Description

  The present invention is a lottery ticket or lottery ticket affixed to a lottery ticket, lottery ticket, game card, etc., etc. Information (hereinafter referred to as individual image information) is related to an image information recording medium concealed by a scratch concealment layer. In particular, the scratch concealment layer is scraped with a coin or the like so that the individual image information can be made visible. The present invention relates to an image information recording medium capable of repeating visible and invisible individual image information.

  Conventionally, it is known that individual image information consisting of winning numbers, winnings, grades, etc. that are not wanted to be known by other persons concerned, or images (pictures) corresponding to them are recorded, such as lottery tickets, lottery tickets, game cards, Alternatively, there is an image information recording medium used for an ID card, membership card, prepaid card, etc. for proving identity. These image information recording media are designed to prevent the counterfeiting and falsification by making it possible to confirm the contents of these information only when necessary, or making it difficult to obtain copies. It is also various from the viewpoint of, and is used in various fields.

  Among various measures such as anti-counterfeiting, there are measures against illegal copying and forgery using a copying machine. For example, individual image information such as winning of image information recording media such as lottery tickets and ID cards is encrypted, and this encryption is performed. There is a method of recording with a light-colored information recording material so that it cannot be faithfully reproduced even if the digitized information is copied.

  However, the above-described method of recording with the light information recording material has a drawback that it is very difficult to recognize the individual image information that appears when the encrypted information is superimposed and decrypted. In addition, when decoding desired individual image information, registration is performed with register marks such as register marks provided on the periphery. However, since the color of the register marks is light, there is a disadvantage that registration is difficult. Furthermore, if the sensitivity of the copier is standard, the copy will be lighter than the original and will be recognized as a copy, but by increasing the sensitivity, it will be reproduced in a darker color. There was a problem that it would be very close to the real thing.

  As another countermeasure against illegal copying and forgery using the above-mentioned copying machine, the pixel size constituting the encrypted individual image information is made smaller than the size that can be reproduced by the copying machine, and the aggregate is encrypted. There is a technology that prevents information from being reproduced and reproduced. However, in such a technique, since the pixels constituting the encrypted information are very small, the color of the encrypted information that is a collection of them becomes thin as a whole, and the encrypted information is overlaid with the registration in mind. There is a drawback that it is very difficult to recognize the individual image information that will sometimes be restored.

  In addition, there is an image information recording medium having encrypted information that can be combined and recognized as desired individual information when superimposed. This is because encrypted information is formed in a plurality of encrypted information forming units that are arranged apart from a part of the base material, the base materials are separated, and the separated base materials are encrypted. If the information forming unit is overlapped so that the information is restored, the encryption forming unit restores the desired individual image information so that the individual information can be seen only when necessary. .

However, when the registrations of these encryption forming units are aligned, the desired individual image information is decrypted and can be viewed as many times as necessary.
Because it is not compounded, it takes a lot of time to align the register, and if an unfamiliar person tries to align, the orientation and front and back etc. are mistakenly overlapped, and the individual image information of the encryption cannot be visually recognized, or There is a problem that it becomes difficult to visually recognize and it takes a lot of time until it becomes visible.

  Furthermore, as another example, for example, in an image information recording medium provided with a scratch masking layer, the easily peelable layer has a regular line pattern, and the scratch masking layer remaining after the scratch masking layer is removed. And confidential information data (individual image information that is not desired to be known to anyone other than those involved), there is an image information recording medium in which encryption is decrypted (see, for example, Patent Document 1).

  However, when the confidential information data (individual image information) and the pattern of the easily peelable layer are fine, it is difficult to register, and conversely, if the pattern is rough, the data (individual information) becomes easy to see, and the scratch concealment is performed. If the layer is scraped (scratch off), the individual image information can be visually recognized, but once the scratch concealment layer is scraped, the individual information that was the latent image cannot be repeatedly visible and invisible, so There was a problem that there was a high possibility of being known.

The above prior art documents are shown below.

FIG. 14 is a plan view showing desired individual image information “1234” when the first image 21 and the second image 22 are combined. Further, FIG. 1D is a diagram when the individual image information is no longer visible to anyone other than the concerned person, so that the upper base material is removed and the individual image information becomes invisible.

  FIG. 4 which is a side sectional view taken along line YY in FIGS. 3A, 3B and 3A shows another embodiment of the image information recording medium 1 of the present invention. The first image 21 is provided on one of the base materials 11, and an easy-peeling layer 14 is provided to protect the first image 21 and to make it easy to scrape the upper scratch concealing layer 15, and the scratch concealment is provided thereon. The layer 15 is provided, the second image 22 is provided on the other transparent base material 12, and the end portions of the two base materials 11 and 12 are bonded together with the adhesive layer 16.

  FIG. 5 shows an embodiment of the image information medium 1 according to the present invention, in which FIG. 5 (a) shows the first image 21 and the second image 22 after the scratch concealment layer is removed. FIG. 5B is a plan view of the image information medium 1 when the individual image information 23 “1234” appears, FIG. 5B is an enlarged view of the first image 21, and FIG. FIG. 5D and FIG. 5E are explanatory views in which the image when the individual image information 23 appears by overlapping the first image and the second image is enlarged.

  Hereinafter, the material and forming method of each layer constituting the image information recording medium 1 of the present invention will be specifically described.

  First, as the base material 11, for example, art paper, coated paper, or high-quality paper, western paper such as art paper, coated paper, or high-quality paper, paperboard such as coated ball, court manila, double-sided card, or special securities Examples include paper and the like, and also white PET and white PVC sheets, which can be appropriately selected according to the application. In addition, the transparent substrate 12 is not particularly limited, and may be any transparent material such as transparent PET or transparent PVC sheet.

  Further, the concealing layer 13 is for preventing the transparent material from being seen from below when the base material is transparent or the base material is thin, and the concealing layer 13, the first image 21, and the second image 22 are vinyl-based. The gravure printing ink offset printing ink, the normal printing ink such as the offset printing ink and the screen printing ink can be formed.

  The individual image information 23 formed by combining the first image 21 and the second image 22 is one or more different pieces of image information. For example, as disclosed in JP-A-2001-213042, A method of dividing into two pieces of image information is used so that a regular or irregular line pattern pattern intersects.

  For example, as shown in FIG. 5B, the first image 21 is composed of parallel straight lines having the same line width as the normal print image, and as shown in FIG. 5C, the second image 22 is the first image. The first image 21 and the second image 22 are overlapped with each other, which is composed of a parallel line pattern composed of parallel straight lines in which parallel straight lines having the same line width as the straight lines are arranged at the same pitch (equal interval) as the line width. Then, as shown in FIGS. 5D and 5E, the individual image information 23 appears. In these line patterns, the boundary line 24 is formed by shifting the pitch phase of the parallel straight lines (line lines) of the inner area and the outer area of the individual image information 23 by a half pitch along the boundary corresponding part of both areas. Has been.

  As described above, when the first image 21 and the second image 22 are overlapped, the inner area and the outer area of the latent image pattern portion of the first image 21 are shifted by a half pitch. A portion that overlaps and a portion that does not overlap each other occur on the parallel lines and the parallel lines of the first image 21 that are shifted by a half pitch between the inner region and the outer region of the latent image pattern.

  As a result, for example, if the line of the first image 21 is a line forming the area where the individual image information 23 is formed, the line passes through the transparent portion between the lines of the second image 22. Then, as shown in FIG. 5D, the individual image information 23 is visualized and observed as a positive image.

  On the other hand, for example, if the line of the first image 21 that does not overlap the line of the second image 22 is a line that forms outside the area of the individual image information 23, that line is the line of the second image 22. It is visually observed through the transparent portion between the lines, and as shown in FIG. 5E, the individual image information 23 is visualized and observed as a negative image.

  The parallel straight lines (line lines) constituting the line pattern of the first image 21 have a fine line width that is thin enough not to interfere with the print design of the normal print image, and the inner side of the line pattern. The lines of the latent image line pattern formed in the area are only shifted in pitch phase with respect to the lines in the outer area, and the lines are fine. Specifically, nothing is visually observed as an image (apparently), and only a normal print image, that is, the first image 21 is observed.

  Further, as the first image 21 and the second image 22 forming the individual image information 23, a line pattern is an example, and each shape is a straight line, a broken line, a curved line, a square dot, a round dot. Shape, mesh dot shape, lattice dot shape, or a combination thereof. Furthermore, the present invention is not limited to lines or dots, and the individual image information 23 is not found in only one of the first image 21 or the second image 22, and the individual image information can be obtained by superimposing both images. Anything can be used as long as 23 can be determined.

  Further, the easy peeling layer 14 constituting the image information recording medium 1 of the present invention is for protecting the first image 21 and facilitating scratch-off of the scratch concealing layer 15, and various synthetic resins can be used. . For example, confidential information can be obtained by screen printing, gravure printing, or flexographic printing using an ink containing 5% by weight or less of silicon or wax (polyethylene wax, etc.) as an additive to polyurethane acrylic resin, polyamide resin, or nitrocellulose resin. Print to cover. In addition, a UV peeling varnish in which silicon or wax is slightly added to the medium of the ultraviolet curable offset ink can also be used.

  Further, the scratch concealment layer 15 is a concealment layer that conceals part or all of the first image 21, and has low adhesion to the easily peelable layer 14 on the first image 21. Add 20-30% of metal powder such as aluminum powder (silver), brass powder (gold), copper powder (red) as a concealing pigment in a resin binder in which a brittle resin that is easy to coagulate is dissolved in a solvent. Or a mixture of white extender pigments or dyes such as talc, kaolin, barium sulfate, calcium carbonate, and titanium oxide can be used. As the resin that easily aggregates, a resin in which different kinds of resins are mixed at an appropriate blending ratio can be used. For example, polyethylene, acrylic resin, vinyl resin, ethylene-vinyl acetate copolymer, polypropylene, polystyrene, styrene Polymer, styrene-butadiene rubber, polybutadiene, acrylonitrile-butadiene copolymer, polyisoprene, polychloroprene, natural rubber, chlorinated rubber, various waxes, rosin, terpene resin, terpene polymer, etc. A resin in which two or more kinds are blended in an appropriate ratio can be used. Solvents dissolved in this resin include toluene, methyl ethyl ketone, methyl isobutyl ketone, xylene, cyclohexanol, isobutyl acetate, cyclohexane, methyl cyclohexane, ethylene glycol mono Glycol derivatives such as Chirueteru or mixed solvent thereof, can be used.

  Furthermore, if necessary, a pattern printing layer on which characters or patterns are printed can be formed on the scratch concealment layer 15, and an image is formed with a transfer foil or hologram foil of gold or silver. You can also. This is because, after confirming the information concealed by scratching, if an attempt is made to forge the pre-scratch state by applying a paint or the like, printing of characters or designs on the scratch concealment layer 15 must also be restored. Therefore, counterfeiting becomes more complicated and unauthorized use can be prevented.

  Finally, a protective layer can be formed on top of these pattern printing layers as needed. For example, resins such as acrylic resin, vinyl chloride resin, polyester resin, and nitrocellulose are dissolved in a solvent such as toluene and xylene. The coating liquid is formed to a thickness of about 1 to 3 μm by using a gravure printing method, a screen printing method, a roll coating method, a knife edge method or the like coating or printing method.

  Specific examples of the present invention will be described below.

A masking layer is provided on half of a 38 μm thick PET base material, and a first image is printed thereon by an offset printing method. On top of that, an ethylene-based wax is used to protect the first image and to easily scrape the scratch masking layer. An easy peeling layer was formed by a gravure method. Next, an about 10 μm scratch concealing layer was formed by screen printing using an ink having the following composition. Further, a transparent protective layer was applied thereon so as to cover the entire surface of the scratch concealing layer portion.

[Ink composition of scratch concealment layer]
Aluminum powder 20-30wt%
SBR 26-30wt%
Solvent (Toluene / IPA / Methyl Cellosolve) 40-45wt%
Additive 4-5wt%
After the second image is printed by the offset printing method in a region different from the region where the printing is performed, that is, the other half of the PET base material, the second image is folded so as to overlap with the one formed with the scratch concealing layer. An image information recording medium of the present invention was obtained.

  The first image is printed on a 38 μm thick PET substrate by the offset printing method, and an easy-peeling layer of ethylene-based wax is formed by gravure method on the first image to make it easier to protect the first image and scratch the concealing layer. did. Next, the same ink composition as that of the scratch masking layer of Example 1 was used, and a scratch masking layer of about 10 μm was formed by screen printing. Further, a transparent protective layer was applied thereon so as to cover the entire surface of the scratch concealing layer portion.

  After printing the second image on a different 38 μm transparent substrate by the offset printing method, an adhesive is applied to a part of the back surface and pasted so as to overlap with the scratch concealment layer formed. An adhesive layer was provided in the lower layer to obtain an image information recording medium of the present invention.

  In the image information recording media of Examples 1 and 2 described above, when the upper substrate is turned over and the scratch concealment layer is scraped with a coin or the like, the first image and the second image overlap and the individual image information is combined. Also, if you do not want to know this individual image information other than those concerned, you can not see it if you remove the base material above, so the individual image information that you do not want to be known by other people It is possible to recognize individual image information easily without being known to other parties by superimposing two pieces of encrypted information (image) when necessary by the parties involved. Can provide an information recording medium that is difficult to perform.
