DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety filament buried in a paper layer of a paper, in which a coercive force is initially set to be low, and becomes extremely high once exposed to a magnetic field. And a safety filament provided with a magnetic layer containing a ferromagnetic material. Further, the present invention relates to a safety filament buried in a paper layer of a paper, in which a coercive force is initially set to be low, and exhibits a characteristic that the coercive force becomes extremely high once exposed to a magnetic field. And a safety layer provided with a functional layer provided with a functional material exhibiting predetermined optical characteristics by emitting light upon irradiation with a light beam of a predetermined wavelength. The present invention also relates to anti-counterfeit paper in which such a security line is buried in a paper layer, and banknotes, securities, and certificates having a monetary value using such anti-counterfeit paper as a base material. And valuable printed matter including documents proving rights, qualifications, and ID information. The present invention also relates to an authenticity discriminating apparatus for authenticating such anti-counterfeit paper and valuable printed matter.

2. Description of the Related Art When manufacturing valuable printed materials including paper money, securities, papers having financial value and documents proving rights, qualifications, and ID information, the purpose of the present invention is to prevent forgery of the valuable printed materials. Forgery-prevention paper in which a safety filament is embedded in a paper layer has been used as a base material. As such a forgery prevention paper, for example, Japanese Patent Application Laid-Open No. Sho 61-152494 discloses a forgery prevention paper in which a safety line containing both a magnetic material and a fluorescent material is embedded in a paper layer. A security paper is disclosed in which a safety filament in which a synthetic resin layer containing a synthetic resin layer and a synthetic resin layer containing a fluorescent material are laminated using a common extrusion molding technique in plastic processing is embedded in a paper layer.
For valuable printed matter using such anti-counterfeit paper as a base material, the absorptivity and excitation emission wavelength when irradiating a light beam with a predetermined wavelength such as ultraviolet light or infrared light to the safety line can be detected. In many cases, the authenticity is determined by detecting an absorption rate or an induced voltage when the strip is irradiated with an electromagnetic wave.

[0003] Further, in foreign bills in which a security line is buried in a paper layer, for the purpose of discriminating the banknote type when authenticating the banknote, the security line is used for each banknote type. The portion where the magnetic material is provided is changed. In this case, in order to make the presence of the magnetic information recorded on the safety streaks seemingly invisible under normal conditions, white ink or the like is printed on both front and back surfaces of the banknote, so that the safety streaks are printed. It has been practiced to hide the presence of the provided colored magnetic material from the front and back surfaces of the bill. Furthermore, with anti-counterfeit paper in which safety lines made by printing characters and other patterns on a transparent film with black ink are embedded in the base paper, the patterns can be seen even by ordinary observation. There is a drawback that a similar appearance can be easily obtained even when a pattern such as a character is printed. Therefore, JP
JP-96491 discloses an anti-counterfeit paper in which a safety filament having a pattern printed with a highly concealable white ink on a transparent support film is embedded in a pulp base paper. With this anti-counterfeit paper, it was difficult to determine where the safety streaks were made by simply observing from the front, and it was printed on the safety streaks only when observed under transmitted light. Since a design such as a character can be recognized, it has been difficult to forge simply by printing a design such as a character on a sheet of paper with gray ink or the like.

[0004] Also, JP-A-7-32778 and JP-A-7-2
JP-A-66769 and JP-A-8-127997 have disclosed a safety protection paper in which a safety filament having a magnetic layer made of a ferromagnetic amorphous material is embedded in a paper layer. Here, the magnetic layer is subjected to processing such as laser beam irradiation, microwave irradiation, heating, pressurization, cutting, and cutting, and the magnetic permeability, saturation magnetization characteristics, magnetostriction characteristics, and the like of the ferromagnetic amorphous material forming the magnetic layer. Is partially changed to record fixed or semi-fixed magnetic information on the magnetic layer. In this case, after the ferromagnetic amorphous material constituting the magnetic layer is magnetically excited using an excitation coil, the fixed or semi-fixed magnetic information recorded on the magnetic layer is read using a normal magnetic head. The security paper was judged. Japanese Patent Application Laid-Open No. Hei 7-279098 discloses that, using a magnetic head, magnetic information excited using an exciting coil is read using a magnetic head, and then magnetic information in a magnetically excited state is confidential. There has been disclosed a device for judging the authenticity of safety protection paper which is degaussed again using a degaussing head for holding.

Further, Japanese Patent Application Laid-Open Nos. 8-138921 and 9-138921
JP-A-102117 and JP-A-10-269556 disclose a magnetic powder mainly composed of MnBi, which exhibits a characteristic that the coercive force is remarkably increased when magnetic information is recorded by exposing it to a magnetic field. At the same time, these publications describe a magnetic layer composed of a magnetic powder mainly composed of MnBi, and at least one magnetic powder selected from oxide magnetic powder, metal magnetic powder, alloy magnetic powder and compound magnetic powder. A magnetic recording medium provided with a magnetic layer obtained by laminating a constituted magnetic layer, or a magnetic powder mainly composed of MnBi, an oxide magnetic powder, a metal magnetic powder, an alloy magnetic powder, and a compound magnetic powder. Also disclosed is a magnetic recording medium provided with a magnetic layer containing at least one magnetic powder. Further, these publications are a method and a device for recording and reproducing magnetic information on these magnetic recording media, and record and reproduce magnetic information that becomes extremely difficult to rewrite once recorded using a normal magnetic head. A recording / reproducing method and a recording / reproducing apparatus capable of performing the same have been disclosed.

Japanese Patent Application Laid-Open No. 12-82208 discloses a magnetic material which has a coercive force at room temperature of 10 KOe or more and whose initial magnetization curve from a demagnetized state at room temperature saturates at a magnetic field of less than half the coercive force. A magnetic layer is formed on the recording layer using a high-permeability magnetic material having a coercive force of 30 Oe or less, and a magnetic pattern written on the recording layer is formed by a magnetic head. A magnetic barcode which can be additionally written using a magnetic head but cannot be rewritten using a magnetic head once and has been exposed to a magnetic field, and a recording method thereof have been disclosed. Here, as a magnetic material that can be used when forming the recording layer, when it is in a demagnetized state, it has the property of being saturated with a magnetic field of 5KOe or less that can be written using a magnetic head, and has the property of normal permalloy or Writable with a Sendust magnetic head, but once magnetized, the coercive force
An intermetallic compound magnetic material such as MnBi, which has a characteristic in which the magnetization direction is not changed even when an external magnetic field is applied by a magnetic head after that becomes 10 KOe or more, is exemplified.

[0007]

However, in a conventionally widely known anti-counterfeiting paper in which a safety filament containing a magnetic material is embedded in a paper layer, a magnetic material having general magnetic properties as a magnetic material is used. Because the safety wire was configured using the safety wire, a magnetic field larger than the coercive force of the magnetic material included in the safety wire may be applied to the safety wire during the distribution of the forgery prevention paper. Permanently determine whether the anti-counterfeit paper is authentic based on the magnetic information recorded on the safety filament because the magnetic information recorded on the security filament is easily falsified due to the magnetic properties of the material. Was difficult.

On the other hand, in a forgery prevention paper in which a safety filament manufactured by a co-extrusion molding technique disclosed in Japanese Patent Application Laid-Open No. Sho 61-152494 is embedded in a paper layer, the safety filament is made of a magnetic material and a fluorescent material. Since both materials were mixed with a synthetic resin, the functions of both the magnetic material and the fluorescent material could not be sufficiently extracted from the surface of the forgery prevention paper. At this time, for the fluorescent material, if a window for exposing a part of the security line is provided on the surface of the forgery prevention paper, the fluorescent light is emitted from the surface of the forgery prevention paper at a position corresponding to the window. However, it was not possible to confirm sufficient fluorescence emission from the surface of the forgery prevention paper at the place where the safety filament containing the fluorescent material was embedded in the paper layer. Furthermore, in a magnetic material having general magnetic properties, if the orientation state of the crystal of the magnetic material called magnetic anisotropy can be aligned in a predetermined direction, the magnetic strength can be set high, JP 61
When manufacturing a safety filament by a co-extrusion molding technique as disclosed in Japanese Patent No. 152494, since the magnetic filament was mixed with a synthetic resin to constitute the safety filament, the crystal orientation of the magnetic material was In addition, sufficient magnetic strength could not be stably obtained from the surface of the anti-counterfeit paper with the above arrangement.

[0009] Further, in a foreign banknote in which magnetic information is recorded by changing the position where the magnetic material is provided in the safety filament buried in the paper layer, the confidentiality of the magnetic information recorded in the banknote is reduced. In order to improve the security line, various measures are required to prevent the position where the colored magnetic material is provided in the safety filament from being grasped in a normal state, and it takes much time to manufacture a bill. , Labor and cost have been required. Further, the anti-counterfeit paper disclosed in Japanese Patent Application Laid-Open No. 12-96491 records invisible magnetic information in a normal state using a colored magnetic material on a safety line embedded in a paper layer of the paper. It was not applicable when you did.

The permeability, saturation magnetization, magnetostriction, etc. of the ferromagnetic amorphous material must be partially changed, which makes it special and complicated compared to the case where magnetic information can be easily recorded using a general magnetic head. A recording method was needed. Furthermore, with these safety protection papers, when magnetic information recorded on the safety filament is read using a general magnetic head, the safety filament is energized externally by a static magnetic field or an AC magnetic field. After a magnetic field change occurs in the area where information is recorded, magnetically excited information must be read, and magnetic information can be easily read using a general magnetic head. In comparison, a special and complicated reading method was required.

As disclosed in Japanese Patent Application Laid-Open No. 12-82208, it is possible to increase the information by additionally writing a magnetic pattern to be written on the recording layer. The magnetic bar code that makes it impossible to rewrite the magnetic information using a magnetic head is printed on the surface of the base material constituting the credit card, prepaid card, commuter pass, etc. Because it is provided, or to provide a concealing layer to make the presence of the magnetic barcode invisible in a normal state,
In order to provide resistance to friction, abrasion and scratching during distribution, a protective layer must be provided. For this reason, a lot of time, labor, and cost have been required when manufacturing a credit card, a prepaid card, a commuter pass, etc. provided with a magnetic barcode in a mode suitable for actual use.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view showing a safety line, a forgery prevention sheet, a valuable printed matter and a device for judging the authenticity thereof according to the present invention.

The safety filament according to the present invention includes a security filament capable of recording only magnetic information, a security filament capable of recording optical information only on one side together with magnetic information, and an optical information filament on both sides together with magnetic information. Can be recorded into three types of safety filaments. These safety filaments were formed on a support film composed of a polymer material such as polyethylene terephthalate, polyethylene naphthalate or aramid as a base material layer, and each layer was formed as shown in FIG. 2 to FIG. The slit-shaped sheet-like material was slit into a long strip using a slitter,
As shown in FIG. 1 (a), the paper is wound on a bobbin, fed onto a fourdrinier paper machine or a round paper machine, and buried in a paper layer of anti-counterfeit paper. The hatched portion in FIG. 1B shows a cross section obtained when the safety filament according to the present invention is cut perpendicularly to the longitudinal direction. As shown in FIG. 2 to FIG. Are laminated. At this time, as disclosed in Japanese Patent Application Laid-Open No. 12-96491, the safety filament according to the present invention embeds the safety filament in the paper layer of the forgery prevention paper, when manufacturing the security filament. In consideration of the workability when performing, anti-counterfeiting effect on anti-counterfeit paper, suitability for machine processing, etc.
It is preferable to have a width of about 5 mm, especially about 1.5 mm, and a thickness of 10 to 35 μm. Further, the magnetic information and optical information recorded on the safety filament according to the present invention can be obtained by slitting a sheet-like material in which each layer is laminated to a predetermined width as shown in any of FIGS. It is recorded on the sheet before slitting in the direction of slitting the sheet so that the safety line in which magnetic information and optical information are recorded in the direction can be obtained. .

FIG. 2 shows a safety filament according to the present invention.
FIG. 3 shows a cross-sectional view obtained when a safety filament capable of recording only magnetic information is cut perpendicular to the longitudinal direction. In this case, a base material layer and a magnetic layer containing a ferromagnetic material having a characteristic that the coercive force is initially set to be low and becomes extremely high once exposed to a magnetic field are laminated in the thickness direction. Thus, the safety filament according to the present invention is configured. In this safety line, magnetic information can be recorded by applying a magnetic field to a part of a magnetic layer containing a ferromagnetic material that exhibits a characteristic that the coercive force increases significantly once exposed to a magnetic field. In this state, the presence of the magnetic information cannot be visually recognized, and the magnetic information that is extremely difficult to tamper can be recorded and reproduced using a general magnetic head. In other words, in this safety filament, once exposed to a magnetic field, predetermined magnetic information is recorded with a remarkably high coercive force, so that once the predetermined magnetic information is recorded, an external magnetic field is applied. It becomes extremely difficult to rewrite with new magnetic information after demagnetization. At this time, the magnetic layer constituting the safety filament according to the present invention includes a ferromagnetic material that exhibits a characteristic that the coercive force becomes extremely high once exposed to a magnetic field, an oxide magnetic powder having a relatively small coercive force, and a metal. At least one magnetic material selected from magnetic powders, alloy magnetic powders, and compound magnetic powders or a magnetic material having high magnetic permeability may be contained. That is, in order to be able to record magnetic information that is extremely difficult to be tampered with in the safety filament according to the present invention, once the magnetic layer constituting the safety filament is exposed to a magnetic field, the coercive force is significantly increased. What is necessary is that a ferromagnetic material showing the following is contained. In addition, in this safety filament, a magnetic layer containing a ferromagnetic material with extremely little deterioration of saturation magnetization can be laminated to form the safety filament, so that the magnetic properties of the magnetic material contained in the safety filament can be improved. Can be sufficiently extracted.

FIG. 3 (a) shows a safety filament according to the present invention, which can record optical information on only one side together with magnetic information when the security filament is cut perpendicularly to the longitudinal direction. The resulting cross-sectional view is shown. In this case, the base material layer, a magnetic layer containing a ferromagnetic material whose coercive force is initially set to be low and becomes extremely high once exposed to a magnetic field, and a light beam having a predetermined wavelength are reflected. Reflective layer, and an optical functional layer provided with a functional material that emits light when irradiated with the light of the predetermined wavelength and exhibits predetermined optical characteristics, the base layer, the magnetic layer, the reflective layer, The safety filament according to the present invention is configured by being laminated in the thickness direction in the order of the optical functional layers. In this safety line, the same action and effect as the safety line shown in FIG. 2 can be obtained with respect to the magnetic layer and the magnetic information, and a reflective layer that reflects light of a predetermined wavelength that emits light from the functional material is laminated. As a result, the safety filament can be formed, so that the optical characteristics of the functional material contained in the safety filament can be sufficiently extracted. Furthermore, in this safety line, if optical information is recorded on the optical functional layer in such a manner that it is associated with magnetic information recorded on the magnetic layer, which is extremely difficult to be tampered with, the tampering of the optical information is performed. Even if you do, you can easily spot fraud. 3 (b) to 3 (e) show a safety filament according to the present invention, in which optical information can be recorded only on one side together with magnetic information. Although the cross-sectional view obtained when it is cut vertically is shown, these safety filaments can also exert the same operation and effect as the safety filament shown in FIG.

FIG. 4A shows a safety filament according to the present invention, which can be used for recording optical information on both sides together with magnetic information when the security filament is cut perpendicularly to the longitudinal direction. FIG. In this case, a first optical functional layer to which a first functional material having a first optical property is emitted when irradiated with a first wavelength light beam and reflects the first wavelength light beam is reflected. A first reflective layer, a base material layer, a magnetic layer containing a ferromagnetic material having a property that the coercive force is initially set to be low and that becomes extremely high once exposed to a magnetic field; A second reflective layer that reflects light having a second wavelength, and a second optical function provided with a second functional material that emits light when irradiated with the light having the second wavelength and exhibits a second optical property. Layer and the first optical functional layer, the first reflective layer, the base layer, the magnetic layer, the second reflective layer, the thickness direction in the order of the second optical functional layer To form a safety filament according to the present invention.
In this safety filament, the same action and effect as the safety filament shown in FIG. 2 can be obtained with respect to the magnetic layer and the magnetic information, and the light of the first wavelength that causes the first functional material to emit light is reflected. Since the first reflective layer and the second reflective layer that reflects the light of the second wavelength that causes the second functional material to emit light can be laminated to form a safety line, it is included in the safety line. The first optical property of the first functional material to be used and the second optical property of the second functional material included in the safety filament can be sufficiently extracted. Further, in the safety filament, the optical information is recorded on the magnetic layer and is difficult to be tampered with so as to be associated with the magnetic information. If optical information is recorded on the functional layer, even if the optical information is tampered with, it can be easily detected. 4 (b) to 4 (d) show a safety filament according to the present invention, in which a safety filament capable of recording optical information on both sides together with magnetic information is perpendicular to the longitudinal direction. FIG. 4 shows a cross-sectional view obtained when the cutting is performed. However, these safety filaments can also exert the same operation and effect as the safety filament shown in FIG.

In the safety filament shown in FIGS. 2 to 4, a sheet-like material having a ferromagnetic material mainly composed of MnBi coated on the entire surface is slit into a predetermined width in the longitudinal direction, so that the security is initially maintained. A magnetic layer containing a ferromagnetic material, which has a low magnetic force and exhibits a characteristic that the coercive force becomes extremely high once exposed to a magnetic field, can be laminated. Here, on the assumption that a sheet-like material coated with a ferromagnetic material mainly composed of MnBi on the entire surface is conveyed from upstream to downstream, a specific method for recording magnetic information on the magnetic layer Will be described.
In order to obtain a safety filament that is a long object that is continuous in the longitudinal direction by slitting a sheet-like object conveyed at a predetermined speed vmm from the upstream to the downstream at a predetermined speed vmm in the longitudinal direction and slitting it to a predetermined width. When doing, first, using a magnetic head fixed in advance to the position where the sheet-like material is to be slit in the longitudinal direction, a predetermined length in the longitudinal direction of the safety filament which is the direction of slitting the sheet-like material T from position P
An alternating magnetic field of a predetermined frequency fHz is applied to the magnetic layer for only seconds. Next, using a magnetic head fixed downstream of the magnetic head to which the AC magnetic field is applied, a predetermined DC magnetic field is continuously applied in the longitudinal direction of the safety wire. According to this recording method, the predetermined position P in the longitudinal direction of the safety filament is
A state in which f × t rectangular waves are continuously increased remarkably continuously for a distance of v × t mm in the longitudinal direction of the safety filament from
That is, recording can be performed in a state where it is extremely difficult to falsify. In this case, the number of rectangular waves continuously recorded in the longitudinal direction of the safety wire, the distance in which the rectangular waves are continuously recorded in the longitudinal direction of the safety wire, the length of the safety wire Various types of pattern information and the like recorded using the area where the rectangular wave is recorded in the direction and the area where the rectangular wave is not recorded can be used as the magnetic information. On the other hand, the sheet-like material conveyed at a predetermined speed vmm from the upstream to the downstream is slit to a predetermined width in the longitudinal direction to obtain a long and continuous safety filament in the longitudinal direction. When attempting to slit the sheet-like object in the longitudinal direction, using a magnetic head fixed in advance at the position where slitting is to be performed in the longitudinal direction, in the longitudinal direction of the safety filament that is the direction in which the sheet-like object is slit If an AC magnetic field having a predetermined frequency fHz is continuously applied to the magnetic layer, d × is continuously applied for a distance of dmm from an arbitrary position Q in the longitudinal direction of the safety filament toward the longitudinal direction of the safety filament. f / v rectangular waves can be recorded in a state where the coercive force is extremely high, that is, in a state where it is extremely difficult to falsify. In this case, the number of rectangular waves continuously recorded from an arbitrary position Q in the longitudinal direction of the safety wire to a distance of dmm in the longitudinal direction of the safety wire can be used as magnetic information.

In the safety striation shown in FIGS. 3 and 4, a material having a property of reflecting light of a predetermined wavelength is deposited on the entire surface.
The reflecting layer can be laminated by slitting the plated or coated sheet material to a predetermined width in the longitudinal direction. For example, a sheet material obtained by depositing a pure metal, an alloy or an oxide, which is a material having a property of reflecting a light beam of a predetermined wavelength, on the entire surface by vacuum deposition is slit into a predetermined width in the longitudinal direction and reflected. It is possible to laminate a layer or a sheet-like material coated on the entire surface with calcium carbonate having a property of reflecting light rays of almost all wavelengths by slitting a predetermined width in a longitudinal direction to laminate a reflective layer. it can. Also, using a co-extrusion molding technique, a sheet-like material containing a material having the property of reflecting light of a predetermined wavelength or calcium carbonate having a property of reflecting light of almost all wavelengths in a base material Can be slit into a predetermined width in the longitudinal direction to make the base material itself a reflective layer.

In the safety filament shown in FIGS. 3 and 4, a fluorescent substance that emits light having a wavelength in any of the visible region, the ultraviolet region, and the infrared region is moved in a direction corresponding to the longitudinal direction of the safety filament. The optically functional layer can be laminated by slitting a sheet-like material applied or printed in a predetermined width in a direction corresponding to the longitudinal direction of the safety filament.
In this case, the minute characters recorded using the fluorescent substance in the longitudinal direction of the safety line, the distance at which the fluorescent substance is continuously applied in the longitudinal direction of the safety line, the safety line The emission wavelength when the fluorescent substance applied to the substrate is excited and emitted, and recorded using the area where the fluorescent substance is applied and the area where the fluorescent substance is not applied in the longitudinal direction of the safety filament. Various types of pattern information and the like can be used as optical information. Substances that emit light having a wavelength in the visible region include, for example, zinc sulfide-based compounds, zinc oxide-based compounds, zinc silicate-based compounds, and substances that emit light having a wavelength in the ultraviolet region are, for example, BaSi ₂ O ₅ : Pb, SrB ₄ O ₇ : E
There are u, Ca ₃ (PO ₄ ) ₂ : Tl, etc., and substances that emit light having a wavelength in the infrared region are, for example, LiAlO ₂ : Fe, (ZnCd) S: Cu, YVO ₄ : Nd
Etc. As the fluorescent substance, a material that emits and emits light by light having a wavelength in any one of a visible region, an ultraviolet region, and an infrared region may be used, or a material that emits and emits heat by heat may be used. Good. Here, the optical information is normally recorded on the optical functional layer so as to show the same color tone as the color tone of the reflective layer, or if the optical information is normally recorded on the optical functional layer so as to show a transparent state. Recording optical information that is normally invisible at normal time on the optical functional layer, and then optically reading optical information that is invisible at normal time from the optical functional layer only under predetermined viewing conditions Becomes possible. At this time, since the optical information recorded on the security streak can be further concealed, forgery and falsification of the forgery prevention paper can be made more difficult.
