  • the Raman effect is based on the scattering of electromagnetic radiation, in particular light, at a scattering center, wherein absorption of a portion of the incident radiation by excitation of rotations or vibrations of the scattering center takes place simultaneously with the scattered pulse change of the scattered radiation with respect to the incident radiation.
  • This energy transfer distinguishes the Raman effect from the Rayleigh scattering, in which no energy transfer takes place, but only a scattered pulse change.
  • Raman spectroscopy A further development of Raman spectroscopy is the so-called surface-enhanced Raman spectroscopy (SERS).
  • SERS surface-enhanced Raman spectroscopy
  • an amplification of the Raman signal by a factor of 10 6 to 10 12 achieved in that the scattering centers are brought into contact with certain rough metal surfaces, typically metallic nanoparticles, such as Ag, Au, or Cu nanoparticles.

  • This effect is associated with the resonant excitation of surface plasmons.
  • An overview of the electromagnetic theory of SERS and the various processes involved can be found, for example, in the reference M. Moskovits, Journal of Raman Spectroscopy 36: 485-496 (2005).
  • US Pat. No. 9,995,839 discloses a scanning system for Raman examination of documents, wherein the materials normally used in the document are identified on the basis of the Raman signal and thus the document is verified.
  • the SERS effect is used, for example, in particles described in US-2002/0104762. These can be formed, for example, as nanobar codes, wherein the particles are formed as a few microns long rods, which are composed of layers of different materials and thereby form the barcode. When measuring with sufficient local resolution ( ⁇ l ⁇ m), the barcode can be read out.
  • the rods can be coated with a reporter substance to increase sensitivity and selectivity, resulting in an intense and environmentally independent signal or signal sequence. Such Particles are discussed for use in product protection.
  • the invention is based on the technical problem of specifying a security and / or value document which can be examined and verified in a particularly simple manner by means of SERS and without changing the security and / or value document.
  • the invention is based on the further technical problem of specifying a security and / or value document whose analyzability with SERS is not limited to the surface.
  • the invention is based on the technical problem of providing a particularly simple and inexpensive security and / or valuable document which can be verified by means of SERS.
  • the invention teaches a security and / or value document containing at least one security feature which in a defined spatial position in the security and / or
  • Value document is attached and contains SERS-active particles, wherein the particles are in direct contact with a Raman-active polymer of a polymer layer or a print layer of the security and / or value document.

  • security and / or value documents typically have a substrate, a printing layer and optionally a transparent cover layer.
  • a substrate is a support structure to which the print layer is applied with information, images, patterns, and the like.
  • a substrate may be single-layered or multi-layered. Suitable materials for a substrate or a substrate layer are all customary materials based on paper and / or plastic in question.
  • a security feature is a subarea (area or volume) of the security and / or value document that can be used to verify the security and / or value document.
  • the subarea can be structureless, but it can also be a pattern.
  • Such a pattern may be a similar pattern for different security and / or value documents.
  • the pattern is suitable for verification of one type of security and / or valuable document. Examples of such document type-specific lateral patterns are: seals, coats of arms, regular or irregular surface patterns, such as line coats or guilloches, ID and 2D barcodes. This may be visible or um Under normal light, non-visible patterns, where the invisible patterns differ from the visible patterns in that the non-visible patterns first become visible by technical means such as UV source.
  • the pattern can also be an individual pattern for different security and / or value documents (of the same document type), which pattern is coded in particular for identification information of the security and / or value document. For example, for individual patterns come the following
  • coded data alphanumeric strings, such as personal records, pieces of personal records, such as names, forenames, address, date of birth, place of birth, and / or document data, parts of document data, such as

  • SERS-active particles are particles which, on contacting the particles with a substance to be examined by Raman spectroscopy, have an increased signal intensity of at least 10 3 , in particular by at least 10 5 , compared with a Raman signal on the substance without contact with SERS active particles. It is essential to understand that the intensity of an SERS signal is by no means a function of the concentration or density of the SERS active particles. If a SERS signal is obtained due to a SERS-active particle, the addition of further SERS-active particles does not result in a significant increase in the SERS signal. Reference is additionally made to the reference M. Moskovits, Journal of Raman Spectroscopy 36: 485-496 (2005).
  • the security and / or value document remains completely unchanged as a result of the examination of the security feature and can still be used.
  • This can also be a repeated examination of the security feature or the security and / or
  • Value documents are made without any changes of the security and / or value document, in contrast to the known preparation of the security and / or value document with a colloidal solution. As a result, the expense of a preparation with the associated waiting time is avoided by the invention. Verification can be quick and easy.
  • the positioning of the security feature or its examination is not limited to the surface of the security and / or value document. Rather, the security feature can be arranged at any point of the security and / or value document, even in the volume. Thus, the security feature can be set up in the substrate, in a printing layer or in a generally transparent cover layer of the security and / or value document.
  • the SERS-active particles are introduced at the desired location or layer for the security feature, which is easily possible in the course of the production process of the substrate or a print layer or cover layer.

It should be noted that SERS-active particles are typically clusters of nanoparticles (with a volume of up to 10 9 nm 3 ) of the metals concerned.

  • a Raman active material may be a synthetic organic polymer having one or more functional groups (such as, but not limited to, carbonyl, carboxyl, hydroxy, thiol, ether, thioether, nitro, nitroso, sulfonyl, sulfo, Phospho, phosphonyl, amino, etc.).
  • the functional group or functional groups may also be, for example, aromatics, conjugated aromatics and heterocycles, such as quinolinyl, dioxanyl, furanyl, imidazolyl, indolyl, morpholinyl, oxazolyl, oxiranyl (ethylene oxide),
  • a security feature there are various possibilities. It can be simple or multiple. With multiple devices, the security features may be the same or different with respect to the SERS signal. Various security features are obtained, for example, in that the SERS-active particles in different matrices of the security and / or value document are embedded.
