Disclosure of the invention

Problems to be solved by the invention

However, according to the scratch card disclosed in the above publication, the concealment information is printed on the heat-sensitive layer on the back side of the scratch layer by pressing the thermal head of the thermal printer on the upper surface of the scratch layer. On the surface of the layer, concave portions along the characters constituting the concealment information were slightly formed, and the M portion was slightly invisible because of its slight depth. There was also concern about the situation.

[0004] The present invention has been made in view of the above-described conventional circumstances, and the problem to be solved is that the concealment information cannot be visually observed during manufacture, and the concealment information must be visually observed after manufacture. It is an object of the present invention to provide a method of manufacturing a scratch card that is surely impossible.

Means for solving the problem

Replacement paper (Rule 26) [0005] The means employed by the present invention in order to solve the above problems is to form a varnish layer on a heat-sensitive layer obtained by applying a heat-sensitive layer on a card base material, and form a scratch layer directly on the surface of the varnish layer. After the formation, a laser beam set so as not to cool each layer including the card base material is aligned on the surface of the scratch layer from a position away from the scratch layer to the surface of the heat sensitive layer. Irradiation prints concealment information on the heat-sensitive layer of the card base on the back side of the varnish layer (first invention).

[0006] Here, the formation of the base layer on the heat-sensitive layer formed on the card base includes the case where another layer is interposed between the card base and the varnish layer. For example, it includes an embodiment in which a varnish layer is directly formed on a heat-sensitive layer laminated on a card substrate.

Also, printing concealment information on the heat-sensitive layer of the card base on the back side of the varnish layer means that the laser light is applied to the surface of the heat-sensitive layer on the surface of the card base on the back side of the varnish layer where the scratch layer has been applied. For example, the surface of the heat-sensitive layer provided on the card substrate is included as long as the heat-sensitive layer can be printed.

[0007] Further, the laser beam set so as not to cool each layer including the card substrate is, for example, a distance from the laser beam irradiation position to the surface of the heat sensitive layer of 45 cm, and a laser beam. This is a laser beam with a moving speed of 1450 mm / s, a frequency of 99.9 KHz, and a current value of 16. OA to 18.1 A (second invention). In order to perform printing reliably, it is optimal to set the current value within the range of 17.6 A to 18.1 A (the third invention).

In addition, a heat sensitive layer may be applied on the card base material with printing of general information or the like (fourth invention).

The invention's effect

[0008] According to the present invention, the following excellent effects can be expected.

According to the first invention, the surface of the scratch layer can be adversely affected by the heat of the laser beam and can be maintained flat, and the concealment information can be printed without adversely affecting the varnish layer. Can provide a simple method.

In addition, since the heat-sensitive layer on which the concealment information is printed is covered with the varnish layer, the concealment information can be protected and a method for improving the scratch property of the scratch layer is provided. Can do.

According to the second invention, it is possible to specifically provide a method for irradiating the surface of the scratch layer with laser light that can be printed without adversely affecting the surface of the scratch layer.

According to the third invention, it is possible to specifically provide a method of irradiating the surface of the scratch layer with laser light that can reliably print without adversely affecting the surface of the scratch layer. According to the fourth invention, it is possible to provide a method capable of reliably printing on a card substrate on which general information or the like is printed.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, a method for manufacturing a scratch card, which is the best mode for carrying out the present invention, will be described with reference to the drawings.

In the manufacturing method of the present embodiment, after the scratch layer 12 is formed on the heat-sensitive layer 14a of the card base material 11 on which the heat-sensitive layer 14a is applied with the printing of the general information 14 or the like on the card base material 11, A plurality of card base materials 11 are formed by cutting into a predetermined shape, and a laser beam is aligned with the surface of the scratch layer 12 of the card base material 11 from the position separated from the scratch layer 12 to the surface of the heat sensitive layer 14a. As a result, the concealment information 13 is printed on the heat-sensitive layer 14 a on the back side of the scratch layer 12 to produce the scratch card A.

[0010] Hereinafter, the production process will be described in detail.

FIG. 1 is a cross-sectional view of a main part showing a method for manufacturing the scratch card A.

In the first step, after the general information 14 is printed on the surface of the card base 11, the heat-sensitive layer 14a is applied. (See Figure 1 (a)).

[0011] The card base 11 provided with the heat-sensitive layer 14a can be printed on the surface of the heat-sensitive layer 14a by irradiation with a laser beam in accordance with a standard described later, and printed on the heat-sensitive layer 14a on the back side. Use at least an opaque synthetic resin material that prevents the concealed concealment information 13 from being seen through.

Examples of the opaque synthetic resin material include colored polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and polyacetal (POM). The invention of the present application is not limited to the synthetic resin material, but includes paper materials and other materials that are generally used for printing. [0012] The general information 14 is information such as management information 16 that can be visually checked because it is not concealed by the surface side force scratch layer 12 of the scratch card A, and the card base material by a known general printing means or the like. Applied to 11 surfaces.

Note that the general information 14 may be partially applied to a necessary portion of the force scratch card A printed over substantially the entire surface of the scratch card A according to an example shown in FIG.

Specific examples of the general information 14 include characters and figures printed on the surface of the scratch card A, or partially or entirely colored on the surface of the scratch card A. Is.

[0013] Next, in the second step, a varnish layer 15 is formed on the surface of the thermosensitive layer 14a (see FIG. 1B).

The varnish layer 15 is formed by applying a transparent coating material having a silicone or wax-based synthetic resin strength so as to cover at least the concealment information printing region 13 ′ on which the concealment information 13 is printed. According to one example shown, the scratch card A is applied to substantially the entire surface so as to cover the concealment information print area 13 ′ and the general information 14 print area.

This varnish layer 15 displays the print area of the general information 14, the concealment information 13 described later, the print concealment information print area 13 ', and the management information 16 printed or printed with information managed by the scratch card A. In addition to covering and protecting the area and the like, the scratch resistance of the scratch layer 12 described later is improved.

[0014] In the third step, the scratch layer 12 is formed in the concealment information printing region 13 'on the upper surface of the varnish layer 15 (see FIG. 1 (c)).

The scratch layer 12 applies a mixture of aluminum fine powder and ink on the upper surface of the varnish layer 15 so as to cover the concealment information 13 to be printed later on the heat sensitive layer 14a, which will be described later. It is a layer that is easily peeled off by being pulled (scratched).

Therefore, the card substrate 11 applies the varnish layer 15 on the heat-sensitive layer 14a, and forms the scratch layer 12 in the concealment information printing region 13 ′ on the varnish layer 15.

[0015] In the fourth step, the surface of the heat sensitive layer 14a from the position where the laser beam is separated from the scratch layer. By irradiating the surface with the standard, the concealment information 13 having characters and figures is printed on the heat-sensitive layer 14a on the card base 11 side of the varnish layer 15 on the back side of the scratch layer 12. (See Figure 1 (d)).

Further, similarly, the management information 16 is printed on the surface of the heat-sensitive layer 14a where the scratch layer 12 of the card substrate 11 is not formed (see FIG. 2).

Further, the management information 16 is a visible character or symbol for managing the scratch card A, and is printed in advance using a known printing means between the first step and the second step described above. Well, okay.

The laser light is emitted from a laser oscillation tube 22 oscillated from a laser oscillator (not shown) and separated from the scratch layer 12, and the kind of the laser light is applied to the surface of the heat sensitive layer 14a on the card substrate 11. It has the effect of printing concealment information 13 consisting of characters, symbols, etc. irradiated in accordance with the standard. For example, a YAG laser, a semiconductor laser, or the like is used.

The laser oscillation tube 22 is configured to move in a horizontal direction along the surface of the card base 11 by an XY movement mechanism (not shown). Characters, symbols, and the like are received by a command from a control unit (not shown). Is controlled to form.

[0016] Next, in the fifth step, the card base material 11 subjected to the above steps is cut into a predetermined card shape such as a rectangular shape (see FIG. 2), so that a plurality of the scratch cards A Is completed.

[0017] It should be noted that in the present embodiment, after the first 14th step, the large-sized card base material 11 is cut into a plurality of pieces, so that the scratch card A is efficiently mass-produced. Although the embodiment is shown, the first 14th step may be applied to the surface of the card base material cut into the size of one scratch card A in advance.

Further, in the present embodiment, the concealment information printing area is exemplified as one part of the card base material, but the present invention is not limited to this, and the entire surface of the card base material is not limited thereto. You can also set the concealment information print area! You can also set the concealment information print area as multiple places.

Example Hereinafter, specific irradiation conditions of the laser beam used in the manufacturing method will be described. The concealment information is concealment information when the distance from the laser light irradiation position to the surface of the heat sensitive layer is 45 cm, the moving speed of the laser light is 1450 mm / s, and the frequency is 99.9 KHz. Table 1 shows the range of current values that can be printed as seen in the print area and not visible from the scratch layer!

[0019] [Table 1]

[0020] Based on the results of [Table 1] above, the current value of the laser beam capable of printing the concealment information so that it is not visible from the scratch layer and can be discriminated with the scratch layer peeled off is 16. OA 18. The current value of the laser beam that can be reliably printed in the range of 1A is in the range of 17.6A-18.1A. In other words, if the current value is less than 16.OA, the concealment information is not printed, and if it exceeds 18.1A, the surface force concealment information of the scratch layer is visible, so it cannot be used as a product at all. . In addition, it is possible to perform printing that allows discrimination of concealment information within a current value range of 16. OA-17.1 A.

In addition, when the current value is in the range of 17.2A-17.5A, it can be printed within the allowable range for the product. In addition, when the current value is in the range of 17.6A-18.1A, complete printing is possible as a product.

[0021] In addition, even when the laser beam irradiation position force is less than 45cm to the surface of the heat sensitive layer or when the laser light is irradiated to a different medium, the current value is set and the laser light moves on the surface of the heat sensitive layer Reliable printing is possible by setting the moving speed and frequency.

Industrial applicability

[0022] The method for producing a scratch card of the present invention can be used, for example, in a method of printing with a laser beam between layers of a multi-layered product having no scratch layer.
