Definitions
- the invention relates to security features - preferably for sealing,
- a security document which is provided with at least visually readable characters in transmitted light and is electrically conductive and has additional substances for machine testing is described in DE 40 41 025 AI.
- the security element preferably consists of a transparent film strip which has a visually verifiable negative writing and is additionally provided with electrically conductive and magnetic substances.
- Metallization coatings produced by printing are also known. Coatings produced using metallic printing inks allow a higher resolution depending on the type of printing - for example in the case of scatter prints. The choice of binder enables the setting of the partial sheet resistances. The brilliance of the surface is lower than the surface produced by the vacuum coating process.
- sealing is understood to mean sealing, enveloping, enclosing and welding in of documents, for example identity documents and personal documents.
- Areal metallization is understood to mean a homogeneously metallized area with a homogeneous surface brilliance.
- Scattering metallization means a non-homogeneously metallized surface or a homogeneously metallized surface with demetallizations or a homogeneously metallized surface with inhomogeneous surface brilliance or a homogeneously metallized surface with inhomogeneous surface brilliance and demetallizations.
- any material is referred to as the substrate or carrier substrate, onto or into which coding means are to be attached or inserted, material being understood to mean, for example, plastic or metal foils, laminates, papers, cardboard and textile fabrics.
- coding means are understood to mean means for securing and coding with electrical, optical or magnetic modes of operation.
- Components, coding means and electrically conductive layers which are connected in a different arrangement to a carrier substrate.
- Layers of known electrically conductive polymers are used.
- a prerequisite for the use of electrically conductive polymer layers in combination with a metallization layer is a clear difference between the surface resistances (»100 k ⁇ / D), in particular a very high electrical surface resistance of the metallization layer is required (» 200 k ⁇ / D).
- the customary and applied technologies for metallization achieve only low surface resistances.
- PEDT / PSS Polyethylenedioxythiophene polystyrene sulfonate
- a metallization layer is to be used as a technological hurdle for counterfeiters, the PEDT / PSS being characterized by a sheet resistance in the range of 15-100 k ⁇ / D.
- a surface resistance of 50 k ⁇ / D is achieved on PE films using a primer.
- the polymer layer is applied flat or partially, whereby it is preferably surface-modulated or applied as scatter pressure. Due to the partially changing surface resistance, a legible coding is created. This in turn can be easily detected in different ways, especially by means of capacitive coupling.
- a possible mechanical physical double test of the electrically conductive polymer PEDT / PSS is advantageous, which on the one hand detects the electrical conductivity and on the other hand the optical property, for example in the IR range.
- the TR properties can be used effectively with increasing wavelength (> 900 nm) and with the application weight or the layer thickness. Measurable parameters are given by absorption and change in wavelength. This double check significantly reduces the likelihood of identification of counterfeits or the error rate of the undetected counterfeits or the error rate of the real products identified as counterfeit.
- a metallized surface to be used according to the invention in particular with high brilliance, in which it would be assumed that it has good electrical conductivity, which could include an electrically conductive security feature or even represents a security feature via coded surface resistance changes - represents a further hurdle for a counterfeiter, since the task, function and mode of operation of the metallized surface are neither suspected nor obvious.
- the invention relates to security features, preferably for
- seals - Sealing, wrapping, enclosing and welding in documents - hereinafter referred to as seals - for the identification of their originality by authorized control bodies.
- the seals consist of substrates, of flat or scattered metallized applications with a defined surface resistance and of electrically conductive polymers, also with a defined surface resistance.
- the surface resistance of the flat or scattered metallized applications is greater than 200 k ⁇ / D and the surface resistance of electrically conductive polymers is in the order of 15 to 100 k ⁇ / D.
- the difference between the surface resistances of the applications and the electrically conductive polymer is larger than 100 k ⁇ / D.
- This type of seal according to the invention is associated with documents.
- the structure of the seals - that is, the arrangement of substrates, electrically conductive polymers, flat or scattered metallized applications, protective layers, release agents and / or adhesive layers - is selected depending on the purpose, the individual layers being interchangeable. Siliconized layers or transfer tapes or layers are preferably used as release agents. Depending on the intended use and the production technology used, primers are used, the primers both serving as adhesion promoters and, according to the invention, being suitable for smoothing applied substrates.
- the electrically conductive polymers, the flat or scattered metallized applications, the substrates, optionally also the protective layers and the primers are arranged according to the invention as coding means so that their electrical or optical or magnetic modes of action can be detected by means of capacitive coupling, that is to say they are used as coding means.
- the electrically conductive polymer to be used according to the invention is preferably a polyethylene dioxythiophene polystyrene sulfonate (PEDT P SS).
- a special embodiment of the invention provides for assembling sub-components to form a seal.
- the individual subcomponents can consist of substrates, of flat or scattered metallized applications and of electrically conductive polymers, it also being possible for the individual subcomponents to consist of protective layers, release agents, adhesive layers and primers.
- the selection and arrangement of the individual layers depends on the desired use and the processing technology. Different surface resistances of individual layers in the subcomponents are also within the scope of the invention.
- the subcomponents produced identically or with a different structure result in codings on their own or after their connection to form a seal. If encodings are only formed by assembling sub-components, their precise matching is an essential prerequisite.
- a seal 1 according to the invention is shown schematically as a section in FIG. It essentially contains a substrate 10, a surface or scattered metallized application or application layer 13 and an electrically conductive polymer 12 with a surface resistance of the order of 15-100 k ⁇ / D, the difference between the surface resistance of the surface or scatter metallized layer 13 and the sheet resistance of the electrically conductive polymer 12 is greater than 100 k ⁇ / D.
- the layers are optionally interchangeable.
- 1b shows the substrate 10 with a flat, metallized layer 13 with a sheet resistance greater than 200 k ⁇ / D, an electrically conductive polymer 12 - a polyethylene dioxythiophene polystyrene sulfonate - which is not visible to human vision - representing an identification number 20 and a security marking 21.
- FIG. 2a shows a further variant of a seal 1.
- a substrate 10 is smoothed with a primer 11.
- the electrically conductive polymer 12 is located on this, which in turn is provided with a primer 11 if necessary.
- This is followed by the metallized layer 13 and, if desired depending on the application, a final protective layer 14, wherein a primer 11 may also be required between the metallized layer 13 and the protective layer 14.
- a colored lacquer - not shown in FIG. 2a - can also be applied to the protective layer 14 for optical finishing. It is also conceivable that the protective layer 14 consists of such a lacquer layer.
- the position of the electrically conductive polymer 12 can be exchanged with the metallized layer 13.
- the primers 11 used can also act as adhesion promoters.
- the seal 1 contains an adhesive layer 15 for connection to documents. If the documents are introduced into the seal 1 - for example by welding, pressing or sealing a film as a covering for the documents - the adhesive layer 15 can be dispensed with.
- the seal 1 is usually wound on rolls, it makes sense to provide one side thereof with a release agent 9, in particular a silicone film.
- the seal 1 can also be provided with a transfer belt 16 (FIG. 2 c), the transfer belt 16 containing adjustment means 8, for example perforations, magnetic tracks or optical marks for the positionally accurate application of the seal 1 on the document. A modification of this is shown in Figure 2b.
- the substrate 10 is coated on both sides, with an electrically conductive polymer 12 on one side of the substrate 10 and the metallized layer 13 on the other side.

- the subcomponents 30; 31 seal, envelop documents or close, weld documents - such as ID and personal documents.
- One subcomponent 30 consists, in addition to other layers, of a substrate 10 and the electrically conductive polymer 12 and the other subcomponent 31 essentially consists of a substrate 10 and the metallized layer 13.
- the essential layers are Subcomponents 30; 31 interchangeable and the sub-components 30; 31 can be put together in different places.
- FIG. 3 a illustrates the schematic structure of a section of a seal 1 or a sub-component 30; 31.
- a coding is created due to the different thicknesses of the application and the resulting changing surface resistances.
- the modulated surface resistances represent a specific coding (see FIG. 3 a)
- Example 5 This example describes a seal 1 or a partial component 30; 31 similar to that described in Example 4, with the electrically conductive polymer 12 being partially applied. As shown in FIG. 3b, the partial applications of polymer 12 result in partially changing surface resistances, which in turn serve as encodings.
- Example 5
- a further embodiment of the seal 1 or a subcomponent 30 is varied from examples 3 and 4 with reference to FIG. 3c; 31 presented.
- the electrically conductive polymer 12 is partially applied and the respective sections of the partial orders are applied in a surface-modulated manner.
