Definitions
- the invention relates to a marking composition, in particular for the marking of textiles.
- An invisible security marker can be reached in several ways.
- An approach already followed is the use of photochromic substances, eg. As fluorophores that emit when irradiated with UV light a specific color in the visible range or in particular in the NIR range.
- the most important approaches to photochromic substances already pursued are explained below.
- EP 1 670 868 B1 describes fluorescent dyes or inks which contain so-called carbon nanotubes (CNTs) and are used in particular for safety applications.
- CNTs carbon nanotubes
- the applied inks fluoresce, emitting radiation in the NIR range.
- the applied inks are less visible, but can be detected with a suitable NIR camera.
- goods are treated with inks which are invisible to the observer under light from the visible spectrum and fluoresce only after irradiation with light of a different, shorter wavelength. This makes the markings or images printed with this ink visible and detectable.
- the inks described in EP 0 997 503 Bl are distinguished, inter alia, by a high level of print quality, excellent light and water fastness, excellent fluorescence intensity during illumination with a suitable light source and a high degree of reliability in connection with inkjet printing systems.
- EP 0 663 429 B1 describes invisible safety inks with the naked eye which, however, can be made detectable by irradiation with light in the infrared range.
- a phthalocyanine dye is used as the fluorophore in a binder matrix, preferably carnauba wax.
- EP 0 997 503 B1 and EP 0 663 429 B1 using fluorescent substances are in principle unsuitable for the security marking of textiles since they would be partially visible in intense sunlight. Fluorescence in the NIR range would also be unsuitable as a safety marker for many darker, black or, for example, blue-colored substrates of any type, for example with Cu phthalocyanines, because of the inherent absorption of the background and the resulting too low contrasts.
- a disadvantage of these photochromic or fluorophore substances is that they are often relatively unstable to UV light, so that their durability in outdoor applications, such as clothing and technical textiles, is doubtful.
- US 2007/0082963 A1 describes IR-absorptive inks which contain, among other things, antimony-doped tin oxide (ATO) and are distinguished by an only slightly visible color and a high IR absorption.
- ATO antimony-doped tin oxide
- inks which contain only the infrared absorbing semiconductor materials described in WO 2004/003070 Al or the tin oxide compounds described in DE 198 46 096 A1 or pigments generally absorbing in the NIR range, regardless of their particle size, can not be universally applied to different Substrates are used for decodable markings.
- Such inks which include, for example, only nanoscale IR-absorbing substances, are so far hardly used for the protection of brand name, for example, for high-quality textiles, since the high demands on the permanence of the markers, the visual invisibility and the requirements with respect to differently colored Substrates for decoding necessary contrasts are not sufficiently fulfilled.
- Object of the present invention is to propose a marking composition with which a better protection of goods than previously available, especially regardless of their color, can be achieved.
- marking composition according to the invention can be visually invisible, but nevertheless easily detectable markers produce, especially on textiles.
- a visually invisible marking which, however, can be detected and decoded by detection in a specific wavelength range of the IR spectral range, for example using suitable cameras, represents a suitable solution for security markings of any kind.
- markings which can be produced with marking compositions according to the invention and which are inconspicuous in the visible spectral range, in particular appear to be transparent, are of particular advantage, in particular for the application of security markings on textiles.
- the growing need for invisible, hidden security features in banknotes, identification and identification papers and credit cards can also be covered by the marking composition according to the invention, so that the security against counterfeiting will also be guaranteed in the future and, thus, for example. as the entry or the access of unwanted persons can be prevented.
- the invention thus covers an increasing demand in the Western industrialized nations and a strong interest in as simple as possible and cost-effective to apply visually invisible markings of products, which then with special readers, for example, from the regulatory side, recognized in a simple manner, read and can be decrypted by sending the encoding to specific databases.
- special readers for example, from the regulatory side, recognized in a simple manner, read and can be decrypted by sending the encoding to specific databases.
- the synergistic emission effects in the far-infrared range were found in the marking composition according to the invention.
- a light emission source is preferably used, which has a higher proportion of NIR radiation with a wavelength up to about 2 pm.
- NIR near infrared region
- FIR far-infrared detection
- excitation often has to take place in this area of the light, i. the excitation must take place at different times, for example by flashes of light, before the detection.
- the strength of the excitation as well as the time frame of the subsequent detection as well as the marking itself must hitherto be specifically optimized and coordinated with one another as a result of the different absorption properties. This is difficult and feasible in practice even with relatively large technical effort.
- the mixture is present as finely dispersed particulate mixture.
- the mixture according to the invention can be dispersed into a liquid, which in particular may be of low viscosity and which may additionally contain an organic component, in particular a polymeric binder component.
- a liquid which in particular may be of low viscosity and which may additionally contain an organic component, in particular a polymeric binder component.

- the doping content is about 0.25 to about 15 wt .-% based on the weight of the doped tin oxide.
- the carbon derivative as the second of the two components of the marking composition of the invention is preferably selected from allotropic forms of the element carbon such as carbon blacks, graphite, fullerenes, graphenes and the so-called carbon nanotubes, their derivatives and mixtures of the aforementioned carbon derivatives.
- the weight ratio of the infrared absorbing component to the carbon derivative is in the range of about 25: 1 to about 10,000: 1, preferably about 50: 1 to about 5,000: 1, more preferably about 80: 1 to about 2,000 : 1, most preferably from about 100: 1 to about 2,000: 1.
- the size of the particles in the marking composition according to the invention is preferably chosen so that the particle size index d 50 of the infrared absorbing component is about 500 nm or less, in particular about 100 nm or less and more preferably about 70 nm or less, most preferably about 50 nm or less.
- the carbon derivative is preferably in the form of nanoparticles having an extension in at least one direction of about 100 nm or less.
- the marking composition according to the invention can be formulated in particular as a flowable mass and then contains a liquid component.
- the flowable mass is formulated water-based.
- the marking composition according to the invention with a liquid component can also be formulated as a paste.
- the flowable composition is formulated as a low-viscosity liquid, in particular with a viscosity of about 25 mPas or less, more preferably from about 0.5 to about 20 mPas and most preferably with a viscosity of about 0.5 to about 5 mPas.
- the stated viscosity values are based on a shear rate of 1 s -1 .
- the flowable composition of the present invention particularly contains a solids content of the infrared absorbing component of from about 0.01 to about 10 weight percent, more preferably from about 0.05 to about 1 weight percent, and most preferably about 0.1 to about
- the marking composition formulated as a flowable composition may comprise a liquid component in the form of a monomeric, oligomeric and / or polymeric organic component, wherein the concentration of the organic component in the marking composition is in particular about 0.5 to about 30% by weight, more preferably about 1 to about 20 wt%, and most preferably about 2 to about 10 wt%.
- the organic components optionally used in the marking composition according to the invention formulated as a paste or flowable composition preferably comprise a compound having a molecular weight of about 300 to about 15,000 g / mol, more preferably about 500 to about 8,000 g / mol and on most preferably from about 800 to about 6,000 g / mol.
- the marking composition of the invention formulated as a paste or as a flowable composition preferably comprises a liquid component one or more polymers and / or copolymers selected from the polymer classes of polyethers, polyvinyl alcohols, polyacrylates, polystyrenes, polyurethanes, polyvinylcaprolactams, cellulose and / or polyvinylpyrrolidones.

- the water-based inks preferably used for the marking compositions according to the invention often result in lower crosslinking of the binder formulation used to fix the marking, which has a negative effect on the straight with markings has so significant permanence.
- the applied markings lose contrast, transparency and color neutrality and are no longer universally applicable as invisible markings.
- UV-curing systems with reactive diluents as formulation constituents are also less suitable, in particular, for the labeling of textiles because of the skin-sensitizing and irritating properties of the reactive diluents.
- the marking composition according to the invention is furthermore preferably formulated as an aqueous ink formulation and not, as recommended in US Pat. No. 8,157,905 B2, as an oleophilic composition, since solvent additions can largely be dispensed with in order to take account of environmental aspects.

It also follows that this is not only a purely additive but a synergistic amplification effect for the absorption in the NIR range of the
- the ink preparations in this example were prepared using the Hydrosol 900-based aqueous binder dispersion described above, wherein in the comparative example 5% by weight of the nanoscale antimony-doped tin oxide (ATO) component, based on the solids content of the polymeric binder, was added.
- ATO nanoscale antimony-doped tin oxide
- 50 ppm of flame black (Printex U) or 50 ppm of MWCNT (Nanocyl NC 7000) were used, based in each case on the solids content of the polymeric binder , added.
- weight ratios of the infrared absorbents are recommended. Even at such extremely low levels of the carbon derivative of the marking composition, as shown in Example 4, a marked synergistic effect can be observed.
- the chromaticity differences of the prints of the ink preparations containing only the nanoscale antimony-doped tin oxide (ATO) component (white bars) measured with the X-rite MA68 colorimeter (X-Rite Inc.) were compared with the color value differences of the imprints of the Inks with the finely divided mixtures according to the invention, which contain the nanoscale antimony-doped tin oxide (ATO) sample mixed with flame black (hatched bar) or with MWCNT (black bar), compared with unprinted white paper compared.
- the angles given as the X-rite measurement geometry represent the angular distance from the glancing angle.
- imprints of the formulations mentioned in the examples are transparent and neutral in color.
- the imprints relating to the number of overprints and the print density (dpi) were made such that for the prints of the ink preparations, which contain only the conventional nanoscale, antimony-doped tin oxide (ATO) component (comparative example, white bar), a color difference ⁇ of about 1 to the white paper was obtained at an X-rite measurement geometry of 45 °.
- ATO antimony-doped tin oxide
- the corresponding prints were carried out with analogous printing parameters, ie. the number of overprints and the print density (dpi) were the same as in the comparative example containing only the ATO.
- the color value differences ⁇ are given in FIG. 4 for the visible wavelength range from 400 to 720 nm. It can be seen that the prints of the inks, which contain the finely dispersed mixtures of tin oxide according to the invention as the infrared absorbing component with the carbon derivatives, change color only insignificantly over different viewing angles.
- the percentage color changes in the visible range are the percent contrast changes obtained after excitation in the NIR range near infrared (NIR: 720 to 2500 nm) and far infrared (FIR: 2.5 to 14 pm) detection range.
