Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a printed matter in which counterfeiting of tickets, commuter passes, admission tickets, etc., and in particular, counterfeiting by copying.
[0002]
[Prior art]
Conventionally, on the surface on which the sections such as tickets, commuter passes and admission tickets and the date and time are printed, fine patterns such as letters and marks are printed as endless patterns, which have been regarded as a means to prevent counterfeiting. Recently, the accuracy of color copiers has improved, and almost the same products have been copied with some background patterns and fine marks. When visual judgment is required, It has become very difficult to distinguish.
[0003]
Therefore, in Japanese Patent Laid-Open No. 59-202899, a printing film or a transfer foil provided with an outer surface that expresses an iris interference fringe is adhered or transferred to the surface of an autograph, photograph, or company badge. A method for preventing counterfeiting is described. However, in this case, it is a method of preparing and pasting a printing film or transfer foil with an outer surface that expresses iris-colored interference fringes that can be distinguished at a glance. In the case of a large amount of paper that is printed and issued immediately before, it cannot be pasted each time, and when it is a transfer foil, a transfer process other than printing, and an apparatus therefor Is required, and it takes time to issue the ticket, and the cost is very high, which is not realistic. In addition, the iris color that can distinguish gloss at a glance makes it difficult to see the underlying layer and prevents obvious counterfeiting, so it does not give a good impression to most regular users. It was.
[0004]
Also, tickets and admission tickets are supplied with rolls of raw material rolled up to a certain width, and are used while being cut at regular intervals. It was impossible to print some marks in advance, and it was more difficult to prevent forgery.
[0005]
[Problems to be solved by the invention]
Therefore, the present invention has been made to solve the above-described problems, and has a heat-sensitive or pressure-sensitive color developing layer on the substrate, and more reliably prevents counterfeiting of printed matter printed immediately before. It is an object of the present invention to provide an anti-counterfeit printed matter that can be made less prominent and unnecessary in terms of cost.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the solution means of the present invention comprises a heat-sensitive or pressure-sensitive color-developing layer laminated on one side of a base material layer, and a tint block, a fine mark or a monochromatic solid printing is printed on the heat-sensitive or pressure-sensitive color developing layer. In the anti-counterfeit printed matter in which a light coherent reflective layer in which a pearl pigment is mixed is formed on the printed layer, the light coherent reflective layer is partially formed and the light coherent reflective layer is formed. An anti-counterfeit printed matter characterized in that a colored layer of the heat-sensitive or pressure-sensitive coloring layer is recognized from a portion that has not been printed . In this way, the light-interfering reflective layer mixed with the pearl pigment that is not so noticeable on the printed matter will appear as a very conspicuous color tone on the layer colored by heat or pressure. Thus, forgery prevention is achieved.
[0007]
In addition, as described above, by providing a printing layer on the heat-sensitive or pressure-sensitive color developing layer provided on one side of the base material layer, that is, a background pattern, fine marks, etc., or solid color printing, color is generated by heat or pressure. It is possible to make the light coherent reflective layer less conspicuous in other places.
[0008]
In addition, the anti-counterfeit printed matter, which is a layer that reflects light of a certain wavelength and transmits light of other wavelengths, can have a hue that can be easily identified by humans.
[0009]
In addition, by making the heat-sensitive or pressure-sensitive color developing layer a forgery-preventing printed matter that develops black color under certain conditions, it is possible to absorb the wavelength transmitted through the light-interfering reflective layer, and to reflect only the original reflected wavelength. In addition, since a hue different from that which has been seen until then appears, it can be easily discriminated visually, and the effect of preventing forgery is improved.
[0010]
Next, a heat-sensitive or pressure-sensitive coloring layer is provided on one side of the base material layer, or the heat-sensitive or pressure-sensitive coloring layer is laminated on one side of the base material layer, and printing is performed on the heat-sensitive or pressure-sensitive coloring layer. By using a forgery-preventing printed matter having a light reflectance of 50% or more on the surface in the state where the layer is provided, the amount of reflected light other than the light-interfering reflective layer increases, so that the color other than color due to heat or pressure The light-interfering reflective layer at the location can be made less conspicuous, and the difference from the hue that develops color due to the heat or pressure can be increased, and the hue that develops color is particularly dark, such as black. In the case of a hue that hardly reflects, the difference becomes particularly large, and discrimination becomes easy.
[0011]
Next, by making the anti-counterfeit printed matter in which the hue of the reflected light of the light interference reflective layer and the hue of the printing layer are similar colors, the light interference reflection at a place other than the color due to heat sensitivity or pressure sensitivity Since the layer can be made indistinguishable from the printed layer, it is possible to make it easier to discriminate the iris color at the location where the color is developed by heat or pressure.
[0012]
Similarly, by using a forgery-proof printed matter in which the hue of the transmitted light of the light-interfering reflective layer and the hue of the printed layer are similar colors, only light of a certain wavelength is reflected by being originally transmitted, By coherently reflecting the transmitted light where the monochromatic light is supposed to be seen, it becomes almost the same reflected light as the incident light. Since the layer can be made indistinguishable from the printed layer, it is possible to make it easier to discriminate the iris color at the location where the color is developed by heat or pressure.
[0013]
Next, the anti-counterfeit printed matter in which a transparent protective layer is laminated on the light coherent reflective layer can increase the surface strength and prevent the light coherent reflective layer from peeling off due to friction or rubbing. Therefore, it is possible to surely prevent forgery.
[0014]
Next, by using a forgery-preventing printed material having a magnetic layer formed on the other surface of the base material layer, discrimination other than visual recognition is possible, and forgery prevention can be achieved more reliably.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. 1-3 Ri FIG der showing an embodiment of the present invention, FIG. 4 is a diagram for explaining the reflection of light interference reflecting layer, FIG. 5 is a diagram showing another embodiment 10 is an anti-counterfeit printed matter , 11 is a base material layer , 12 is a heat-sensitive or pressure-sensitive color developing layer , 15 is a light interference reflective layer , 13 is an anchor layer, 14 is a surface printed layer, 16 and 19 are transparent protective layers, 17 Is a magnetic layer, and 18 is a back printed layer.
[0016]
First, the anti-counterfeit printed matter 1 in a form suitable for the ticket or admission ticket shown in FIGS. The anti-counterfeit printed matter 1 shown in FIG. 1 is a printed layer that is a background pattern (not shown) formed by a company mark or the like after the thermosensitive coloring layer 3 is laminated on the base material layer 2 made of paper having a white surface. Then, the light coherent reflection layer 5 having a constant width is provided by printing at both ends.
[0017]
A laminated body as shown in FIG. 1 is usually wound up in a roll shape and set in a ticket machine or the like (not shown). After that, when purchasing a ticket, an admission ticket, etc., the date, boarding section, serial number, etc. are thermally printed by a ticket vending machine, etc., and the ticket, the admission ticket, etc. are issued in a black colored state. FIGS. 2 and 3 show the state after the issuance. However, as long as the color can be developed, the present invention is not limited to a ticket vending machine, and can also be applied at the time of ticket checking and other cases. In FIG. 2, a portion thermally printed in black by a ticket vending machine or the like is shown as a colored layer 3b, and the other portion is shown as an uncolored layer 3a. At this time, the optical coherent reflective layer 5 is not formed in the central portion of the forgery-preventing printed matter 1, and the optical coherent reflective layer 5 is formed only at both ends. In this case, the colored layer 3b where the light coherent reflective layer 5 is not formed is recognized as normal black, and the colored layer 3b where the light coherent reflective layer 5 is formed is the light coherent reflective layer. 5 and is recognized as a hue having a green pearl luster, for example.
[0018]
This principle will be briefly described with reference to FIG. The pearl pigment 5b contained in the light-interfering reflective layer 5 is a pigment configured to express pearl luster by coating the core material of the granular material with a special substance, and particularly the surface of the mica powder. Those coated with a titanium compound are suitable. In this embodiment, a mica powder coated with titanium dioxide (see, for example, Japanese Patent Laid-Open No. 60-60163) is used. As shown in FIG. 4, the pearl pigment 5b is a vehicle 5a. It is uniformly dispersed and formed in a parallel oriented state. Here, the pearl pigment 5b interferes with any of the wavelengths of the visible light L incident according to the film thickness of the titanium dioxide, and the reflected light L ′ exhibits a specific hue. The pearl pigment 5b used may have a uniform titanium dioxide film thickness so as to obtain reflected light of the same color, or a mixture of different film thicknesses to obtain reflected light of various hues. You may be made to do.
[0019]
Here, the mica titanium-based pearl pigment exhibits various interference colors depending on the thickness of the titanium dioxide coating layer on the surface of the mica particles. That is, when the amount of titanium dioxide is 10 to 26% by weight of the product, the interference color is usually silver, but when it is 26 to 40% by weight, it is gold, and when it is 40 to 50% by weight, the titanium dioxide coating layer increases. , Red, blue, and green. Further, when the content is 50 to 60% by weight, a high-order interference color can be obtained. At that time, the hue of the transmitted light changes in order of purple, yellow-green, orange and red due to the complementary color relationship.
[0020]
In addition, in the case of the optical coherent reflective layer 5, when the underlying layer is visible, the reflected light is affected by the hue of the underlying layer. That is, if the base layer is close to white and has a high light reflectance, even if reflected light having a specific wavelength is obtained by the optical coherent reflective layer 5, the reflected light reflected by the base layer Therefore, the reflected light of a specific wavelength by the light coherent reflection layer 5 is almost invisible. Therefore, in order to make the reflected light from the light coherent reflective layer 5 as easy to see as possible, the light coherent reflective layer 5 should be made black or a dark color close to black as much as possible so as not to be reflected by the underlayer. It is important to make the reflected light of a specific wavelength due to. In particular, when the mica titanium-based pearl pigment described above has reflected light other than silver, and there is transmitted light of a color located in the complementary color relationship, it is clearer by making the base layer black. Reflective light with a proper hue can be obtained, and the effect of preventing forgery is very high. Examples of pearl pigments suitable for such applications include Iriodin 200 series manufactured by Merck Japan. More specifically, 20 to 25 parts of pearl pigment having an average particle diameter of 5 to 20 μm, 10 to 12 parts of nitrocellulose, and 75 to 80 parts of medium containing additives such as a plasticizer and polyethylene wax are included. The present embodiment can be produced by gravure printing with ink mixed in the ink.
[0021]
Further, the print layer 4 may be a fine endless pattern or a monochromatic solid print. However, as for the hue, the light-interfering reflective layer 5 may be less noticeable in the light color as described above, and those having a light reflectance of 50% or more are suitable. In other words, by doing this, glossiness does not appear in unnecessary portions and it is not necessary to make a hard-to-see printed matter, and the difference from the portion for determining forgery prevention is increased, making discrimination easier. It will be something that can be done.
[0022]
Furthermore, although the hue of the printing layer 4 was not touched in the above-described embodiment, the hue of the printing layer 4 and the reflected light or transmitted light of the coherent reflective layer 5 are set to the same color, so that heat sensitivity or pressure sensitivity is achieved. Gloss due to the light-interfering reflective layer 5 becomes almost invisible at places other than those that are colored due to, and the difference from the glossy feeling of the colored areas due to heat or pressure sensitivity becomes clear, and the forgery prevention effect becomes higher Is. Further, a protective layer made of a transparent resin may be provided on the surface of the anti-counterfeit printed matter 1 to protect the surface of the light interference reflective layer 5, and a magnetic layer is formed on the back side for machine-readable applications. As a thing, it is good also as what improved the forgery prevention effect more.
[0023]
Further, as the heat-sensitive color developing layer, a layer composed of a conventionally known color former that develops color by heat and a binder having a high melting point can be used. For example, as a color former that develops color by heat,
(1) Long-chain fatty acid iron such as ferric stearate and ferric behenate and gallic acid, gallic acid methyl ester, gallic acid lauryl ester, protocatechuic acid, protocatechuic acid ethyl ester, 3,4-dihydroxybenzophenone Combination with phenols such as
(2) A combination of a long chain fatty acid metal such as cupric behenate and a metal chelator such as diphenylcarbazide.
(3) Phenols and certain photochromic benzoindolinospiropyran compounds
(4) It may be selected from a combination of leuco dye such as crystal violet lactone and phenol. Similarly, as the binder, 180 of cellulose acetate, methyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, polyvinyl alcohol, etc. It is preferable that the material is selected from those having a high melting point of at least ° C.
[0024]
Next, another embodiment will be described with reference to FIG. Figure 5 is a diagram showing a laminated structure of anti-counterfeit printed matter 10 when it is utilized on a regular ticket, thermal or pressure sensitive coloring layer 12 on the surface of the base layer 11 made of a transparent biaxially stretched polyester film, an anchor layer 13, a surface printing layer 14 made of white solid printing and pattern printing such as a tint block pattern is printed on the anchor layer 13, and the light interference reflective layer 15 and chemical resistance are further formed on the surface printing layer 14 surface. A transparent protective layer 16 having thermal head characteristics for thermal printing is sequentially laminated, and a magnetic layer 17, a back surface printed layer 18 made of white characters and the like, and a transparent protective layer 19 are sequentially laminated on the back surface.
[0025]
Also in this embodiment, it is exactly the same as the above embodiment, and the time limit, the use section, the amount of money, the name, etc. are thermally printed at the time of use, and the light-interfering reflective layer 15 is formed on the portion colored by the thermal printing. By adopting such a configuration, the same effects as those of the above embodiment can be obtained.
[0026]
Although the present invention has been described with reference to the two examples, the present invention is not limited to these examples. For example, only the heat-sensitive color developing layer was described for the color developing layer, but it was naturally encapsulated on the same surface. A pressure-sensitive color-developing layer formed by providing a color former and a developer may be used, and these may be used properly depending on the application. In addition, we have explained about tickets, commuter passes, admission tickets, etc., but of course there are things that can be used by visual judgment, such as gold vouchers, securities, etc. It is. In addition, as a shape for coloring the heat-sensitive or pressure-sensitive color-developing layer and discriminating with the light-interfering reflective layer, a shape having a certain area is better than characters with thin lines, □ marks painted black, ☆ marks and white letters are suitable.
[0027]
【The invention's effect】
As described above, the present invention provides a forgery prevention structure in which a heat-sensitive or pressure-sensitive color-developing layer is laminated on one surface of a base material layer, and a light-interfering reflective layer mixed with a pearl pigment is formed on the heat-sensitive or pressure-sensitive color-developing layer. Since it is a printed matter, the light-interfering reflective layer mixed with the pearl pigment that is formed so that it is not so noticeable on the printed matter clearly reflects on the hue developed by heat or pressure sensitivity and is visible, preventing counterfeiting Will come to be planned.
[0028]
In addition, the light-interfering reflective layer reflects a certain wavelength and transmits other wavelengths, or the heat-sensitive or pressure-sensitive color-developing layer is colored black under certain conditions, or on one side of the base material layer. The surface has a light reflectance of 50% or more in a state in which a heat-sensitive or pressure-sensitive color-developing layer is laminated, or a state in which a heat-sensitive or pressure-sensitive color-developing layer and a printing layer are laminated on one side of the base material layer, By making the hue of the reflected or transmitted light of the reflective layer and the hue of the printing layer similar, the hue of the non-colored part and the colored part can be clarified and the anti-counterfeiting effect can be further improved. It will be.
[0029]
Furthermore, by laminating a transparent protective layer on the light-interfering reflective layer, it becomes possible to provide friction resistance without causing attenuation of the reflected wavelength, and reliable counterfeit prevention can be achieved. In addition, by forming a magnetic layer on the other surface of the base material layer, discrimination other than visual observation is possible, and a double check is performed, so that forgery can be prevented more reliably.
