Definitions
- the invention relates to security elements with machine-readable features and color effects that improved counterfeiting and Imitation security.
- Security elements are used in many areas around the To ensure counterfeit security of sensitive goods. So be for example, in data carriers, in particular value documents, such as ID cards, banknotes, packaging materials for sensitive goods, such as pharmaceuticals, cosmetics, electronic components, labels, seals and For example, in the textile industry, such security features used.
- the object of the invention was to provide a security element that machine-readable features, such as magnetic features, which are not visible to the naked eye and which additionally have a defined Has color effect.
- the invention therefore safety elements with machine-readable features and color effects, characterized the security element is a preferably coded machine-readable one Feature characterized by a white, colored or luminescent layer is covered by effect pigments.
- Another object of the invention are film materials with machine-readable features and color effects, characterized that the film material is a preferably coded machine-readable Feature characterized by a white, colored or luminescent layer is covered by effect pigments.
- the features are applied to a flexible carrier substrate, wherein the the machine-readable feature layer on one or both Side of the carrier substrate may be applied.
- Carrier substrates are, for example, carrier films, preferably flexible transparent plastic films, for example of PI, PP, MOPP, PE, PPS, PEEK, PEK, PEI, PAEK, LCP, PEN, PBT, PET, PA, PC, COC, POM, ABS, PVC in question.
- the carrier films preferably have a thickness of 5 to 700 .mu.m, preferably 5 to 200 .mu.m, particularly preferably 5 to 50 .mu.m.
- metal foils for example Al, Cu, Sn, Ni, Fe or stainless steel foils with a thickness of 5-200 ⁇ m, preferably 10 to 80 microns, more preferably 20 to 50 microns serve.
- the Films can also be surface treated, coated or laminated for example, with plastics or painted.
- carrier substrates also paper or composites with paper, for example, composites with plastics with a grammage 20-500 g / m 2, preferably 40-200 g / m 2. be used.
- woven or nonwovens such as continuous fiber webs, staple fiber webs and the like, which may optionally be needled and / or calendered, can be used as the carrier substrates.
- fabrics or webs of plastics such as PP, PET, PA, PPS and the like, but it can also be woven or nonwovens of natural, optionally treated fibers, such as Viskosefasem be used.
- the nonwovens or fabrics used have a weight per unit area of about 20 g / m 2 to 500 g / m 2 . If necessary, the nonwovens or fabrics must be surface-treated.
- a full-surface or partial functional layer applied with a machine-readable feature.
- a machine-readable feature Preferably that has machine-readable feature magnetic properties and can also preferably encoded, for example in the form of a barcode.
- a functional layer consists of a printing ink with magnetic pigments or effect pigments with magnetic properties, For example, pearlescent pigments that are coated with metals or oxides. Pearlescent pigments with magnetic properties are for example Colorcrypt® from Merck.
- a magnetic pigment based on oxidic pigments such as Fe 2 O 3 or Fe 3 O 4 , metal pigments such as iron, nickel, cobalt or chromium and / or their alloys, for example: Cr-Ni steel (stainless steel), barium - or cobalt-ferrites or similar. These pigments can be hard or soft magnetic.
- Such a functional layer appears dark at the surface.
- this functional layer is overprinted on one or both sides with a layer of a printing ink having white, colored or luminescent pearlescent pigments.
- the first functional magnetic layer is covered on the one hand, on the other hand, depending on the pearlescent pigment used color effects. It is also possible by appropriate combination of several layers to achieve under or over or side by side defined, distinctive color effects.
- the printing is preferably carried out by means of a laser-coated cylinder or a printing plate, preferably in the gravure printing method, wherein the printing tool (cylinder or printing plate) is designed so that the coded magnetic layer optionally simultaneously with the characters to be imaged, patterns, letters, geometric figures, lines, Guilloche and the like can be printed.
- a cylinder blank which is suitable for gravure printing, with at least one 80 micron thick copper layer, for example, in a known galvanic Provided method, depending on the material of the blank, for example Aluminum, iron, etc., if appropriate beforehand an adhesion promoter layer, for example, can be applied from nickel.
- the thickness of the Copper layer is at least 80 ⁇ m, usually 100-1500 ⁇ m, preferably 250-500 ⁇ m.
- the cylinder blank is turned off to the exact extent and then ground to the appropriate roughness.
- the Roughness value Ra 0.03-2.0 particularly preferably 0.05-1.5, in particular 0.06 to 1.2.
- an engraving machine for example a Engraving machine manufacturer Hell or Ohio on the side of a passport in defined size, for example 5x5mm, engraved 0.2 mm thick.
- the cylinder thus prepared is treated with a commercially available photoresist, for example, LD 100 from OHKA Kogyo Ltd., coated.
- the thickness of this Coating is about 3 - 5 microns.

Auf das Trägersubstrat wird eine vollflächige oder partielle funktionelle Schicht mit einem maschinenlesbaren Merkmal aufgebracht. Vorzugsweise hat das maschinenlesbare Merkmal magnetische Eigenschaften und kann auch vorzugsweise codiert sein, beispielsweise in Form eines Barcodes. Vorzugsweise besteht eine derartige funktionelle Schicht aus einer Druckfarbe mit Magnetpigmenten oder Effektpigmenten mit magnetischen Eigenschaften, beispielsweise Perlglanzpigmenten, die mit Metallen oder Oxiden belegt sind.

oxidischen Pigmenten wie beispielsweise Fe2O3 oder Fe3O4, Metallpigmenten
wie Eisen, Nickel, Cobalt oder Chrom und/oder deren Legierungen, z.B.: Cr-Ni-Stahl
(Edelstahl), Barium- bzw. Cobalt-Ferrite oder ähnliche.
Diese Pigmente können hart- oder weichmagnetisch sein.Also particularly suitable is a magnetic pigment based on oxidic pigments such as Fe 2 O 3 or Fe 3 O 4 , metal pigments such as iron, nickel, cobalt or chromium and / or their alloys, for example: Cr-Ni steel (stainless steel), barium - or cobalt-ferrites or similar.
These pigments can be hard or soft magnetic.
Eine derartige funktionelle Schicht erscheint an der Oberfläche dunkel.Such a functional layer appears dark at the surface.
Daher wird in einem weiteren Schritt, vorzugsweise inline, diese funktionelle
Schicht ein- oder beidseitig mit einer Schicht aus einer Druckfarbe mit weißen,
färbigen oder lumineszierenden Perlglanzpigmenten überdruckt.
Dadurch wird die erste funktionelle magnetische Schicht einerseits abgedeckt
andererseits entstehen in Abhängigkeit vom verwendeten Perlglanzpigment
Farbeffekte.
Es ist auch möglich durch entsprechende Kombination mehrerer Schichten
unter- oder über- oder nebeneinander definierte, unverwechselbare Farbeffekte
zu erzielen.Therefore, in a further step, preferably inline, this functional layer is overprinted on one or both sides with a layer of a printing ink having white, colored or luminescent pearlescent pigments.
As a result, the first functional magnetic layer is covered on the one hand, on the other hand, depending on the pearlescent pigment used color effects.
It is also possible by appropriate combination of several layers to achieve under or over or side by side defined, distinctive color effects.
Ferner ist es möglich die Schicht mit magnetischen Eigenschaften bereits in situ
codiert aufzubringen.
Dabei erfolgt das Bedrucken vorzugsweise mit Hilfe eines laserbelichteten
Zylinders oder einer Druckplatte vorzugsweise im Tiefdruckverfahren, wobei
das Druckwerkzeug (Zylinder oder Druckplatte) so ausgestaltet ist, dass die
codierte magnetische Schicht gegebenenfalls gleichzeitig mit den
abzubildenden Zeichen, Mustern, Buchstaben, geometrischen Figuren, Linien,
Guillochen und dergleichen gedruckt werden kann.Furthermore, it is possible to apply the layer with magnetic properties already encoded in situ.
The printing is preferably carried out by means of a laser-coated cylinder or a printing plate, preferably in the gravure printing method, wherein the printing tool (cylinder or printing plate) is designed so that the coded magnetic layer optionally simultaneously with the characters to be imaged, patterns, letters, geometric figures, lines, Guilloche and the like can be printed.
Nach den derzeit bekannten Verfahren zur Herstellung von laserbelichteten Druckwerkzeugen (Scheppersverfahren, Thinkverfahren) ist die Herstellung von flächenvariablen, aber nicht tiefenvariablen Strukturen auf dem Druckwerkzeug möglich. According to currently known methods for the production of laser-exposed Printing tools (Scheppersverfahren, Thinkverfahren) is the production of surface variables, but not depth-variable structures on the printing tool possible.
Nachfolgend wird das erfindungsgemäße Verfahren zur Herstellung eines sowohl flächen- als auch tiefenvariablen Druckwerkzeugs am Beispiel eines Druckzylinders beschrieben.Hereinafter, the inventive method for producing a both area- and depth-variable printing tool on the example of a Printing cylinder described.
Ein Zylinderrohling, der für den Tiefdruck geeignet ist, wird mit einer mindestens 80 µm dicken Kupferschicht, beispielsweise in einem bekannten galvanischen Verfahren versehen, wobei je nach Material des Rohlings, beispielsweise Aluminium, Eisen usw. gegebenenfalls vorher eine Haftvermittlerschicht, beispielsweise aus Nickel aufgebracht werden kann. Die Dicke der Kupferschicht beträgt mindestens 80 µm, üblicherweise 100 - 1500 µm, bevorzugt 250 - 500 µm.A cylinder blank, which is suitable for gravure printing, with at least one 80 micron thick copper layer, for example, in a known galvanic Provided method, depending on the material of the blank, for example Aluminum, iron, etc., if appropriate beforehand an adhesion promoter layer, for example, can be applied from nickel. The thickness of the Copper layer is at least 80 μm, usually 100-1500 μm, preferably 250-500 μm.
Der Zylinderrohling wird auf genaues Umfangmaß abgedreht und anschließend auf die entsprechende Rauhigkeit geschliffen. Vorzugsweise beträgt der Rauhigkeitswert Ra 0,03 - 2,0, besonders bevorzugt 0,05 - 1,5, insbesondere 0,06-1,2.The cylinder blank is turned off to the exact extent and then ground to the appropriate roughness. Preferably, the Roughness value Ra 0.03-2.0, particularly preferably 0.05-1.5, in particular 0.06 to 1.2.
Anschließend wird auf einer Gravurmaschine, beispielsweise einer Gravurmaschine der Hersteller Hell oder Ohio an der Seite ein Passkreuz in definierter Größe, beispielsweise 5x5mm, Stärke 0,2 mm aufgraviert.Subsequently, on an engraving machine, for example a Engraving machine manufacturer Hell or Ohio on the side of a passport in defined size, for example 5x5mm, engraved 0.2 mm thick.
Der so vorbereitete Zylinder wird mit einem handelsüblichen Photoresist, beispielsweise LD 100 der Fa. OHKA Kogyo Ltd., beschichtet. Die Dicke dieser Beschichtung beträgt etwa 3 - 5 µm.The cylinder thus prepared is treated with a commercially available photoresist, for example, LD 100 from OHKA Kogyo Ltd., coated. The thickness of this Coating is about 3 - 5 microns.
Anschließend wird der Zylinder gegebenenfalls mit einem Overcoat mit einer Schichtdicke von 1 - 5 µm versehen, beispielsweise mit OC-40 der oben genannten Firma oder mit einer analogen ähnlichen handelsüblichen Zusammensetzung.Subsequently, the cylinder is optionally with an overcoat with a Layer thickness of 1 - 5 microns provided, for example, with OC-40 of the above mentioned company or with a similar similar commercial Composition.
Anschließend wird der Zylinder belichtet, beispielsweise mit einem Ar/Ne-Laser.
Zur Steuerung des Nullweitenpunkts und des Nordimpulses wird am Laser mit
Hilfe einer Optik und einer Kamera (CCD-Kamera) der Referenzpunkt
festgelegt.
Dabei werden die als Schutzschicht benötigten Teile belichtet. Üblicherweise
weist der Laserstrahl eine Werkzeugbreite von 5 µm auf, was einer Auflösung
von 40.000 Punkten/mm2 entspricht.Subsequently, the cylinder is exposed, for example with an Ar / Ne laser. To control the zero point and the north impulse, the reference point is determined on the laser with the aid of optics and a camera (CCD camera).
The parts required as a protective layer are exposed. Usually, the laser beam has a tool width of 5 μm, which corresponds to a resolution of 40,000 points / mm 2 .
Anschließend wird der belichtete Zylinder entwickelt, beispielsweise in einer Natriumcarbonatlösung (0,5% Lösung), daran schließt üblicherweise ein Reinigungsvorgang mit Wasser an, worauf der Zylinder getrocknet wirdSubsequently, the exposed cylinder is developed, for example in a Sodium carbonate solution (0.5% solution), this usually includes Cleaning process with water, whereupon the cylinder is dried
Der belichtete und entwickelte Zylinder wird nun auf die erste gewünschte Tiefe
mit einer CuCl2-Lösung geätzt, oder es wird mittels eines bekannten
galvanischen Verfahrens die Dicke der Kupferschicht an der Oberfläche
entsprechend reduziert.
Anschließend wird die erste Photoresistschicht entfernt, worauf wiederum ein
neuer Photoresist, wie oben beschrieben, aufgebracht wird, eine weitere
Belichtung erfolgt und anschließend die Ätzung bzw. der galvanische
Kupferabtrag auf die gewünschte zweite Tiefe erfolgt.
Auf diese Weise können unterschiedliche Tiefen auf dem Zylinder bzw. dem
Druckwerkzeug hergestellt werden. Das beschriebene Verfahren ist so oft
wiederholbar, bis man gegebenenfalls auf die Haftvermittlerschicht trifft.The exposed and developed cylinder is now etched to the first desired depth with a CuCl 2 solution, or the thickness of the copper layer on the surface is correspondingly reduced by means of a known galvanic process.
Subsequently, the first photoresist layer is removed, whereupon a new photoresist, as described above, is applied, a further exposure takes place and then the etching or the galvanic copper removal takes place to the desired second depth.
In this way, different depths can be made on the cylinder or the printing tool. The process described can be repeated until it is possible to encounter the primer layer.
Als erste Tiefe sind beispielsweise in Abhängigkeit von den gewünschten
Strukturen und der gewünschten magnetischen Codierung 10 - 150 µm,
vorzugsweise 12 - 80 µm, besonders bevorzugt 50 - 60 µm denkbar, für die
zweite Tiefe 10 - 150 µm, vorzugsweise 12 - 80 µm, besonders bevorzugt 30 -
40 µm denkbar.
Je nach Geometrie und Anordnung der Vertiefungen erfolgt im ersten Schritt
entweder die Erzeugung der größten Tiefe bzw. der geringsten Ätztiefe.Depending on the desired structures and the desired magnetic coding, 10-150 μm, preferably 12-80 μm, particularly preferably 50-60 μm, are conceivable as the first depth, for the second depth 10-150 μm, preferably 12-80 μm. particularly preferably 30-40 microns conceivable.
Depending on the geometry and arrangement of the depressions, either the generation of the greatest depth or the lowest etching depth takes place in the first step.
Dadurch ist ein optisch variables Sicherheitselement mit funktionellen Eigenschaften auf einfache Weise herstellbar. This is an optically variable security element with functional Properties can be produced in a simple manner.
Vorzugsweise sind die Pigmente jeweils in einer wässrigen oder lösungsmittelhaltigen Acrylat-Polymerdispersion (mit einem MG von 150.000 - 300.000) bzw. in einer Acrylat-Styrol- oder Acrylat-Urethan-Polymerdispersion oder in einem UV-Lack oder in Ethylenactylatcopolymer dispergiert. Als Lösungsmittel kommen dabei Wasser, Alkohole, wie i-Propanol, oder Methoxypropanol, Ester wie Ethylacetat, Ketone wie Methylethylketon, Aromate oder Aliphate und deren Mischungen in Frage.Preferably, the pigments are each in an aqueous or solvent-containing acrylate polymer dispersion (having a MW of 150,000 300,000) or in an acrylate-styrene or acrylate-urethane polymer dispersion or dispersed in a UV varnish or in ethylene actylate copolymer.

Die Aufbringung der Schichten kann jeweils durch ein beliebiges Verfahren, beispielsweise durch Tiefdruck, Flexodruck, Siebdruck, Offsetdruck, Digitaldruck, Glattwalzen-, Raster- oder Linienrasterverfahren, jeweils mit Mitoder Gegenlauf, und dergleichen erfolgenThe application of the layers may each be by any method, for example, by gravure printing, flexographic printing, screen printing, offset printing, Digital printing, smooth-roll, raster or line screening, each with co-orod Counter run, and the like
Das Trägersubstrat kann bereits funktionelle und/oder dekorative Schichten aufweisen oder es können anschließend weitere funktionelle und/oder dekorative Schichten aufgebracht werden.The carrier substrate may already have functional and / or decorative layers or it may subsequently be further functional and / or decorative layers are applied.
Diese Schichten können beispielsweise bestimmte elektrische, magnetische, chemische, physikalische und auch optische Eigenschaften aufweisen.These layers may be, for example, certain electrical, magnetic, have chemical, physical and also optical properties.
Zur Einstellung elektrischer Eigenschaften, beispielsweise Leitfähigkeit können beispielsweise Graphit, Ruß, leitfähige organische oder anorganische Polymere. Metallpigmente (beispielsweise Kupfer, Aluminium, Silber, Gold, Eisen, Chrom und dergleichen), Metalllegierungen wie Kupfer-Zink oder Kupfer-Aluminium oder auch amorphe oder kristalline keramische Pigmente wie ITO und dergleichen zugegeben werden. Weiters können auch dotierte oder nicht dotierte Halbleiter wie beispielsweise Silicium, Germanium Galliumarsenid oder Selen oder Ionenleiter wie amorphe oder kristalline Metalloxide oder Metallsulfide als Zusatz verwendet werden. Ferner können zur Einstellung der elektrischen Eigenschaften der Schicht polare oder teilweise polare Verbindungen, wie Tenside oder unpolare Verbindungen wie Silikonadditive oder hygroskopische oder nicht hygroskopische Salze verwendet oder zugesetzt werden.For adjusting electrical properties, such as conductivity can For example, graphite, carbon black, conductive organic or inorganic Polymers. Metal pigments (for example copper, aluminum, silver, gold, Iron, chromium and the like), metal alloys such as copper-zinc or copper-aluminum or also amorphous or crystalline ceramic pigments such as ITO and the like may be added. Furthermore, also doped or not doped semiconductors such as silicon, germanium gallium arsenide or Selenium or ionic conductors such as amorphous or crystalline metal oxides or Metal sulfides are used as an additive. Furthermore, to adjust the electrical properties of the layer polar or partially polar Compounds such as surfactants or nonpolar compounds such as silicone additives or hygroscopic or non-hygroscopic salts used or be added.
Die optischen Eigenschaften der Schicht lassen sich durch sichtbare Farbstoffe bzw. Pigmente, lumineszierende Farbstoffe bzw. Pigmente, die im sichtbaren, im UV-Bereich oder im IR-Bereich fluoreszieren bzw. phosphoreszieren, Effektpigmente, wie Flüssigkristalle, Bronzen und/oder Multilayer-Farbumschlagpigmente und wärmeempfindliche Farben bzw. Pigmente beeinflussen. Diese sind in allen möglichen Kombinationen einsetzbar. Zusätzlich können auch lumineszierende Pigmente allein oder in Kombination mit anderen Farbstoffen und/oder Pigmenten eingesetzt werden.The optical properties of the layer can be determined by visible dyes or pigments, luminescent dyes or pigments which are in the visible, fluoresce or phosphoresce in the UV range or in the IR range, Effect pigments, such as liquid crystals, bronzes and / or multilayer color change pigments and heat-sensitive colors or pigments influence. These can be used in all possible combinations. In addition, luminescent pigments may be used alone or in combination be used with other dyes and / or pigments.
Gegebenenfalls kann eine weitere magnetische Schicht vollflächig oder partiell
auf dem Substrat zur Verstärkung der magnetischen Eigenschaften vorhanden
sein oder anschließend aufgebracht werden.
Insbesondere geeignet sind Magnetfarben mit Pigmenten auf Basis von Cr/Ni-Stahl,
Al/Fe3O4 und dergleichen. Diese Magnetfarben zeigen im Gegensatz zu
den konventionellen Magnetfarben, die schwarz, braun oder grau erscheinen,
ein silbriges Erscheinungsbild und weisen gleichzeitig die oben beschriebenen
erforderlichen magnetischen Eigenschaften auf.
Dadurch ist es möglich, das für viele Anwendungen erwünschte bzw.
erforderliche metallisch glänzende Erscheinungsbild in einem Arbeitsgang
bereits durch Verdrucken dieser Magnetfarben zu erzeugen. Ein Überdrucken
bzw. Beschichten mit metallischen oder Metall-Schichten zur Erzeugung des
gewünschten Erscheinungsbildes ist daher nicht nötig, kann aber
beispielsweise zur Einbringung weiterer Identifikationsmerkmale problemlos
erfolgen.Optionally, a further magnetic layer may be present over the whole surface or partially on the substrate to enhance the magnetic properties or may subsequently be applied.
Particularly suitable are magnetic paints with pigments based on Cr / Ni steel, Al / Fe 3 O 4 and the like. These magnetic colors, in contrast to the conventional magnetic colors, which appear black, brown or gray, have a silvery appearance and at the same time have the required magnetic properties described above.
This makes it possible to produce the desired or required for many applications shiny metallic appearance in one operation already by printing these magnetic colors. Overprinting or coating with metallic or metal layers to produce the desired appearance is therefore not necessary, but can be done easily, for example, to introduce additional identification features.
Ferner können die erfindungsgemäßen Sicherheitselemente mit einer Schutzlackschicht ein- oder beidseitig versehen sein. Der Schutzlack kann pigmentiert oder nicht pigmentiert sein, wobei als Pigmente alle bekannte Pigmente oder Farbstoffe, beispielsweise Ti02, ZnS, Kaolin, ATO, FTO, Aluminium, Chrom- und Siliziumoxide oder beispielsweise organische Pigmente wie Phthalocyaninblau, i-Indolidingelb, Dioxazinviolett und dergleichen verwendet werden können.
