generation When changing line 88, not only remove the metal of metal level 84, and in paper substrates 82, create thin position 90.Therefore, at transmission light During middle observation, modifier area 85 shows additional watermark effect.

Security element is such as removed by material or the amendment of variable color substantially allows the complexity usually used as pass through openings Design.Therefore, it is adapted so that the theme with more complicated and less complex theme part is by opening and modifier area Combination conversion.

This structure illustrates in the embodiment in fig. 9.Here, apply with metal level 102 in the paper substrates 100 of banknote Security element patch.According to inventive feature mark 104 be coat of arms theme and in fisrt feature identification division by paper The opening 106 of substrate 100 inner laser cutting is formed.In second feature identification division, signature identification 104 is by metal level 102 Interior multiple metallization removal lines 108 are formed, and wherein the visual image of Security element patch is modified.Feature mark in modifier area The higher complexity of knowledge 104 is directly visible with the metallization removal line 108 of the opening 106 relative to cut.Meanwhile, opening The line of cut of 106 the most mutually registrates on the position that they are connected with the metallization removal line 108 of metal level 102 so that Transmission light is given unified design.

Figure 10 shows the other enforcement of the data medium of the signature identification 114 produced with being applied by laser Example.It is similar to the embodiment of Fig. 9, the paper substrates 110 of banknote is applied with the Security element patch with metal level 112.Special Levying mark 114 is star theme in this embodiment, and described theme passes through in paper substrates 110 in fisrt feature identification division The opening 116 of cut is formed.In second feature identification division, signature identification 114 is gone by multiple in metal level 112 Metallized thread 118 is formed, and wherein the visual image of Security element patch is modified.The cutting of opening 116 and metallization removal line 118 Generation carried out by identical laser beam in the identical course of processing so that with the modifier area of metallization removal line 118 Ideally registrate with opening 116.In transmission light, pentagonal closure elements 118 will highlight in reflection light highlightedly Interior section 116 supplements as complete star theme 116,118.

In other structure, data medium comprises Security element, and the window being embedded in bank-note paper 120 of such as Figure 11 is prevented Pseudo-wire 122.The laser hole of the rasterizing including multiple parallel line of cut 126 is produced by applying laser in bank-note paper 120 124, the laser hole 124 of described rasterizing is overlapping with window anti-counterfeiting line 122.Laser parameter is chosen as at this so that laser emission removes The outer carrier thin film also wearing out anti-counterfeiting line 22 of bank-note paper 120.Then, first by the one or both sides in region of cutting respectively with separately Outer thin film covers.This combination can especially advantageously use in film composite banknote, be particularly used in " thin film/ Paper/thin film " Rotating fields film composite banknote in because the thin film of two outsides not only protects Security element 122 It is not modified and can prevent to pollute, and because this structure allows also to be manifested forgery attempt by the division of complex banknote, as Will be described in more detail below.

If the replacement as paper substrates 120 uses plastic-substrates, then described structure can be used on " thin Film/film/film " Rotating fields film composite banknote in.

Figure 12 shows another structure of data medium, simulates window anti-counterfeiting line with this.To this end, at the bank-note paper of banknote First applying the anti-counterfeiting line 132 linked up on 130, described anti-counterfeiting line 132 is provided with the metal level with characters cut in intaglio 134.Then, anti- That passes through laser emission in the range of pseudo-wire 132 acts on the multiple identical opening 136 of data medium internal cutting, wherein laser ginseng Number is chosen as so that bank-note paper 130 and anti-counterfeiting line 132 are cut in laser emission.Therefore, applied anti-counterfeiting line 132 He is passed through The combination of opening 136, defines the eye impression of window anti-counterfeiting line for observer.

The present invention can especially advantageously use in film composite banknote, and wherein external foil layer is simultaneously used for covering and leads to Cross opening produced by laser emission.This illustrates in figure 3 with general shape.Membrane according to the invention complex banknote 140 have the substrate 142 formed by paper or thin film, and described substrate 142 is connected with Security element 144.Then, substrate is being included With in the combination of Security element, identifying 150 by the effect introduced feature of laser emission, described signature identification 150 has thoroughly Penetrate the eye impression changed in light relative to reflection light.Fisrt feature identification division passes through at least one at this in substrate 142 Opening 152 is formed, and second feature identification division is formed by modifier area 154 in Security element 144, wherein Security element The visual image of 144 is modified by the effect of laser emission.

Because the amendment of Security element 144 is it is generally required to the energy consumption lower than the cutting of substrate 142, thus laser energy or Laser power generally reduces when guided laser bundle is transitioned into modifier area 154 from cutting zone 152, and on the contrary from amendment Region 154 raises when being transitioned into cutting zone 152.Ensure with this, although two its different signature identifications of signature identification part But to have the most perfect registration.

Finally, the Security element 144 of cut substrate 142 and amendment embeds between two thin film 156, in order to formed uncommon The film composite banknote 140 hoped.

Two outside thin film 156 can not only be protected from amendment and pollute, and also can be formed by cut Additional anti-false sign, described anti-false sign manifests forgery attempt (" distorting sign ") by splitting of complex banknote.I.e. If cutting the thin film of complex by laser and relatively deep scratching or even cut completely through substrate, then film composite banknote Split asymmetrically.Cut necessarily be formed the profile of closing for this.Therefore, on the banknote side do not cut by laser, protect Hold profile, and on banknote opposite side, define corresponding hole.If cut is in the region of other verity mark Introduce, then also damaged this mark when splitting.The most obvious operation attempt.

According in the structure of the present invention, line of cut 162 or the amendment line 172 of the laser hole 160 of rasterizing need not be forced Ground is straight and parallel, as used the most in the aforementioned embodiment and again illustrating in Figure 14 a.But, grid The laser hole 160 formatted can the most also comprise line of cut 164 that is straight and that dissipate or amendment line 174, as shown in Figure 14 b, Or comprise bending, equidistant line of cut 166 and amendment line 176, as in Figure 14 c illustrate, or also comprise bending, dissipate Line of cut 168 and amendment line 178, as shown in Figure 14 d.

When cut, the width of the amendment line in line of cut in the substrate and Security element is due to usual laser beam The Energy distribution of Gaussian and mutually different.The line of cut of all embodiments also can provide with the marginal area of laser amendment, As described by the most usually.

Certainly, even if the effect with reference to described by holographic bar or patch is in the most other Security element, such as, exist Can also use in the window of window line.Obviously, shown structure can the most at random combine.It is thus possible, for instance Figure 14 a to Figure 14 d That dissipate and/or bending line of cut can be with the Security element combination being described.
