Description

[0001]
[Industrial application fields]
The present invention relates to a lottery ticket for performing a desired lottery by scratching and peeling a concealing layer on lottery information formed on a support with a coin, a nail or the like.
[0002]
[Prior art]
Conventionally, a lottery information such as patterns, numbers, symbols, etc. formed on a support is displayed with a fragile concealing layer formed of silver or other opaque wax ink, or an ink mainly composed of a cellulose resin or a natural rubber resin. Lottery tickets that are concealed and peeled off from the support by scratching with coins, nails, etc., allowing lottery information to appear, and allowing the intended lottery to be used are widely used.
[0003]
However, there is an undeniable injustice to peel off the concealment layer of such a lottery ticket and conceal it with a similar silver paint after confirming the lottery information.
[0004]
On the other hand, the concealing layer is a single color such as silver and is not excellent in design.
[0005]
[Problems to be solved by the invention]
The present invention has been made in view of the above problems, and it is an object of the present invention to provide a lottery ticket that makes it difficult to conceal it with a similar silver paint after confirming the lottery information and has excellent design properties. And
[0006]
[Means for Solving the Problems]
The lottery ticket according to claim 1 is characterized in that the lottery information formed on the support is concealed so as to be invisible by a detachable hologram concealing layer.
[0007]
Hereinafter, it explains in detail using a drawing. FIG. 1 is a plan view showing a lottery ticket according to the present invention, and FIG. 2 is a sectional view.
[0008]
With the support 1 according to the present invention, mechanical characteristics that can be used as a lottery ticket, water resistance, chemical resistance, printing characteristics for printing lottery information, lottery information can be read through the light. Light opacity is required so as not to exist.
[0009]
Specifically, fine paper, art paper, coated paper, synthetic paper, resin film and the like can be mentioned.
[0010]
The lottery information 2 according to the present invention is not different from the lottery information of a normal lottery ticket, and includes letters such as hits and misses, numbers such as 1, 2, 3,..., And figures such as stars and fruits. .
[0011]
Moreover, as a preferable aspect of the present invention, the peeling varnish layer 3 may be provided on the support 1 including the lottery information 2. This is provided in order to prevent falsification of lottery information or to facilitate peeling of a hologram concealing layer to be described later.
[0012]
Such a release varnish layer 3 can be provided by applying and drying a transparent resin solution mixed with a lubricant such as silicon by a known coating method.
[0013]
Next, in order to conceal the lottery information formed on the support by the hologram concealing layer 7, a method using a hologram transfer foil is preferable because of its ease of manufacture. The invention described in claim 2 is based on such a technical background.
[0014]
That is, in the method for producing a lottery ticket according to claim 2, a release varnish layer is provided on a support on which lottery information is formed, and a hologram transfer foil having at least a substrate and a hologram concealing layer is pressure-bonded on the release varnish layer. The hologram hiding layer is transferred onto the release varnish layer.
[0015]
FIG. 3 is a cross-sectional explanatory view showing a lottery ticket manufacturing process according to the present invention.
When a press plate is pressure-bonded to the release varnish layer 3 of the support 1 from the substrate side of the hologram transfer foil, and heated and pressurized, the press-shaped hologram concealing layer is transferred onto the release varnish layer.
[0016]
In addition, the following three structures can be applied to the layer structure of the hologram transfer foil used for manufacturing such a lottery ticket.
[0017]
That is, the lottery ticket manufacturing method described in claim 3 is based on the invention described in claim 2 and is characterized in that the hologram concealing layer comprises a hologram forming layer, a reflective thin film layer, and a brittle adhesive layer. .
[0018]
As shown in FIG. 4, the hologram transfer foil for forming the hologram concealing layer 7 is obtained by sequentially laminating the hologram forming layer 6, the reflective thin film layer 5, and the brittle adhesive layer 4 on the substrate 8.
[0019]
Here, the base material 8 can serve as a temporary support until the hologram concealing layer is transferred, and a heat-resistant resin film such as a polyester film can be used.
[0020]
Further, the hologram forming layer 6 is formed by applying a thermoplastic resin, a thermosetting resin, an ultraviolet ray or an electron beam curable resin to a thickness of several μm on a base material by a coating forming method such as a gravure coating method, and drying it. This is a layer formed by heating and pressing a nickel stamper on which a hologram image (a tulip in FIG. 1) having a concavo-convex pattern is formed on the hologram forming layer.
[0021]
The reflective thin film layer 5 is a layer that reflects light incident from the hologram forming layer side. As a material for such a reflective thin film layer, metals such as aluminum, silver, gold, and tin can be used. As a method for forming such a reflective thin film layer, film forming means such as a sputtering method and an ion plating method can be applied in addition to the vacuum evaporation method, and the film thickness may be in the range of 400 nm to 500 nm. preferable.
[0022]
The reflective thin film layer may be formed before the hologram image is formed.
[0023]
The brittle adhesive layer 4 is a fragile layer, and as a result, it is a layer that makes it easy to destroy the entire hologram concealing layer by scratching it with coins or nails.
[0024]
As a material for forming such a brittle adhesive layer, wax-based, rubber-based, acrylic-based adhesive components, brittle components (components that do not contribute to adhesion) composed of inorganic fillers or extender pigments such as talc, and antioxidants The adhesive which added additives, such as these as needed, can be applied.
[0025]
However, when the reflective thin film layer is thin and the hiding power is small, the lottery information may be seen through. The invention described in claim 4 has been made in view of such a problem.
[0026]
That is, the method for producing a lottery ticket according to claim 4 is based on the premise of the invention according to claim 2, wherein the hologram concealing layer is composed of a hologram forming layer, a reflective thin film layer, and a brittle concealing adhesive layer. is there.
[0027]
The hologram transfer foil for forming such a hologram concealing layer is obtained by sequentially laminating a hologram forming layer 6, a reflective thin film layer 5 and a brittle concealing adhesive layer 11 on a substrate 8, as shown in FIG.
[0028]
Here, the base material, the hologram forming layer, and the reflective thin film layer are the same as those of the invention described in claim 3, but the brittle concealing adhesive layer is made of a material for forming the brittle adhesive layer, and further, titanium oxide and carbon. An opaque pigment such as black is added.
[0029]
By the way, the formation of the reflective thin film layer requires a film forming means such as a vacuum vapor deposition method, but the film forming means is very expensive. The invention described in claim 5 has been made in view of such a problem.
[0030]
That is, the lottery ticket manufacturing method described in claim 5 is based on the invention described in claim 2 and is characterized in that the hologram concealing layer includes a hologram forming layer and a brittle reflective adhesive layer.
[0031]
A hologram transfer foil for forming such a hologram concealing layer is obtained by sequentially laminating a hologram forming layer 6 and a brittle reflective adhesive layer 12 on a substrate 8 as shown in FIG.
[0032]
Here, the substrate and the hologram forming layer are the same as those of the invention described in claim 3, but the brittle reflective adhesive layer is a pigment having gloss such as an aluminum pigment in addition to the material forming the brittle adhesive layer. Is added. However, the sharpness of the hologram image having this configuration is slightly inferior to that having the reflective thin film layer.
[0033]
When transferring the hologram transfer foil to the support, the peelability between the substrate and the hologram hiding layer is better than the peelability between the brittle adhesive layer, the brittle hiding adhesive layer or the brittle reflective adhesive layer, and the peeling varnish layer. It is preferable.
[0034]
Further, a peeling layer may be provided between the base material and the hologram forming layer 6 or an anchor layer may be provided between the respective layers.
[0035]
And since the lottery ticket manufactured in this way has a hologram image, it was excellent in design nature and the lottery information was invisible. Moreover, once the hologram concealing layer is destroyed, it is difficult to reproduce it.
[0036]
Further, when the hologram concealing layer of the lottery ticket was scratched with a nail, the lottery information was confirmed by peeling cleanly from the peeling varnish layer as shown in FIG.
[0037]
