DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lottery ticket which is displayed by characters, numbers, patterns, etc. and determines a hit, a loss, and the like. I, even if tampered with,
The present invention relates to a lottery ticket provided with a counterfeiting prevention measure capable of easily distinguishing a genuine ticket from a falsified product.

[0002]

2. Description of the Related Art Conventionally, lottery tickets such as lottery tickets, entrance tickets, game tickets, and the like, which are hit by securities numbers, characters, patterns, and the like, to determine a loss have been put to practical use. For example, as shown in FIG. 4, a printing layer 18 is provided on the base material 19 by characters, numbers, patterns, and the like that indicate a loss, and a transparent release layer 12 and a printing layer are printed thereon so as to cover this printing layer. A lottery ticket provided with a concealing layer 11 by printing using an ink mixed with metal powder or the like so that the layer is not visible is known. A user of this lottery ticket has scrapped the concealing layer 11 and checks whether it is a winning ticket or a lost ticket based on the content of the printing layer 18, so-called scratch-off lottery has been put to practical use.

[0003] However, so-called forgery or falsification has occurred in which the printed layer of these numbers, characters, patterns, etc. is changed or modified to falsify the lost ticket into a winning ticket. For this reason, these securities have been subjected to forgery-prevention printing such as tint block and fine print, or forgery prevention by printing with special ink. However, the anti-counterfeiting effect and the ease of authenticity confirmation have not always been satisfactory.

Therefore, the applicants of the present application have made a metal foil as an intermediate layer, bonded papers on both sides thereof, applied desired printing on one side of the paper, and included a part of the printing containing a colored pigment and a fluorescent dye. A ticket printed with an ink and provided with an overcoat layer made of a transparent varnish on a printing section made of the ink containing the fluorescent dye, wherein the fluorescent dye is printed from the printing section in the thickness direction of the overcoat layer and the paper layer. In the range reaching the metal foil with, for example, even if the number is falsified, the fluorescent dye remains in the shape of the base number, so it can be tampered with by illuminating with the light beam for emission Can be easily determined, counterfeit prevention measures have been implemented
No. 907 has been disclosed and put to practical use.

[0005]

However, in the former case, effective countermeasures for preventing forgery and falsification are not sufficient, and in the latter case, a metal foil layer is provided in the base material layer. The production cost is high because it is a special paper and uses a special ink containing a fluorescent dye.
That is, when it is used for a normal lottery ticket or the like, it is difficult to adopt it in terms of manufacturing cost. Therefore, the present invention has been made in view of the above problems, and by using a concealing layer of a transfer foil and a transfer adhesive layer containing a fluorescent material or an infrared absorbing material, it is possible to prevent tampering with a winning ticket, and at a low manufacturing cost. It is an object of the present invention to provide a lottery ticket that can be manufactured and has a counterfeiting prevention measure that can easily determine a genuine ticket and a counterfeit ticket.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a method of printing characters, numbers, patterns, or the like, which indicate a hit or a loss on a predetermined position of a printing substrate made of paper or a resin sheet. A ticket that is concealed so as to cover the printing layer with a transfer foil having a concealing layer and a colorless and transparent transfer adhesive layer, wherein the colorless and transparent transfer adhesive layer includes a fluorescent material or an infrared ray. Provided is a lottery ticket provided with a counterfeit prevention measure characterized by being mixed with an absorbing material.

[0007] The transfer foil according to the first aspect of the present invention comprises a base material made of a resin film, a first release layer and a first adhesive layer interposed therebetween, a metal deposition layer, and further a second metal layer thereon.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention relates to a resin film which is provided at a predetermined position on a printing base material by a character, a numeral, a pattern, or the like which indicates a hit and a loss, and covers the printing layer. On top of this, a metal deposition layer via a first release layer and a first adhesive layer, and a transfer adhesive layer mixed with a fluorescent material or an infrared absorbing substance via a second adhesive layer and a second release layer are sequentially laminated. This is a lottery ticket hidden by the transferred transfer foil. Therefore, the user hits by peeling the metal deposition layer,
Without noticing the transfer adhesive layer containing a colorless and transparent fluorescent material or infrared absorbing material that covers the printing layer that determines the loss, characters,
You can check the number or pattern.

Further embodiments will be described with reference to the drawings.
FIG. 1 is a cross-sectional explanatory view of a transfer foil in an embodiment of the present invention (A) and a cross-sectional explanatory view of a printing base material provided with a printing layer (B).
It is. As shown in FIG. 1A, the transfer foil 10 of the present invention
Is a method in which a metal deposition layer 4 is laminated on a resin film 1 such as PET via a first release layer 2 and a first adhesive layer 3, and a second release layer 5 and a second release layer 5 are further formed on the vapor deposition layer. A layer 6 is laminated, and a colorless and transparent transfer adhesive layer 7 is sequentially laminated via the second release layer 6. The transfer adhesive layer 7 is mixed with a fluorescent material or an infrared absorbing material. FIG. 1 (B)
Is a printing substrate 9 made of a resin sheet such as paper, synthetic paper or PET or vinyl chloride, and provided with a printing layer 8 such as a number, a character, and a pattern for determining a hit or a loss. It is printed at a predetermined position.

Here, metal such as aluminum can be used for the metal vapor deposition layer 4 constituting the concealing layer of the transfer foil 10, and vapor deposition may be performed by a commonly used vapor deposition method such as vacuum vapor deposition. Further, if the vapor deposition layer has a thickness of 400 to 2000 °, it is sufficient as a concealing layer. Note that the present invention is not limited to the metal vapor-deposited layer, and it is also possible to use a metal foil having a hiding effect.

The colorless and transparent transfer adhesive layer 7 uses a transparent adhesive, and is made of acrylic, urethane, epoxy, or the like.
A polyester or vinyl simple substance or a mixture is used alone or in combination. The fluorescent material or infrared absorbing material to be mixed was a colorless and transparent organic or inorganic fluorescent pigment or dye or infrared absorbing material, which was dispersed or dissolved in a colorless and transparent adhesive (including a solvent) and mixed. Things.

FIG. 2 is an explanatory cross-sectional view of a lottery ticket to which forgery prevention measures have been applied in one embodiment of the present invention. As shown in FIG. 2, the transfer foil 10 is formed on the print layer 8 of the print base material 9.
Is transferred by a hot press or the like so as to cover the printing layer 8 with the transfer adhesive layer 7 of the above, so that the concealing layer and the colorless transparent fluorescent material or infrared absorbing material-containing transfer adhesive by the metal deposition layer 4 in one transfer. The layer 7 can be provided, and a lottery ticket with anti-counterfeiting measures can be obtained.

In the lottery ticket of the present invention, if the metal deposition layer 4 serving as the concealing layer is scraped off, the ticket is scraped off from between the second adhesive layer 5 and the second peeling layer 6, and the printing layer 8 is removed. Exposed. Therefore, the user of the winning ticket can visually recognize the printed layer 8 from which the loss can be determined by hitting through the colorless and transparent transfer adhesive layer 7.

Here, by mixing the fluorescent material in the transfer adhesive layer 7 in advance, the colorless and transparent transfer adhesive layer is not noticed in a normal state, and it is possible to determine a hit and a loss. However, if the falsified printed layer 8 is artificially falsified by, for example, replacing or scraping, the transfer adhesive layer 7 mixed with the fluorescent material is also shaved.
Irradiation with an ultraviolet (UV) lamp or the like disturbs the light emitting state of the transfer adhesive layer, so that it is possible to easily judge a tampered product.

Here, the fluorescent material is, for example, ZnO: Z
n (emission wavelength of 505 nm for excitation light having a wavelength of 365 nm or 254 nm), Zn ₂ GeO ₂ : Mn (emission wavelength of 534 nm), Zn ₂ SiO ₄ : Mn (emission wavelength of 5
_{25nm), Sr 5 (PO 4} ) 3 CI: Eu ( emission wavelength _{445nm), Y 2 O 2 S} : Eu ( emission wavelength 624n
m), 3 (Ba, Mg) 0.8 Al ₂ O ₉ : Eu, Mn
(Emission wavelength 514 nm), ZnS: Cu (emission wavelength 52
8 nm), ZnS: Mn (emission wavelength: 586 nm), 0.1.
A fluorescent substance such as 5MgF ₂ , 3.5MgO, GeO ₂ : Mn (emission wavelength: 655 nm) is used to form a particle having a particle size of 0.8 μm.
Fine particles of about m to 2.0 μm are used as fluorescent pigments, dispersed in a resin, and laminated by coating, printing, or the like. If the particle size is less than the above, the fluorescent brightness is deteriorated, and if the particle size is more than the above, the printability may be deteriorated or the fluorescent pigment may be peeled off after printing.

The material to be mixed with the transfer adhesive layer 7 is not only a fluorescent material but also an infrared absorbing material which is colorless and transparent in the visible region and absorbs at an infrared wavelength.
It is also possible to check with a scope. As an example of a substance that can be used, an infrared absorbing substance is exemplified by a phosphate-based white crystalline material powder containing phosphorus pentoxide as a main component and containing 1.0% by weight or more of iron oxide and / or copper oxide, and phosphorus pentoxide. Glass-based material containing Fe ²⁺ and / or Cu ²⁺ as a component, metal complex type infrared absorber, cyanine-based, phthalocyanine-based, naphthalocyanine-based, anthraquinone-based, aminium-based, croconic methine-based, azulenium-based And a part of an infrared-absorbing dye such as a pyrylium-based dye. The white crystalline material powder and the glass-based material contain the following compounds as necessary. [Containing Compound] Al ₂ O ₃ 2.0 to 10.0 wt% B ₂ O ₃ 1.0~30.0 wt% MgO 3.0 to 10.0 wt% ZnO 0 to 3.0 wt% K ₂ O 0-15.0% by weight BaO 0-10.0% by weight SrO 0-10.0% by weight Ni, Co, Se trace amount

Of the above-mentioned infrared absorbing substances, white crystalline material powder and glass-based material are preferable from the viewpoint of whiteness,
From the viewpoint of the infrared absorbing ability, a white crystalline material powder, a metal complex type infrared absorbing agent, and an infrared absorbing dye are preferable. A wax or the like is used as a binder used for applying these infrared absorbing materials. Further, the binder is preferably contained in an infrared absorbing ink composition excluding the solvent in an amount of 20% by weight or more.

FIG. 3 is an explanatory cross-sectional view of a lottery ticket to which a counterfeiting prevention measure has been applied in another embodiment of the present invention. As shown in FIG. 3, a light-impermeable shielding layer 9 is provided on one surface of the printing substrate 9.
a, and the light-impermeable shielding layer 9a is
Printing substrate 9 corresponding to the entire surface on one side of
On the back side of the substrate, solid printing with an ink mainly composed of carbon black, or a more effective metal deposition layer or metal foil can be used. Accordingly, it is possible to prevent the printing layer 8 from being determined from the back side, which determines the hitting and the loss, so that it is preferable to provide the shielding layer 9a.

In the case of a simple lottery ticket in which only a hit or a loss is determined, only the hit ticket is provided with a transfer adhesive layer 7 in which a fluorescent material or an infrared absorbing material is mixed. If a lottery is prepared by providing a transfer adhesive layer that does not mix an absorbing material, only
This can be determined by irradiation with a V lamp or an IR scope. That is, since the transfer adhesive layer is provided below the concealing layer, even if the concealment layer is scraped off, the transfer adhesive layer mixed with the fluorescent material or the infrared absorbing material and the transfer adhesive containing no fluorescent material or the infrared absorbing material are included. Since it is indistinguishable from the layer, it is a very effective method for determination by a UV lamp or an IR scope, and the cost is further reduced.

[0021]

According to the present invention, there is provided a printed layer of characters, numerals, patterns, or the like indicating a hit and a loss, and a first release layer and a first adhesive layer on a resin film so as to cover the printed layer. This is a lottery ticket concealed by a transfer foil in which a transfer adhesive layer in which a fluorescent material or an infrared absorbing material is mixed is sequentially laminated through a metal deposition layer via a second adhesive layer and a second release layer via a second adhesive layer. Therefore, by peeling off the metal deposition layer, the user confirms the character, number or pattern without noticing the colorless and transparent fluorescent material or the transfer adhesive layer containing the infrared absorbing material that covers the printed layer that determines the hit and loss. be able to. Therefore, it is difficult to forge or tamper with a transfer adhesive layer containing a fluorescent material or an infrared-absorbing material, and even in the event of tampering, transfer adhesion by irradiating this print layer with a UV lamp or IR scope. Since the light emission of the layer is disturbed, it can be easily determined. Further, unlike the conventional printing method, since the concealing layer, the transfer adhesive layer having the fluorescent material or the infrared absorbing material can be provided in one transfer, this lottery ticket can be manufactured at low cost.

Further, by adopting a configuration in which a black ink printing or a shielding layer made of a metal thin film is applied to the back side corresponding to the printing layer of the printing base material, the printing layer is prevented from being identified from the back side. Therefore, there is a further forgery prevention effect.
