- FIG. 3 shows a security element 1 which is formed with at least one third region 9 with third structures 10, which third structures 10 are covered by a layer with color-shifting pigments, in particular interference pigments, pigments with a color-shifting thin-layer structure 11 or liquid crystal pigments, or by a Layer with a color-shifting thin-film structure 11 are formed, and/or that the third structures 10 are formed by at least one liquid crystal layer, in particular a cholesteric liquid crystal layer, and/or that the third structures 10 are formed on a side facing away from the visible side 23 with at least one one Color shift effect-enhancing layer are formed, and / or that the third structures contain 10 metallic pigments and / or magnetic pigments and / or color pigments and / or dyes, and which third structures 10 reproduce third information, with the first region 2 and the third area 9 and/or the second area 4 and the third area 9 overlap at least in sections.
- a layer with color-shifting pigments in particular interference pigments, pigments with a color-shifting thin-layer structure
- the arrangement or application of the third structures 10 or components or partial layers of the third structures 10 to the security element 1 or to the first structures 3 and/or second structures 5 can be effected, for example, by a printing process and/or a vapor deposition process or by several of the same.
- the exemplary embodiment according to FIG. 3 is designed with a color-shifting thin-layer structure 11 .
- the color-shifting thin-film structure 11 can have at least one absorber layer 18 and at least one spacer layer 19 made of a dielectric material.
- the thin-layer structure can have at least one reflection layer 20 , with the spacer layer 19 being able to be arranged between the reflection layer 20 and the absorber layer 18 .
- the reflection layer 20 can overlap the carrier layer 6 in sections or over the entire surface. It may be the case that the reflective layer 20 acts as a reflective layer 16 between the carrier layer 6 and the first structures 3 and second structures 5, or between the carrier layer 6 and the layer 14 with the first structures 3 and/or second structures formed therein 5 is formed.
- a color-shifting thin-film structure 11 is at least partially superimposed on the first structures 3 and/or the second structures 5 .
- a possible embodiment is shown by way of example in FIGS. 7a and 7b. In this case, both the first structures 3 and the second structures 5 are partially covered by the thin-film structure 11 .
- different layer sequences are conceivable or expedient. For example, as shown in FIG. 7a, a structure with a sequence described from bottom to top “layer 14 with first 3 and/or second structure 5 embossed therein—reflection layer 20—spacer layer 19—absorber layer 18” can be provided.
- the security element 1 in FIG. 3 has no additional layer 14 applied to the carrier layer 6, into which the first structures 3 and second structures 5 are introduced.
- the first structures 3 and second structures 5 are introduced or embossed directly into the carrier layer 6 in FIG.
- the security element 1 can also have additional layers 21, which additional layers 21 include in particular protective lacquers, heat-sealing lacquers, adhesives, primers and/or foils.
- additional layers 21 include in particular protective lacquers, heat-sealing lacquers, adhesives, primers and/or foils.
- a layer 21 can be formed as a cover layer on a visible side 23 of the security element 1 .
- Figures 4 and 5 each show a section through two further exemplary embodiments of security elements 1 with a security or security paper 22.
- FIG. 4 shows that the security element 1 is arranged on a security document or security paper 22 with its side of the carrier layer 6 facing away from the visible side 23 .
- An additional layer 21 is formed on the side of the carrier layer 6 facing away from the visible side 23, which additional layer 21 can be formed as an adhesion layer or as an adhesive layer.
- a reflective layer 16 is formed on the visible side 23 of the security element 1 , the first structures 3 and the second structures 5 being coated with the reflective layer 16 .
- a layer 21 as a protective layer can be provided as the top layer, i.e. as the outermost layer viewed from the visible side 23, which protects the entire layer and/or layer structure from mechanical damage such as scratches, grooves or the like.
- a layer 21 designed as a protective layer does not form the outermost layer of the layer structure, but that this is covered by a layer 21 designed as an adhesion or adhesive layer.
- the layer 21 embodied as a protective layer--as shown by way of example in FIGS. 3 and 4--a planar configuration of the security element 1 can preferably also be achieved.
- a layer 21 designed as a protective layer follows a contour of the structures 3, 5, 10. This is shown in FIG.
- the carrier layer 6 can advantageously also fulfill the functions of a layer 21 designed as a protective layer.
- a layer 21 designed as a protective layer can also additionally be located between the first and second structures 3, 5 and the carrier layer 6 or between the reflective layer 16 and the carrier layer 6.
- the security element 1 can thus be applied to the security document or security paper 22 with its side facing away from the visible side 23 .
- an additional layer 21 can optionally be formed, which additional layer 21 can be formed as an adhesion layer or as an adhesive layer.
- FIG. 6 shows a roughly schematic process sequence for producing a security element 1 for a security or security paper 22 .
- the method outlined is particularly suitable for producing a security element according to one of claims 1 to 18.
- the method initially provides that an impression element 17 comprising first structures 3 and second structures 5 is provided.
- the first structures 3 are designed in such a way that they reflect a first piece of information in different spatial regions, so that a movement image is created for an observer with a corresponding movement of a light source 8 and/or with a change in an observation angle, with movement of the light source 8 and/or change of the observation angle, a movement of the first piece of information occurs at the same time.
- the second structures 5 reproduce static and/or viewing angle-independent second information. Furthermore, a carrier layer 6 is provided. Alternatively, as shown in the figure, a carrier layer 6 comprising a layer 14, in particular an embossing lacquer layer, can be provided. According to the invention, the first structures 3 and the second structures 5 are also molded into the carrier layer 6 or into the layer 14.
- an impression element 17 or master is formed with first structures 3 with a movement effect, such as micromirrors, and if a second impression element 17 or a second master has static and/or viewing angle independent, in particular diffusely scattering, second structures 5 is formed.
- a movement effect such as micromirrors
- second impression element 17 or a second master has static and/or viewing angle independent, in particular diffusely scattering
- second structures 5 is formed.
- These two masters can be copied and duplicated any number of times and placed side by side in any convenient way.
- An arrangement on a molding device 12, such as an embossing roller 13 or a shim, and subsequently embossing into a particularly UV-curable layer 14 or embossing lacquer layer can take place.
- an impression element 17 or master with first structures 3 is provided and if the second structures 5 are introduced in or also next to these first structures 3, for example by means of laser ablation.
- a master produced in this way can also be reproduced in one or more subsequent steps, the execution of such copying steps from the positive to the negative and vice versa being fundamentally familiar to those skilled in the art.
- an arrangement on a molding device 12 such as an embossing roller 13 or a shim and an embossing of the first and second structures 3, 5 can take place in a particularly UV-curable layer 14 or embossing lacquer layer.
- FIGS. 2 to 5 show further processing steps, it being noted at this point that the invention is not limited to the specifically illustrated variants of the same, but rather also various combinations of the individual design variants are possible with one another and this possibility of variation is within the ability of the person skilled in the art working in this technical field on the basis of the teaching on technical action through the present invention.
