Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed material with a scratch masking layer in which confidential information data is masked by a scratch masking layer such as a lottery ticket and a game card. The present invention relates to a printed material with a scratch concealing layer that recognizes confidential information data by scratching off (scratching off).

[0002]

2. Description of the Related Art Conventionally, for example, in an instant lottery ticket or a game card, in order to conceal confidential information data such as "hit", "miss" or a pattern corresponding thereto, hiding and scratching properties ( Scratch printed material in which the confidential information data is hidden by a rubber-based ink that has scratch resistance and has cohesive destruction properties, and the purchased customer uses the coin to scratch off the confidential information data when using it. Are known and used in various fields.

As a printed matter provided with the scratch concealing layer, for example, as shown in a schematic view of a laminated cross section of FIG. 4, a pattern, a character,
The confidential information data (12) such as numbers are printed,
An easily peelable layer (14) made of a transparent peeling varnish or the like is formed so as to cover the confidential information data (12), and a scratch masking layer (20) is provided on the easily peelable layer (14). Yes, a customer who purchases this scratch printed matter scratches off (scratches) the scratch concealing layer (20) with a coin, a nail, or the like, and the confidential information such as "hit", "off", or a corresponding pattern. The data (12) can be visually recognized.

[0004]

However, when the base material (10) is a relatively thin paper, for example, when this printed matter is exposed to strong light and viewed from the opposite side, the confidential information data (12) is obtained. There is a problem that security is lacking because the shadow of () is transparent and it is not confidential information data.

As a method of solving this problem, for example, as shown in the schematic view of the laminated cross section of FIG.
There is a method of providing the watermark prevention layer (24) on the back surface of (0) by printing with a gray ink, but there is a limit to the amount of information on the back surface, and it does not look good in terms of design and there is no freedom. Problematic or scratch masking layer (20)
Use a thick paper, knowing that it is difficult to print or process it (production efficiency deteriorates) because the base material (10) is expensive and it is supplemented with a method such as thickening it twice. I was solving this transparent problem.

[0006] In any of the above-mentioned measures to prevent the shadow of the confidential information data (12) from being seen through even when exposed to such strong light, materials such as the base material (10), ink, printing, etc. There is a problem that the number of steps is increased, that is, a so-called manufacturing cost is increased.

Further, the outermost scratch hiding layer (20)
Is a function of concealing the confidential information data (12), and is therefore an opaque solid image of silver or gray (in printing terms, there is no difference in lightness or darkness on the printed surface,
It is inevitable that the scratch concealing layer (2) is completely covered with printing ink.
The scratch print had a problem that there was no degree of freedom in the design of 0) and it did not look good in terms of design.

Furthermore, a screen printing method is generally used to form the outermost scratch concealing layer (20) with a thickness of about 4 to 10 μm. As the ink, for example, aluminum powder 15 to 25 is used. Parts by weight, 15 to 25 parts by weight of a coloring pigment including an extender pigment such as white alumina,
15 to 25 parts by weight of synthetic rubber resin such as SBR and NBR having cohesive failure (nodule), 35 to 45 parts by weight of aromatic hydrocarbon solvent such as toluene, xylene and methyl isobutyl ketone, and an antifoaming agent 5 to 15 parts by weight of the agent is added to form an ink for screen printing, and thus a rubber-based (scattered) rubber having cohesive failure (nodule) properties is obtained.
Since the thickness of the ink is as thick as about 4 to 10 μm, there is no sharpness in the image, and the line speed is slow for scratch inks for screens that have a slow drying property. In the meantime, since the leveling of the ink progresses and the irregularities of the confidential information data (12) appear on the surface of the scratch concealing layer (20), there is a problem that it is not confidential. Furthermore, since it is slow-drying, it is inferior in productivity, and it is unsuitable for in-line processing particularly in an offset printing machine that prints other images, so that it has to be formed on a separate line.

The present invention solves the above-mentioned problems of the prior art. The problem is that even if a strong light is applied, the shadow of the confidential information data cannot be visually recognized from the opposite surface thereof with a scratch concealing layer. In printed matter, there is no problem that the backside design has no freedom as in the past by giving a watermark prevention layer, there is no problem that it does not look good, the scratch masking layer is printed twice, or it is expensive and printing or processing is done. There is no problem that the manufacturing cost is increased by using difficult thick paper, and furthermore, the image of the scratch concealing layer on the outermost surface has sharpness, and in-line processing with an offset printing machine is used to form the scratch concealing layer. It is an object of the present invention to provide a printed material with a scratch masking layer that is made of a scratch masking layer that enables the design, has flexibility in design, and looks good.

[0010]

In order to achieve the above object in the present invention, first, in the invention of claim 1, a non-peeling layer formed of an image of confidential information data and a non-peeling layer around the non-peeling layer are formed on a base material. An easily peelable layer having a layer as a non-image portion is applied, and a colored color so as to cover the non-peelable layer and the easily peelable layer thereon, and a scratch concealing layer-attached printed matter which is provided with a full-face solid scratch concealing layer. The confidential information data is a printed material with a scratch masking layer, characterized in that it comprises a scratch masking layer on a non-peeling layer that is not scratched off by scratching off.

According to the first aspect of the present invention, the confidential information data is an image formed of the scratch masking layer on the non-peeling layer which is not scratched off by scratching off. Before scratching off, it is integrated with the scratch concealment layer on the easy peeling layer with the same thickness, so even if you give it a strong light and make a watermark, it becomes a scratch concealment layer printed matter that is difficult to see as confidential information data,
As a result, there is no need to apply a watermark prevention layer on the back surface unlike the conventional prints with a scratch masking layer, so there is more freedom in designing the back surface, and there is no need for double printing of the scratch masking layer or thick paper. It also reduces costs.

Further, as described above, since the scratch concealing layer on the easily peelable layer is visually recognized as confidential information data,
Since it is not necessary to thicken the scratch masking layer as in the conventional case and to increase the masking property, the ink for forming the scratch masking layer may be a colored ink without increasing the amount of aluminum powder or the like that deteriorates printability, As for this printing method, in addition to screen printing, a gravure method with high production efficiency, a roll coating method using a resin relief plate, a flexo method, or the like can be applied.

Further, in the invention of claim 2, a non-peeling layer formed of an image of confidential information data and an easy-peeling layer having a non-peeling layer as a non-image portion are provided on the base, and the above-mentioned layer is formed on the non-peeling layer. A printed material with a scratch masking layer, which is colored so as to cover the non-stripping layer and the easy peeling layer, and is provided with a scratch masking layer having a regular or irregular line drawing pattern, wherein the confidential information data is scratched off. A printed material with a scratch masking layer, comprising a scratch masking layer on a non-peeling layer that is not scraped off.

According to the second aspect of the invention, as in the first aspect, before scratch-off, it is integrated with the scratch concealing layer on the easy peeling layer with the same thickness, so that it gives strong light. Even if you watermark it, it will be a print with a scratch concealment layer that is difficult to see as confidential information data.As a result, you do not need to apply a watermark prevention layer on the back side unlike the conventional print with a scratch concealment layer, so you can freely design the back side. The scratch concealment layer is increased in number and does not require double printing of the scratch concealing layer or thick paper, which reduces the manufacturing cost. By forming a crest, or a line drawing pattern composed of a line drawing pattern, etc., the degree of freedom in designing the scratch concealing layer on the outermost surface is provided, and the scratch concealment looks attractive in terms of design. We can provide with printed material.

Further, in the invention of claim 3, the non-peelable layer and the easily peelable layer are colorless or pale images of the same color, and the printed material with the scratch concealing layer according to claim 1 or 2, Is.

According to the third aspect of the present invention, the non-peelable layer and the easy-peelable layer are colorless or light in the same color image (pattern), so that the scratch concealing layer has a regular or irregular line drawing pattern. Even when a part of the non-peelable layer and the easy-peelable layer is visible, or even when viewed through a watermark, the boundary between the non-peelable layer and the easy-peelable layer is not visually recognized. Can be a printed material with a scratch concealment layer that is not visible, and can provide a contrast between the non-peelable layer and the easily peelable layer when the colored scratch concealment layer forms confidential information data. .

Further, in the invention of claim 4, the scratch masking layer is made of a scratch printing ink using a styrene acrylic resin and / or a urethane resin as a binder. It is the printed material with the scratch concealment layer described.

According to the fourth aspect of the present invention, the scratch masking layer is formed with a printing ink having excellent adhesiveness using a styrene-acrylic resin and / or a urethane resin as a binder. There is a large difference in the adhesiveness between the release layer and the non-release layer, and as a result, the adhesion is further improved with respect to the non-release layer that forms the non-image area of the easy-release layer, and scratch-off during use results in the easy-release layer. It is easily scratched off, but remains on the non-peeling layer without being scratched off, and the remaining portion is recognized as confidential information data, and the printing ink for the scratch concealing layer is Compared to slow-drying inks that use synthetic rubber resins such as SBR and NBR as binders, they dry faster, so regular or irregular line drawing patterns, eg In parallel line, dot, Hosomon or line drawing pattern or the like is not or flow and leveling, thus excellent in sharpness and the like, can provide a printed matter with scratch concealing layer to look good on the design of the scratch masking layer on the outermost surface. Furthermore, since this ink for scratch concealment layer is quick-drying, it forms a film without leveling, and the step at the boundary between the easily peelable layer and the non-peelable layer is not visually recognized as confidential information on the surface, and it is It is possible to provide a printed material with a scratch masking layer that enables the in-line printing.

The term "solid surface solid" as used in claim 1 is a printing term and refers to a portion which is completely covered with printing ink without any difference in lightness and darkness or white portions.

When the scratch concealing layer (20) of No. 1 is scratched off (scraped) with a coin or the like, the scratch concealing layer (20) on the easy peeling layer (14) is peeled off to the right half of FIGS. 1 (b) and (c). The scratch concealing layer (20) left on the non-peeling layer (16) without being scratched off by the scratch-off as shown forms an “O” character, and this “O” character forms the confidential information data (12). It was made to become.

As the easily peelable layer (14), the scratch concealing layer (20) is made of an ink that is easily scratched off. For example, silicone acrylic resin, polyamide resin, nitrocellulose resin, or silicone or wax (polyethylene wax, etc.) as an additive. 5% by weight or less is added by screen printing, gravure printing, flexographic printing by printing through an anilox roller, or the like.

Further, for example, a release varnish obtained by adding about 5% by weight of a lubricant (silicone, polyethylene wax, etc.) to the vehicle of the offset ink (a component of the printing ink excluding the color pigment and additives) is used. Examples of the resin include 20 to 30% by weight of rosin-modified phenol resin and alkyd resin as resin, 10 to 20% by weight of soybean oil, linseed oil and tung oil as vegetable oil, and 25 to 3 as solvent.
To the vehicle of the offset oil-based sheet-fed ink consisting of 5% by weight of mineral oil, naphthene, paraffin, etc., the above silicone, polyethylene wax, etc. were added, and further added as an additive.
There is mentioned an offset oily type release varnish composed of a dryer made of cobalt naphthenate of 10 wt% or the like, an oxidation inhibitor, a set-off preventing agent, etc. Further, for example, a photopolymerizable material of 30 to 90 wt% is used. Acrylic esters of polyols, polyesters, urethanes, and epoxies, 10 to 40% by weight of ketone resins as modifying resins,
To the vehicle of the UV curable offset sheet-fed ink made of petroleum resin, alkyd resin, etc., the above silicone, polyethylene wax, etc. are added, and as an additive, 5-10
Examples include UV-curable offset release varnishes composed of a photopolymerization initiator composed of wt% benzophenone, benzyl, dimethylamine benzophenone, and additives such as thermal polymerization inhibitors such as hydroquinone. From this point of view, it is an ink (varnish) for an easily peelable layer, which is suitable for the production of this printed material with a scratch masking layer, and is formed by an offset printing method.

On the other hand, as the non-peeling layer (16), for example, in addition to the above-mentioned vehicle of the UV curable offset sheet-fed ink, a vehicle of a usual oxidation polymerization type offset sheet-fed ink or a vehicle of a gravure ink is transparent. A colorless varnish is preferably used, and the one having a large difference in adhesiveness with the scratch concealing layer (20) from the above-mentioned easy peeling layer (14) is preferably used. Therefore, the scratch concealing layer (20) on both sides is used.
Is peeled off on the easy peeling layer (14) due to scratch-off, and remains unpeeled on the non-peeling layer (16), which is visually recognized as secret information data (12).
It should be noted that these colorless varnishes (inks) may be lightly colored, but particularly when the scratch masking layer (20) is a line drawing such as lines as in the invention of claim 2, the ink for the easily peelable layer is used. Must be the same color as.

In the scratch-covered printed matter (1) having the above-described structure, as shown in FIG. 1 (a), the scratch-protection layer (20) on the non-peeling layer (16) which becomes the confidential information data when scratched off. ) And the scratch concealing layer (20) on the easy peeling layer (14) are integrated with the same thickness, and the non-peeling layer (16) and the easy peeling layer (14) are colorless or have the same color. The printed matter (1) with a scratch masking layer, which is difficult to be visually recognized as the confidential information data (12), can be obtained even when it is watermarked by applying strong light. Further, since it is not necessary to apply the watermark prevention layer (24) to the back surface unlike the conventional printed material with the scratch concealing layer shown in FIG. 5, it should be provided with the merit of increasing the amount of information such as the back surface design and the degree of freedom. You can

Further, in the present invention, as shown in the side sectional view of FIG. 2 (a), the whole surface solid scratch concealing layer of the invention of claim 1 is provided, for example, in a regular line pattern (20a).
It is what When the scratch-shielded printed matter (1) having the scratch-shielding layer having such a regular line-shaped pattern (20a) is scratched off, FIG.
As shown in (b), the scratch masking layer on the easy peeling layer (14) is scraped off, and the scratch masking layer on the non-peeling layer (16) is a regular line-shaped pattern (20a) as confidential information. It becomes visible as data (12).
In this way, the scratch concealing layer is formed into a regular line-shaped pattern (20a) before and after scratching off, thereby giving a degree of freedom to the design of the outermost scratch concealing layer and the confidential information data. The scratch-covered layer-attached printed matter (1) that looks good can be obtained.

In the above example, the scratch concealing layer has a regular line-shaped pattern (20a), but the regular line drawing pattern may be, for example, a halftone dot pattern, a grid pattern, or an oblique grid pattern. The irregular line drawing pattern may be, for example, a tint block, a thin pattern, or a scratch masking layer composed of a camouflage pattern (20b) as shown in FIG. 3, and further, a pattern composed of lines. Examples include a pattern composed of coarse (60 lines / inch or less) halftone dots, which can be appropriately selected as the scratch concealing layer (20) that looks good in design by these line drawing patterns.

Further, in the present invention, as shown in FIG. 1 (a), a scratch masking layer (20) is formed by using a printing ink containing styrene acrylic resin and / or urethane resin as a binder. The layered printed matter (1) is used.

The composition of the printing ink for scratch forming the scratch concealing layer (20) is, for example, a colored ink,
20-45 parts by weight of an aluminum paste (a fine aluminum powder is surface-treated with fatty acid or the like and made into a paste with mineral spirit having a high boiling point) and a coloring pigment to give a certain degree of hiding and scratching properties, a binder As a polyurethane synthetic resin or a styrene / acrylic copolymer resin, or a mixture of a polyurethane synthetic resin and a styrene / acrylic copolymer resin 25-
50 parts by weight, 1 to 10 parts by weight of an auxiliary agent such as an antifoaming agent, 10 to 3 parts
Examples thereof include those dispersed in 5 parts by weight of water and less than 5 parts by weight of a lower alcohol such as isopropyl alcohol, and a scratch printing ink having adhesion (adhesiveness) to the non-peeling layer (16) and quick drying property. can do.

Further, the conventional rubber-based printing ink for scratches uses toluene, xylene or the like as a solvent, and the Fire Service Law and the organic solvent poisoning prevention rule (Labor Safety and Sanitation Law)
It was unsuitable for in-line printing in an offset printing machine because of the large cost burden from the aspect of compliance with the above, but the styrene acrylic resin and / or urethane used in the printed material with the scratch masking layer of the present invention. A printing ink for scratches, which is made into an emulsion by dispersing a water-based resin as a binder in water and a small amount of isopropyl alcohol, is suitable for in-line printing on an offset printing machine in terms of compliance with the Fire Service Act and the Organic Law. It is a thing.

The base material (10) constituting the scratch concealment layer-attached printed matter (1) of the present invention includes, for example, instant lottery tickets, game cards, art paper, coated paper, or fine paper such as fine paper.

[0032]

Since the present invention has the above-mentioned constitution, it has the following effects. That is, a non-peelable layer having the same image as the confidential information data and an easy-peelable layer having the non-peelable layer as a non-image portion are provided on the base material so as to cover the non-peelable layer and the easy-peelable layer. In a printed material with a scratch masking layer, which is colored and has a solid scratch masking layer, the confidential information data is a scratch masked layer printed material composed of a scratch masking layer on a non-peeling layer that is not scratched off by scratching off. So in this sensitive data part,
Before scratching off, it is integrated with the scratch concealing layer on the easy peeling layer with the same thickness, so even if you give it a strong light and make a watermark, it will be difficult to see as confidential information data. Since it is not necessary to apply a watermark prevention layer on the back surface unlike the printed material with the scratch masking layer, the degree of freedom in designing the back surface is increased.
Since it does not require repeated printing or thick paper, it has an effect of reducing the manufacturing cost.

As described above, since the scratch concealing layer on the easily peelable layer is visually recognized as confidential information data,
The scratch masking layer is thickly formed as in the conventional case, and it is not necessary to increase the masking property, and the ink for forming the scratch masking layer may be a colored ink without increasing the amount of aluminum powder or the like that deteriorates printability, This printing method is also screen printing, for example, a gravure method with good production efficiency,
A roll coat method using a resin letterpress or a flexo method can be applied.

Further, the scratch concealment layer on the outermost surface is formed by forming the scratch concealment layer with, for example, regular lines or halftone dots or irregular ground pattern, fine pattern, or line drawing pattern such as line drawing pattern. It is possible to provide a printed material with a scratch concealing layer, which gives a degree of freedom to the layer design and is visually attractive.

Further, by forming the non-peelable layer and the easily peelable layer as colorless or light images (patterns) of the same color,
In particular, even when the scratch concealment layer has a regular or irregular line drawing pattern so that a part of the non-peelable layer and the easy-peelable layer can be seen, or even when seen through the watermark, the non-peelable layer and the easy-peelable layer. Since the boundary between the and confidential information is not visible, the confidential information data can be printed with a highly reliable scratch concealing layer that is not visible before scratching off, and the colored scratch concealing layer forms the confidential information data. When doing so, it is possible to obtain a contrast between the non-peelable layer and the easily peelable layer.

Furthermore, the scratch concealment layer is formed by a printing ink having a styrene-acrylic resin and / or a urethane resin as a binder and having excellent adhesion,
Since there was a large difference in the adhesiveness between the easily peelable layer and the non-peelable layer with respect to this scratch concealing layer, the adhesiveness with respect to the non-peelable layer was improved as a result, and when scratched off during use, the easily peelable layer easily scratched. It is turned off, but remains on the non-peeling layer without being scratched off, and the remaining portion is recognized as confidential information data, and the printing ink for the scratch concealing layer is the same as the conventional SB.
Compared to slow-drying inks that use synthetic rubber resins such as R and NBR as binders, they dry faster, so regular or irregular line drawing patterns such as lines, halftone dots, fine prints or line drawing patterns flow with leveling. Therefore, it is possible to provide a printed material with a scratch masking layer, which is excellent in sharpness and looks good in the design of the scratch masking layer on the outermost surface. Furthermore, since this scratch concealing layer ink is quick-drying, it forms a film without leveling, and the step at the boundary between the easily peelable layer and the non-peelable layer is not visually recognized as confidential information data on the surface of the scratch concealing layer, and It is possible to provide a printed material with a scratch masking layer that enables in-line printing on an offset printing machine.

Therefore, the present invention exerts an excellent practical effect as a printed material with a scratch masking layer in which confidential information data is masked by a scratch masking layer such as an instant lottery ticket or a game card.
