Abstract

PROBLEM TO BE SOLVED: To dispense with measures for enhancing hiding properties and countering light-transmitting properties, to enable prevention of the possibility that winning and failure are determined before the use, while making design properties unrestricted, and further to eliminate disadvantages in productivity and cost. SOLUTION: White capsule-containing ink is made by mixing therein dye capsules 1 coloring in blue, by 25%. The capsule-containing ink is applied on the surface of a base 2 to form a capsule layer 3 (A). Letters of 'winning' are printed on the capsule layer 3 by typographic printing by using color- developing ink which colors in the same white as the capsule-containing ink when printed, so that a color-developing printed part 4 be formed of the printed letters (B). When almost the whole surface of the capsule layer 3 whereon the color-developing printed part 4 is provided is scrubbed by a nail or a coin, the color-developing printed part 4 printed with the color-developing ink develops a color (blue) and appears [(C)] and the letters of 'winning' can be clearly ascertained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winning system or the like that expresses hidden printed characters and figures and awards a prize or a premium based on a result of comparison with predetermined characters or figures or the like. The present invention relates to a method for producing a scratch coloring body and a scratch coloring body.

[0002]

2. Description of the Related Art Conventionally, tickets used as services in speed lottery, fast food stores, and the like are manufactured by printing numbers and letters on a base material and then printing ink having concealment properties thereon. A concealing layer is formed so that the underlying print is not visible. Then, when the purchaser of the lottery or the person who receives the ticket scrapes the concealing layer using nails or coins, numbers, characters, and the like printed on the base appear. The number and characters that appear are compared with predetermined numbers and characters, and if they match, a winning is determined.

[0003]

However, since the numbers and characters printed on the background are important displays for determining the presence or absence of a win, they are often printed in a hue that is easy to judge. It is difficult to conceal. Therefore, in order to prevent the danger that the printed characters or the like can be read without peeling the concealing layer using the transmitted light, or that the result of the winning / losing can be determined before use, the following measures are taken. Have been. The concealing layer is made to have a low light transmittance such as black or aluminum paste, and the film thickness is increased to lower the light transmittance. A hue that makes it difficult to determine numbers, characters, and the like to be printed on the background. Light transmission is prevented by making the base material thick paper or by interposing an aluminum vapor deposition layer. Printing is performed on the back surface of the base material, in which characters indicating winning cannot be determined by light transmission.

[0004] However, printing a concealing layer having low light transmittance is greatly restricted in designability, and increasing the film thickness is limited in the printing method. Often disadvantageous. In addition, printing numbers, characters, and the like in a hue that is difficult to determine is not a desirable measure because a winning determination is likely to be erroneous. Further, making the substrate thick paper, interposing an aluminum vapor-deposited layer, or printing an interference pattern or the like on the back surface of the substrate has limited applications and disadvantages in terms of cost are inevitable.

The present invention has been made in view of such a conventional situation. The present invention makes it possible to improve the concealment property and eliminate the need for measures against light transmission, and to provide a product with a free design and free production. It is an object of the present invention to provide a method for manufacturing a scratch coloring body and a scratch coloring body which have no disadvantages in terms of performance and cost and can prevent the risk of winning / losing judgment before use.

[0006]

According to the present invention, there is provided a method for producing a scratch coloring body, comprising forming a capsule layer by coating a capsule containing a coloring dye on the surface of a substrate. At the same time, on the capsule layer, the color should be formed using a color developer which is indistinguishable from the capsule layer in a printed state and which develops color by contacting the dye with the destruction of the capsule. Perform predetermined printing of characters and figures. Alternatively, a processed substrate having a capsule layer formed in advance by coating a capsule containing a chromogenic dye on the surface of the substrate is prepared, and when the capsule layer is printed, it is indistinguishable from the capsule layer. A predetermined printing of characters, figures, and the like to be colored is performed by using a color developing agent which is capable of being colored upon contact with the dye in association with the destruction of the capsule. Further, the scratch coloring body according to the present invention includes a base material, a capsule layer formed by coating a capsule containing a color-forming dye on the surface of the base material, and a coated layer formed on the capsule layer. It comprises a predetermined printing portion of characters and graphics to be colored, which is printed using a color developing agent which is indistinguishable from the capsule layer and which comes into contact with the dye upon destruction of the capsule and which develops a color when contacted with the dye.

That is, the present invention comprises a combination of a capsule layer formed by coating a capsule containing a coloring dye and a developer layer formed by printing a developing agent which forms a color upon contact with the dye. However, these layers may be coated or printed to a thickness that is sufficient for the determination.

As a coating method for coating a capsule containing a coloring dye, a mixture of the capsule and a binder as a binder, a water-soluble polymer such as polyvinyl alcohol or soluble starch, or a latex such as styrene-butadiene is coated on paper with an air knife. A method of coating with a coater can be used.

The capsule layer serving as the lower layer is made of a resin which forms a film exhibiting an adhesive property which is difficult to peel off from a capsule containing a leuco dye, a liquid for dissolving the leuco dye and a base material by a frictional force from the outside. Pigments and the like can be added accordingly.

[0010] The developer is applied in a predetermined printing of characters, figures, and the like to be colored, using a developer that develops color when it comes into contact with the dye as the capsule is destroyed. Further, it is necessary that the developer is first indistinguishable from the capsule layer in a printed state, and secondly, it is required to be colored by contacting the dye with the destruction of the capsule. is there. Since the developer is indistinguishable from the capsule layer in a printed state, a predetermined print of a character or a figure to be colored is not seen before coloring.

When a leuco dye is used as a dye for the capsule layer, a normal developer ink is used, and a developer such as acid clay, a phenol resin or a salicylic acid derivative, a pigment and a pigment are used. A heat or light curable ink composed of a vehicle is also used.

These compositions are printed on a substrate by adopting a printing method, such as letterpress, offset, gravure, flexo, screen printing or the like, as necessary, which is most suitable for the composition.

[0013] When the entire surface of the capsule layer is rubbed with a nail or a coin during use, the capsule is destroyed by the friction, and the liquid containing the coloring dye therein oozes out. Then, in the portion where the color developer is printed on the capsule layer, the color-forming dye comes into contact with the color developer to form a color. As a result, a predetermined printed portion of a character or a figure, etc., which has been printed in advance with a color developing agent, becomes visible, and the predetermined printed portion of a character, a figure, or the like can be visually observed.

[0014]

The present invention will be described below in detail with reference to examples. Example 1 (see FIG. 1) 25% of a blue-colored dye capsule 1 was mixed with a styrene-butadiene latex containing a white pigment to produce a white capsule-containing ink. This capsule-containing ink was coated on the surface of a base material 2 made of coated paper of 70 Kg by a coater with an air knife to form a capsule layer 3 (FIG. 1A).

Next, when printed on the capsule layer 3, the letterpress OT No. manufactured by Teikoku Ink Mfg. Co., Ltd. becomes the same white color as the capsule-containing ink. Using 3 color inks,
By performing letter printing of “Atari” by letterpress printing, a developed color printing section 4 composed of letter printing is formed, and a scratch coloring body 5 is formed.
[FIG. (B)].

The color-developed printing section 4 using a color developer is white,
The finished scratch coloring body 5 was illuminated from behind in a dark place to check the printed characters, but could not confirm it at all. Unexpected color formation due to the destruction of the dye capsule 1 did not occur.

When the entire surface of the capsule layer 3 provided with the developed color printing portion 4 is rubbed with a nail and a coin, the developed color printing portion 4 printed with the developed ink develops a color other than white. (Blue color development) and emerged [FIG. (C)], and the character of “Atari” was clearly identified. In addition, there was no peeling of the capsule layer 3 from the base material 2 and no peeling of the developed color printing portion 4 from the capsule layer 3 at the time of friction, and the fixability of the capsule layer 3 and the developed color printing portion 4 was also confirmed.

Example 2 (See FIG. 1) Aqueous screen ink manufactured by Teikoku Ink Manufacturing Co., Ltd., Cericol Aqua RUB-488 white was mixed with 25% of a black color dye capsule 1 to prepare a white capsule-containing ink. Generated. This capsule-containing ink was coated on the surface of a base material 2 made of high-quality paper of 70 kg using a bar coater to form a capsule layer 3 (FIG. 1A).

Next, using the Technos UVEX1 developer ink of Teikoku Ink Mfg. Co., Ltd., which becomes the same white color as the capsule-containing ink when printed on the capsule layer 3,
Perform "Atari" character printing by offset printing,
A developed color printing section 4 composed of character printing was formed, and a scratch coloring body 5 was obtained [FIG. At this time, the printed matter was dried and cured by an ultraviolet lamp because this ink was an ultraviolet curing type ink.

The color-developed printing section 4 using a color developer is white,
The finished scratch coloring body 5 was illuminated from behind in a dark place to check the printed characters, but could not confirm it at all. Unexpected color formation due to the destruction of the dye capsule 1 did not occur.

Then, when almost the entire surface of the capsule layer 3 provided with the developed color printing portion 4 was rubbed with a nail and a coin, the developed color printing portion 4 printed with the developed ink developed a color other than white. (Color development in black) and emerged [FIG. (C)], and the character of “Atari” was clearly identified. In addition, there was no peeling of the capsule layer 3 from the base material 2 and no peeling of the developed color printing portion 4 from the capsule layer 3 at the time of friction, and the fixability of the capsule layer 3 and the developed color printing portion 4 was also confirmed.

Embodiment 3 (See FIG. 2) FIG. 2 shows Embodiment 3 of the present invention. In Embodiment 3 shown in FIG. 2, the steps (A) and (B) are the same as those described above. This is the same as Example 1 or Example 2 described above. Then, in the step (B) ′, a top coat layer 6 was further formed of a transparent resin on the capsule layer 3 on which the developed color printing portion 4 was formed.

When the entire surface of the top coat layer 6 is rubbed with a nail and a coin, the developed color printed portion 4 printed with the developed ink develops a color other than white (blue color development) and emerges. [(C) in the figure], the character of "Atari" could be clearly identified. In addition, there was no peeling of the capsule layer 3 from the base material 2 and no peeling of the developed color portion 4 from the capsule layer 3 at the time of friction, and the fixability of the capsule layer 3 and the developed color portion 4 was confirmed.

That is, as shown in each of Examples 1 to 3, the conventional scratch ink needs to have a hiding property, so that a black color is printed on the back surface of the printed material with a hue close to silver and aluminum or the like. While the use of paper to which a foil was attached was common, the use of ordinary coated paper or high-quality paper allowed the creation of a scratch colored body that could achieve the same purpose.

In each embodiment, the surface of the substrate 2 is coated with the capsule-containing ink to form the capsule layer 3, but the capsule layer 3 is formed on the surface of the substrate 2 in advance. The developed printed portion 4 may be formed by printing on the capsule layer 3 of the processed base material using the processed base material.

[0026]

As described above, according to the present invention, since it is not necessary to hide the expressed numbers and characters,
It is not necessary to increase the concealing property or take measures against light transmittance, and as a result, it is possible to secure the degree of freedom in design,
It is possible to eliminate disadvantages in terms of productivity and cost, and further completely prevent the risk of winning / losing judgment before manifestation. Further, since it is not necessary to scrape off the concealing layer using nails or coins as in the related art, the concealing layer can be used without generating dust and scum due to the shading off the concealing layer.
