Definitions
- the present invention relates to the field of security elements used for authentication and / or identification of articles, documents or various objects.
- security elements applied on the surface or introduced in bulk or in windows in a security article, in particular a security article.
- security document, or other object for example a label, packaging, especially for drugs, food, cosmetics, electronic parts or spare parts.
- the security article may in particular be chosen from among a means of payment, such as a bank note, a check or a restaurant ticket, an identity document such as an identity card, a visa, a passport or a driving license, a lottery ticket, a ticket or a ticket to events.
- a means of payment such as a bank note, a check or a restaurant ticket
- an identity document such as an identity card, a visa, a passport or a driving license, a lottery ticket, a ticket or a ticket to events.
- No. 6,286,873 teaches the possibility of observing coded images on each side of an optical system comprising a revelation frame and a combined image located on either side of a substrate.
- US 2007/0279697 discloses a security element having an optical system for producing a moiré effect.
- security elements comprising an optical system capable of producing optical effects that can contribute to the authentication or identification of an article or object, and the possible incorporation into an article or object such as that a paper can be done relatively easily.
- a security element comprising:
- an optical system comprising:
- the combined image may include at least two nested encoded images.
- it comprises at least three nested coded images in order to accentuate the visual animation effect during successive observations of the coded images by changing the observation direction of the security element relative to the optical system.
- the revelation of the coded images can be done by parallax effect.
- the invention offers new possibilities to authenticate and / or identify an article or object carrying the security element, for example a security document.
- the user can, by varying the inclination of the optical system, show a succession of images, which can create an animation effect for example.
- the revelation frame may allow the human eye to visualize a different coded image at a time, the observer's brain being able to reconstitute for example a motion or observe hidden information.
- the presence of metal layers on the revelation screen and / or on the combined image may allow the appearance of metal effects when the user opts for the inclination of the optical system.
- the metallic effect may, for example, reveal silvery, golden, coppery reflections, among others, depending on the metal.
- the separate observation of the revelation screen or of the combined image can reveal a first matt color (with non-metallic renderings), silver or gold for example, while the superimposition of the revelation screen and the combined image may show metallic reflections of the same or another color depending on whether the revelation screen and the combined image are respectively of the same color or of different colors. This is explained in particular by the fact that a minimum continuous metal surface is necessary to obtain the desired metallic (shiny) effect.
- the metal layers on the revelation screen and / or on the combined image may appear matte, that is to say without metallic effect.
- Such an effect makes it possible, for example, to bring clarity to the security element without its observation being disturbed by metallic reflections.
- Such an effect is for example obtained when the combined image is placed above the revelation frame on the side of the observer. More generally, the metallic effect is less when the combined image is placed above the revelation frame, on the observer's side.
- the invention can make it possible to reveal metallic effects which are attractive to the user and effective for use as a safety element.
- the security element can provide anti-photocopying security.
- the fineness of the revelation screen and / or the combined image especially less than 200 microns, can prevent reproduction by photocopying and also provide protection against the use of scanners.
- the anti-photocopy security can be double because it can be provided both by the fineness of the revelation screen and by the reflective, glossy and metallic appearance of the security element which is not reproducible by photocopy.
- the resolution of the combined image and / or the revelation frame can be directly related to the thickness of the substrate. It may be greater than or equal to 800 dpi, preferably greater than 2000 dpi and more preferably greater than 3000 dpi.
- the revelation screen and / or the combined image can be as such of homogeneous appearance to the naked eye, given its fineness.
- the revelation screen may appear to the naked eye as having an appearance, in particular a uniform color, for example silvered or gold-colored depending on the metal chosen to produce the revelation screen.
- a metal frame and / or a metallic image can bring clarity to the security element while ensuring an opacity equivalent to a frame and / or an image made with a non-reflective ink.
- the metal layer carried by the revelation screen and / or the combined image can reflect the light and thus bring more clarity to the image.
- the security element can be not only pleasant and interesting for the general public, but also easily visible and attractive, thus allowing easy and intuitive authentication by the general public.
- the different images that the observer can see are other than images resulting from a phenomenon of spatial interference between two superimposed networks, in other words a moiré effect.
- a phenomenon of spatial interference between two superimposed networks in other words a moiré effect.
- Such an effect can result from an offset orientation of the superimposed arrays by a non-zero specific angle and can disappear when the arrays are exactly superimposed or are shifted by an angle different from the specific angle.
- the invention preferably seeks to avoid such an effect.
- the transition from observation of one coded image to another when the viewing angle varies can be done without a gradual transition.
- the combined image may be located on the side of a first face of the substrate and the revealing frame may be located on the side of a second face of the substrate, opposite to the first.
- the combined image and the revealing frame may be located on the side of a first face of the substrate.
- the security element may have on the side of a second face of the substrate, opposite to the first, a reflective surface for observing the coded images through the revelation frame.
- the combined image may be located between the revelation frame and the substrate.
- the reflecting surface is for example formed by a metallization of the second face of the substrate. This is for example a metal deposit of at least 200 ⁇ or a change in refractive index sufficient to cause reflection.
- Authentication and / or identification can be done by observation of the front or back side of the security element.
- the coded images can be observed in recto-side reflection, which coincides for example with the side of the revelation frame, but also with the back side.
- the security element is for example integrated in a security document, for example in windows, it may be advantageous to make both the front and back sides of the security element observable.
- the combined image and the revelation frame each advantageously comprise a metal layer.
- the layers can be made with the same metal or with different metals.
- the metal layer may have recesses or areas of zero thickness.
- the metal layer may be discontinuous.
- the metal layer may thus comprise a plurality of metallic patterns.
- the security element resulting from their superposition may have shiny metallic highlights. This effect is all the more surprising since the combined image or the revelation pattern observed alone has a matte homogeneous appearance without metallic reflection.
- the metal may be chosen for example from silver, aluminum, nickel, cobalt, tin, gold, copper, and from alloys of metals, such as brass or bronze.
- metal is also meant any dielectric material.
- the dielectric structures with mirror effect may consist of alternating layers of high and of low index, for example Hafnium dioxide and silica dioxide respectively, and may in particular be obtained by ion etching.
- the metal may be deposited by any deposit method known from the prior art.
- the metal may be deposited by chemical deposition or a vacuum deposition technique.
- the metal deposition may for example be carried out by cathodic sputtering on the substrate.
- the metal deposition can be carried out by any type of printing that can use metal inks, for example offset, intaglio, laser, gravure or screen printing.
- Deposition of the metal can be performed with a desired pattern using a mask directly on the substrate.
- the metal layer may alternatively be obtained with the desired pattern by partially demetallizing the previously metallized substrate at points or wefts having a suitable density.
- Demetallization can be carried out for example by etching or by removal of metallic particles made nonadherent, in particular by means of a laser.
- the metal layer may for example have a thickness greater than 150 ⁇ , especially between 200 and 1000 ⁇ .
- One of the combined image and the revelation screen may comprise a layer of a metal selected from silver, aluminum, nickel, tin, brass, among others, and the other may include a layer of a metal selected from copper, gold, bronze, among others.
- a metal selected from silver, aluminum, nickel, tin, brass, among others and the other may include a layer of a metal selected from copper, gold, bronze, among others.
- two different metals one carried by the combined image and the other by the revelation weft, it is possible to use two metals of different colors as described above, in particular such as aluminum and the copper.

- the document substrate especially at the level of the windows 31 and 32, may also have an opacity allowing the observation of the coded images on both sides of the security document, being for example at least partially transparent.
- the document 10 may also include a through window 31, as shown in Figure 13D, the security element 1 being located at least partially in this window. In this way, it would be possible to observe the coded images of both the front side and the back side of the security document 10.
- the security element in the form of a security thread can still be incorporated in a security document 10 which has an alternation of front and back side windows 31 and 32, as illustrated in FIG. 13C. It is thus possible to observe the coded images of both the front side and the back side of the security document 10 at the windows 31 and 32.
- FIGS. 15 and 17 illustrate variants of observation of security elements 1 according to the invention.
- the observation of the security element 1 can be done through the use of a bottom 30 on which the security element 1 is placed or which belongs to the security element.
- the face 2b of the security element 1 comprising the revealing frame 4 may be in contact with the bottom 30, as illustrated in FIG. 15.
- the face 2a of the security element 1 comprising the combined image I may be in contact with the bottom 30, as illustrated in FIG.
- the revelation screen 4 is silver in color
- the combined image I is copper-colored
- the background 30 is white in color.
- the user can thus observe a revealing frame 4 of silver color and a copper-colored spiral in contrast with the colors of the revelation frame and the background.
- the user can thus successively observe the coded images appearing as a mixture of silver color and copper color.
- the contrast effect obtained can also result from the observation in transvision of the security element 1 facing a light source 31, for example sunlight, as illustrated in FIG.
- FIG. 17 shows an alternative embodiment of a revelation screen 4 and a combined image I that can be used in a security element 1 according to the invention.
- this exemplary embodiment illustrates the possibility of producing a revelation frame 4 and a combined image I so that the coded images can be observable in the two main directions of inclination of the security element 1, especially in the sense of width and length.
- the revelation screen 4 can thus result from the combination of two frames 4a and 4b having bands extending along perpendicular axes, as can be seen in FIG. 17.
- the combined image I can result of the combined image combination Ia and Ib which respectively correspond to the combined images associated with the frames 4a and 4b.
- the animation effect obtained can thus be observed in at least two directions of inclination of the security element 1.
- FIG. 18 shows an exemplary security article 10 comprising a perforation 40 in which at least two sub-elements are placed, in particular in the form of foils or patches, 41 and 42 to form a security element 1 according to FIG. the invention.
- the sub-element 41 comprises for example a revelation frame 4 and the sub-element 42 comprises for example the corresponding combined image I.
- the security article 10 comprises a combined image I made in the form of impressions on the surface of the security article 10.
- a sub-element, in particular in the form of foil or patch, 43 is placed on the prints constituting the combined image I, the sub-element 43 having the corresponding revelation frame 4.
- the revelation frames 4 and / or the combined images I could be made differently, for example being incorporated or located above or below the sub-elements 41, 42 and 43.
- the security element 1 differs from that of FIG. 1 in that it comprises two non-opaque, for example perfectly transparent, substrate layers 2 and two combined images I and F. Both substrate layers here have the same thickness, for example 25 microns.
- the first combined image I is arranged facing the face 2b of the security element and represents for example a pattern such as a cloud.
- the second combined image F is disposed between the two substrate layers
- the period p of the revelation frame is in the example considered equal to the thickness of a substrate layer, that is to say to 25 microns.
- the nested images I 1 and F 1 forming respectively the first and the second combined image are in the example of FIG. 20 arranged in the same way so that during a change of observation angle from the face 2a of the security element, the pattern represented by the second combined image F will move twice as slowly as the pattern represented by the first combined image I since only half as many nested images F 1 as nested images I 1 will have been visualized by the eye.
- This example makes it possible to demonstrate the possibility with the invention of obtaining a movement effect between the patterns represented on the nested images.
- Such an effect, which can still be described as "effect of depth" is for example similar to that provided by the "differential scrolling" of the first video games.
- the example of FIG. 20 can be obtained by assembling, in particular by gluing, the different substrate layers 2.
- the example of FIG. 20 is obtained from a laser-marked monolayer substrate in which at least the combined image I is formed in the substrate by exposure to laser radiation.
- the combined image F and / or the revelation screen are in particular printed or labeled by laser irradiation.
- the use of the laser makes it possible to mark said laser-marked substrate at the desired depth, and also to mark said substrate at at least two depths. (Thicknesses) different, for example to form in a monolayer substrate at least two of the revelation frame and the combined images.
- the invention is not limited to the illustrated examples.
- the security element can be realized with other first, second or third level security, for example.
