Definitions
- the invention relates to a security element for security papers, valuable documents and the like having two superimposed layers of cholesteric liquid crystalline material which selectively reflect light from a first, longer wavelength spectral range respectively in a first viewing direction perpendicular to its surface and in a second viewing direction at an angle to reflect perpendicular to its surface selectively light from a second, shorter-wave spectral range.
- Valuables such as branded goods or value documents, are often provided with security elements for safeguarding purposes, which allow a check on the authenticity of the object of value and at the same time serve as protection against unauthorized reproduction.
- security elements for safeguarding purposes, which allow a check on the authenticity of the object of value and at the same time serve as protection against unauthorized reproduction.
- the special properties of liquid-crystalline materials are exploited for this purpose, and above all the viewing angle-dependent color impression of liquid crystal layers, which is referred to below as the color-shift effect.
- the color shift effect of a single liquid crystal layer always leads to a shift of the reflected light wavelength from a longer wavelength range to a shorter wavelength range when the liquid crystal layer is tilted out of the perpendicular viewing direction.
- document EP 0 720 753 B1 describes a colored material with two chiral liquid-crystal polymer papers arranged one above the other, one leaflet being viewed in the case of tion perpendicular to its surface infrared light and reflected when viewed at an angle to the perpendicular to its surface red light.
- the second leaflet when viewed perpendicular to its surface, reflects blue light and, when viewed at an angle to the normal to its surface, reflects ultraviolet light.
- the object of the invention is to avoid the disadvantages of the prior art and, in particular, to specify a security element of the type mentioned at the outset with a conspicuous visual tilt effect and high counterfeit security.
- a first of the two liquid crystal layers is present in the form of a motif to be displayed and reflects light in the first viewing direction from the green spectral range, and that
- the second of the two liquid crystal layers reflects light from the green spectral region in the second viewing direction.
- the inventive coordination of the color shift effects of the liquid crystal layers on the dependence of the sensitivity of the human eye on the wavelength of light allows a surprising and visually spectacular tilting effect:
- the motif to be displayed appears for a viewer with bright green a clearly contrasting background. If the observer tilts the security element out of the vertical in an oblique viewing direction, the motif disappears and the image impression appears to be a uniform green surface without any recognizable contrast differences.
- the green spectral range encompasses all wavelengths which produce a substantially green color impression in the viewer.
- the first layer is formed so that it in the first viewing direction light from the wavelength range between 490 nm and 590 nm, more preferably between 520 nm and 570 nm.
- the second layer is preferably designed such that it reflects light in the second viewing direction from the wavelength range between 490 nm and 590 nm, particularly preferably between 520 nm and 570 nm.
- the first layer is designed such that it reflects light from the blue or ultraviolet spectral range in the second viewing direction.
- the second layer advantageously reflects light from the 'red or infrared spectral range in the first viewing direction.
- the two layers are expediently arranged on a carrier, wherein in a first variant of the invention the first layer is arranged below the second layer.
- the sequence of the two liquid crystal layers plays no role for the effect according to the invention, so that alternatively the first layer can also be arranged above the second layer.
- the support preferably contains a light-absorbing background.
- the support may contain a dark, for example, black background, or, in order to be able to influence the color impression of the liquid crystal layers in a targeted manner, also a light-absorbing colored background.
- a support with a light-diffractive background, in particular with a diffractive black background, is also considered, as the color effect of the liquid crystals is also emphasized by such a background.
- at least one of the two liquid-crystalline layers is applied over the whole area as a film coating and optionally structured in the form of a motif.
- at least one of the two liquid-crystalline layers is formed by printing liquid crystal pigments embedded in a binder matrix.
- the security element contains at least one further security feature, in particular a layer with magnetic, electrically conductive, phosphorescent, fluorescent or other luminescent feature substances or a polarizing or phase-shifting layer.
- the further layer can be arranged above, below or between the two layers of liquid-crystalline material.
- security elements according to the invention are not limited to designs with two liquid crystal layers, but rather that additional liquid crystal layers may be provided to achieve additional effects or effects.
- the invention also encompasses a method for producing a security element for security papers, documents of value and the like, in which two layers of cholesteric liquid-crystalline material are arranged one above the other, each selectively irradiating light from a first, longer-wave spectral range in a first viewing direction perpendicular to its surface in a second viewing direction at an angle to Vertical to its surface selectively reflect light from a second, shorter-wave spectral range, wherein the method
- a first of the two layers is generated in the form of a motif to be displayed and is formed such that it reflects light from the green spectral range in the first viewing direction, and
- the second of the two layers is formed so that it reflects light from the green spectral range in the second viewing direction.
- the invention further comprises a data carrier, in particular a value document, such as a banknote, an identity card or the like, which is equipped with a security element of the type described.

- a first of the two liquid crystal layers is present in the form of a motif to be displayed and reflects light from the green spectral range in the second viewing direction, and
- the second of the two liquid crystal layers reflects light from the green spectral region in the first viewing direction.
- the second layer is designed such that it reflects light from the blue or ultraviolet spectral range in the second viewing direction.
- the first layer reflects into the first viewing direction with advantage light from the red or infrared spectral range.
- the motif in plan view (first viewing direction) can not be recognized because the second layer reflects light from the green spectral range in the first viewing direction, the first layer light from the red or infrared spectral range reflected in the first viewing direction and the human eye is much more sensitive to green light. It thus appears to the viewer in the first viewing direction, a uniform green area without apparent contrast differences, while tilting the security element from the vertical in an oblique viewing direction, the green motif to be displayed against a contrasting blue background appears.
- the effect according to the invention is based on the coordination of the color shift effects of the two liquid crystal layers on one another and on the spectral sensitivity of the human eye, which will be explained in more detail below.
- a first of the two layers is generated in the form of a motif to be displayed and is formed such that it reflects light from the green spectral range in the second viewing direction, and
- the second of the two layers is formed so as to reflect light from the green spectral region in the first viewing direction.

- the second liquid crystal layer 24 is arranged over the entire surface of the first liquid crystal layer 22 in the exemplary embodiment.
- the second liquid crystal layer may itself also be in the form of a motif as long as it provides only a background for the motif of the first liquid crystal layer.
- the liquid crystal layers 22, 24 can first be applied over the whole area as a film coating, wherein at least the first liquid crystal layer 22 is structured after application by known methods in the form of the motif to be represented.
- the liquid crystal layers may also be formed by printing liquid crystal pigments embedded in a binder matrix.
- alignment layers may be provided between the background 20 and the first liquid crystal layer 22 and / or between the two liquid crystal layers 22 and 24.
- the security element is not necessarily produced by directly applying the layers to a suitable data medium. Rather, it is also possible to use a so-called transfer method in which z. B. at least the two liquid crystal layers on a suitable substrate, for. As a film applied, then provided the outer layer with an adhesive layer and using the adhesive layer, the two layers on a absorbing the background are applied to a disk. Subsequently, the film is peeled off and the security element is arranged on a data carrier with the layer sequence shown in the figures.
- transfer methods are known to the person skilled in the art with which a data carrier according to the invention can be obtained.
- the cholesteric liquid crystal layers 22, 24 each have a defined color shift effect, ie they selectively reflect light from a first, longer wavelength spectral range in a first viewing direction perpendicular to their surface and reflect in a second viewing direction at an angle to the perpendicular Their surface selectively light from a second, shorter-wave spectral range.
- the effect according to the invention is based on the coordination of the color tilting effects of the two liquid crystal layers on one another and on the spectral sensitivity of the human eye. It is exploited that cholesteric liquid crystal layers reflect circularly polarized light in the relevant spectral range with a reflectance of up to 50%. In the longer wavelength range, the bands become wider and the height of the reflection maximum decreases slightly. Overall, however, the amount of light reflected in the optical range remains approximately the same.

- a high-contrast picture impression results for the viewer as a whole, as illustrated by FIGS. 2 and 3 (a).
- the overall color impression 40 is determined solely by the red light 30 reflected by the second liquid crystal layer 24 in the first viewing direction, so that the background 50 of the security element 12 appears red.
- the overall color impression 42 results from the superimposition of the red light 30 reflected from the second liquid crystal layer 24 and the green light 34 reflected from the first liquid crystal layer 22. From comparison to green light For the viewer, the green color impression of the first liquid crystal layer 22 is dominated by the significantly higher spectral sensitivity of the human eye to red light, so that the interior of the coat of arms motif 52 appears in bright, glowing green.
- the overall color impression 44 is again only by the green reflected by the second liquid crystal layer 24 in the viewing direction
- Light 32 determines that background 54 of security element 12 will appear green when viewed obliquely.
- the overall color impression 46 results from the superposition of the green light 32 reflected by the second liquid crystal layer 24 and the blue light 36 reflected by the first liquid crystal layer 22 Compared to blue light significantly higher spectral sensitivity of the human eye dominates for the viewer the green color impression of the second liquid crystal layer 24, so that the inside of the coat of arms motif 56 likewise appears green.
- both the area of the coat of arms motif 56 and the background area 54 thus appear green, so that the image motif disappears for lack of contrast for the viewer.
- the tilted security element 12 presents itself to the viewer as a uniform green area, as illustrated in FIG. 4 (b).
- a layer 64 of cholesteric liquid-crystalline material is printed on an absorbent colored background 66, which, like the second liquid-crystal layer of the embodiment of FIGS. 2 to 4, has a color-shift effect from red to green.
- a further layer 62 of cholesteric liquid-crystalline material in the form of the motif to be displayed is then printed.
- the further layer 62 has, as the first liquid crystal layer of the embodiment of Figures 2 to 4, a color shift effect of Green to blue.
- the illustrated motif also highlights in contrast with this security element in supervision and disappears when tilting the security element.
- the color impression can be influenced in a top view and in an oblique view.
- liquid crystal layers described can be combined with further layers which serve, for example, the protection of the security element or one of its partial layers, improved alignment or adhesion of the layers or a further increase in the security against counterfeiting.
