  However, according to the above-mentioned Patent Documents 1 and 2, the secret information hiding layer has high designability before scratching, but cannot maintain the designability after being peeled off by scratching. In addition, since the person who performs the scratching is most interested in the content of the secret information, scratching the secret information concealment layer and confirming the secret information will significantly reduce the interest in the scratch card.

  SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and a scratch that does not reduce interest in the scratch after the scratch of the secret information hiding layer and can enhance the design of the scratch card after the scratch. Providing cards is the main challenge.

  The present invention for solving the above-mentioned problems is formed by printing first secret information with a base material and an ink composition containing a material having a hardness higher than that of a friction body in a region on the base material. A first secret information printing unit, a second secret information printing unit formed by printing the second secret information in another area on the substrate, and a part of the second secret information printing unit Or a secret card concealing layer laminated so as to cover all of the first secret information by the friction body scraped by scratching the first secret information printing unit with the friction body. The first secret information is expressed by coloring, and the secret information hiding layer is peeled off by scratching the secret information hiding layer with the friction body so that the second secret information is visible. .

  The first secret information printing unit may be formed in a halftone dot shape, and the second secret information may be information related to the first secret information.

  According to the present invention, since the secret information can be confirmed by scratching the area where the secret information hiding layer is provided and other areas, the interest in the scratch is reduced even after the secret information hiding layer is scratched. There is nothing. Furthermore, the secret information hiding layer can be removed by scratching, and the latent image can be raised by the color of the material of the friction body, so that high design can be imparted to the scratch card after scratching.

  First, the scratch card according to the first embodiment of the present application will be described with reference to FIG. FIG. 1 is a schematic sectional view of the scratch card of the present embodiment.

(First embodiment of the present application)
As shown in FIG. 1, in the scratch card 10 of the first embodiment of the present application, the first secret information printing unit 12 is formed in one area on the base material 11, and the second secret information is formed in the other area. The printing layer 13 is formed, and the peeling layer 14 and the secret information concealment are formed so as to cover a part or all of the second secret information printing unit 13 (in the case shown in FIG. 1, the whole second secret information printing unit 13). Layers 15 are stacked in this order.

  In the scratch card 10 of the present invention, the first secret information printing unit 12 is printed with the first secret information with an ink composition containing a material having a hardness higher than that of the friction body, and the first secret information is printed with the friction body. By coloring the first secret information with the material of the friction body scraped by scratching the information printing unit 12 to express the first secret information, and scratching the secret information concealment layer 15 with the friction body The secret information hiding layer is peeled off to make the second secret information visible. Hereinafter, each layer constituting the present invention will be described in more detail.

(Base material)
The base material 11 is used as a base for forming the first secret information printing unit 12 and the second secret information printing unit 13 on the base material 11, and the first secret information printing unit 12 and the second secret information printing unit. There is no particular limitation as long as the printing unit 13 can be formed, and conventionally known ones can be appropriately selected and used. For example, as the material of the base material 11, stretched and non-stretched sheets made of polyethylene terephthalate, polypropylene, polycarbonate, cellulose triacetate, etc. which are plastic sheets in addition to general fine paper, coated paper, synthetic paper, and aluminum foil laminated paper Etc. Moreover, as thickness of the base material 11, 25 micrometers-200 micrometers are common.

(First Secret Information Printing Department)
The first secret information printing unit 12 displays the first secret information such as “winning” and “out of” lottery, character data, images, marks, personal information, etc. on one area of the base material 11 than the friction body. It is formed by printing with an ink composition containing a material having high hardness. The content of the first secret information differs depending on the purpose of use of the scratch card and is not limited to the above secret information, and can be selected and formed as appropriate according to the purpose of use of the scratch card 10. In addition, one area on the base material in the present embodiment refers to an area where the first secret information printing unit 12 is formed.

  Here, the friction body is used for scratching the first secret information section 12, and the first secret information printing section 12 is scratched (friction, scratches, etc.) so that the friction body itself is scraped and If the first secret information can be expressed by coloring the first secret information with the material of the body and the secret information hiding layer 15 can be peeled off by scratching the secret information hiding layer 15 described later, There is no particular limitation. As such a friction body, a coin, a writing instrument, etc. can be mentioned, for example.

  The ink composition for printing the first secret information is constituted by incorporating a material having a hardness higher than that of the friction body described above into a pigment such as an inorganic pigment or an organic pigment, or a dye such as a basic dye or an acid dye. As long as a material having a hardness higher than that of the friction body is included, the material is not particularly limited. However, as a friction body used for scratches, coins are often used, and when the first secret information is printed with an ink composition of a material whose hardness is lower than the hardness of the metal of the coin, the metal of the coin is There is a risk that the first secret information may be deleted without being deleted. Considering such points, the material contained in the ink composition is preferably a material having a higher hardness than the metal of the coin. Examples of such materials include titanium oxide, aluminum oxide, silicon dioxide, and chromium oxide. Further, the ratio of the material having higher hardness than the friction body in the ink composition is generally in the range of 10 to 80%. In addition to the materials described above, vehicles and additives may be appropriately blended in the ink composition.

  The color of the 1st secret information in the 1st secret information printing part 12 can be suitably selected according to the color of the base material 11, and there is no limitation in particular about the color. However, when the first secret information is printed in a color different from that of the base material 11, the content of the first secret information is visually recognized before scratching. The color is preferably the same color. By making the color of the first secret information the same as the color of the base material 11, the first secret information can be a latent image, and the first secret information can be prevented from being visually recognized before scratching.

  The thickness of the first secret information printing unit 12 is not particularly limited, but when the first secret information printing unit 12 is formed by printing the first secret information with the same color ink composition as the base material 11 as described above. When the thickness of the first secret information printing unit 12 is 1 μm or more, the concealability of the first secret information may be deteriorated. Considering such points, the thickness of the first secret information section 12 is preferably smaller than 1 μm.

  Further, the range of the first secret information printing unit 12 formed on the base material 11 is not particularly limited, and can be appropriately formed in one region on the base material 11, as shown in FIG. The first secret information printing unit 12 may be formed at intervals, or the first secret information printing unit 12 may be formed continuously.

  Moreover, you may form the 1st secret information printing part 12 in the shape of a halftone dot, a thin line, a solid, and a blank. By forming the first secret information printing unit 12 so as to be dot-like, thin line, solid, and blank, it is possible to impart high designability to the first secret information expressed after scratching.

  The method for forming the first secret information printing unit 12 can be formed on the substrate 11 by appropriately selecting a conventionally known method. Examples thereof include a forming method using a flexographic printing machine, an offset printing machine, a gravure printing machine, a letterpress printing machine, an intaglio printing machine, a thermal transfer printer, a laser printer, a dot printer, an IJ printer, and the like.

(Second Secret Information Printing Department)
The second secret information printing unit 13 determines whether or not a lottery such as “hit” or “out” is applied to another region different from the region where the first secret information printing unit 12 is formed on the base material 11, character data, It is formed by printing the second secret information such as an image, a mark, personal information, etc. on the base material 11, and it becomes visible when the secret information concealing layer 15 described later is peeled off by the friction body. In addition, the other area | region on the base material 11 in this embodiment is an area | region different from the area | region in which the 1st secret information printing part 12 was formed, Comprising: The 2nd secret information printing part 13 and the 2nd mentioned later An area in which the secret information concealment layer 15 formed so as to cover the secret information printing unit 13 is formed.

  The information content of the second secret information is not particularly limited, and can be appropriately selected according to the use of the scratch card. The first secret information and the second secret information may be independent and unrelated information. The one secret information and the second secret information may be information that is related to each other. When the first secret information and the second secret information are related to each other, it is not necessary to scratch the secret information concealment layer 15 in order to confirm the contents of the information. The area where the layer 15 is not formed needs to be scratched, and the interest in scratching for confirming the content of information can be increased. In addition, the information having mutual relations includes, for example, “winning”, “missing” information, “1st class”, “2nd class”, etc. in a scratch card used for a lottery or the like. The content is not particularly limited as long as the information is relevant.

  The ink composition for printing the second secret information is information that becomes visible when the secret information concealment layer 15 provided on the top thereof is peeled off by scratch, so the first secret information is printed. It is not necessary to use a material having a hardness higher than that of the friction body as in the ink composition. Further, the method for forming the second secret information printing unit 13 is not particularly limited, and a conventionally known ink composition is appropriately selected, and the one region on the substrate 11 where the first secret information printing unit 12 is formed is It can be formed by printing on different regions using a flexographic printing machine, offset printing machine, gravure printing machine, letterpress printing machine, intaglio printing machine, thermal transfer printer, laser printer, dot printer, IJ printer, or the like.

(Confidential information hiding layer)
The secret information concealment layer 15 is formed so as to cover a part or all of the second secret information printing unit 13 and is provided to conceal the second secret information printing unit 13, and the second secret information is visually recognized before scratching. The second secret information is made visible by scratching.

  As described above, the secret information concealing layer does not make the second secret information visible before scratching, and if the secret information concealing layer can exhibit the function of being peeled off by scratch and making the second secret information visible, the material constituting the secret information concealing layer 15 It does not specifically limit about conventionally, A conventionally well-known material can be selected suitably and can be used. For example, natural rubber resins (natural rubber, hydrochloric acid rubber, etc.), diene resins (polybutadiene, styrene / butadiene copolymers, acrylonitrile / butadiene copolymers, polyisoprene, polychloroprene, etc.), acrylic resins, vinyl resins Resin used as a vehicle (component for transferring and fixing pigment to the surface to be printed), metal fine powder as colorant (aluminum powder, brass fine powder, copper fine powder), oxidized fine powder thereof, etc. Is formed by containing 40 to 60% by weight. Moreover, in order to improve the concealability of the foundation | substrate of the secret information concealment layer 15, you may contain 1-2 weight% of barium sulfate, calcium carbonate, etc. By configuring the secret information hiding layer 15 from the above composition, it is possible to satisfy both printability and scratch properties. The method for forming the secret information hiding layer 15 is not particularly limited. For example, the secret information hiding layer 15 can be formed by coating the base material 11 with the above composition diluted with a solvent.

  Moreover, it is good also as providing the peeling layer 14 between the 2nd secret information printing part 13 and the secret information concealment layer 15 as needed. By forming the release layer 14, it is possible to improve the peelability of the secret information hiding layer 15 when scratched by the friction body.

  As such a release layer 14, an acrylic resin, a vinyl resin, a polyester resin, a fiber resin, a wax, a melamine resin to which a release agent such as fluorine resin, silicone, or various waxes is added or copolymerized is used. Examples thereof include resins.

  Further, a protective layer may be formed so as to cover part or all of the secret information hiding layer 15 (not shown). By forming a protective layer, the scratch resistance of the secret information hiding layer 15 is improved, the secret information hiding layer 15 is peeled off by some contact, and the second secret information becomes visible before scratching. It can be effectively prevented. Examples of such a protective layer include a protective layer containing a peelable component such as silicone wax, polyethylene wax, and carnauba wax, and a protective layer made of a UV cured film or an EB cured film. Moreover, it is good also as giving the function as a protective layer in secret information concealment layer 15 itself by adding a peelable component to the material which comprises the secret information concealment layer 15. FIG.

  As shown in FIG. 2A, the first secret information printing unit 12 is formed in one area on the substrate 11, and the other area different from the one area where the first secret information printing unit 12 is formed is formed. A second secret information printing unit 13 is formed. 2A shows the first secret information printing unit 12 by a broken line and the second secret information printing unit 13 by a solid line for convenience of explanation, the first secret information printing unit 12 has the same color as the base material. By using the ink composition, the first secret information is made into a latent image, and the secret information concealing layer 15 is formed on the second secret information printing unit 13, so that the first secret information and the second secret are obtained before scratching. Information is not visually recognized, and only the secret information hiding layer 15 is visible.

  Here, as shown in FIG. 2 (b), by scratching one area on the base material 11, the first secret information printing unit 12 that was a latent image before scratching and could not be visually recognized is the friction body. By coloring the material color to express the first secret information and scratching the secret information concealment layer 15 formed in another region different from the one region, the secret information concealment layer 15 is peeled off and the second secret Information becomes visible. In this way, by forming the secret information printing unit on which the first secret information and the second secret information are printed in different areas, not only the area where the secret information concealment layer 15 is provided but also other areas are scratched. Thus, since all the secret information can be confirmed, the interest in the scratch is not reduced even after the secret information hiding layer 15 is scratched. Furthermore, the secret information concealment layer 15 is removed by scratching to make the second secret information visible, and the first secret information that is a latent image can be revealed before the scratch by the color of the material of the friction body. High designability can be imparted to the scratch card 10 after scratching.
