Definitions
- the invention relates to security documents with multilayer security markings.
- Protected documents can be valuable documents, such as checks, stocks, banknotes, excise stamps, special federal stamps and identification documents, such as passports, identification cards, etc.
- Identification documents such as passports, identification cards, etc.
- security documents are usually provided with security markings such as watermarks, holograms, diffraction-refractive nanograms, fluorescent signs, security threads, etc.
- the present invention is directed to the creation of such protective markings that are able to provide unusual optical effects that occur without the use of special equipment.
- Protective elements based on micro-lens raster structures are known. Optical images in such protective elements are formed as a result of superposition of two or more microraster structures, one or more of which is microlens gratings, the others are raster structures made with the same spatial periods as microlens gratings, in the nodes of which there are repeating micro images made using printing technologies or precision stamping technologies. In these cases, the so-called moire effects are used. There are several types of such effects. Moiré effects with orthogonal or collinear (parallel) parallax shift of the observed magnified optical images. This type of moire effects is characteristic of microraster structures with spherical or pseudo-spherical lenses in the nodes of the raster lattices.
- a micro-optical system is described (US 2005/0180020 A1, 08/18/2005), in the form of a polymer film, which when viewed with the naked eye in reflected or transmitted light, projects one or more images that demonstrate various visual effects, such as: orthoparallactic movement; images appear to lie deeper in the spatial plane than the thickness of the polymer film; seem to lie in the spatial plane above the surface of the polymer film; vibrate between the spatial plane deeper than the thickness of the polymer film and the spatial plane above the surface of the film, as the film rotates azimuthally; are transformed from one type, shape, size, color (or a combination of these properties) into another type, shape, size or color; seem to have realistic three-dimensionality.
- the films in this security element are very resistant to tampering due to their complex multilayer structure and their elements with a high aspect ratio.
- Another use of microlenses allows the formation of the so-called vario-stereo effects. This is achieved by using linear (lenticular) celindric micro-raster lens structures.
- printed or embossed images are formed at a distance of the order of three focal lengths from the plane of the lenticular raster and are not a lattice of microimages, as in the above case, but are formed by specially combining several printed or embossed images (ordinary, non-micro raster lattice images) .
- Each image is divided into stripes with a width of the order of the period of the lenticular raster, and through the strip with the given law, the changes in the symmetry in the stripes are combined into one single image.
- various images will be visible at different angles, which forms vario- or stero-effects, including the formation of motion effects observed images. In these systems, optical moire magnification will not be observed.
- microlenses One of the main disadvantages of microlenses is the location of the lenses on the outer surface of the protective element (they cannot be covered with any protective layer, otherwise the necessary optical effects will be lost). This leads, firstly, to fast and uncontrolled wear (abrasion) of the raster, and, secondly, to the possible appearance of transparent layers of liquid, fat, etc. on the surface of the raster. The quality of the observed variable images deteriorates sharply, or the images completely disappear.
- Protective elements are also known that use holographic methods for creating changing images of observables when changing the direction of observation and lighting of the protective element (RU 2345900 C2, 02/10/2009).
- several holographic images are formed on the surface or in the volume of the security element using various reference optical frequencies (gratings).
- gratings reference optical frequencies
- the contrast and brightness of the observed images deteriorate, the movement of images becomes fuzzy and difficult to distinguish.
- Observation of images is complicated by their "rainbow" character, arising from high spatial frequencies gratings and diffraction of incident non-monochromatic light on them. It is necessary to apply special measures to increase the contrast, brightness, clarity of the observed images and provide conditions for more reliable fixation of their changes (movements).
- the problem solved by the invention and the technical result is to increase the security of products by creating a new optical effect that increases the recognition of the protected object, based on the observation of mutual movements of images when changing the viewing angle.
- a multilayer protective element containing a flexible carrier layer with optically variable structures containing two or more groups of repeating images that move and / or change with a change in the viewing angle is characterized by that optically variable structures are formed in such a way that when changing the viewing angle, different groups of images move relative to each other.
- the multilayer security element is also characterized by the fact that the movement of images belonging to different groups occurs parallel to the plane of change in the viewing angle, so that the images approach or are removed relative to the observer, the movement of images related to different groups occurs perpendicular to the plane of change viewing angle, so that the images move to the right or left of the observer, the movement of images belonging to different groups occurs in different axial directions
- the movement of images belonging to different groups occurs parallel to the plane of change in the viewing angle or the movement of images belonging to different groups, it is combined with a smooth change in the geometric parameters of the images, for example, the angles of inclination to the longitudinal axis of the protective element or their linear dimensions.
- the multilayer security element may be in the form of a strip, or a local thin-film element, a security thread, or a thin-layer film coating structure.
- a document protected from forgery such as a check, a stock, a banknote, an excise stamp, a special federal stamp, a passport, an identification card and other similar products, includes at least one security element described above .
- a document protected from forgery is characterized in that the security element is made in the form of a strip or a local thin-film element placed on the surface of the document to be protected or the security element is made in the form of a thin-layer structure covering the document or the security element is made in the form of a security thread inserted into protected document.
- the essence of the invention lies in the fact that the protective element containing a flexible carrier layer with optically variable structures containing two or more groups of repeating images that move and / or change when the viewing angle changes, and according to the invention, optically variable structures are formed in such a way that when changing the viewing angle, different groups of images that are closely spaced to each other at a distance of the order of the size of the visible images move relative to each other.
- the movement of images belonging to different groups occurs parallel to the plane of change of the viewing angle, so that the images approach or are removed relative to the observer, or the movement of images belonging to different groups occurs perpendicular to the plane of change of the viewing angle , so that the images move to the right or left of the observer, or the movement of images belonging to different groups occurs in different axial directions with respect to -plane variation of the angle of observation or images belonging to different groups, combined with a smooth change of geometric parameters of images, for example, angles of inclination to the longitudinal axis of the protective element or their linear dimensions.
- Optically variable structures contain microlens raster structures, diffraction-refractive structures, or holographic structures.
- a document protected from forgery such as a check, a stock, a banknote, an excise stamp, a special federal stamp, a passport, an identification card and other similar products, contains the security element described above.
- the security element may be in the form of a strip, or a local thin-film element placed on the surface of the document to be protected, or a thin-layer film structure covering the document to be protected, or a security thread inserted into the document to be protected.
- FIG. 1 presents options for changing images formed by holographic threads at different viewing angles, that is, The process of the change (movement) of the Si and S 2 symbols described above is illustrated.
- FIG. Figure 2 shows photographs of holographic images observed at different angles formed on a real security element made in the form of a holographic thread.
- the symbols Sj and S 2 the digits "100" were selected located at a certain distance (1-2 mm) from each other along the thread and changing their visible location and orientation depending on the viewing angle.
- a rainbow holographic relief is created on the surface of the holographic foil, which, when viewed visually, forms, at a certain viewing angle ao, an image of two Si and S 2 symbols located at some IQ distance from each other .
- the observation angle ao by some angle ⁇ the observed image is changed so that the distance between the characters increases by ⁇ . If the viewing angle is increased by another ⁇ , the distance between the symbols will increase to ⁇ + 2 ⁇ . With a further increase in the observation angle by ⁇ , a corresponding increase in the distance between the observed symbols by ⁇ occurs.
- the optical variable structure based on the rainbow holographic element in Example 1 it is possible to form floating images with the multidirectional movement of their fragments in diffraction-refractive structures in the form of a combination of Fresnel lenses combined with each other or in the form of a thin-film nano-prismatic system of diffractive optical elements.
- the formation of floating images is carried out by structures obtained by embossing with master matrices made by precision engraving of concentric annular grooves (grooves) of a given profile, forming a system of Fresnel lenses intersecting with each other.
- the engraving resolution characteristic dimensions of the groove profile
- the structure forming floating images is created using electronic, ion, or laser nanolithographs with a resolution of the order of 10-100 nm.
- the structure is nano-sized tubercles and pits distributed according to a given law.
- Floating images with multidirectional movement of groups of individual fragments can also be organized in optical elements based on structures with micro-lens rasters and systems of micro-image gratings.
- the nature of the observed motion of enlarged moire images is determined by the parameters and orientation of the microimage lattices and micro lenses.
- certain local portions of the microimage raster with sizes of the order of 10-100 spatial periods are left free of microimages. Upon observation, these areas will appear to be floating above a plane with moving enlarged images of microimages, i.e. the apparent multidirectional movement of such local areas with respect to moving remote background images will be formed.
- This invention allows to simplify the process of identifying falsified and fake documents, as it allows to increase the security of products by creating a new optical effect that increases the recognition of the protected object, based on the observation of mutual movements of images when changing the viewing angle.

Abstract
L'invention concerne des documents protégés contre les contrefaçons et comportant des marquages de protection multicouche. L'élément de protection multicouche comprend une couche porteuse flexible avec des structures optiques alternantes comportant deux groupes ou plus d'images qui se répètent, et qui se déplacent et/ou changent lorsque l'on modifie l'angle d'observation. Ces structures optiques alternantes sont formées de sorte que lorsque l'on modifie l'angle d'observation, différents groupes d'images se déplacent l'un par rapport à l'autre. Cette invention permet d'augmenter le niveau de protection d'articles du fait de la génération d'un nouvel effet optique qui augmente les capacités d'identification de l'objet à protéger en se fondant sur l'observation des mouvements réciproques des images lors du changement de l'angle d'observation.
