An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 3 and 4 show an embodiment of the lottery of the present invention (FIG. 3 shows a state in which the lottery of one embodiment of the present invention is opened). In the drawings, reference numeral 1 denotes a lottery according to the present invention. Is shown. The lottery 1 is composed of a printing base material 3 having a configuration in which a printing piece 3a and a transfer piece 3b are connected via a bending perforation 2 provided at the center. As shown in FIG. 4, the lottery 1 of the present invention is formed by bending the printing base material 3 at the perforation 2, overlapping the printing piece 3 a and the transfer piece 3 b, and applying pressure under pressure. . When the lottery 1 is opened, as shown in FIG. 3, a print image 5a as lottery information such as "AB" is formed on the print piece 3a. In addition, on the transfer piece 3b, a mirror image 7 of a blank character of the print image 5a is formed.

In order to manufacture the lottery 1 of the present invention, first, as shown in FIGS. 1 and 2, a releasable pressure-sensitive adhesive is applied to the surface of the printing substrate 3 to form a pressure-sensitive adhesive layer 4. After the transferable printing surface 5b is formed by halftone printing on the printing piece 3a constituting the printing base material 3 by superposing the pressure-sensitive adhesive layer 4 on the pressure-sensitive adhesive layer 4 and using an ultraviolet curable ink or an oxidative polymerization type ink. As shown in FIG. 1, a print image 5a as lottery information is formed in a non-transferable manner so as to overlap the print surface 5b. Next, the printing surface 5b
The printed piece 3 is formed in a semi-cured state while the ink forming
While the printing material 3 is not sufficiently fixed on the printing material 3, the printing base material 3 is bent at the perforation 2, the printed piece 3 a and the transfer piece 3 b are superposed on the surface provided with the adhesive layer 4, and both are pressure-bonded so that they can be separated. To wear. Thereby, the lottery 1 as shown in FIG. 4 is obtained.

[0009] The lottery 1 configured as described above is
The printed piece 3a is sufficiently formed in a state where the ink forming b is semi-cured.
Since the surface of the printing piece 3a and the transfer piece 3b on the side on which the adhesive layer 4 is provided is adhered in a state of being in close contact with the uncured ink forming the printing surface 5b before fixing. A part of the image is fixed on the transfer piece 3b in close contact, and the printed image 5
The ink which forms the printing surface 5b of the portion overlapping with a is
Since it is covered with the non-transferable ink forming the print image 5a, it does not adhere to the transfer piece and does not fix to the transfer piece. Therefore, the ink in the portion is fixed on the printed piece 3a as it is. As a result, when the lottery 1 is peeled off from the sticking surface 8 and opened, as shown in FIG. 3, together with the print image 5a representing the lottery information on the print piece 3a, the print image 5a is formed by the ink fixed on the transfer piece 3b. A corresponding letter-shaped mirror image 7 of lottery information is formed.

As the printing base material 3, paper, synthetic paper, synthetic resin film, metal and the like can be used, and these can be used by being appropriately laminated.

Examples of the removable adhesive constituting the adhesive layer 4 include, for example, Japanese Patent Application No. 2-134 filed previously by the present applicant.
No. 470, a pressure-sensitive adhesive in which styrene-butadiene rubber and microsilica are dispersed in water, or a natural rubber and styrene-butadiene as described in Japanese Patent Application No. 2-293978. It is possible to use a pressure-sensitive adhesive or the like containing an adhesive main agent composed of butadiene rubber and a resin having low compatibility with the adhesive main agent.

The UV-curable ink used to form the transferable printing surface 5b generally includes organic pigments, extenders, carbon black, titanium white, metal powder, etc. as coloring materials, and polyol acrylate-based prepolymers. And inks using monoacrylates, diacrylates, triacrylates and the like as monomers such as epoxy acrylates, urethane acrylates, polyester acrylates, alkyd acrylates and polyether acrylates. The oxidation polymerization type ink is generally called an oil-based ink, and examples thereof include those in which cobalt or manganese is added as an oxidation accelerator.

In order to print and form the print image 5a in a non-transferable manner, printing is performed with the above-mentioned ultraviolet curable ink or oxidative polymerization type ink, and thereafter the ink is completely cured, or a printing substrate such as toner. For example, a method of performing printing using a material having a good fixing property to the toner can be adopted. When the print image 5a is printed by a printer or the like using toner, various kinds of variable information can be represented as the print image 5a.

The above-mentioned pressure-sensitive adhesive can adjust the adhesive force by increasing or decreasing the amount of application or by increasing or decreasing the pressing force at the time of pressure-bonding. The degree of curing can be adjusted by adjusting the output and the irradiation time. In addition, the oxidation polymerization type ink can adjust the degree of curing by increasing or decreasing the amount of cobalt or manganese or the amount of ink applied, so whether to perform transfer printing or non-transfer printing, Alternatively, the material is appropriately adjusted and used in consideration of the material of the printing substrate, the material of the adhesive, the material of the ink, and the like.

In the embodiment of the present invention, the print image 5
Although the description has been made assuming that a is formed as lottery information by characters such as alphabets and the mirror image 7 of the print image 5a is transferred and formed as a mirror character of lottery information, the print image 5a is printed as a mirror character of lottery information and transferred. Accordingly, the present invention may be implemented such that a mirror image 7 is formed as lottery information.

Although the shape of the lottery 1 has been described as being formed by folding a rectangular printing base material into two,
The shape of the lottery 1 of the present invention is not limited to this, and various shapes such as a triangle, a star, a heart, and a flower can be considered. Also,
The printing piece 3a and the transfer piece 3b constituting the printing base material 3 may be separate and separate pieces. However, since the purpose is to prevent forgery and tampering, it is preferable that the two pieces are separated and integrated without separating, so that the two printed images can be easily compared. Further, if the print base material 3 can be covered and hidden when the print piece 3a and the transfer piece 3b are folded at the bending perforation 2 and the print piece 3a and the transfer piece 3b are folded, the print forming the print base material 3 is possible. The size of the piece 3a and the transfer piece 3b may be different. In order to make forgery or falsification more difficult, it is also possible to apply various patterns to the print image 5a or the print surface 5b.

As shown in FIG. 4, the printed piece 3a and the transfer piece 3b are easily peeled off at a part of the sticking surface 8 where the peeling is applied, for example, at the corner 6 of the lottery periphery. It is preferable to provide a non-adhering portion to such an extent that the lottery is not opened by mistake.

[0018]

According to the present invention, a lottery 1 is provided with a non-transferable print image 5a on a printing surface 5b, and before the ink forming the printing surface 5b is fully fixed to the printing material 3a in a semi-cured state. 3a and the transfer piece 3b were formed by pressing and adhering the surface of the side on which the pressure-sensitive adhesive layer was provided in close contact with the pressure-sensitive adhesive layer. A part of the ink excluding the portion where the ink 5a overlaps (the portion covered with the print image 5a) is transferred to the transfer piece 3b, and the print image 5
A mirror image 7 in the shape of the letter "a" is formed. This is because, due to the adhesiveness of the adhesive applied to the surface of the transfer piece 3b, the semi-cured ink forming the printing surface 5b is attracted to the adhesive, and the printing surface 5b is coated with the adhesive. Is formed by halftone printing on the printing piece 3a, the ink forming the printing surface 5b has a lower fixability to the printing piece 3a than when printing is performed directly on the printing piece 3a. On the other hand, on the other hand, the portion provided with the non-transferable print image 5a remains on the print piece 3a because the transfer to the transfer piece 3b is prevented by the print image 5a. For this reason, the printing image 5
Since a part of the ink forming the printing surface 5b of the portion where the “a” is not provided is also fixed and transferred onto the transfer piece 3b, the character image mirror image 7 of the print image 5a as the lottery information is transferred to the transfer piece 3b. 3b.

Since the character is formed as a blank character by comparing the two images, it is possible to confirm whether the character is a legitimate lottery or a lottery with a trace of forgery or falsification. Therefore, the presence or absence of forgery or tampering can be easily determined. In addition, since not only the lottery information but also the mirror image is formed, the time and effort for forgery and falsification are doubled, and it is possible to make forgery and falsification more difficult.
