JP4661279B2 - Non-aqueous genuine stain contamination ink - Google Patents

Description

  The present invention relates to an ink that contaminates a genuine note taken by an unauthorized means from a device installed in a financial institution, a post office, a station, a lottery sales office, or the like and cannot be used.

  Banknotes, securities, postage stamps, revenue stamps, tickets, certificates with winning money (hereinafter referred to as true tickets) are illegally stolen from financial institutions, post offices, stations, lottery sales offices, etc. that handle these by robbery. May be. In anticipation of such fraudulent deeds, an actual fraudulent deprivation is prepared in advance in the above financial institution or the like, in which a jet or a resin container that can be easily destroyed is filled with a fluorescent dye of a conspicuous color such as yellow or orange. In the event of an act, triggering the injector toward the criminal or genuine note, throwing the container and destroying the container, attaches the fluorescent dye to the criminal or genuine note, and can easily track the criminal Attempts have been made to do so. However, there are not a few cases in which the criminal ran away from the pursuit and escaped, and if the escape was successful, it is important that the genuine note taken illegally can be easily identified from the other genuine bills.

  Conventionally, fluorescent dyes used for genuine stains are similar to the color of office use markers called so-called fluorescent pens, so even if the color is attached to the genuine note, the genuine note is immediately improper. It was not easy to recognize that it was a genuine note taken by means. In addition, fluorescent dyes used for genuine stains are inferior in weather resistance and chemical resistance, so discoloration will occur if the contaminated genuine stains are exposed to sunlight or immersed in an alkaline or acidic solution. As a result, the genuine note can no longer be recognized as a genuine note taken by fraud.

  In addition, today, automatic teller machines, money changers, vending machines, etc. are widely used. The money changers, etc., are misused to contaminate genuine bills that have been contaminated when taken by illegal means. It is also possible to purchase goods with a vending machine using genuine bills that have been exchanged for genuine bills, etc., or that have been polluted by illegal means. Therefore, it is not enough to allow a person to recognize that it is a genuine note taken by illegal means, and it is strongly possible to identify it as a genuine note taken by illegal means mechanically. It is desired.

  By the way, genuine bills such as banknotes, securities, tickets, and certificates with winnings are counterfeits (hereinafter referred to as counterfeit tickets) that are made to resemble these genuine bills by magnetic treatment with printing ink, and sometimes magnetic ink. Are distinguished by magnetic and various optical sensors. Therefore, it is possible to identify a genuine note that has been illegally taken by contaminating the genuine note with genuine note-contaminating ink and changing the magnetic and optical characteristics.

  Also, since pigments are generally much better in weather resistance and chemical resistance than fluorescent dyes, it is possible to leave evidence of fraud on a genuinely taken bill for a long time.

  However, since the genuine stain-contamination ink used so far uses water as a solvent, the paper swells at the attached end face and the penetration is insufficient, and the original performance may not be exhibited.

  In addition, when a fraudulent act is taken, genuine stain-polluting ink must be urgently and quickly ejected from its storage member and adhere to the genuine note, which must be contaminated. It is difficult to urgently and quickly eject from the housing member. Furthermore, even if it adheres to the surface or end face of a genuine note, it is difficult to quickly penetrate into the inside. Alternatively, genuine bills can be contaminated by introducing genuine bills into genuine stain ink in the event of fraudulent piracy. In this case, genuine stains are contaminated as compared to the case of jetting genuine stain ink. The ink for use may have a high viscosity, but even if it adheres to the surface or end face of a genuine note, it has a problem that it does not readily penetrate into the inside. That is, if the magnetic ink does not penetrate into the inside of the genuine note and simply adheres to the surface or end face, the criminal etc. can easily remove the dirt after the fraudulent act, and then the fraudulent act It becomes impossible to recognize that the obtained genuine note is used, and the use of the genuine note cannot be prevented.

  Therefore, it is stable for a long period of time without special stirring so that the ink can be ejected urgently and promptly from the ink containing member and can penetrate quickly into the genuine paper. In order to maintain the dispersed state, if the genuine note is made of a permeable material such as paper, it is important that the contamination not only stay in the surface layer but also reach the inside. In order to ensure permeability, the viscosity is desirably 1 to 100 CPS (25 ° C.).

  In addition, since the money changer is often installed in an unattended situation, it is necessary to pay close attention to its safety. Therefore, it is desirable that the device does not contain substances that are easily ignited by static electricity or lightning strikes. Therefore, it is desirable that the genuine stain-contaminating ink is water-based.

However, a new problem has arisen in that it is extremely difficult to rapidly infiltrate the contaminants from the end face of the “bundle” of genuine bills into the inside of the genuine bills by using water-based genuine stain ink. When water-based genuine stain ink is attached to the end face of the genuine “bundle”, it seems that the genuine note itself swells, but the side to which the stain ink is attached is extremely swollen and the inside of the genuine note Contaminants will hardly permeate. Generally, a genuine note such as a banknote is often provided with magnetic printing for authenticity identification about 10 to 20 mm from the edge. Therefore, it is required that the stain ink penetrates about 20 mm from the end face of the genuine “bundle” toward the inside. However, if water-based genuine stain ink is used, magnetic printing for authenticity identification is sufficient. The ink does not penetrate inside the genuine note to the extent that it is contaminated.

  The present invention is stable for a long period of time without special stirring in a genuine note storage device in which genuine notes are stored in a kind of “bundle” state in which long sides and short sides are aligned and stacked or arranged. Ink that can maintain a dispersed state and is difficult to ignite due to static electricity, lightning strikes, etc., and can quickly and reliably contaminate the end face of a genuine “bundle” when the genuine note is taken away by unauthorized means. After the end face of the “bundle” of genuine bills is contaminated, it quickly penetrates into the inside of the genuine bill, and when the genuine bill is taken away by unauthorized means, the money change machine etc. The purpose of this machine is to provide genuine stain-contaminating ink that can leave long-term evidence on the genuine note that it is recognized that it is a genuine note taken by fraud. Make it impossible to use genuine bills And an object thereof.

  That is, the present invention is a non-aqueous genuine stain having a viscosity of 1 to 100 CPS (25 ° C.) containing a near-infrared absorber, fats and oils, a dryer, petroleum-based oil, and a non-aqueous liquid medium and colored with a dye or pigment. Ink.

  According to the present invention, when a genuine note such as a banknote, a securities, a postage stamp, a revenue stamp, a ticket, a certificate with a winning deposit is taken by an unauthorized means by robbery or theft, the genuine note was bundled. However, it is possible to quickly and reliably contaminate genuine bills, and in the visual sense of human beings, and in machines such as automatic money changers, vending machines, automatic ticket gates, automatic number readers, etc. It is now possible to leave clear evidence on a genuine note for a long time that it is recognized as a genuine note taken. Then, the evidence can make it impossible to use the genuine note taken by fraud, and as a result, the criminal act itself can be prevented and suppressed.

  The details of the genuine paper stain ink of the present invention will be described. Oils include non-drying oils such as olive oil, coconut oil and castor oil, semi-drying oils such as soybean oil, rapeseed oil and sunflower oil, and dry oils such as walnut oil, linseed oil and paulownia oil. Both are good, but with regard to washing resistance, drying oil having an iodine value of 130 or more is good, and the initial washing resistance is greatly improved by using a dryer together. The addition amount of fats and oils in the ink is preferably 1 to 30%, more preferably 5 to 20%. If it is less than 1%, the washing resistance is inferior, and if it exceeds 30%, the viscosity increases and the permeability decreases. There are two types of dryers used in combination with drying oils, an oxidation type and a polymerization type, both of which have an oxidation promoting effect, but the polymerization type is uniformly dried to the inside of the film and has good washing resistance. The addition amount of the dryer is preferably 5 to 20% of the drying oil, and if it is less than 5%, a sufficient acid value effect cannot be obtained. Detergency cannot be demonstrated. Examples of the oxidation type dryer include cobalt compounds such as cobalt octylate, cobalt linolenate, and cobalt resinate, and manganese compounds such as manganese octylate, manganese borate, manganese linolenate, and manganese resinate. Examples of the polymerization dryer include lead compounds such as lead octylate, zinc compounds such as zinc octylate and zinc naphthenate, calcium compounds such as calcium octylate and calcium naphthenate, and the like.

  Examples of the near-infrared absorber include polymethine, diimonium, aminium, cyanine, naphthalocyanine, anthraquinone, pyrazinocyanine, azonaphthol, and metal complex compounds, cyanine, phthalocyanine, Naphthalocyanine series is preferred. The added amount is preferably 0.1 to 10%, more preferably 1 to 5%. If it is less than 0.1%, a sufficient near-infrared absorption effect cannot be obtained, and if it exceeds 10%, the ink viscosity increases and the permeability is poor. Further, the maximum absorption wavelength of the near infrared absorber is preferably 750 to 1500 nm.

Petroleum oils include naphthenic (aliphatic), paraffinic (alicyclic), and aromatic oils, but aromatics are carcinogenic, and paraffinic oils are fluid at low temperatures. Since it is inferior, it is desirable to use a naphthenic petroleum oil. Preferably 1 to 1000 mm ² / s for the kinematic viscosity of the petroleum oil, 1 to 100 mm ² / sec is more preferable. The added amount is preferably 5 to 60%, more preferably 10 to 40%. If it is less than 5%, the permeability is insufficient, and if it exceeds 60%, the washing resistance is poor.

  It is effective for the genuine stain ink of the present invention to improve the permeability by adding a non-aqueous solvent to lower the viscosity. Solvents that can be used are not particularly flammable and preferably have a flash point of 70 ° C. or higher. If the genuine stain ink is extremely easy to dry, the genuine stain ink will be dried after adhering to the genuine note and before reaching the magnetic printing layer for authenticity identification. It is difficult to identify. Further, the non-aqueous liquid medium is preferably a hydrocarbon-based liquid medium, preferably mainly composed of aliphatic hydrocarbons, and the aliphatic hydrocarbons may not form a ring. Saturated ones are also included. As such a non-aqueous liquid medium, n-nonane (flash point: 30 ° C., boiling point: 150.8 ° C.), n-decane (flash point: 46.1 ° C., boiling point: 174.1 ° C.), n-dodecane (flash point: 73.9 ° C, boiling point: 216.3 ° C), decalin (flash point: 57.8 ° C, boiling point: 195.7 ° C), bicyclohexyl (flash point: 73.9 ° C, boiling point: 217-219 ° C (trans-trans), boiling point: 233-238 ° C (cis-cis)) and the like, and kerosene (flash point: 65 to 85 ° C, boiling point: 175 to 325 ° C) can also be exemplified.

  The viscosity of the ink for authentic stains of the present invention thus prepared is required to be 1 to 100 CPS at 25 ° C., and more preferably 10 to 100 CPS. When the viscosity exceeds 100 CPS (25 ° C.), the permeability decreases.

  A pigment or dye is added to the genuine stain staining ink of the present invention for visual and machine identification. The pigment that can be contained in the genuine stain ink preferably has a particle size of about 0.1 to 5 μm from the viewpoint of dispersion stability, and the dye that can be contained in the genuine stain ink is an acid. Those which are strong against alkali and not easily discolored are preferred.

  The genuine stain-contaminating ink of the present invention is contained in a genuine note storage device together with a member that bundles and stores genuine notes and a member that has a function of detecting an action of taking a genuine note by an unauthorized means, When the member detects the fraud, the genuine ink is discharged from the ink storage member toward the end face of the genuine paper bundle or the genuine paper is contained in the genuine contamination ink in the ink storage member. The end face of the bundle is thrown in and the genuine note is contaminated.

  The member for bundling genuine bills may be a member that accommodates genuine bills in a state where the long sides and short sides of the genuine bills are aligned and stacked, and does not have to be wrapped with a string, tape, bandage or the like. Further, the end face of the bundle of genuine notes may be accommodated so as to be vertically up or down in the vertical line direction, or may be accommodated so that the end face of the bundle of genuine notes is substantially vertical.

  “Acquisition of genuine bills by unfair means” here refers to an act of forcibly moving the genuine note storage device itself from a predetermined installation place by a person without a legitimate authority, ○ Opening the genuine note storage device Act, ○ Act of pulling out the genuine note receiving member from the genuine note receiving device, ○ Action of opening the genuine note containing member, ○ Act of pulling out the genuine note from the genuine note containing member, ○ Other similar acts.

In addition, the “member having a function of detecting an unauthorized deprivation” here refers to various sensors such as a mechanical switch, a vibration sensor, a capacitance change detection sensor, and a tilt detection sensor.

  As a member having a function of taking out genuine stain-contaminating ink from the ink containing member and contaminating the end face of the bundle of genuine bills when an illegal deprivation is detected, the containing member is simply destroyed and the ink is genuine. You may have a function only to be able to adhere to the end surface of a bundle. In addition, the top member of the genuine note storage member that accommodates one surface of the end face of the bundle of genuine note upwards in the vertical line direction and the bottom member of the ink storage member are common above the true note storage member. It may have a mechanism for destroying or pulling out a wall that forms a boundary between both members when an ink containing member is installed and an illegal deprivation action is detected. Or the member which has a function which injects the ink in the said accommodating member toward the end surface of the bundle | flux of the genuine note in the genuine note accommodating member or the genuine note being extracted from the genuine note accommodating member may be sufficient.

  As a member having a function of putting the end face of a genuine bundle into the contamination ink in the ink containing member and detecting the end face of the genuine bundle when an illegal deprivation is detected, for example, An ink containing member is installed below the genuine note containing member so that the bottom member of the genuine note containing member that accommodates one surface of the end face of the bundle is downward in the vertical direction and the ceiling member of the ink containing member are made common. However, it may have a mechanism that destroys or pulls out the wall that forms the boundary between the two members when an illegal deprivation action is detected.

  The mechanism / means for taking out the genuine stain ink from the ink containing member is not particularly limited as long as it can accurately contaminate the end face of the bundle of genuine bills, and various mechanisms / means can be selected. In addition, the genuine note may be contaminated by dripping, jetting, etc. the contamination ink onto the end face of the bundle of the genuine note in the stacked state, or the genuine note stored in the stacked or arranged state. The genuine note may be contaminated by putting the end face of the bundle into a member containing the staining ink.
