Abstract

Method involves providing uniform introduction into paper of microelement additives in the form of compounds of alkaline elements of Li, Rb, Cs as protection means; controlling presence of counterfeit protection means including analysis of mass of secondary ions forced out from paper by primary charged particle beam, i.e., accomplishing elementary and isotopic analysis at high localization making up to 0.1 micron; introducing microelement additives throughout the volume, over surface or into paper.

Description

Die Erfindung betrifft ein Verfahren zur Sicherung von Wertpapieren und kann bei der Produktion von Banknoten, Anleihen, Schecks, Tickets, Karten, Urkunden und anderen Arten von Wertpapieren verwendet werden, deren Echtheit ständig geprüft wird.The invention relates to a method for securing securities and can be used in the production of banknotes, bonds, checks, tickets, cards, certificates and other types of securities, the authenticity of which is constantly checked.

Es ist ein Verfahren zur Herstellung von gegen Fälschung geschütztem Wertpapier bekannt, das im Einbringen eines Sicherheitsmittels in das Papier und in der nachfolgenden Kontrolle auf dessen Vorliegen zwecks Wertpapierechtheitserkennung besteht (Patent RU Nº 2144216, 01.10.2000 - Analogieverfahren und Prototyp).A method is known for the production of counterfeit-protected securities, which consists in the introduction of a security agent in the paper and in the subsequent control of its existence for the purpose of securities authentication (Patent RU Nº 2144216, 01.10.2000 - analogy method and prototype).

Der Nachteil des bekannten Verfahrens zur Herstellung von gegen Fälschung geschütztem Wertpapier besteht in einer ungenügend wirksamen Sicherung aufgrund der einfachen Erkennung des Sicherheitsmittels.The disadvantage of the known method for the production of security against counterfeiting is an insufficiently effective security due to the simple detection of the security agent.

Das technische Ergebnis der Erfindung ist die Erhöhung der Fälschungssicherheit von Wertpapier durch Erschwerung der Kontrolle auf das Vorliegen des Sicherheitsmittels.The technical result of the invention is to increase the security against counterfeiting of securities by hindering the control of the presence of the security agent.

Das wird dadurch erreicht, dass als Sicherheitsmittel Spurenelementzusätze in Form von gleichmäßig eingebrachten Verbindungen der Alkalielemente Li, Rb, Cs verwendet werden und die Kontrolle auf das Vorliegen des Sicherheitsmittels die Analyse der Massen der sekundären Ionen umfasst, die aus dem Papier durch einen Strahl der primären geladenen Teilchen herausgeschlagen werden, und der Durchführung einer Elementen- und Isotopenanalyse in einem kleinen Flächenbereich mit einem Durchmesser von bis zu 0,1 µm.This is achieved by using as trace agents trace element additives in the form of uniformly introduced compounds of the alkali elements Li, Rb, Cs and the control of the presence of the security agent comprises the analysis of the masses of secondary ions coming from the paper through a beam of the primary charged particles and performing an elemental and isotopic analysis in a small area with a diameter of up to 0.1 microns.

Für die Massenanalyse (in Papierproben) wird die Sekundärionen-Massenspektrometrie (SIMS) verwendet.For mass analysis (in paper samples) secondary ion mass spectrometry (SIMS) is used.

Die Spurenelementzusätze werden in das Volumen und in das Papier eingebracht oder auf die Oberfläche aufgetragen.The trace element additives are incorporated into the volume and into the paper or applied to the surface.

Die Spurenelementzusätze werden in die Papierleimkomposition oder in die Druckfarbenrezeptur eingebracht.The trace element additives are incorporated in the paper size composition or in the ink formulation.

Das Wesen des Verfahrens zur Herstellung von fälschungssicherem Wertpapier besteht im folgenden.The essence of the method for producing counterfeit-proof security is as follows.

Der übliche technologische Prozess der Herstellung von Sicherheitspapier umfasst unter anderem auch Arbeitsgänge, die mit der Verwendung von Farbstoffen, Papierleim und Bindemitteln für die Druckfarben verbunden sind.The usual technological process of making security paper includes, among other things, operations associated with the use of dyes, paper size, and binders for the inks.

Bei der Herstellung wird in das Papier das Sicherheitsmittel eingebracht, und es wird eine Kontrolle auf dessen Vorliegen für die Echtheitserkennung von Wertpapier durchgeführt.During manufacture, the security agent is introduced into the paper and a check is made for its presence for the authentication of security.

Als Sicherheitsmittel werden Spurenelementzusätze (Mikrozusätze von Elementen) in Form von gleichmäßig eingebrachten Verbindungen der Alkalielemente Li, Rb, Cs verwendet.As a security agent, trace element additives (micron additives of elements) in the form of uniformly introduced compounds of the alkali elements Li, Rb, Cs are used.

Die Kontrolle auf das Vorliegen des Sicherheitsmittels umfasst eine Analyse der Massen der Sekundärionen, die aus dem Papier durch einen Strahl der primären geladenen Teilchen herausgeschlagen werden, unter Durchführung einer Element- und Isotopenanalyse in einem kleinen Flächenbereich mit einem Durchmesser von bis 0,1 µm.Control of the presence of the security agent involves analysis of the masses of secondary ions ejected from the paper by a beam of the primary charged particles, performing elemental and isotopic analysis in a small area of diameter 0.1 μm or less.

Für die Massenanalyse (in Papierproben) wird die Sekundärionen-Massenspektrometrie (SIMS)verwendet.For mass analysis (in paper samples) secondary ion mass spectrometry (SIMS) is used.

Die Spurenelementzusätze werden in das Volumen und in das Papier eingebracht oder auf die Oberfläche aufgetragen.The trace element additives are incorporated into the volume and into the paper or applied to the surface.

Die Spurenelementzusätze können in die Papierfarbstoffkomposition oder in einzelne Papierfasern eingebracht werden. Durch Variation der Gewichts- bzw. Molverhältnisse der drei zugesetzten Alkalielemente kann eine weitere Information im Papier gespeichert werden und die Fälschungssicherheit zusätzlich erhöht werden.The trace element additives can be incorporated into the paper dye composition or into individual paper fibers. By varying the weight or molar ratios of the three added alkali elements, a further information can be stored in the paper and the security against counterfeiting can be additionally increased.

Die Spurenelementzusätze werden z.B. in die Papierleimkomposition oder in die Druckfarbenbindemittel eingebracht.The trace element additives are used e.g. introduced into the paper size composition or in the printing ink binder.

Beispiel 1example 1

Bei der Herstellung des Sicherheitspapiers wird ein Gemisch von löslichen Verbindungen von Li, Rb, Cs in Konzentration von 10-4 - 10-6 g Alkalielemente pro g dem Leim zugegeben. Die erhaltenen Papierproben werden mit Hilfe von Massenspektrometrie auf das Vorliegen (oder die Intensität des Stroms der sekundären Ionen) dieser Elemente ausgewertet. Die gemessenen Verhältnisse von Massen oder Ionenströmen von Li, Rb und Cs werden als kontrollierbare (Pass) Kennwerte für die Identifizierung der Erzeugnisse aus dem gegebenen Papier benutzt.In the preparation of the security paper, a mixture of soluble compounds of Li, Rb, Cs in the concentration of 10 -4 - 10 -6 g alkali elements per g of the glue is added. The obtained paper samples are evaluated by mass spectrometry for the presence (or intensity of secondary ion current) of these elements. The measured ratios of masses or ionic currents of Li, Rb and Cs are used as controllable (pass) characteristics for the identification of the products from the given paper.

Die Erfindung ermöglicht es somit, den Grad der Sicherheit von Wertpapier und die Wirksamkeit der Kontrolle auf das Vorliegen des Sicherheitsmittels im Wertpapier zu erhöhen.The invention thus makes it possible to increase the degree of security of securities and the effectiveness of the control on the presence of the security agent in the security.

Industrielle Verwendbarkeit. Die Erfindung kann bei der Herstellung von Wertpapieren verwendet werden.Industrial availability. The invention can be used in the manufacture of securities.
