Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to securities and lottery tickets which are provided with a hologram image and which are extremely difficult to counterfeit and falsify to prevent fraudulent acts and enhance the security of individual information. In particular, the present invention relates to securities and lottery tickets capable of forming individual information by hologram.

[0002]

2. Description of the Related Art Conventionally, for securities such as stock certificates, gift certificates, checks, bills, entrance tickets, tickets, etc., serial numbers are provided as individual information different for each securities, and lottery tickets are A lottery number or lottery mark is provided as individual information different for each lottery ticket. The lottery mark is concealed by a peeling layer having a concealing function, and is used in a scratch lottery for peeling off and confirming the lottery mark.

These individual information are usually serial numbers,
Printed by a rotary type printing device called convex numbering unit, or in the case of random print information,
It is printed using a laser printer, a dot impact printer, an inkjet printer, or the like.

Under these individual information, usually, in order not to be tampered with by peeling off a part of the information,
We perform complicated fine prints with luminescent ink and solvent-reactive special ink, and use special ink as the ink for individual information.

However, in recent years, forgery and tampering techniques have become more sophisticated, and these forgery prevention techniques are no longer sufficient. In addition, as a means to make counterfeiting difficult, a hologram that is extremely difficult to counterfeit and falsify itself is attached to securities with a seal or a transfer foil, which makes it easy to visually confirm the authenticity. ing. In particular, recently, there has been a particularly strong demand for the emergence of means for making such forgery and tampering sufficiently difficult and preventing fraudulent activity.

[0006]

However, the conventional hologram has the same picture, characters, design, etc. formed thereon, and it is difficult to form different information one by one in the manufacturing process. It is impossible for conventional securities and lottery tickets to simply form individual information by hologram.

The present invention has been made in order to solve the above problems, and prevents fraudulent acts by making forgery and tampering extremely difficult, and at the same time provides individual information formed by hologram images. The purpose is to provide highly secure securities and lottery tickets.

[0008]

In order to achieve the above object, first, in the invention according to claim 1, a roll-shaped film in which a Lippmann hologram is prepared on a roll-shaped photopolymerization photopolymer and a diffusing agent is applied. The hologram produced by closely adhering to the photopolymerization photopolymer and heating, and changing the reproduction wavelength by changing the interval of the interference fringes recorded on the photopolymerization photopolymer, In securities that are pasted on the entire surface, as the hologram, the roll-shaped film coated with the diffusing agent is exposed to ultraviolet light before or after being adhered to the photopolymerization photopolymer. By generating a pattern with different reproduction wavelengths, individual information such as serial numbers, characters, and figures can be changed. And a hologram formed by continuously recorded.

According to the second aspect of the invention, a Lippmann hologram is produced on a roll-shaped photopolymerized photopolymer, and a roll-shaped film coated with a diffusing agent is brought into close contact with the photopolymerized photopolymer to heat the photopolymerized photopolymer. A hologram produced by changing the reproduction wavelength by changing the interval of the interference fringes recorded on the photopolymer is attached to a part or the whole surface of the lottery ticket body. Before or after adhering the roll-shaped film coated with the agent to the photopolymerization photopolymer, or after adhering, the roll-shaped film coated with the diffusing agent is subjected to ultraviolet light exposure to generate a pattern having a different reproduction wavelength, thereby performing a lottery. It has a hologram in which different individual information such as numbers and lottery marks are recorded continuously.

[0010]

Therefore, in the securities and the lottery ticket of the present invention, different information can be incorporated in each hologram by continuously recording different individual information in the hologram production process.

Further, by combining the hologram image pattern with the individual information pattern having a reproduction wavelength different from that of the hologram, it is difficult to forge the hologram, and even if the hologram is cut and pasted, it is easy to see after the cutting, so that the tampering prevention effect is extremely high. Will be things.

For example, if a lottery ticket of a certain type is released and then another lottery ticket is released and the winning number of the lottery ticket is cut and pasted, a clear cut line can be seen and tampered with. What you have done is obvious.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a cross-sectional view showing a configuration example when the present invention is applied to a lottery ticket, and FIG. 2 is a front view showing a configuration example when the present invention is applied to a lottery ticket.

In FIGS. 1 and 2, a desired pattern (TP) 22 is provided by printing on a part of the surface of the base material 21. Further, a Lippmann hologram 23 is attached to the illustrated portion other than the pattern 22 on the surface of the base material 21.

Furthermore, this Lippmann hologram 23
On the surface of the substrate 21, a first adhesive layer 231, a hologram layer 232 in which a photopolymerization photopolymer described later and a diffusing agent are integrated, a second adhesive layer 233, and a protective sheet 234 are sequentially formed. It is laminated.

A bar code 235 having a reproduction wavelength different from that of the surrounding hologram image pattern is provided on a part of the Lippmann hologram 23. Next, the production of the Lippmann hologram 23 (hologram layer 232) is as follows.
It is realized by the following method.

That is, first, a roll-shaped photopolymerization photopolymer (HRF) is subjected to duplicate exposure of a Lippmann hologram. Examples of this photopolymerized photopolymer include:
For example, "JP-A-2-3081" or "JP-A-2-3081".
No. 3082 ”is used. As a duplication method, for example,“ Japanese Patent Laid-Open No. 3-4292 ”is used.
The method of duplication using a rotating drum described in No.

Next, a film (CTF) coated with a diffusing agent described in, for example, "Japanese Patent Laid-Open No. 3-46687" is used in order to shift the reproduction wavelength with respect to the photopolymer subjected to duplication exposure.

Here, the diffusing agent is a substance similar to the monomer used in the photopolymerization photopolymer, and the interference fringes are formed by heating the photopolymerization photopolymer recording the interference fringes in close contact with each other. The diffusing agent acts to expand the gap, causing a shift in the reproduction wavelength. At this time, in order to prevent the subsequent diffusion when the desired wavelength is obtained, by irradiating ultraviolet rays and polymerizing the monomer,
The shift of the reproduction wavelength can be fixed.

By the way, before adhering the film coated with the diffusing agent to the photopolymerization photopolymer, or before heating after adhering, a certain amount of exposure of ultraviolet rays is irradiated to polymerize a certain amount of the monomer, By controlling the amount of the monomer involved in the shift of the reproduction wavelength, it is possible to obtain a desired shift of the reproduction wavelength.

That is, by exposing the film coated with the above-mentioned diffusing agent with ultraviolet rays having an appropriate exposure amount of an appropriate shape, an arbitrary shape is recorded at a reproduction wavelength different from the hologram image pattern around it. You can

FIG. 3 shows an apparatus for producing a Lippmann hologram according to this embodiment. Here, an example of the entire configuration of an apparatus that performs ultraviolet exposure on a film coated with a diffusing agent before the photopolymerized photopolymer subjected to duplicate exposure and a film coated with a diffusing agent are bonded together is shown.

That is, as shown in FIG. 3, the photopolymerized photopolymer 1 subjected to the duplicate exposure is peeled off from the HRF feeding roll 2 via the idler 4 by the splitter 6 while the cover film 3 is peeled off by the HRF cover film winding roll. It is wound up at 5 and sent to the nip roll 7.

The roll-shaped film (CTF) 8 coated with a diffusing agent is peeled off from the CTF delivery roll 9 via the idler 11 by the splitter 13 while the CTF cover film winding roll 1 is peeled off.
It is wound up at 2 and sent to the nip roll 7.

Then, the photopolymerized photopolymer 1 from which the cover film 3 has been peeled off by the nip roll 7,
The roll-shaped film 8 from which the cover film 10 has been peeled off is stuck and adhered.

Here, a positioning mark is recorded in advance on the portion of the photopolymerizable photopolymer 1 where the information of the image is recorded, and the mark is reproduced by the positioning mark illumination lamp 14 and read by the positioning mark reading sensor 15. To do so.

At this timing, an ultraviolet lamp 16 which is an ultraviolet ray generation source, a lens 17 which is an optical element, a liquid crystal shutter 18 which is a spatial modulation element,
An ultraviolet exposure device including an imaging lens 19 as an imaging element exposes the roll-shaped film 8 on the splitter 13 to ultraviolet light.

That is, from the positioning mark reading sensor 15, the photopolymerized photopolymer 1 is fed by the nip roll 7.
The length up to the portion where the roll-shaped film 8 and the roll-shaped film 8 are bonded together is
It is necessary to make the length equal to the position where the photopolymerized photopolymer 1 and the roll-shaped film 8 are pasted together by the nip roll 7.

FIG. 4 is a schematic diagram showing an example of the structure of the ultraviolet exposure apparatus. That is, in FIG. 4, first, the ultraviolet light emitted from the ultraviolet lamp 16 is collimated onto the liquid crystal shutter 18 by the lens 17, and the ultraviolet light transmitted by opening and closing the liquid crystal shutter 18 is transmitted by the imaging lens 19. A slit-shaped image is formed on the roll-shaped film 8 on the splitter 13.

In this case, the information projected on the liquid crystal shutter 18 is obtained by cutting the pattern to be recorded in a direction perpendicular to the feeding direction of the roll-shaped film 8 and decomposing it into a plurality of linear information. While synchronizing with speed,
This information is sequentially sent to the liquid crystal shutter 18.

That is, the individual information such as numbers and patterns,
Alternatively, a lottery number consisting of a bar code, a carla code, or a lottery mark is cut in a direction perpendicular to the feed direction of the roll-shaped film 8 to decompose it into a plurality of linear information, and the feed speed of the roll-shaped film 8 is obtained. While synchronizing
This information is sequentially sent to the liquid crystal shutter 18.

Although FIG. 4 shows the case where the lottery number is a bar code, the number and the hologram may overlap. Further, here, by setting the shape of the opening of the liquid crystal shutter 18 to be a shape that is enlarged in the feeding direction of the roll-shaped film 8, it is possible to set the enlargement ratio to the exposure amount of ultraviolet rays. That is, this is because the area of the liquid crystal shutter 18 in the feed direction of the roll-shaped film 8 serves as the opening of the imaging lens 19 and plays the role of the diaphragm of the imaging lens 19.

As described above, different UV exposure amounts can be given depending on the enlargement ratio of the roll-shaped film 8 in the feeding direction, and the reproduction wavelength can be freely controlled.

As described above, the roll-shaped film 8 and the photopolymerized photopolymer 1 which were exposed to ultraviolet rays were wound on the take-up roll 20 at the same time as the bonding, and heating was performed to match the ultraviolet exposure amount. A wavelength shift occurs, and there is a difference between the reproduction wavelength of the portion exposed to ultraviolet light and the reproduction wavelength of the unexposed portion.

Further, the same effect can be obtained when the film is exposed to ultraviolet rays after being laminated and then wound on a winding roll 20 and heated. As a result, it is possible to continuously record different individual information (in this example, a lottery number or lottery mark) such as a serial number, characters, and figures as a certain pattern.

In the above, the winding 20 of FIG.
On the other hand, the cover sheet on the CTF side is peeled off in a separate process (not shown), and an adhesive (pressure-sensitive adhesive) or an adhesive (dry pressure-sensitive adhesive, rewet pressure-sensitive adhesive, wet Emulsion type adhesive, Wet solvent type adhesive)
Is provided with an adhesive layer, and a release sheet (having a releasable resin such as a silicone resin applied to the attaching surface side) is releasably attached to the surface of the adhesive layer. . Then, the portion of the Lippmann hologram with individual information on this roll is half-blanked with a blanking die to make it easier to peel off than the release sheet, and is attached to a part of the surface of the base material 21 of the lottery ticket. Get a lottery ticket.

In the present embodiment, the base sheet (not shown) of the photopolymerization photopolymer 1 is present on the surface of the hologram 23, but the base sheet is peeled off and the pressure-sensitive adhesive layer 233 is provided again in consideration of durability. The protective sheet 234 having the is attached.

A black sheet may be provided on the lower surface of the hologram 23 to make the hologram image easy to see. This is for making the hologram image clearly visible by making the background blackish (so-called “backing”).

As this forming method, for example, there is a method of stacking sheets. That is, HRF after hologram recording (first cover film / photopolymer / second
Of the CTF (third cover film / diffusing agent / fourth cover film) after UV irradiation, and similarly, Are stacked (first
Cover film / photopolymer / diffusing agent / fourth cover film).

In this case, the first choice of cover film is
And any of the second, third and fourth can be arbitrarily selected, and the above is one example. Then, one of the cover films (first cover film / photopolymer / diffusing agent / fourth cover film) is peeled off, and
Cover film / adhesive / black sheet / adhesive /
The sixth cover film) is peeled off and adhered to either side of the photopolymer and the diffusing agent. The adhesive on the other side of the black sheet is used for adhesion to securities. Further, a protective layer can be similarly laminated on the portion facing the outside if necessary.

In the above, the lamination is performed by the adhesion method, but the adhesion of the black sheet, the bond to the securities, the adhesion of the protective layer, etc. may be performed by the lamination method. Next, in the lottery ticket constructed by sticking the Lippmann hologram 23 produced as described above on the surface of the base material 21, the recording of different individual information (lottery number or lottery mark) is changed. Hologram 23
Since it is done continuously during the manufacturing process of
Different information (lottery number or lottery mark) can be included in each Lippmann hologram 23. Thereby, a lottery ticket in which different individual information is individually recorded can be obtained.

Further, since the hologram image pattern and the individual information recording patterns having different reproduction wavelengths are combined, it is difficult to forge the Lippmann hologram 23, and even if it is cut and pasted, it is easy to see after the cutting, so that tampering is prevented. The effect is extremely high.

For example, if a lottery ticket of a certain type is released and then another lottery ticket is released and the winning number is cut and pasted to the number of the previous lottery ticket, a clear cut line is seen and falsification is performed. What you have done is obvious.

As described above, in the lottery ticket of this embodiment, since the Lippmann hologram 23 in which different individual information (lottery number or lottery mark) is recorded is attached to the lottery ticket main body, the hologram image pattern and the individual information. Since the reproduction wavelength of the pattern is different, the effect of preventing forgery is high, and the effect of preventing falsification such as cutting and pasting is also extremely high.

As described above, in this embodiment, the Lippmann hologram 23 is formed on the roll-shaped photopolymerized photopolymer 1.
And the roll-shaped film 8 coated with a diffusing agent is brought into close contact with the photopolymerization photopolymer 1 and heated to change the interval of interference fringes recorded on the photopolymerization photopolymer 1 to shift the reproduction wavelength. In the lottery ticket in which the Lippmann hologram 23 produced by the above is attached to a part of the base material 21 of the lottery ticket main body, the ultraviolet light exposure including the ultraviolet lamp 16, the lens 17, the liquid crystal shutter 18, and the imaging lens 19 is performed. Before the roll-shaped film 8 coated with the diffusing agent is adhered to the photopolymerization photopolymer 1 as the Lippmann hologram 23, the roll-shaped film 8 coated with the diffusing agent is exposed to ultraviolet rays to obtain a reproduction wavelength. By generating different patterns, different individual information (lottery number or lottery mark) can be recorded continuously. Become one in which was to comprise a Lippmann hologram.

Therefore, different individual information (lottery number,
Alternatively, since the lottery mark) is continuously recorded in the manufacturing process of the Lippmann hologram 23, different information (lottery number or lottery mark) can be included in each Lippmann hologram 23. . This makes it possible to obtain a lottery ticket in which different individual information is individually recorded.

Further, since the hologram image pattern and the individual information pattern having a different reproduction wavelength are combined, duplication becomes difficult, so that an anti-counterfeiting effect can be expected, and even if cut and pasted, it is easy after cutting. Therefore, it is possible to obtain a product having an extremely high tampering prevention effect.

As described above, in the lottery ticket of this embodiment, since the Lippmann hologram 23, which records different individual information (lottery number or lottery mark), is attached to the lottery ticket body, it is combined with the hologram image. Since the reproduction wavelength is different from the surroundings, the anti-counterfeiting effect is high,
The effect of preventing falsification such as cutting and pasting is also extremely high.
