DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed matter with a scratch concealing layer used for lottery tickets, game cards, etc., and more particularly to a printed matter with a scratch concealing layer for preventing unauthorized use.

[0002]

2. Description of the Related Art Hitherto, in an instant lottery, a game card, or the like, a concealable scratch ink layer has been formed thereon in order to conceal information such as pictures, characters, numbers, etc. corresponding to "hits" and "losing". A printed matter is known. For example, as shown in FIG. 3, a confidential information layer (40) to be concealed is applied to a part of the printing paper (10) by printing or the like, and a confidential information layer (40) is formed thereon. A scratch concealing layer (50) made of silver ink or the like is applied so as to cover, and only this concealing layer (50) is peeled off with a nail or a coin so as to be scratched.
The contents of the confidential information layer (40) composed of pictures, characters, numbers and the like are known.

[0003] However, there is a problem that the contents of the confidential information layer (40) are illegitimately read by applying strong light from the back surface of the printing paper (10). .

[0004] For example, as shown in FIG.
There is a printing paper (10) in which an aluminum foil (12) of 10 to 10 μm is sandwiched, and a printing paper (10) using thick paper to block strong light from the back surface.

[0005] However, in order to make the printing paper (10) in which the aluminum foil (12) is sandwiched, sandwiching of a thin aluminum foil is a difficult technique, and there is a problem that a material cost is increased with a thick aluminum foil. .
Further, incineration processing is generally used in disposal processing of printed matter using the printing paper (10) after use, for example.
In this incineration process, aluminum melted into the grate of the incinerator entangles and deteriorates its movement, causing problems such as a decrease in incineration efficiency and damage to the grate, etc.In addition, aluminum is converted to alumina by incineration. In addition, there are many environmental problems related to the waste that humidification at the time of landfill disposal of incineration residue generates toxic ammonia gas adsorbed on the alumina.

In order to solve the cost and environmental problems of the aluminum foil (12), the present inventors have proposed:
Instead of the aluminum foil (12), a printing paper (10) sandwiched with black paper was trial-produced, and an attempt was made to produce a printed material with a scratch concealing layer. Scratch hiding layer (50)
Before printing, a varnish made of a non-aqueous ink is applied to the portion in advance, but the solvent permeates the printing paper (10) and becomes more transparent, so that the confidential information layer (40) such as the winning number of the lottery ticket is mechanically read. This confidential information layer (40)
There is also a fatal problem such that the color (density) difference between the image and the background becomes insufficient and reading becomes impossible.

When thick paper is used for the latter printing paper (10), troubles such as failures occur in the transport system of the printer for printing characters and numbers to be concealed, or strong light from the back surface. Confidential information layer (40)
Or the back surface (scratch hiding layer (50)
And the like, but a black ink layer may be applied to the back side of the thick paper corresponding to the above. However, the design of the back side of the printing paper (10) is lacking, the area of general printing on the back side is restricted, and However, there is also a problem that there are many restrictions such as that the machine cannot read the confidential information layer (40).

[0008]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide a printed matter with a scratch concealing layer used for a lottery ticket or a game card.

Embodiments of the present invention will be described below. As shown in FIG. 1, the printed matter with a scratch concealing layer according to the first aspect of the present invention comprises a black ink coating layer (20) on one surface of a relatively thin printing paper (10) made of high quality paper or the like. , A white ink coat layer (30) is sequentially applied, and a confidential information layer (40) composed of pictures, characters, numbers, and the like on a part of the other surface, and a scratch hiding layer (50) composed of silver ink or the like.
Is a printed matter (1) with a scratch concealing layer which is successively applied.

By using a relatively thin high-quality paper or the like as the printing paper (10) in this way, no trouble occurs in the transport system of the printer for printing characters and numbers to be concealed, and the printing paper (10) ), The black ink coating layer (20) does not show through from the side of the confidential information layer (40) as compared with sandwiching black paper during), so that the confidential information layer (40) can be read by machine. It can be.

Further, by applying the white ink coat layer (30) on the black ink coat layer (20), there is no restriction on the area of the general print layer (42) on the back side, and there is no problem in the design. No printed matter with scratch concealing layer (1), and because it does not use aluminum foil, it has an advantage in manufacturing costs including materials, and is also environmentally friendly to waste. (1) can be a printed matter with a scratch hiding layer capable of blocking the strong light.

Further, as shown in FIG. 2, the printed matter with the scratch concealing layer according to the second aspect of the present invention is provided on one surface of a relatively thin printing paper (1) made of high quality paper or the like to prevent penetration. A white ink coat layer (32), a black ink coat layer (20), and a white ink coat layer (30) are sequentially applied, and a confidential information layer including a picture, a character, a number, and the like is partially applied to the other surface. (40), a scratch hiding layer (50) is sequentially applied. That is, a permeation prevention white ink coat layer (32) is added between the printing paper (10) and the black ink coat layer (20) of the printed matter (1) with the scratch concealing layer of the invention of claim 1.

As described above, by adding the permeation preventing white ink coat layer (32), permeation due to varnish printing made of a non-aqueous ink is eliminated, and the black ink coat layer (2) is removed.
0) becomes opaque, making it easier and more secure to read the confidential information layer (40) such as the winning number of the lottery ticket by mechanical reading. 32), the whiteness as viewed from the surface of the printing paper (10), that is, the surface of the confidential information layer (40) is increased, and the design of the general printing layer (44) on the surface is not restricted. . Other effects, that is, there is no restriction on the design of the general print layer (42) on the back side and there is no problem with the design, the production cost including materials is superior, and environmental issues related to waste are considered.
The ability to block the intense light from the back surface is equivalent to the first aspect of the present invention.

The printing paper (10) used in the present invention varies depending on the type of the printed matter (1) with a scratch concealing layer, but is premised on the use of a printer for printing characters and numbers to be concealed as described above. Therefore, relatively thin paper is preferable. For example, the basis weight is 40 g / m ^{2 to} 160 g.
g / m ² of high-quality paper, medium-quality paper, or coated paper, but is not limited to this paper type.

The ink of the black ink coat layer (20) varies depending on the printing (or coating) method, and includes a gravure coating method, a roll coating method, an offset printing method, and the like.
Inks compatible with screen printing and the like are used.

The thickness is preferably large for the purpose of blocking strong light from the back surface. However, in a method with high production efficiency such as a gravure coating method or an offset printing method,
The upper limit is 1 μm to 3 μm, and the density of black ink can sufficiently compensate for the desired light-shielding property.

The white ink coat layer (30) and the permeation prevention white ink coat layer (32) have the same thickness and printing (or coating) method as the above-mentioned black ink coat layer (20), and have the scratches of the present invention. The printed matter (1) with a hiding layer can be obtained.

A non-aqueous transparent varnish is usually applied on the confidential information layer (40) in order to prevent the confidential information layer (40) from being peeled off when the 0) is scraped off, and then the scratch hiding layer (50) is formed. is there.

[0021]

As described above, the present invention has the following effects. That is, a black ink coating layer and a white ink coating layer are sequentially applied to one surface of a relatively thin printing paper made of high quality paper or the like, and a confidential information layer formed of a pattern, a character, a number, etc. is partially applied to the other surface. Since the printed matter with the scratch concealing layer is formed by sequentially applying the scratch concealing layer made of silver ink or the like, no trouble occurs in the transport system of the printer that prints the characters and numbers to be concealed, and the printing paper can be printed. The black ink coat layer does not show through from the confidential information layer side as compared with the case where the black paper is sandwiched, so that the confidential information layer can be machine-readable. Furthermore, since there is no restriction on the area of the general printing layer on the back side, and no aluminum foil is used,
A printed material with a scratch concealing layer that can block strong light from the rear surface and is capable of responding to unauthorized use, which is superior in manufacturing costs including materials and in consideration of environmental problems related to waste.

Further, by adding a permeation prevention white ink coat layer between the printing paper and the black ink coat layer of the printed matter with the scratch concealment layer having the above-mentioned structure, the confidential information layer can be more easily and mechanically read by the machine to ensure the scratch concealment. The printed matter with a layer can be obtained, the whiteness seen from the surface of the printing paper can be increased, and there can be no restriction on the design of the general printed layer on the surface.

Therefore, the present invention exerts an excellent practical effect on printed matter with a scratch hiding layer such as a lottery ticket represented by an instant lottery ticket.
