DETAILED DESCRIPTION OF THE INVENTION

1 shows a security document in a cross-sectional view. The security document consists of a substrate layer 11 , which is preferably matte, with a glossy layer 12th made of a shiny material. The substrate layer 11 can consist of different materials, e.g. B. made of paper, plastic (such as polycarbonate (PC) or polyvinyl chloride (PVC)), paper mixed with plastic fibers or paper mixed with plastic (ie a hybrid substrate).

The shiny layer 12th can be made of different materials. You can z. B. be made of a metallic foil. It can also be in the form of a coating, such as e.g. B. a metal coating, a metallic paint, an iridescent coating, a glossy paint or an optically variable color. The shiny layer 12th can be applied to the substrate layer using various techniques such as offset printing, typo-offset printing, typographic printing, screen printing, flexographic printing, hot stamping or cold stamping 11 be applied.

The shiny layer 12th is glossy when illuminated with light (e.g. visible light) while the substrate layer 11 when illuminated with the same light has a luster that differs from the luster of the shiny layer 12th differs. Especially when the substrate layer 11 is matt, shows the substrate layer 11 no shine.

As in 2 Shown in enlargement, includes the glossy layer 12th at least three zones 21 , 22nd , 23 each made up of strips 31 , 32 , 33 that exist within the material of the shiny layer 12th are trained. The zones include a central zone 22nd with a multitude of parallel stripes 32 that are formed in this zone. The middle zone 22nd is located between two side zones 21 , 23 , with each side zone 21 , 23 a multitude of parallel stripes 31 , 33 has that in the respective side zone 21 , 23 are trained.

The Stripes 31 , 32 , 33 each zone 21 , 22nd , 23 can be shaped by various techniques such as: B. Steel engraving (without color) or dry embossing.

An important aspect of all the embodiments presented here is that at least one strip 32 the central zone 22nd in relation to its closest strip 21 a side zone 31 as well as in relation to its closest stripe 23 another side zone 33 is inclined at an angle other than 180 °.

Preferably there is at least one strip 32 the central zone 22nd across from its closest strip 31 a side zone 31 and across from its nearest strip 33 another side zone 33 inclined at an obtuse angle in a range of 90 ° to 178 °, these strips being 31 , 33 of the side zones 21 , 23 on the same side of the line 40 are formed, which is an extension of the strip 32 the central zone 22nd forms. The stripes that form the obtuse angles, namely stripes 31 and stripes 32 or stripes 32 and stripes 33 , can lie against one another or they can be spaced from one another. In the latter case, the angle can be measured at an intersection of the lines which form an extension of these two spaced apart strips.

In 2 are the stripe 32 the central zone 22nd and its two closest stripes 31 , 33 of the side zones 21 , 23 indicated schematically by bold lines, while the side zones 21 , 23 as well as the central zone 22nd are indicated by dashed lines to improve the clarity of the drawing.

Every stripe 31 , 32 , 33 in the area of the individual zone 21 , 22nd , 23 has a width of no more than 100 microns. For example, any stripe can 31 , 32 , 33 have a width in the range from 10 to 100 micrometers, preferably 50 micrometers. In addition, a distance exceeds D. (in 1 shown) between two adjacent strips in the area of a single zone is not 100 micrometers.

The Stripes 31 , 32 , 33 of at least one zone 21 , 22nd , 23 can be straight or curved or straight and curved. For example, have the stripes 31 , 32 , 33 a wavy shape.

The features discussed above, including the dimensions of the strips, their mutual arrangement and preferably also an obstacle angle, are conveyed to the viewer 50 a visual impression of the movement of the stripes between the central zone 22nd and the side zones 21 , 23 . This movement is in 3 shown schematically and gives the security element a technical effect and benefit.

Every stripe 31 , 32 , 33 may due to its training in the shiny layer 12th reflecting incident light, taking the dimensions of the strip 31 , 32 , 33 as well as their mutual arrangement cause the effect that the viewer 50 if the security document is illuminated with light, only the strips 31 , 32 , 33 or just the parts of the strips 31 , 32 , 33 can see which is substantially perpendicular to the direction of incident light 51 are trained. For example, as in 3A shown the stripes 31 the first side zone 21 that are perpendicular to the direction of incident light 51 stand for the viewer 50 visible, as schematically marked with a bold line. The Stripes 32 the central zone 22nd and the stripes 33 the second side zone 23 are on the other hand for the viewer 50 not visible.

When the direction of incident light changes 51 turn are for the viewer 50 the Stripes 32 the central zone 22nd ( 3B) or the stripes 33 the second side zone 23 ( 3C ) visible. The viewer 50 can only use the stripes 32 or. 33 see which at the moment is perpendicular to the direction of incident light 51 stand.

When changing the direction of incident light 51 continuously changes, e.g. B. when the viewer 50 the angle of inclination of the security document in relation to the direction of the incident light 51 changes, the visibility of the stripes changes 31 , 32 , 33 corresponding. This creates the impression of a movement of the strips on the surface of the security document.

The shiny layer 12th can have more than three zones 21 , 22nd , 23 include the strip. The shiny layer 12th can e.g. B. four zones, five zones, six zones, seven zones or more than seven zones of the strips 21 , 22nd , 23 include.

In addition, in one embodiment, the central zone 22nd and the side zones 21 , 23 the stripe 31 , 32 , 33 on the substrate layer 11 be arranged so that the zones are spaced apart. For example, the central zone 22nd either from one side zone or from both side zones 21 , 23 be spaced. The zones can e.g. B. be spaced by a solid line. In another embodiment, the central zone 22nd to the first and second side zones 21 , 23 adjoin, or the central zone 22nd can be attached to one of the side zones, either the first or the second 21 , 23 , adjoin.

The zones 21 , 22nd , 23 with the stripes 31 , 32 , 33 can be of different shapes or designs, e.g. B. The zones can take the form of parallel bands ( 4th ), concentric rings ( 5 , 7A) , graphic characters, letters, numbers and / or repetitive patterns such as wallpaper patterns ( 7B) to have. 7A shows, enlarged, a repeating unit of the in 7B shown pattern. The security element in one embodiment comprises a plurality of the zones 21 , 22nd , 23 the stripe 31 , 32 , 33 . For example, the security element of the security document, as in 4th shown comprise seven striped zones, or the security element can comprise four striped zones, as in FIG 5 shown so that the security element the benefit and the having a technical effect like the embodiment with three zones of the strip.

In the in 5 embodiment shown has the central zone 22nd the shape of a ring, while the side zones 21 , 23 Form adjacent, concentric rings: one side zone forms an inner ring and the other side zone forms an outer ring. Depending on the direction of the incident light 51 (shown schematically by arrows) the viewer can 50 recognize the zones of the stripes in which the stripes are perpendicular to the direction of the incident light 51 are formed as schematically by a darker color in 4th and 5 marked.

The shiny layer 12th with the formed zones 21 , 22nd , 23 the strip can be the substrate layer 11 partially or completely cover. In the latter case, the glossy layer can 12th have a surface with different shapes, e.g. B. the shape of a banknote denomination - as in 8C shown - or the shape of an inscription or the shape of various graphic elements, such as. B. a full strip formed over the entire width of the security document 12th : 8B , near the transparent graphic pattern, e.g. B. of the pattern " 20th ".

In another embodiment, the security document can have flat areas 60 the shiny layer 12th , ie without shaped stripes, as in FIG 6th shown schematically. The flat areas 60 do not have the optical effect described above.

In a further embodiment, the glossy layer 12th be provided with a space, e.g. B. in the form of a graphic character, a character made of letters or a numeric character. In addition to the blank space, the security document can also include various areas, such as e.g. B. Grid areas 62 (as in 10A shown) or relief areas 63 (as in 10B shown) or another area.

In a further embodiment, the glossy layer 12th can be applied to the transparent film, and together with this film the glossy layer 12th on the substrate layer 11 applied to zones 21 , 22nd , 23 the stripe 31 , 32 , 33 to form as in 8A and 8B shown.

Furthermore, the glossy layer 12th the zones 21 , 22nd , 23 which have stripes formed on the entire surface - as in the 4th , 5 , 6th , 7A , 7B shown, or the shiny layer 12th the surface can be in the form of a numerical symbol, eg " 20th “, As well as the flat areas 60 - without formed stripes, and the areas of the zones 21 , 22nd , 23 of the formed stripes - as in 11A shown. The security document can also be in the substrate layer 11 stripes formed within the areas not covered with the shiny material. In such an embodiment, the viewer can 50 only those in the shiny layer 12th see formed stripes. 11B shows the same embodiment as in FIG 11A , with those in the shiny layer 12th formed stripes that are visible to the viewer 50 are visible, are marked.

12A shows a further embodiment in which the security document has a glossy layer 12th the surface is provided, which has the number pattern of " 20th “Forms, with the shiny layer 12th Zones of the stripes formed on its entire surface. The strips have the visual effect described above. In addition, the security document can comprise the strips in areas of the substrate layer 11 that are not formed with the glossy layer 12th are covered so that the strips do not have the visual movement effect described above. The strips that are only in the substrate layer 11 are designed are for the viewer 50 not visible, as in 12B shown.

In another embodiment described in 9 is shown, the security document can in addition to the glossy layer 12th comprise further layers, for example a carrier layer 13th that can be made of paper, for example, that has a blank in the form of a window 131 has on which the glossy layer 12th with zones 21 , 21 , 23 made of shaped strips 31 , 32 , 33 can be applied.

The construction of the zones 21 , 22nd , 23 of shaped strips 31 , 32 , 33 represents a security element of the security document. The technical effect and thus the benefit of the security element is as follows. The viewer can only see certain stripes, while the other stripes remain invisible to the viewer, depending on the angle of the incident light 51 . This effect can only be seen if the security element consists of at least three zones 21 , 22nd , 23 the stripe 31 , 32 , 33 - The arrangement described above - consists. Accordingly, the viewer has 50 with a flowing change of the angle of view the impression of a movement of the stripes between the respective zones. The effect achieved in this way is similar to the effect of kinematic holograms, but the security document is created by embossing the stripes in the glossy layer 12th , that is, in a simpler way than with the hologram.

In addition, the glossy layer can 12th also include flat areas with no shaped stripes in which the reflection of light, as with shaped stripes, is not observed.

While the invention has been described with respect to a limited number of embodiments, it will be understood that many variations, modifications, and other uses of the invention can be made. Therefore, the claimed invention as set out in the following claims is not limited to the embodiments described herein.
