Abstract
The invention relates to a data carrier, e.g., a document of value, comprising a data carrier substrate and a security element applied to the data carrier substrate, wherein the side of the data carrier substrate having the security element defines the front side of the data carrier and the data carrier substrate has, in the area of the security element, areas having increased light transmittance and areas having reduced light transmittance, which together form a first motif; and the security element contains a transparent carrier substrate having a semi-transparent functional layer, wherein the semi-transparent functional layer is designed in such a way that (i) the data carrier has a first, visually detectable color when the front side of the data carrier is observed in incident light and has a second, visually detectable color when observed in transmitted light and (ii) the first motif is not perceptible when the front side of the data carrier is observed in incident light and is perceptible when the data carrier is observed in transmitted light.
Description
[0001] The invention relates to a data carrier, e.g. a value document such as a bank note, or a security element for securing a value document.
[0002] Data carriers, such as value documents or identification documents, or other objects of value, such as branded articles, are for securing often provided with security elements which permit a verification of the authenticity of the data carriers and which at the same time serve as protection from unauthorized reproduction.
[0003] In this connection there are known (transmission-view) security elements having multilayer thin-film elements which upon viewing in incident light, i.e. in reflection, appear in a first color and upon viewing in transmitted light, i.e. in transmission, appear in a second color. WO 2011/082761 Al describes a thin-film element with multilayer structure which appears gold-colored upon the viewing in incident light and blue upon the viewing in transmitted light. The multilayer structure is based on two semi-transparent mirror layers and a dielectric spacer layer arranged between the two mirror layers.
[0004] Any discussion of documents, acts, materials, devices, articles or the like which has been included in the present specification is not to be taken as an admission that any or all of these matters form part of the prior art base or were common general knowledge in the field relevant to the present disclosure as it existed before the priority date of each of the appended claims.
[0005] Throughout this specification the word comprise, or variations such as comprises or comprising, will be understood to imply the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, integer or step, or group of elements, integers or steps.
[0006] Some embodiments of the present disclosure aim to provie a data carrier of the kind referred to at the outset having high anti-forgery security and attractive visual appearance.
[0007] Summary [0008] In one aspect, there is provided a data carrier having a data carrier substrate and a security element applied to the data carrier substrate, wherein the side of data carrier substrate having the security element defines the front side of the data carrier and
2017217089 30 Apr 2019
- the data carrier substrate is a polymer substrate having in the region of the security element regions with elevated light transmission and regions with reduced light transmission which together form the first motif;
- wherein the regions with reduced light transmission are formed by regions printed with opaque ink of the data carrier substrate and the regions with elevated light transmission are unprinted regions of the data carrier substrate;
- the security clement contains a transparent carrier substrate having a semi-transparent function layer, wherein the semi-transparent function layer is constituted such that (i) the data carrier upon the viewing its front side in incident light has a first visually recognizable color and upon the viewing in transmitted light has a second visually recognizable color and (ii) the first motif is imperceptible upon the viewing of the front side of the data carrier in incident light and is perceptible upon the viewing of the data carrier in transmitted light; and
- the semi-transparent function layer of the security element has a multilayer construction with two semi-transparent metallic layers and a dielectric layer arranged between the two semitransparent metallic layers or is obtainable by printing technology by means of an effect pigment composition.
[0009] In another aspect, there is provided a data carrier having a data carrier substrate and a security element applied to the data carrier substrate, wherein the side of data carrier substrate having the security element defines the front side of the data carrier and
- the data carrier substrate in the region of the security element has regions with elevated light transmission and regions with reduced light transmission which together form the first motif; and
- the security element contains a transparent carrier substrate having a semi-transparent function layer, wherein the semi-transparent function layer is constituted such that (i) the data carrier upon the viewing its front side in incident light has a first visually recognizable color and upon the viewing in transmitted light has a second visually recognizable color and (ii) the first motif is imperceptible upon the viewing of the front side of the data carrier in incident light and is perceptible upon the viewing of the data carrier in transmitted light.
[0010] The first motif upon the viewing of the front side of the data carrier in incident light may be perceptible on the basis of lightness differences of the second, visually recognizable color.
[0011] The data carrier substrate may be a paper substrate and the regions with elevated light transmission are formed by means of thinned paper regions and the regions with reduced light
2017217089 30 Apr 2019 transmission are formed by means of thickened paper regions. The thinned paper regions and the thickened paper regions can form in particular a watermark.
[0012] The regions with reduced light transmission may be formed by regions printed with opaque ink of the data carrier substrate and the regions with elevated light transmission are unprinted regions of the data carrier substrate. The regions printed with opaque ink can form in particular a watermark generated by printing technology.
[0013] The alternatives described in the above items for the generating of regions with elevated or lowered light transmission, namely the thickened and thinned paper regions, on the one hand, and the regions printed with opaque ink and the unprinted regions, on the other hand, can furthermore be combined arbitrarily with each other.
[0014] The data carrier substrate may have in the region of the applied security element an elevated light transmission compared to the region outside the applied security element.
[0015] The data carrier substrate may be a paper substrate which is thinned in the region of the applied security element.
[0016] Such a thinning of the paper substrate in the region of the applied security element has the advantage that a relatively low intensity of the light source is enough for the achieving of the transmitted light effect.
[0017] The semi-transparent function layer of the security element may have a multilayer construction with two semi-transparent metallic layers and a dielectric layer arranged between the two semi-transparent metallic layers.
[0018] The two semi-transparent metallic layers may be formed independently of each other from a metal and the metal respectively is chosen from the group consisting of Al, Ag, Ni, Cr, Cu, Au and an alloy of one or several the hereinabove mentioned elements.
[0019] The two semi-transparent metallic layers may be chosen from Al or Ag and the dielectric layer is a S1O2 layer.
[0020] The semi-transparent function layer of the security element may be obtainable by printing technology by means of an effect pigment composition.
[0021] The security element may have additionally an emboss-lacquer layer having a relief
2017217089 30 Apr 2019 structure suitable for the forming of a micromirror arrangement.
[0022] The relief structure of the semi-transparent function layer may form a second motif which is perceptible to the viewer at least upon the viewing of the data carrier in incident light and preferably is perceptible upon the viewing of the data carrier in incident light as well as upon the viewing of the data carrier in transmitted light. The second motif may be generated in particular by the semi-transparent function layer which is adapted to the emboss-lacquer layer having a relief structure, so that the relief structure of the emboss-lacquer layer continues in the semi-transparent function layer.
[0023] The first motif and the second motif may supplement each other or be in a meaningful relation relative to each other.
[0024] The data carrier substrate in the region of the security element may have, in addition to the regions with elevated light transmission and regions with reduced light transmission which together form the first motif, a separate window region, in particular a recess or a through hole.
[0025] The recess or the through hole can in particular be present in the form of one or several microperforations, in particular obliquely extending microperforations.
[0026] The security element in the window region of the data carrier substrate may have an emboss-lacquer layer having a relief structure suitable for forming a micromirror arrangement and the relief structure of the semi-transparent function layer in the window region forms a (socalled third) motif which is perceptible to the viewer at least upon the viewing of the data carrier in incident light and preferably is perceptible upon the viewing of the data carrier in incident light as well as upon the viewing of the data carrier in transmitted light. The (so-called third) motif may be generated in particular by the semi-transparent function layer which is adapted to the emboss-lacquer layer having a relief structure, so that the relief structure of the embosslacquer layer continues in the semi-transparent function layer.
[0027] The security element may be a strip, thread or a patch or label.
[0028] The data carrier may be a value document, such as a bank note, in particular a paper bank note, polymer bank note or foil composite bank note, or an identity document such as an identification card.
[0029] The data carrier itself may be a security element for securing value documents.
2017217089 30 Apr 2019 [0030] The security element may be a strip, thread or a patch or label.
[0031] Detailed description [0032] The data carrier stated in the present description can be a value document, in particular a bank note, such as a paper bank note, a polymer bank note or a foil composite bank note, or a share, a bond, a deed, a voucher, a check, a high-value admission ticket, or an identity document or an identification card, such as a credit card, a bank card, a cash payment card, an authorization card, an identity card or a passport personalization side. Furthermore, the data carrier can be a security element, in particular a (security) patch or a (security) a label, a (security) strip or a (security) thread, for securing a value document.
[0033] A viewing in incident light as intended by this disclosure is an illumination of the data carrier from one side and a viewing of the data carrier from the same side. A viewing in incident light is thus present, for example, when the front of the data carrier is illuminated and also viewed.
[0034] A viewing in transmitted light as intended by this disclosure is an illumination of a data carrier from one side and a viewing of the data carrier from another side, in particular the opposite side. A viewing in transmitted light is therefore present, for example, when the back side of the data carrier is illuminated and the front side of the data carrier is viewed. The light thus shines through the data carrier.
[0035] The data carrier substrate of the data carrier, e.g. a value-document substrate, such as a bank-note substrate, is in particular a paper substrate or a paper-like substrate, a polymer substrate, a paper/foil/paper-composite substrate or a foil/paper/foil-composite substrate. A value document furnished with a window region or security paper can be generated in case of a paper substrate, a paper/foil/paper-composite substrate or a foil/paper/foil-composite substrate, e.g. by means of a continuous recess inside the paper layer(s). Alternatively, the paper layer can in a certain region be made transparent by means of a suitable liquid, e.g. by means of aqueous sulfuric acid solution. In case of a value document based on a transparent polymer substrate, a window region can be generated, e.g. by means of congruent recesses in the opaque printed layers applied to the front side and back side of the polymer substrate.
[0036] The semi-transparent function layer has different color tones upon the viewing in incident light, on the one hand, and upon the viewing in transmitted light, on the other hand.
2017217089 30 Apr 2019
The two different color tones are e.g. complementary colors. Such a semi-transparent function layer is based e.g. on a multilayer construction with two semi-transparent metallic layers and a dielectric layer arranged between the two semi-transparent metallic layers. Such a multilayer construction, which appears gold-colored upon the viewing in incident light, and shows a blue color tone upon the viewing in transmitted light, is known e.g. from WO 2011/082761 Al.
[0037] Suitable multilayer structures with two semi-transparent metallic layers and a dielectric layer arranged between two semi-transparent metallic layers typically have the following material constitution:
- the two semi-transparent metallic layers are chosen preferably by Al or Ag; the dielectric layer is in particular a S1O2 layer;
- in case that each of the two semi-transparent metallic layers is based on Al, the respective preferred layer thickness lies in a range from 5 nm to 20 nm, in particular preferably in a range from 10 nm to 14 nm; the dielectric S1O2 layer has preferably a layer thickness in a range from 50 nm to 450 nm, further preferably in a range from 80 nm to 260 nm and in particular preferably in a range from 210 nm to 260 nm, wherein the ranges from 80 nm to 100 nm and from 210 nm to 240 nm are particularly preferred specifically for the supplying of a gold/blue color change;
- in case that each of the two semi-transparent metallic layers is based on Al, the respective preferred layer thickness lies in a range from 15 nm to 25 nm; the dielectric SiCb layer has preferably a layer thickness in a range from 50 nm to 450 nm, further preferably in a range from 80 nm to 260 nm and in particular preferably in a range from 210 nm to 260 nm, wherein the ranges from 80 nm to 100 nm and from 210 nm to 240 nm are particularly preferred specifically for the supplying of a gold/blue color change;
[0038] The above-mentioned multilayer layer constructions make not only the generation of a semi-transparent function layer possible, which upon the viewing in incident light appears goldcolored and upon the viewing in transmitted light shows a blue color tone, but further color changes can be created depending on the choice of the layer thickness, in particular of the dielectric layer, e.g.
- in incident light magenta, in transmitted light bluish-green;
- in incident light turquoise, in transmitted light orange-yellow;
- in incident light gold, in transmitted light blue-violet;
- in incident light silver, in transmitted light violet.
[0039] The semi-transparent function layer can be obtained alternatively by means of an effect
2017217089 30 Apr 2019 pigment composition. Printed layers on the basis of an effect pigment composition, which upon the viewing in incident light show a different color than upon the viewing in transmitted light, in particular a gold/blue color change, a gold/violet color change, a green-gold/magenta color change, violet/green color change or a silver/opaque color change, are described e.g. in WO 2011/064162 A2. The pigments preferably have the longest dimension from end to end (longest dimension of edge length) in a range from 15 nm to 1000 nm and are based on a transition metal which is chosen from the group consisting of Cu, Ag, Au, Zn, Cd, Ti, Cr, Mn, Fc, Co, Ni, Ru, Rh, Pd, Os, Ir and Pt. The transition metal is preferably Ag. The aspect ratio (i.e. the ratio of the longest end-to-end dimension relating to the thickness) is preferentially at least 1.5, in particular in a range from 1.5 to 300. The ratio of the binding agent to metal pigment is preferably below 10:1, in particular below 5:1. In dependence on the choice of the aspect ratio of the pigment, its longest dimension from end to end and the setting of the pigment/binder ratio, the color can be adjusted upon viewing the printed layer in transmission and the color upon viewing in reflection (e.g. blue in transmission and silver, gold, bronze, copper or violet in reflection; furthermore also violet, magenta, pink, green or brown in transmission and different colors in reflection which depend on the choice of the pigment/binder ratio). Colors with gold/blue color change between reflection and transmission (in other words, between incident-light viewing and transmitted-light viewing) are stated e.g. in the examples 1, 2 and 3 of table 1 of WO 2011/064162 A2. Furthermore, example 4 shows a color with gold/violet color change, example 5 a color with green-gold/magenta color change, example 7 a color with violet/green color change and example 8 a color with silver/opaque color change.
[0040] According to an advantageous variant, the data carrier according to the present disclosure, e.g. a value document, contains a data carrier substrate furnished with a security element, wherein the security element has the following layer sequence:
a) transparent carrier substrate, e.g. polyethylene terephthalate (PET) foil;
b) where applicable, an emboss-lacquer layer which has in particular a relief structure forming a diffractive structure and/or a relief structure forming a micromirror arrangement;
c) a semi-transparent function layer, e.g.
cl) a first semi-transparent metallic layer, e.g., aluminum;
c2) a dielectric layer, e.g. SiCh;
c3) a second semi-transparent metallic layer, e.g. aluminum;
d) where applicable, an adhesive layer, e.g. a heat-seal coating which is suitable for the bonding of the security element with the data carrier substrate.
2017217089 30 Apr 2019 [0041] The above emboss-lacquer layer b) can furthermore have regions with relief structure and regions without relief structure.
[0042] The semi-transparent function layer stated in the above variant can alternatively be an Ag/SiCh/Ag construction instead of an AI/S1O2/ Al construction. According to a further alternative, the semi-transparent function layer is obtainable by printing technology by means of an effect pigment composition.
[0043] In principle, the data carrier substrate of the data carrier according to the present disclosure can be equipped with a further foil element on the side which opposes the side having the security element. In the simplest case, the further foil element is a transparent foil (a so-called back-side foil) and serves in particular for stabilizing the flatness of the data carrier in the security-element region. The further foil element can furthermore be additionally a carrier of security features, such as by printing technology (e.g. by means of effect pigments) obtainable security features or a hologram or a hologram-like security feature.
[0044] Further embodiment examples as well as advantages of the present disclosure will be explained hereinafter with reference to the figures, in whose representation a rendition that is true to scale and proportion has been dispensed with in order to increase the clearness.

[0058] In the present case, the bank-note substrate is a paper substrate which has inside the dashed region 20 a window region formed by an aperture or recess and has inside the dashed region 21 a lower thickness than outside the dashed region 21, i.e. it is thinned. Inside the thinned region 21 the bank-note substrate furthermore has a watermark, namely the numeral 50. The watermark is based on thinned paper regions and thickened paper regions.
[0059] The security element 19 has the following layers:
a) a transparent carrier substrate, namely polyethylene terephthalate (PET) foil;
b) an emboss-lacquer layer which has, on the one hand, regions having a relief structure forming a diffractive structure and/ or a micromirror arrangement and has, on the other hand, regions without relief structure;
c) a semi-transparent function layer, namely cl) a first semi-transparent aluminum layer;
c2) an S1O2 layer;
c3) a second semi-transparent aluminum layer;
d) a heat-seal coating which is suitable for the bonding of the security element with the bank note substrate.
[0060] The layers cl), c2) and c) form a semi-transparent function layer which upon the viewing in incident light appears metallically gold-colored and bluish upon the viewing in transmitted light.
[0061] Figure 7 shows the security-element region of the data carrier shown in Figure 6 along the B-B1 line in cross-sectional view according to an embodiment example.
[0062] The reference number 22 designates the paper substrate which is thinned inside the region designated with the bracket 23 and has a recess, i.e. a window region, inside the region designated with the bracket 24. In the thinned region 23, the paper substrate 22 has furthermore thickened areas 25 and thinned areas 26 which together form the watermark 50 in Figure 6. The security element 19 applied to the paper substrate contains a transparent carrier substrate 27
2017217089 30 Apr 2019 and an emboss-lacquer layer 28 which has, on the one hand, regions 28a having a relief structure forming a diffractive structure and/ or a micromirror arrangement and has, on the other hand, regions 28b without relief structure. In addition, the security element 19 has in some areas a semi-transparent function layer 29. The security element 19 is furthermore equipped with a heat-seal coating which is suitable for the bonding of the security element 19 with the bank-note substrate 22 (not shown in Figure 7).
[0063] The reference number 30 represents an optionally present back-side foil which is applied for stabilizing the flatness of the bank note 18 on the side of the bank-note substrate 22 opposing the security element 19.
[0064] The block arrows 31 and 32 represent respectively the view of the viewer onto the security element 19 in the watermark region 23 or the window region 24.
[0065] The block arrow 33 represents a relatively strong light source which is required for the perceptibility of the watermarks formed by the numeral 50 upon the viewing of the bank note 18 in the region 23 in transmitted light.
[0066] The block arrow 34 represents a relatively weak light source which is required for the perceptibility of the motifs formed in the window region 24. The motif is generated by the semitransparent function layer 29, which is adapted in the window region 24 to the emboss-lacquer layer region 28a having a relief structure. The relief structure of the emboss-lacquer layer continues in the semi-transparent function layer, so that the viewer perceives e.g. a micromirror arrangement in the window region 24.
