Definitions

the invention relates to a security element for security papers, documents of value and the like, with a laser-markable transparent or translucent marking layer, in which by the action of laser radiation visually recognizable markings in the form of patterns, letters, numbers or images are introduced.
the invention also relates to a security paper and a data carrier with such markings and a production method for a corresponding security element, security paper or a corresponding data carrier.
ID cards such as credit cards or identity cards
ID cards have long been provided by laser engraving with an individual identification.
marking by laser engraving the optical properties of the card material in the form of a desired marking are irreversibly changed by suitable guidance of a laser beam.
an identity card with applied information is described, which has on a surface of different colored and stacked layer areas, which are at least partially interrupted by visually recognizable personalization data.
the invention has for its object to propose a security element of the type mentioned, the laser-generated Has high anti-counterfeiting markings.
the markings should in particular have a viewing angle-dependent visual appearance.
the markings of a generic security element each comprise a lamellar structure of a plurality of substantially parallel, extending in the depth of the marking layer lamellae, which are characterized by the parameters color, width, height, lateral orientation, angle of inclination and distance.
the marking layer is arranged according to a preferred variant of the invention on an opaque base layer, whose intrinsic color is at least partially recognizable when viewed parallel to the lamellae of a lamellar structure.
the marking layer is arranged on a transparent or translucent base layer, so that the security element is at least partially translucent when viewed parallel to the lamellae of a lamellar structure.
the security element can then be used, for example, over a transparent area of a data carrier, or it can, under certain viewing directions, open the view to an underlying data carrier.
the marking layer can also be arranged between the base layer and an effect color layer, since, as will be explained in more detail below, the identification does not have to start on the surface of the security element, but can also be introduced into a deeper region of the security element by suitable choice of the laser parameters. For this purpose, for example, the wavelength, intensity and focus of the laser radiation are adjusted so that the threshold for a visually detectable change in the laser-loaded material is not exceeded until the desired layer depth.
the lamellar structures of different markings differ at least in their lateral orientation in order to achieve a different visual appearance upon rotation of the security element.
the lamellar structures of various markings may differ at least in their inclination angle in order to achieve a different visual appearance with a tilting of the security element.
the lamellar structures of various markings may also differ in at least one of the parameters color, width, height and distance in order to produce areas with different visual appearance within the security element. These parameter differences can be combined with different tilt angles or different lateral orientations.
the lamellar structures of different markings can for example also be offset from each other.
the height of at least a portion of the lamellae is less than the layer thickness of the marking layer according to a preferred embodiment of the invention.
the height of the slats can be adjusted as desired by controlling the laser energy.
the fins may begin at the base layer and reach to a maximum height which is smaller than the layer thickness of the marking layer.
the lamellae start at a certain height above the base layer, so that additionally a parallax effect occurs during the movement of the security element.
This can be achieved for example by different laser sensitivities in different layer regions of the marking layer or by a partial presensitization of the material of the marking layer.
the latter approach even makes it possible to easily introduce parallax images in a homogeneous layer.
substantially unrecognizable, presensitized areas are produced in the marking layer by a first laser.
the presensitized areas may be formed in particular even in the form of lamellar structures.
visually recognizable markings are then produced in the overlap area within the presensitized areas.
the lamellae may be formed in the form of straight lines, curved lines, broken lines and / or in the form of lines of varying width.
color areas in particular gray areas, are arranged between the lamellae of at least one marking. These color areas change their color or gray value when turning and / or tilting the security element is not.
markings of the marking layer together with other markings of the security element provide overall information. The total information is then recognizable only from certain viewing angles.
marking layers instead of a single marking layer, it is also possible to provide a plurality of marking layers, each with a layer thickness of between approximately 50 ⁇ m and approximately 300 ⁇ m.
the marker layers may also be spaced such that indicia may be generated at different depths of the security element.
indicia may be generated at different depths of the security element.
a parallax effect likewise arises, since the identical markings precisely overlap one another only from a certain viewing direction, while the markings appear widened or doubled from other viewing directions.
the lamellae advantageously have a height of between about 50 ⁇ m and about 150 ⁇ m. Its width is limited downwards by the focus diameter of the laser beam and is preferably between about 20 microns and about 150 microns, more preferably between about 70 microns and about 120 microns.
the invention also includes a security paper for the production of security or value documents, such as banknotes, checks, identity cards, certificates or the like, as well as a data carrier, in particular a branded article, a value document or the like.
the security paper or the data carrier has a laser-markable transparent or translucent marking layer, into which visually recognizable markings in the form of patterns, letters, numbers or images are introduced by the action of laser radiation.
the markings each comprise a lamellar structure of a plurality of substantially parallel lamellae extending into the depth of the marking layer, which are characterized by the parameters color, width, height, lateral orientation, angle of inclination and distance:
the security paper or the data carrier can be either equipped with a security element of the type described above or even be provided with such markings. Also in the latter case, the markings are advantageously formed in the manner already described in more detail above.
the invention further includes a method for producing a security element, security paper or data carrier with a laser-markable transparent or translucent marking layer, in which markings in the form of patterns, letters, numbers or images are introduced into the marking layer by the action of laser radiation.
the markings are each formed with a lamellar structure of a plurality of substantially parallel, extending into the depth of the marking layer lamellae, which are characterized by the parameters color, width, height, lateral orientation, angle of inclination and distance.
An infrared laser in the wavelength range from 0.8 ⁇ m to 3 ⁇ m in particular a Nd: YAG laser, or a related laser, such as a Nd: glass laser, an Nd: YVO 4 -lase or the like, is preferably used for identification. used.
the markings with pulsed laser radiation for example, with a power between 3 W and 150 W, preferably between 3 W and 50 W, introduced.
the lamellar structures according to the invention can be made very fine and can be generated very precisely by the high accuracy of the beam guidance.
the freedom of the beam guidance allows a high variability of the producible markings, which give the designer a great deal of creative freedom.
the markings can also be retrofitted and deep-set selectively by already existing layers in a security element, security paper or a data carrier.
the material for the laser-markable marking layer and the laser radiation used for the marking are optimally matched to one another.
those skilled laser-markable plastics such. Polyethylene (PE), polycarbonate (PC), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyethylene naphthalate (PEN), polypropylene (PP), polyamide (PA).
the plastic may also be monoaxially or biaxially stretched. The stretching of the plastic leads inter alia to the fact that it receives polarizing properties that can be used as another security feature.
the tools required for exploiting these properties, such as polarization filters, are known to the person skilled in the art.
the marking layer and laser radiation very well absorbing additives such.
TiO 2 or infrared absorber to bring in the markers at low beam intensity can.
FIG. 1 schematically shows an identification card 10, which typically contains a portrait of the cardholder and other data not shown in the figure.
the identification card 10 is provided for authenticity assurance with a security element 12 according to the invention with a Venetian blind image, which shows a different visual appearance depending on the viewing direction of the viewer.
the security element 12 to a transparent marking layer 14, in which at least one visually recognizable label 16 is introduced in the form of patterns, letters, numbers or images by the action of laser radiation.
the marking 16 has a lamellar structure 18 of a multiplicity of lamellae 20 extending substantially parallel and extending into the depth of the marking layer 14, which is characterized in particular by the parameters color, width, height, lateral orientation, angle of inclination and spacing of the lamellae 20 ,
the slats 20 in the embodiment of Fig. 2 a width of about 100 microns, a distance of about 120 microns, an inclination angle of about 50 ° and a height of about 150 microns.
only one lamellar structure is provided in the security element, and the lamellae 20 of the lamellar structure 18 have a uniform lateral orientation, as for example in the plan view of FIG Fig. 3 recognizable.
the transparent marking layer 14 is arranged on an opaque base layer 22, the intrinsic color of which differs markedly from the color of the lamellae.
the base layer 22 may be formed by a white opaque card foil from which the lamellae 20 contrast in contrast to the laser-induced blackening of the marking layer 14.
the security element 12 is now viewed from a viewing direction 24 parallel to the lamellae 20, the white inherent color of the base layer 22 between the black lamellae 20 can be clearly seen. From this line of sight, the white and black areas alternate in rapid succession, giving the viewer the impression of a uniformly gray surface whose brightness depends on the selected ratio of slat width to slat spacing.
the inclined slats 20 obstruct the view of the base layer 22, as in the case of a venetian blind, so that the viewer only recognizes a uniformly black area.
the environment 28 of the marking 16 may be formed in a gray tone that corresponds to the gray tone of the marking 16 at a certain viewing angle, so that the marking 16 is not recognizable from this viewing angle.
the image information of the label 16 can be made to appear or disappear.
the security element 30 contains a marking layer 32 with a first lamellar structure 34 characterized by a first parameter set and a second lamellar structure 36 characterized by a second parameter set.
the first and second lamellar structures 34 and 36 differ in at least one of their characteristic parameters so as to produce a different visual appearance from different viewing directions.
the base layer 38 of the security element as in the embodiment of the Fig. 2 , opaque or transparent or translucent.
the security element 30 is partially transparent in viewing directions parallel to one of the lamellar structures 34, 36. This can for example be exploited for a transmitted light effect, or even only to make visible through the security element 30 an underlying disk.
At least the lateral orientation of the inclined blades 42 and 44 differs so that the visual appearance of the inscribed marking changes as the security element 40 rotates. For example, if the observer looks at the security element from the viewing direction 46, he looks in parallel to the inclined lamellae 42 and thus in partial areas onto the base layer arranged below the marking layer. The interior of the label "10" thus appears with a first brightness in a first Colour. This first image impression can be selected, in particular, by the color of the base layer, the color, the width and the spacing of the lamellae 42 as desired.
the inclined louvers 44 shade the base layer for the viewer from the viewing direction 46, so that the environment of the designation "10" appears with a second brightness in a second color, this second image impression being given essentially only by the color of the louvers 44 ,
the situation reverses.
the viewer now looks parallel to the fins 44 and thus partially on the base layer, while the fins 42 obstruct the view of the base layer.
the appearance of the security element 40 thus changes in rotation in a predetermined manner.
the security element 50 of Fig. 5 (b) contains two lamellar structures whose lamellae 52, 54 have the same lateral orientation, but include different angles of inclination with the surface normal.
the security element 50 thus represents a tilting image whose visual appearance changes when tilted about a tilt axis parallel to the slats.
the fins 52 can have an inclination angle of + 30 °
the fins 54 have an inclination angle of -40 ° to the surface normal.
the observer looks at the security element from the direction of observation 56, he is looking parallel to the lamellae 52 inclined towards him and thus in partial areas to the base layer below the marking layer.
the interior of the label "10" thus appears with a first brightness in a first color.
this first image impression can be reflected by the color of the base layer, the color, the width and the distance the fins 52 can be selected as desired.
the slats 54 inclined away from the viewer shade the base layer for the viewer from this viewing direction so that the environment of the marking "10" appears with a second brightness in a second color, wherein the second image impression essentially only results from the color of the slats 54 given is.
the situation is reversed, since the viewer is now looking parallel to the lamellae 54 and thus partially to the base layer, while the fins 52 obstruct the view of the base layer.
the appearance of the security element 50 thus changes in tilting in a predetermined manner.
Fig. 7 shows a security element 70 with different height slats.
the higher fins 72 require smaller tilt angles than the lower fins 74 in order to shade the base layer 76.
the different height of the slats can be adjusted by an appropriate control of the laser energy at will.
Fig. 7 also illustrates a further advantage of the blinds according to the invention.
the wavelength and intensity of the laser radiation can be selected and adapted to the properties of existing layers, such as a applied pressure layer 78, are tuned so that the lamellae, such as the lamellae 72 and 74, can be introduced through these layers into deeper layers of the security element, without removing the existing layers.
the markings according to the invention can therefore also be used for the subsequent personalization or individualization of security elements or data carriers.
infrared radiation of a pulsed Nd: YAG laser with a power between 3 W and 50 W can be used.
the blackening of the marking layer may also be effected through an effect layer, as in Fig. 8 illustrated.
the marking layer 82 of the security element 80 is disposed between a base layer 86 and an effect color layer 88.
the effect ink layer 88 may include, for example, optically variable interference pigments, thermal dyes, or the like.
the wavelength, intensity and focus of the laser radiation are selected so that the marking layer 82 is provided with lamellae 84 without destroying the effect color layer 88.
both the viewing angle-dependent marking and the optically variable effect of the effect color layer are present.
the laser marking 92 in other subregions 94 can also be designed such that the effect color layer 88 is destroyed locally, so that there is no longer any optically variable effect.
a parallax image is introduced into the marking layer 102, in which the Blackening 104 are located at a certain height h above the base layer 106.
a parallax effect occurs due to the movement of the blackening 104 against the background of the spaced-apart base layer 106.
This particular identification is produced according to the invention in that the material of the marking layer 102 is presensitized by a first laser irradiation from a specific irradiation direction.
the presensitized areas used in the Fig. 9 are denoted by the reference numeral 108, are themselves visually unrecognizable, but the threshold for generating a visible laser mark is reduced in them.
the presensitized regions advantageously include a tilt angle of about 30 ° to about 50 ° with the surface normal.
the material of the marking layer 102 is now blackened in the overlap areas with the presensitized areas 108.
a suitably set laser intensity can be ensured that the material is not visually changed in the non-presensitized areas by the second laser.
the first and second lasering can take place simultaneously, so that a higher laser intensity prevails in the overlap area of the laser beams than outside.
the laser intensities are chosen so that they are individually not enough to blacken the material, the higher laser intensity However, in the overlap area above the Schwärzungsschwelle.
the second laser can be done in time but also after the first laser.
the first laser reduces the blackening threshold of the material in the presensitized areas, which change itself is not visually discernible.
the laser intensity is now chosen to be above the blackening threshold of the presensitized material but below the blackening threshold of the unmodified material. This also achieves the desired effect.
the lamellae of the markings can be formed in all described embodiments straight and with a constant width.
Fig. 10 (a) shows a plan view of such a lamellar structure with straight blades 110 and constant width b.
the achievable width of the slats is given down by the focus diameter of the laser used for marking.
the focus diameter is typically between 20 ⁇ m and 150 ⁇ m, preferably between 70 ⁇ m and 120 ⁇ m, so that corresponding fin widths b result.
lamellar structures can be used which form curved lines in the plane of the marking layer.
Fig. 10 (b) and Fig. 10 (c) schematically show embodiments of lamellar structures with lamellae 112 , 114 with a changing width. When viewed parallel to the slats thereby changes the visible portion of the base layer, so that the brightness impression varies along the slats. It is understood that this change in real embodiments, other than in the schematic representation of Fig. 10 (b) and Fig. 10 (c) , compared to the spacing of adjacent lamellae, typically takes place on a much larger length scale.
the shutter images according to the invention can also represent a halftone image under certain viewing angles.
the different shades of gray of a halftone image can be generated by lamellar structures 116, 118, 120 having parallel lamellae with different pitches between the louvers, as in the left half of FIG Fig. 10 (d) illustrated.
different shades of gray can be produced by lamellae of different widths in the lamellar structures 122, 124, as shown on the right in FIG Fig. 10 (d) shown.
Any predetermined halftone image can easily be represented with such lamellar structures, for example by assigning a small surface area of the security element to each halftone pixel, and providing this area area with a lamellar structure corresponding to the brightness of the halftone pixel.
the halftone image is recognizable from other viewing directions, from which the slats obstruct the view of the base layer, shows only a uniformly colored surface.
