Abstract

A counterfeit-proof value document with a mark containing a composition that is made up of fluorescent compounds, including at least one inorganic photostimulated fluorescent compound that is excited by UV or visible spectrum radiation and that exhibits fluorescence in the visible spectrum when exposed to infrared radiation. An inorganic, anti-Stokes fluorescent compound that exhibits fluorescence in the visible spectrum when exposed to infrared radiation provides for the production, under consecutive or simultaneous irradiation, of a visually detectable dynamic effect in the form of a colour change, a flickering, a scattering of waves of brightness or the pulsation of an image on the security mark. An authenticity verification method involves the consecutive irradiation of a value document, and the visual detection of a dynamic effect. An authenticity verification device comprises sources of photoexciting and photostimulating radiation, a diaphragm for the formation of a pattern of the aforesaid radiation and a control unit. Furthermore, the optical axes of the two sources of radiation cross in the plane in which the value document security mark is situated.

10 The present invention relates to the production and circulation of documents protected from forgery, namely: to a valuable document having at least one sign of authenticity, made using a protective

15 marking, as well as to a method of authenticating a valuable document and to a device that implements this method.

The mechanisms of photoexcitation and photo-stimulation of luminescent compounds mentioned in the text of the present description are discussed in detail in the source (Fok V.A. “Introduction to kinetics of luminescence of crystallophosphors ”, Moscow: Nauka, 1964).

The mechanisms of anti-Stokes luminescence are examined in detail in the source (Chukova Yu.P. “Antistokes of luminescence and new possibilities for its application)) M .: Soviet Radio, 1980).

From the current level of technology, solutions are widely known that use anti-stokes luminescent compounds as protective markings on valuable documents.

A technical solution is known (US 4047033 A, 1977), according to which, to identify a valuable document, it is proposed to irradiate the protective mark with IR radiation pulses and record the mark response in the visible range of the spectrum. The disadvantage of this technical solution is that it is focused on the instrument method of controlling the authenticity of a valuable document and does not fully solve the task of increasing the security of a valuable document, since it does not provide visual verification when verifying the authenticity of a valuable document in circulation. A technical solution is known (GB 2258659 A, 1993) proposing to use certain anti-Stokes phosphors compositions or anti-Stokes phosphors with zinc sulfide phosphors to protect valuable documents. This solution also does not say anything about creating dynamic luminescent labels based on compositions with photostimulated phosphors and does not propose new methods for visualizing visible anti-Stokes and photostimulated luminescence upon PDC excitation.

Finally, a technical solution is known, set forth in patent RU 2137612 Cl, 1999, which also proposes to use anti-stokes compounds for the protection of valuable documents, including other luminescence colors besides green. For visualization, it is proposed to use a semiconductor laser or a semiconductor LED. However, nothing new, previously not set forth in previous patents, is given in this decision. There are also technical solutions that suggest using photostimulated luminescent compounds to protect valuable documents. For example, a technical solution is known (US 43871 12 A, 1983), which proposes to use luminescent compounds based on strontium sulfide activated by rare earth ions for visual verification of the authenticity of documents. However, this technical solution does not solve the technical problem, since it is not intended for building visual effects dynamically changing in space along the label field.

The closest analogue of the proposed technical solution is the source of information (FR 2554122 Al, 1985), which describes a valuable document and a method for controlling the authenticity of a valuable document. This prototype describes the use of luminescent (including anti-Stokes) compounds to create a luminescent protective label on a valuable document. It is proposed to visually register the stationary glow of the label with anti-Stokes luminescence when irradiated with a source of infrared radiation. Another technical result is sequential visual registration of the luminescence of the label under the influence of UV radiation, then visual registration of the same label under the influence of IR radiation, then comparison of the observation results and the conclusion on the authenticity of the valuable document.

This solution does not fully enhance the security level of a valuable document, since conventional stationary luminescence is well known in the art, is relatively easy to reproduce by selecting the appropriate simulators, and there is a large range of Stokes and anti-Stokes luminescent substances available for sale and potentially available for counterfeiting.

Disclosure of invention

The technical task of the invention is to increase the degree of security of valuable document from falsification due to the use at the stage of control of a protected valuable document of a visually recorded dynamic effect consisting in color changing, flashing, scattering of brightness waves or ripple of the image of the protective marking when observing a valuable document in the visualizer.

Unlike all the known technical solutions cited, this technical solution uses dynamically changing visual effects of luminescence, such as color change, flashing, scattering of brightness waves or ripple of the image of the protective marking, to solve the problem. The importance of the presence of dynamic visual effects for solving the task of increasing the degree of security of a valuable document from falsification is explained by the advantage that arises when using the possibilities of visual perception of a person for whom the stationary glow of protective marking it is much easier to imitate than the nature of the dynamic change of the latter.

Improving the security of the document according to the proposed technical solution is achieved due to the fact that a valuable document protected from falsification, containing in its composition and / or on its surface a protective marking comprising a composition of luminescent compounds, is characterized in that the composition of luminescent compounds contains at least one inorganic photostimulated luminescent a compound brought into an excited state under the influence of radiation of the UV or visible range of the spectrum and having luminescence in the visible range by IR radiation and at least one inorganic anti-Stokes luminescent compound having luminescence in the visible spectrum under the influence of IR radiation and provides, when the UV and / or IR radiation is sequential or simultaneous, and / or visible spectral range obtaining visually recorded dynamic the effect of changing color, flashing, scattering of waves of brightness or ripple of the image of the protective marking.

A valuable document is a banknote, an excise stamp, a passport, a travel document, a driver’s license, an identification card, security paper, a plastic card, and the security marking includes a composition of luminescent compounds containing a photostimulated luminescent compound having luminescence under the influence of IR radiation with a wavelength of 0, 95 microns or 0.85 microns.

Protective labeling may include a composition of luminescent compounds containing a photostimulated luminescent compound having luminescence when irradiated simultaneously or sequentially or alternately in two or more regions of the near IR region of the optical spectrum in the wavelength range from 0.7 to 2.0 μm, preferably at lengths waves of 0.95 microns and 0.85 microns. Photostimulated luminescent compound can be selected from the group:

or (Me ^and i _-X-У Ln ' _x Ln ¹ V) _n , Me ^ш _n θ _{n +} i, _{5 m} , where: Me ¹¹ is at least one of the elements of the 2A-support (Mg, Ca, Sr, Br); Me ¹¹¹ - at least one of the elements of the subgroup (In, Ga, Al); Ln ¹ -Eu;

Ln ¹¹ is a rare earth element; l-10 ^"5 <x <5-10 ^"2; H0 ^"5 <y <5-10 ^"2; m, n are formula coefficients, (preferably (Sri _-xy Eu _x Dy _y ) ₄ Al ₁₄ θ ₂ 5 where l-10 ^"5 <x <5-U ^'2 ; l-10 ^{" 5} <y <5-10 ^"2 )

Me "-Al, Ga, In; l-10 ^{" 5} ≤x <5-10 ^'2 ; 1 10 ^"5 ≤y <5-U ^{" 2} , and the anti-Stokes luminescent compound is selected from the group:

0.001,

(Yi _-xy Yb _x Er _y ) ₃ OCl ₇ where 0.2 <x <0.4; 0.001 <y <0.3. The photostimulated luminescent compound and the anti-Stokes luminescent compound may further comprise cerium. Protective labeling may include a composition of luminescent compounds, which are particles of one fraction, each particle containing a photostimulated luminescent compound and an anti-Stokes luminescent compound and is a two-layer structure in which a photostimulated luminescent compound forms a shell for an anti-stokes luminescent compound, as well as each part the compound is a two-layer structure in which anti-Stokes the luminescent compound forms a shell for the photostimulated luminescent compound. The protective marking can have stationary UV luminescence with a long (more than 0.1 sec.) Afterglow time and can be performed by the printing method, preferably by metallographic or screen printing, or the protective marking is embedded in the paper mass and / or in the paper sizing, in the protective fiber introduced into a mass of paper. The security marking may be applied to security thread or confetti inserted into the paper or located at least partially on the surface of the paper, embedded in plastic or applied to the surface of the plastic.

The technical result is also achieved by a method of verifying the authenticity of a security document against falsification by sequentially irradiating the security document with UV or visible spectrum for at least 0.1 sec., And then with the infrared spectrum and visual registration of the dynamic effect of the color change flashing, scattering of waves of brightness or ripple of the image of the protective marking. In this case, irradiation of a valuable document in the near infrared range of the spectrum is carried out by radiation with a wavelength of 0.95 μm or 0.85 μm.

A valuable document can be irradiated simultaneously, either sequentially or alternately in two or more regions of the near infrared range of the spectrum in the wavelength range from 0.7 to 2.0 μm, preferably at wavelengths of 0.95 μm and 0.85 μm. The result is also ensured by the use of an authenticity check device for security of a valuable document containing a photoexcitation radiation source, a photo-stimulating radiation source, a diaphragm for forming a radiation pattern of said radiation, and a control unit for switching radiation sources on and off, while the optical axes of both radiation sources intersect in the plane of location protective marking of a valuable document. It may contain a photoexcitation radiation source with a maximum radiation power density in the UV spectral range for photoexcitation of the protective marking and a photostimulating radiation source with a maximum radiation power density in the near IR spectral range, preferably at a wavelength of 0.95 μm, for photo stimulation and photoexcitation of the protective marking or at a wavelength of 0.85 microns. The device may contain two emitters with maxima of the radiation power density in the near-IR spectral range with wavelengths of 0.95 μm and 0.85 μm for simultaneous, sequential or alternate photo-stimulation and photoexcitation of protective markings, as well as an element that prevents contact with the valuable document of external illumination and positioning element of a valuable document in the form of an emphasis.

As sources of photoexciting and photo-stimulating radiation, semiconductor LEDs can be used.

The dynamic effect, based on various mechanisms of excitation and luminescence of photostimulated and anti-Stokes luminescent compounds, can, in particular, consist in an intense short-term flash during stationary IR excitation of a photostimulated luminescent compound with a subsequent change in the color of the image’s glow protective marking due to mixing with the color of the luminescence of the anti-Stokes phosphor.

The resulting dynamic visual effect may consist in the apparent visually recorded runaway of the luminescence brightness waves from the center to the edges of the image of the protective markings.

A dynamic visual effect can also consist, depending on the selected RG mode of excitation of the authenticity control device (visualizer), in the pulsation or flickering of one or more graphic elements, possibly hidden under normal lighting, in the image of the protective marking against the background of a stationary glow of another graphic element or several elements in the image of the protective marking.

Considering that the mechanisms of excitation and emission included in the protective labeling of photostimulated and anti-Stokes luminescent compounds are based on the fundamental laws of physics, these dynamic effects are of a given and reproducible nature. Moreover, the ratio of photostimulated and anti-Stokes luminescent compounds in the composition of the marking is selected on the basis of ensuring optimal conditions for visual registration of the dynamic effect.

The composition of the protective marking may vary depending on the quantum yield of the luminescent compounds used and on the required brightness and color characteristics of the dynamic visual effect.

Considering the technological features of printing inks, the permissible content of inorganic pigments in the ink, forming a special protective marking, cannot, as a rule, exceed 20 - 25%.

The paint forming a special protective marking can contain both a mechanical mixture of inorganic pigments (photostimulated and anti-Stokes luminescent compounds), and particles of one fraction synthesized in such a way that they simultaneously have photostimulation properties and anti-Stokes properties, moreover, in the latter case, the particles of the luminescent compound are a two-layer composition in which one of the luminescent compounds forms a shell or capsule to protect against external influences of the other phosphor (claim 9).

In the present technical solution, the following percentages of luminescent compounds in the protective marking (photostimulated: anti-Stokes) were practically used and had good visual indicators: 50%: 50%, 60%: 40%, 80%: 20%.

The security marking may preferably have the shape of a die, the shape of a circle, the shape of concentric circles, concentric polygons, the shape of diverging rays, or a combination of these figures, be a guilloche element and have a total size of not more than 100 mm, preferably not more than 10 mm.

Example 1

A method for verifying the authenticity of a valuable document containing on its surface a special protective marking applied by the printing method containing a composite luminescent compound consisting of 80% of a photostimulated luminescent compound of the composition (Sr _1-xy Eu _x Sm _y ) S, where x = 1 - 10 ^"2 ; y = 1-U ^{" 2} and 20% of the anti-Stokes luminescent compound Y _2-xy Yb _x Er _y O ₂ S, where x = 0.2; y = 0.1. The control is carried out as follows: a valuable document is irradiated with photoexciting radiation in the UV range of the optical spectrum with a maximum spectral power density of 365 nm for a time interval of at least 0.1 sec. Then the effect of this radiation is stopped and, after a pause of 0.2 seconds, a valuable document is irradiated with photostimulating radiation in the IR range of the optical spectrum with a maximum at a wavelength of 0.8 μm. Visually the dynamic effect arising in this case is recorded, which consists in a color change from orange to green, accompanied by flashing and scattering of waves of brightness of orange color from the center to the edges of the observed marking area. Example 2

Used valuable document containing on its surface a special security marking deposited printing method comprising composite luminescent compound consisting of 60% fotostimuliruemogo luminescent compound composition Zni _-X-Y Cu _x Al _Y S, where x = 5-10 ^"and = -10 ^"2 and 40% of the anti-Stokes luminescent compound Y _2-xy Yb _x Er _y 0 ₂ S, where x = 0.2; y = 0.1. In this case, under the influence of UV radiation, the protective marking had stationary luminescence with visually recorded afterglow.

When controlling a valuable document, photostimulation was carried out alternately, in two regions of the near RJ of the optical region spectrum with wavelengths of radiation maxima of 0.95 microns and 0.85 microns.

The control consisted in visual registration of the pulsation effect with color change of luminescent radiation along the marking field.

Example 3

Repeats Example 1, but the composition of the photostimulated luminescent compound

(Sr _1-xy Ce _x Sm _y ) S, where x = 5-10 ^"4 ; y = 1-10 ^{" 4} , and the anti-Stokes luminescent compound is selected

Y _2-xy Yb _x Ho _y O ₂ S, where x = 0.2; y = 0.03.

When verifying the authenticity of a valuable document, a visualizer was used that provides optimal conditions for photoexcitation and photo stimulation of the protective marking, as well as optimal conditions for visual recording of the dynamic effect, which consists in color change, flashing, scattering of brightness waves or ripple of the observed protective marking image. The visualizer provides illumination of the protective marking in the given spectral ranges by radiation with optimal power, and in a certain time sequence. The defining feature of this device is the almost complete absence of visually observed dynamic effects on traditional protective markings known from the prior art, for example, stationary luminescence under the influence of UV radiation, or stationary anti-Stokes luminescence.

In FIG. 1 shows an optical diagram of the inventive device for authenticating a valuable document protected from forgery. In FIG. 1 shows: a photostimulating radiation source 1, a light filter 2, a radiation pattern 3, a capacitor 4, a photoexciting radiation source 5, a light filter 6, a condenser 7; a light cone 8 containing about 10% of the power of the source 1; a light cone 9 containing approximately 90% of the power of the source 1. On the diagram shows the location of the security marking 10 and valuable document 11 on which the security marking is located.

The device may also contain an electronic control unit for automatically turning on and off the above radiation sources in a given time sequence, a device for protection from extraneous illumination, a device for positioning the sample. The device operates as follows: first, a valuable document is sequentially irradiated with photoexciting radiation with a maximum wavelength lying in the UV or blue region of the optical spectrum for at least 0.1 sec, and then it is irradiated with photostimulating radiation with a maximum wavelength lying in the near IR the range of the optical spectrum, with the simultaneous visual registration of the resulting dynamic effect, which consists in changing colors, flashing, scattering of waves of brightness or ripple from mapping security marking on a value document. An increase in the degree of security of a valuable document from forgery when using the authentication method proposed in this invention is achieved due to the presence of a visually recorded effect consisting in flashing or ripple of the image of the security marking, as well as the resulting color and spatial transitions of brightness over the area of the security marking, dynamic the nature of which is reliably recorded by the human eye, which allows the use of this invention to control authentic validity of valuable documents at the consumer and cash level of circulation, with authenticity control by wide sections of the population. The visual dynamic effect observed on the device depends on the composition of the security label - various combinations of photostimulated phosphors and anti-Stokes phosphors, for example, a stationary green glow, scattering red rays; stationary green glow, scattering orange rays; stationary red light scintillating green rays stationary light orange glow, scattering red rays.

The weight ratio of the photostimulated and anti-Stokes phosphors in the security label as a percentage is preferably 50%: 50%, or 60%: 40%, or

80%: 20%.

Industrial applicability

The proposed technical solution has the following advantages in comparison with the prototype: the proposed technical solution is focused on creating protective markings with a dynamically changing visual effect, consisting in changing color and brightness in space, the combination of the properties of the luminescent compounds visually detected by the human eye is selected in this way, that the excitation regions of the anti-Stokes substance and the photostimulated phosphor coincided, that makes them function as a single radiating medium. This feature allows us to achieve in the proposed technical solution the simultaneous interaction of two different physical phenomena, which are photostimulated and anti-Stokes luminescence, which, in turn, leads to the appearance of a qualitatively new, visually observed dynamic effect. - the design of the visualizer provides such a radiation pattern of photostimulating radiation, in which dynamic effects are observed in the form of flashing at the time of IR excitation, followed by a time change in the color of the glow of the protective marking and is accompanied either by the scattering of the waves of brightness along the field of the protective mark from the center to the edge, or ripple image protective markings.
