Definitions
- the present invention relates to secure documents and security elements used to secure documents.
- Banknotes and other secure documents including checks, money orders, identity cards, credit cards or guarantee cards, for example formed from paper and incorporating security threads or including security films, that is, more or less wide bands, have been in circulation for a number of years and are now widely used in many countries.
- the security threads are in these documents in some cases exposed to sight, in reflected light, in predefined regions present on at least one side of the document, these regions being commonly called “windows”.
- Security threads make imitation of secure documents more difficult. They help authenticate documents, usually by giving them a different look in transmitted light and reflected light.
- Safety son are conventionally made with zones producing patterns in transmitted light, thanks to the presence of a metal layer provided with recesses allowing light to pass when the document is observed in transmitted light.
- EP 1 674 286 A1 relates to a security element reproducing a subject with the aid of an image formed of raster points. It is indicated that the image may be formed of several layers having different optical densities.
- WO 99/04983 discloses a security element comprising a semi-reflective layer covering a magnetic layer.
- WO 2007/020370 A2 discloses a security thread having macroscopic patterns each formed of microscopic patterns.
- EP 0 659 587 A1, EP 0 319 157 A2, WO 2007/141459 A2 and WO 2013/160880 A2 disclose other security elements.
- EP 0 998 396 B2 discloses a security element having two metal layers having different optical densities, with for example a more opaque layer having a transmission factor of at most 30% and a less opaque layer having a transmission factor of at least 50%.
- the two layers can be in the same metal or in different metals.
- the security element comprises a magnetic layer that may include recesses in the form of characters for example.
- the magnetic layer is covered by a semi-transparent layer, in the form of a frame.
- the semi-transparent layer thus hides the magnetic layer.
- the security element comprises a support which carries on its opposite faces two identical layers each in the form of a regular frame. A non-perforated layer is also present on one of the faces between the support and the semi-transparent layer.
- EP 1 503 903 B1 discloses a security element comprising a support coated on one side with a first perforated layer, of a first metal such as aluminum, covering a second equally open layer, with a second metal such as copper.
- the thickness of the metal of the second layer is sufficiently low for this layer to be semi-transparent.
- the first and second layers have first apertures that coincide and the first layer has a second aperture that opens onto a solid portion of the second layer.
- the observer perceives the difference in color of the two metals, at the first and second openings of the first layer.

- the second layer is further semi-reflective.
- semi-reflective is meant a reflective layer, in particular with specular reflection, when observed in reflected light at a first angle of observation or illumination, and transparent when observed in reflected light respectively at a second angle d observation or illumination.
- the second semi-transparent layer may be opaque in appearance when viewed in reflected light, regardless of the angle of observation or illumination.
- the second layer makes it possible, if desired, to form a background of a color different from that of the material of the first layer, in reflected light, without unduly hindering the observation of the halftone pattern in half. tone in transmitted light.
- the first material is metallic, better is a metal.
- the second material is also.
- metals having different colors, such as copper and aluminum, or their alloys are chosen.
- the second layer advantageously comprises a semitransparent frame, to which it owes its semi-transparent character.
- the thickness of the metal of the lines or weft points may be sufficiently high so that the layer is locally opaque where the metal is present.
- the use of a frame provides additional possibilities for making patterns.
- the points or raster lines may be formed of elementary patterns, which provides an additional degree of protection.
- the second layer may comprise one or more macro-recesses, in particular in the form of alphanumeric characters, or an opening presenting the same outline as the halftone pattern of the first layer.

It is thus possible to obtain with the naked eye and for example at a distance of 10 cm, a similar aspect, particularly homogeneous, to a frame consisting of parallel lines.
- the frame may be interrupted in places to define at least one pattern within the layer of the second material, in particular the second metal, in particular a microscopic pattern, preferably an alphanumeric pattern.
- the layer of the first material may define a first alphanumeric pattern, positive or negative.
- the layer of the second material in particular the second metal, may define a second alphanumeric pattern, positive or negative.
- the second pattern may convey the same information as the first pattern, for example representing the same number, or the same word, or having the same meaning.
- At least one of the layers of the first and second materials, including first and second metals, may comprise one or more patterns in the form of a set of points or symbols.
- the pattern (s) present in the layer of the first material, in particular the first metal may be arranged in a manner marked with respect to the pattern (es) present in the layer of the second material, in particular the second metal, that is, the relative positions of the patterns of the two layers can be constant over the entire length of the element during its manufacture.
- the pattern or patterns formed within the layer of the first material, in particular the first metal may be visually independent of the pattern or patterns formed within the layer of the second material, in particular the second metal, that is to say that the patterns of each of the layers do not have to complement each other to take their full meaning in the eyes of the observer, in transmitted and / or reflected light.
- At least one pattern of the first layer and at least one pattern of the second layer complement each other in transmitted and / or reflected light.

- the screen points 32 have for example a polygonal shape, and the frame is amplitude modulated, that is to say that the pitch with which the screen points are arranged is regular, but the size of the points varies.
- the frame may be frequency modulated.
- Weft points can have very different shapes.
- the pattern 31 may also include zones 33 which appear in solid lines, for example the nose or the eyes, as illustrated.
- the security element 20 is made as illustrated with an alternation of alphanumeric patterns 30 and patterns 31 semitone in the longitudinal direction.
- the layer 26 of the second metal comprises, in the example in question, fine fields 34, which are arranged with a regular spacing and which are interrupted to form patterns 35. Preferably these patterns are repeated, and in this case represent the number 100.
- the size of a pattern 35 is preferably smaller than that of the pattern 30.
- the pattern of the lines 34 may appear as homogeneous to the naked eye if the lines 34 are sufficiently thin and close together.
- the width d of the raster lines 34 is between 20 and 25 ⁇ , with for example a spacing t between two adjacent frames 34 between 40 and 60 ⁇ .
- lines 34 with a width of 20 ⁇ , and a distance value t between them of 50 ⁇ .
- the lines 34 may be oriented obliquely with respect to the longitudinal axis of the support 22, or alternatively otherwise.
- the lines 34 may be rectilinear, as illustrated. In a variant, these lines 34 are curved, in particular corrugated.
- the number of lines 34 per inch (lpi) is greater than or equal to 800, preferably to 2000, so as to prevent any attempt to reproduce these lines by means of a conventional printer whose resolution is lower.
- the patterns are preferably microscopic, observable with magnification.
- the height of the figures of the patterns 35 is for example 100 ⁇ .
- the patterns are written upside down on the back side so as to appear at the front side.
- the patterns 35 may appear within the openings of the patterns 30 and 31 formed in the layer 24, in reflected light.
- the layer 24 may appear in reflected light through the patterns 35, where the patterns 35 are superimposed on the metallization surface of the layer 24, if the security element 20 is observable in reflected light on the side of the back.
- the observer can see through the support 32 of the security element including transmitted light.
- the opacity of the layer 24 is such that when the security element 20 is observed in reflected light on the side of the front face, the patterns formed in the layer 26 are not visible. other than at the level of the openings of the patterns 30 and 31 of the layer 24.
- the layer 26 of the second metal may be perceived as being substantially uniform in color by the observer, in reflected light, where it is superimposed on the solids of the layer 24. This gives the security element elsewhere than at the level of the patterns 35, on the side of the reverse side, a specific color related to the superposition of the weft lines 34 and the layer 24 and the visibility of the layer 24 between the lines 34.
- the apparent hue of the layer 26 in the raster region can be modified between the pure color of the second metal and that of the first metal.
- the color of the layer 26 appears different at the openings of the patterns 30 and 31, due to the absence at the level of the first metal of the layer 24.
- the surface state of the layers 24 and 26 is such that they produce a specular metal reflection on their surface.
- the layer 24 of the first metal reproduces the same patterns 30 and 31 as in the example of Figure 3.
- the layer 26 of the second metal which is visible on the back, has lines of parallel wefts 34 as in the example described above.
- these weft lines 34 define patterns 40 which are identical in size to those of the patterns 30.
- FIG. 12 illustrates the possibility for layers 24 and 26 of the first and second metals not to be completely superimposed.
- the layers 24 and 26 are superimposed only in a region 50, for example central, of the security element.
- the layers 24 and 26 are not located on the same side of the support 22 as in Figure 12, but on opposite sides.
- the first layer 24 comprises a halftone halftone pattern superimposed with an insulated pattern 70, of the same outline, of the second layer.
- the metal of the weft of the second layer 26 is seen in the openings of the halftone halftone pattern, the details of which it changes in reflected light. Thus, this pattern becomes visible in reflected light with a reflective background of the color of the second metal.
- FIG. 17 shows a security element 20 whose first layer 24 has first apertures 128a for making reflected in a reflected light a first type of pattern, in this case a face, and second apertures 128b of alphanumeric type, in this case a number corresponding to the face value of the note.
- the reasons for the openings 128b are advantageously alternately arranged at the place and upside down, as one moves along the security element, as illustrated. It is the same reasons for a journeys 128a. This allows to have both the front and back of the element 20 observable patterns at the place in reflected light.
- the layer 24 is for example a first metal such as aluminum.
- the pattern formed within the openings 128a may be a semitone halftone pattern, so as to reproduce a shading effect.
- the element 20 also comprises a layer 26 of a second metal different from the first, for example copper or a copper alloy.
- This second layer 26 is semi-transparent, for example due to the thickness of the metal.
- the second layer 26 is visible in reflected light on the one hand within the openings 128b, where it forms patterns 140 reproducing the meaning of those formed by the openings 128b, in this case the same numbers.
- An interval 141 can exist between the layers 24 and 26 within the openings
- the second layer 26 forms patterns 142 which complete the patterns formed by the first layer 24.
- the first layer 24 forms a pattern 144 in the form of a head in the openings 128a and the second layer forms the patterns 142 in the form of a cap covering this head.
- an interval 143 exists within each aperture 128a between the pattern 142 and at least a portion of the edge of this aperture 128a.
- the patterns 142 and 144 are not superimposed but complement each other, and together occupy the entire surface defined by the outline of the aperture 128a.
- the patterns 142 and 144 are formed by the first layer 24, and the second layer 26 is a semitransparent grid disposed in the zone of the patterns 142 and absent from the zone of the patterns 144, so as to constitute a bottom for motifs 142.
- the second layer 26 is semi-transparent and the patterns 142 and 144 form the subject, which then appears in a monochrome representation.
- the security element and / or the secure document may have one or more other conventional security elements, which may be first, second or third level.
- the security element can thus have at least one hologram or a network of microlenses, and one or more luminescent layers, in particular fluorescent under UV or IR.
- the microlens array may provide an enlarged microparticle image of layer 24 or 26, as appropriate.
