Description

  The present invention relates to a printed matter with a scratch concealment layer in which a valuable information printing unit such as a lottery ticket is concealed with a scratch concealment layer, and more specifically, the scratch concealment layer is scratched off with a coin or the like (scratch off) to print valuable information. The present invention relates to a printed matter with a scratch concealment layer that is difficult to steal a valuable information printing part before recognizing the part.

  In the present specification, “ratio”, “part”, “%” and the like indicating the composition are based on mass unless otherwise specified, and the “/” mark indicates that they are integrally laminated.

  (Background Art) A printed matter with a scratch concealment layer scrapes off the concealment scratch concealment layer with a coin or the like, and can visually recognize and recognize a valuable information printing part such as a character or a pattern on the base. For example, in lottery tickets and game cards, the valuable information printing section such as “win”, “off”, or the corresponding pattern is concealed with a scratch concealment layer that has concealability and scratch-off (ease of scratching). ing. And the purchased customer scratches off with a coin etc. at the time of use, and visually recognizes a valuable information printing part. As described above, in the printed matter with the scratch concealment layer, the valuable information printing part is concealed by the scratch concealing layer having the concealing property and the scratching property. There was a drawback that it was seen through and so-called stolen. For this purpose, the following proposals have been made. (1) Although the method using special paper sandwiching light-impermeable aluminum can prevent snooping, it requires an extra material called aluminum and its lamination, which requires a complicated manufacturing method, long delivery time, and high cost. There is a problem. (2) The method of overprinting the ink having scratch properties to increase the concealment property has the problems that an ink cost and a printing process are required, resulting in a long delivery time and high cost. (3) In the method of adding a concealing layer on the opposite surface of the valuable information printing section, there are problems that an ink cost and a printing process are required, and that a long delivery time and high cost are required. (4) In the method of printing a tint block pattern on ink having scratch properties, there are problems that an ink fee, a plate making fee, and a printing process are required, resulting in a long delivery time and high cost.

  Therefore, the printed matter with the scratch concealment layer is difficult to see because the valuable information printing part is difficult to see through before scratch-off, and as the concealment scratch concealment layer, the scratch concealment layer can be thinned, and the overprinting of the scratch concealment layer can be reduced, In addition, it is possible to use scratch concealment for offset that is inexpensive and transparent, and there is little fear of being scratched even when manufacturing and distributing printed matter with a scratch concealment layer, and it is required to be manufactured inexpensively with existing equipment and technology .

  (Prior Art) Conventionally, a scratch printed matter (corresponding to a printed matter with a scratch concealment layer of the present application) is provided with a peelable concealment information layer 12 printed on a surface of a base sheet 11 using a transparent release agent, It is known that a concealing information layer 12 (Claim 2; printed by an electrostatic printing method using a transparent release agent made of a non-magnetic one-component toner) is provided with a coloring layer 13 made of a coloring ink covering from above. (For example, refer to Patent Document 1). However, since non-magnetic one-component toner is used and printing is performed by an electrostatic printing method, there is a disadvantage that high cost and dedicated equipment are required.

  Further, the printed matter with a scratch concealment layer is a printed matter with a scratch concealment layer in which the valuable information printing part is concealed with an ink having a scratch property on a sheet-like base material, which is either a part or the whole of the valuable information printing part. At least a forgery prevention layer (Claim 2: thermal ink or temperature ink), (Claim 3: functional ink including infrared absorbing ink) is known (for example, patent) Reference 2). However, the use of heat-sensitive ink, temperature ink, and infrared absorption ink is expensive, and prevention of forgery and counterfeiting is a problem, and no description or suggestion has been made regarding snooping.

  Further, the scratch-off ticket (corresponding to the printed matter with the scratch concealment layer of the present application) is provided with a lottery pattern such as letters, numbers, patterns, etc., on which a base picture portion is hit and displays a loss, A ticket provided with a concealing layer so as to cover the lottery pattern, wherein the underlying pattern portion and the lottery pattern are printed with ultraviolet curable (UV) ink, and the concealing layer (Claim 4; PCS concentration 0.9) It is known that the above is printed with an oily black process ink (Claim 2; black UV ink) (for example, see Patent Document 3). However, the adhesiveness between the two layers using high-cost UV ink is low, and the scratching property ensures the scratching property, and the prevention of snooping requires an overly concealing hiding layer with a PCS concentration of 0.9 or more. There is a problem of doing.

  Furthermore, the applicant of the present invention has a secret information display portion on which the secret information is displayed on the upper surface of the base sheet using a printer, and is formed on at least the secret information display portion, and has a concealing property for the base and is scratched. Disclosed is a printed matter with a scratch concealment layer, comprising a possible scratch concealment layer and a fusion print layer formed on the lower surface of the base sheet and making it difficult to read the secret information by light transmission from below the base sheet (For example, refer to Patent Document 4). However, since printing is performed on both sides of the base material, the printing process is many and expensive, and the fused printing layer is described only as a fused printing layer that makes it difficult to read the secret information by light transmission. By making the light transmission density 3.6 in the harmony printed layer / base sheet / protective layer / scratch concealing layer, almost no light is transmitted, so that it is impossible to illegally see through the back side. It is. The layer structure is different from the base material 11 / value information printing part 21 / transparent peeling layer 13 / hiding scratch hiding layer 15B / hiding character part 23 / hiding scratch hiding layer 15A of the present invention. Further, in Patent Document 4, it is difficult to interpret the secret information by light transmission by means of a unified printing layer (corresponding to the concealed character portion 23 of the present application). What is the technical idea of solid printing that does not have the concealed character portion 23 that is a limited character pattern of the present invention, and that the information of the valuable information printing portion 21 is camouflaged by the concealed character portion 23 to make it difficult to read? Is different.

  In order to solve the above-described problems, the present inventors have made extensive studies and have completed the present invention. Its purpose is that it is difficult to see through the valuable information printing section before scratch-off, and it is difficult to see, and as a concealing scratch concealing layer, the scratch concealment layer can be made thin, overprinting of the scratch concealment layer can be reduced, and it is inexpensive. It is possible to use scratch concealment for offset that is easy to see through, there is less concern about being scratched by manufacturing and distribution of printed matter with a scratch concealment layer, and by providing a printed matter with a scratch concealment layer that can be manufactured inexpensively with existing equipment and technology is there.

In order to solve the above problems, a printed material 10 with a scratch concealment layer according to the invention of claim 1 of the present invention includes a base material 11, a valuable information printing unit 21 on one surface of the base material 11, and a transparent material. The peelable layer 13, the concealing scratch concealing layer 15 B, the concealing character part 23, and the concealing scratch concealing layer 15 A, the valuable information printing part 21 and the concealing character part 23 are provided at the overlapping positions, and the valuable The information printing unit 21 is a number and / or alphabet character string,
The concealed character portion 23 is a character string of characters in which all numerals are superimposed and / or characters in which all alphabets are overlapped, and the density difference between the valuable information printing portion 21 and the concealed character portion 23 is JIS- The PCS value measured by X-0501 is 0.2 or more, and the valuable information printing part 21 is not concealed by the concealment character part 23 even if the printed matter 10 with the scratch concealment layer is watermarked. This is a printed matter with a scratch concealing layer.

  The printed matter 10 with a scratch concealment layer according to the invention of claim 2 is characterized in that the valuable information printing part 21 has a red color tone and the concealed character part 23 has a black color tone. This is a printed material 10 with a scratch concealing layer.

  According to the first aspect of the present invention, since the valuable information printing unit 21 is not easily seen through before scratch-off, it is difficult to see and the concealing scratch concealing layers 15A and 15B can be thinned, and the scratch concealing layers 15A and 15B are overprinted. In addition, the scratch concealment layers 15A and 15B can be formed using a cheap and transparent offset scratch concealment ink, and there is little fear of being scratched by the manufacture or distribution of the printed material 10 with the scratch concealment layer. It produces the effect of manufacturing at low cost with the equipment and technology.

  According to the second aspect of the present invention, in addition to the effect of the first aspect, there is an effect that the valuable information printing unit 21 is more difficult to see through and is not easily seen before the scratch-off.

It is sectional drawing of the printed matter with a scratch concealment layer which shows one Example of this invention. It is sectional drawing of the printed matter with a scratch concealment layer which shows one Example of this invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  (Printed matter with scratch concealment layer) As shown in FIG. 1, the printed matter 10 with a scratch concealment layer of the present invention comprises a base material 11 and a valuable information printing part 21 on one surface of the base material 11, a transparent release layer. 13. A concealing scratch concealment layer 15B, a concealment character portion 23, and a concealment scratch concealment layer 15A are provided. The valuable information printing unit 21 is a number and / or alphabet character string, and the concealed character unit 23 is a character pattern in which all numbers are superimposed and / or a character in a character pattern in which all alphabets are superimposed. The valuable information printing part 21 and the concealed character part 23 are provided in a position where they overlap each other, and the density difference between the valuable information printing part 21 and the concealed character part 23 is the difference in PCS values measured according to JIS-X-0501. And 0.2 or more. By doing so, the valuable information printing unit 21 is concealed by the concealment character unit 23 and is not easily seen through even when the printed matter with the scratch concealment layer is watermarked with light. The concealment in this case includes not only simple concealment that does not transmit light, but also includes an effect of camouflaging the valuable information printing unit 21 with a character pattern in which all numerals and / or alphabets are superimposed. 21 is more difficult to see and therefore difficult to recognize. Further, as shown in FIG. 2, the concealing scratch concealment layer 15B may not be provided, and the concealment scratch concealment layers 15A and 15B may be formed of a plurality of layers by overprinting.

  (Effect) According to the present invention, the following effects can be obtained. (1) Since the valuable information printing unit 21 is not easily seen through before the scratch-off, the printed matter 10 with the scratch concealment layer is not easily seen and the information of the valuable information printing unit 21 is difficult to read. Even if the valuable information printing unit 21 is slightly seen through, it is camouflaged because it is included in the character pattern of the concealed character unit 23, and the information of the valuable information printing unit 21 is extremely difficult to read. (2) Further, since the valuable information printing part 21 is concealed by the concealment character part 23 and is not easily seen through, the thickness of the scratch concealment layer can be reduced as the concealment scratch concealment layers 15A and 15B. There is less concern that the printed matter 10 with a layer may be scraped even when a protrusion is caught on the surface even when the printed product 10 is distributed or distributed. (3) Furthermore, since the valuable information printing unit 21 is not easily seen through, overprinting of the scratch concealment layers 15A and 15B can be reduced. (4) Moreover, as the scratch concealment layers 15A and 15B, an inexpensive scratch concealment ink for offsetting can be used. (5) Furthermore, it can be mass-produced inexpensively with existing equipment and technology.

  (Substrate) The substrate 11 is not particularly limited, and may be appropriately selected depending on the purpose of use. For example, paper such as high-quality paper, medium-quality paper, coated paper, ivory paper, postcard, double-sided card paper, Manila cardboard, white ball, etc., and these papers are water and oil resistant as required. , Heat resistance, chemical resistance, etc. may be imparted. In addition, for example, resinous films such as polypropylene, polyethylene terephthalate, acrylic resin, and cellulose resin can be used.

  (Valuable Information Printing Unit) The valuable information printing unit 21 is printed on one surface of the substrate 11. The printing of the valuable information printing unit 21 is not particularly limited. For example, it is a known printing method such as gravure printing, offset printing, letterpress printing, ink jet printing, flexographic printing, screen printing, and the like. Print it out. The valuable information printing unit 21 is an information unit that is difficult to see through before scratch-off, and is a character string of numerals and / or alphabets.

  (Peeling layer) The peeling layer 13 is printed on the surface of the valuable information printing unit 21. As the transparent release layer 13, for example, a release cloth (ink) in which an additive such as silicone or polyethylene wax is added to polyurethane / acrylic resin, polyamide resin, or nitrocellulose resin as required. It may be used by printing by a known printing method such as gravure printing, screen printing, ink jet printing, etc., and may be dried as necessary to form a thickness of 2 to 10 μm.

  (Scratch masking layer) The scratch masking layer 15B is printed on the surface of the transparent release layer 13. The scratch concealment layers 15A and 15B have the same performance, and may be the same composition or different ones. The scratch concealment layers 15A and 15B will be described as the scratch concealment layer 15 together for explanation.

  The scratch concealment layer 15 is a layer having both concealment and scratch properties. As the scratch concealment layer 15, natural rubber resins such as cohesive fracture natural rubber and hydrochloric acid rubber, polybutadiene, styrene, butadiene copolymer, acrylonitrile / butadiene copolymer, polyisoprene, polychloroprene and other dienes are used. 40 to 60% by mass of a metallic fine powder such as aluminum powder, brass fine powder, copper fine powder, or oxidized fine powder thereof as a colorant is added to a resin based on acrylic, acrylic or vinyl. You may add an additive to these as needed.

  The above composition is diluted with a solvent and applied to a coating method such as screen printing or gravure printing, or a coating method such as roll coater, gravure coater, comma coater, etc. to form a thickness of 3 to 15 μm. That's fine.

  (Hidden character portion) The hidden character portion 23 is printed on the surface of the scratch concealment layer 15B. When the scratch concealment layer 15B is not provided, the concealment character portion 23 is printed on the surface of the release layer 13. Printing of the concealed character portion 23 and ink may be the same as the printing of the valuable information printing portion 21. The concealed character portion 23 is a character string in which all numbers are superimposed and / or a character string in which all alphabets are superimposed.

  (Sneak peek) The valuable information printing unit 21 is a number and / or alphabet character string, and the concealing character unit 23 is a character pattern in which all numbers are superimposed and / or a character pattern in which all alphabets are superimposed. A column. Further, for example, if the valuable information printing unit 21 sets the digitally marked numeric Atari No., “8” becomes the concealed character of the concealed character unit 23 and is hidden from the Atari No. as shown in FIG. Because the letters are visible, it is difficult to see through. When the valuable information printing unit 21 is composed only of numbers, it is effective to simply print “8” as the dummy No. that becomes the concealed character of the concealed character unit 23. Further, in order to easily conceal the information in the valuable information printing unit 21, it is preferable to make the concealed character of the concealed character unit 23 thicker. In this way, even if light is watermarked on the printed material 10 with the scratch concealment layer, the concealed character portion 23 can be seen more easily than the valuable information print portion 21, and the information is difficult to read.

  The optical characteristics of the (PCS) barcode are defined in JIS-X-0501 as a PCS value (Print Contrast Signal) is defined and the PCS value must be a certain value or more. ing. The PCS value is the reflection of the white bar and the margin when illuminated at a 45 ° incidence angle of the A light source defined in JIS-Z-8720 with respect to the normal of the barcode symbol surface of the barcode. It is calculated from the rate and the reflectance of the black bar. When the reflectance of the white bar and the margin is RL and the reflectance of the black bar is R0, it is defined as PCS value = (RL−R0) / RL. The PCS value is a reference for reading a barcode frequently used for merchandise management with a reading device (barcode reader), and the PCS value is cited as the readability of the display. The higher the contrast between the white bar (background) and the black bar (display unit) of the barcode, the easier it is to read with the barcode reader.

JIS-X-0501 defines the minimum PCS value required as a bar code symbol for common products as a function of white bar reflectance. Moreover, in this specification, as a measurement of PCS value, it measured by a measurement with A filter using the reflection densitometer Macbeth PCM-2 machine (made by Macbeth, brand name). The difference in density between the valuable information printing part 21 and the concealed character part 23 of the printed matter 10 with the scratch concealment layer is set to 0.2 or more as the difference in PCS values measured according to JIS-X-0501. In this way, by setting the PCS value difference to be 0.2 or more, the valuable information printing unit 21 is concealed by the concealed character unit 23 and is not easily seen through, and is further camouflaged by the concealed character unit 23 so that the perspective is more visible It is difficult to read information.

  (Character Color) In the printed matter 10 with the scratch concealment layer, the valuable information printing unit 21 preferably has a red color tone, and the concealed character portion 23 preferably has a black color tone. Since it is easy to conceal by setting the ink color tone of the concealment character portion 23, it is difficult to see through and information is difficult to read. For example, as shown in Table 1, combination number No1 is a combination of black numbers and black numbers 8; combination number No2 is a combination of light pink numbers and black numbers 8; and combination number No3 is a combination of light purple numbers Combination of black number 8 columns, combination number No4 is a combination of pink number columns and black number 8 columns, combination number No5 is a combination of thin black number columns and black number 8 columns, combination number No6 is a black number sequence (value The information printing unit 21) was combined with black solid printing (the concealed character portion 23) covering the black numeral string.

これらのスクラッチ隠蔽層付き印刷物１０のスクラッチ隠蔽層１５Ａ面から、強い光をあてて、光を透しにくい筒状物を介して、肉眼で観察した。その結果も表１へ併記する。

From the surface of the scratch concealment layer 15A of the printed material 10 with the scratch concealment layer, strong light was applied and observed with the naked eye through a cylindrical object that was difficult to transmit light. The results are also shown in Table 1.

  The combination number No. 6 could be interpreted, and even the combination numbers No. 1 and 5 were observed with a fluoroscopic image. Even in combination No. 4, a fluoroscopic image was observed, and there was a possibility that it could be read although it was a plurality of candidates. However, combination numbers No. 2 and 3 could not be read. Thus, the effect of showing the concealed character-like pattern as the concealed character portion 23 which is another combination was higher than the black solid shape of the concealed character portion 23 of the combination number No6.

  By overprinting the scratch concealment layers 15A and 15B, the concealability can be further enhanced. However, since it is more effective to show the concealed character-like pattern that is the concealed character portion 23, the overprinting of the scratch concealment layers 15A and 15B can be reduced, and it can be finished at a low cost. In addition, since it is harder to see through and it is difficult to read information when the concealed character pattern that is the concealed character portion 23 is shown, it is possible to use an inexpensive and easy-to-see offset ink having scratch properties, and the scratch concealing layers 15A and 15B. Since the thickness can be reduced, there is also an effect that there is less fear of being scraped even when a printed matter 10 with a scratch concealing layer is produced, distributed or even if a projection is caught on the surface.
