Description

  The present invention relates to a novel ID card.

  Currently, there are many types of identification cards (hereinafter referred to as ID cards) such as driver's licenses for cars, passports, alien registration cards, identification cards, membership cards with photos, business cards with photos, etc. It has become widespread.

  Conventionally, an ID card image has, for example, a structure in which a face photograph or a character image is formed on the surface of a support by silver salt photography, and a protective layer is further provided on the surface. A gradation image such as a face photograph by the silver salt photography method can obtain an overwhelmingly superior image quality as compared with the case of using other recording means. However, in contrast to this, the silver salt photography method has a problem that it lacks sharpness or density when it tries to obtain binary images such as characters or marks at the same time. This is derived from the gradation of the silver halide photograph, and the binary image is deteriorated because the gradation image is optimized.

  Under such circumstances, there is a method of embedding a face photograph part in a card or sandwiching it in a laminate sheet, and recording other characters by a recording method suitable for a binary image, for example, a method using printing or various printers. Has been taken. However, in the case of this method, it takes time to embed or insert the card in the card, resulting in an ID card that lacks monolithic finish.

  In response to the above problems, a method of printing an image by a sublimation transfer printing method on a plastic card, and providing a card by oversheeting after printing (see, for example, Patent Document 1), a facial photograph or character information by an inkjet recording method. Printed and printed cards have been proposed (see, for example, Patent Document 2). In addition, an ID card is proposed in which a heat-diffusible dye image-receiving layer is provided, and a dye image is received on the image-receiving layer to form a transfer image, and then an ultraviolet curing protective layer is provided to provide a high-quality face image and the like. (For example, refer to Patent Document 3). With these proposed methods, it is possible to obtain prints that are close to silver salt. However, since all the prints and prints on the card are performed using the same print method or print method, there are problems in terms of card productivity and cost. In addition, the durability of the formed images and characters is not sufficient.

  Due to the above-mentioned disadvantages of card productivity and cost, a method has been proposed in which a part of the card is first printed by a highly productive printing method, and the face image portion for personal authentication is printed by a method such as sublimation printing. ing. For example, on a support, it has an image receiving layer which is formed by printing format information and accepts a heat diffusible dye and can form an image, and further transparent on at least a standard format printed area on the image receiving layer. In the region where the resin layer is provided and the image is formed by receiving the heat-diffusing dye, the surface of the image receiving layer is used, and the surface of the image receiving layer of the ID card substrate is exposed. An ID card manufacturing method in which image recording is performed by thermal transfer of a thermal diffusible dye in a region where heat transfer is performed, and character information is recorded by melt-type thermal transfer in a predetermined region provided with a transparent resin layer. After recording by thermal transfer on the substrate for heat transfer, the thermal adhesive resin layer is thermally transferred to protect the character information and the heat diffusible dye image. Irradiate ID cards which can be cured is proposed (for example, see Patent Document 4.). In the ID card proposed above, character images are melted and thermally transferred, and a gradation image such as a face image is recorded by sublimation heat transfer, so that a sense of unity can be achieved without taking time and effort such as embedding or sandwiching in a card. Although a high ID card can be realized, in the printing method of format information, consideration for print quality and productivity is still insufficient.

  In recent years, the use of plastic cards as information recording media represented by, for example, credit cards and cash cards has been rapidly expanding. These plastic cards are often subjected to various printing such as letters, numbers, symbols, patterns, designs, etc. on the surface by an offset printing method. This offset printing method has an advantage that, for example, the productivity is superior to conventional silk printing and the like, and in the planographic offset printing, high-definition printing is possible. Since lithographic offset printing is flat, the plate making is relatively easy and the plate can be made with high precision, and is therefore known as mass printing.

  In recent years, lithographic offset printing has come to use CTP plate making (computer-to-plate), which does not use a film for plate preparation, but makes plate preparation directly from computer data. The CTP plate makes it possible to reduce intermediate materials such as plate-making films, reduce the number of placement personnel, and quickly produce plates.

  Further, for lithographic offset printing, printing with water using fountain solution and printing without water developed by Toray Industries, Inc. are known. As a material for a card substrate suitable for this lithographic offset printing, vinyl chloride resin is the most widely used because it is cheaper and more easily accepts printing ink and has excellent printability. From the environmental problem of resin, examination of other base materials is made (for example, refer to patent documents 4 and 5).

  For ID cards, environmental printing, high productivity, low cost, high quality printing, and printing of good face images, etc., format information can be printed with high quality, high productivity, and low cost by lithographic offset printing. There is a demand for an ID card that is printed and embedded without embedding a face image close to a silver halide photograph in a face image that can be identified by printing.

  From that request, a thermal diffusion dye transfer capable of printing an image equivalent to a silver salt photograph on a polyester or polycarbonate sheet, an image receiving layer capable of receiving an ink jet printing, and a lithographic offset method in a part of the image receiving layer. An ID card is proposed in which high-quality printing is performed, printing is performed by printing or fusion heat transfer, and a protective layer is provided thereon (see, for example, Patent Document 6), but the durability of the lithographic offset printing surface is poor. The printed surface before the protective layer is provided may be peeled off even if it is worn slightly, the printability of the melt thermal transfer is poor, the protective layer is poorly adhesive, and the protective layer becomes obsolete during or after card production. There were many problems such as peeling off.

  Lithographic offset printing inks generally use process inks consisting of yellow, red, indigo and black, and are printed with multi-color printing using process inks. However, the above problems are worse with multi-color printing, and also when black ink is used. It turned out to be a problem.

In lithographic offset printing, in addition to using process inks, inks obtained by blending inks, so-called special color inks, inks located on coordinates outside the color reproduction area of process inks, such as pearl inks, metallics, etc. Although so-called special inks such as inks and fluorescent inks are sometimes used, it has been found that when special color inks or special inks are used, the above problem is increased even with a single color, and stains on the printed surface are likely to occur.

  Examples of the special ink located on the coordinates outside the color reproduction region in the present invention include pearl ink, metallic ink, and fluorescent ink.

  In the present invention, a method of forming image information using a color change ink called a pearl ink whose color changes depending on an angle viewed on an image of a card is also mentioned. The pearl ink contains thin metal particles or the like as a pigment, and has a property of multiply reflecting light by the metal particles. The reflected light has a light wavelength, that is, a color, which is determined by the thickness and particle size of the metal particles, and causes the color change when the lights interfere with each other. In the present invention, the pearl ink having the property of changing the color due to the interference of the reflected light is used for the image information formed on the ID card, so that when the created card is copied, the area where the image is formed with the pearl ink. This makes it possible to prevent forgery of the card by copying. Further, it is possible to easily discriminate between regular cards and copies.

  Pearl ink contains pearl pigment, and pearl pigment used to be pearl powder or fine powder in the inner part of shells in the past, but now the outer side of fine flakes (flakes) is oxidized with metal. A material or a mixture of metal oxides is mainly used.

The fine flakes include, for example, mica, talc, kaolin, bismuth oxychloride, glass flakes, SiO ₂ flakes, or synthetic ceramic flakes, and the metal oxide covering the outside of these fine flakes. _{examples, TiO 2, Fe 2 O 3} , SnO 2, CrO 3, there is ZnO.

Can do.

  The metallic ink used in the ID card of the present invention is preferably a printing method that can form a thick image film, obtain a metallic luster with a large density of metal powder, and a relatively coarse particle size. It is desirable to adopt an image forming method that satisfies the durability that the metallic ink image does not peel off from the image forming layer even when an external force such as twisting is applied, and the weather resistance and friction resistance that develops a metallic luster over a long period of time. As a technique for forming such a metallic ink image having excellent durability, for example, a printing technique using a metallic ink disclosed in JP-A-8-290646 can be cited.

  Metallic ink generally refers to ink containing metal powders such as metal flakes that exhibit a metallic luster by reflecting light, or powders that change the refractive index. It is made by mixing. For example, for gold ink, brass powder or yellow colored aluminum powder is used. Moreover, what changed the color tone, such as a red mouth and a blue mouth, is obtained by adjusting the zinc content in brass or adjusting the coloring of the aluminum foil. Aluminum powder is used for the silver ink.

  The metallic ink used in the present invention is used by appropriately adjusting the particle size and density of the metal powder according to the ID card production method.

  In this way, the ID card of the present invention is a metal that is unique to the metallic ink of the regular card even if the ID card is copied by color copy by creating the card using metallic ink for printing the format information. The material texture cannot be reproduced. Then, it is possible to visually discriminate between a genuine product and a fake product with a considerable degree of accuracy by simply giving a metallic luster to a specific pattern in the image information created on the ID card.

  In addition, as the material of the fluorescent ink, for example, a material containing an inorganic fluorescent pigment, an organic fluorescent pigment, a vehicle or the like having a particle size of 0.7 to 50 μm at a mass ratio of 15 to 45% is used.

As an inorganic fluorescent pigment, it is excellent in durability and weather resistance. For example, crystals such as oxides such as Ca, Ba, Mg, Zn, and Cd, sulfides, silicates, phosphates, and tungstates are mainly used. As a component, a pigment obtained by adding a metal element such as Mn, Zn, Ag, Cu, Sb, Pb, or a rare earth element such as a lanthanoid as an activator, for example, JP-A-50-6410, said 61-65226 Patent, the 64-22987 Patent, the 64-60671 Patent, can be appropriately used inorganic phosphors described in JP-a 1-168911 Patent. as the crystal matrix, Y ₂ Metal oxides typified by O ₂ S, Zn ₂ SiO ₄ , Ca ₅ (PO ₄ ) ₃ Cl, and sulfides typified by ZnS, SrS, CaS, etc., Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, H , Er, Tm, ions or Ag rare earth metal such as Yb, Al, Mn, is a combination of metal ions such as Sb as an activator or co-activator preferred.

  The crystal matrix and the activator or coactivator are not particularly limited in the composition of the elements, and can be used even if they are partially replaced with elements of the same family, as long as they absorb visible light from the ultraviolet to the blue region. Any combination can be used, but it is preferable to use an inorganic oxide phosphor or an inorganic halide phosphor.

  As the organic fluorescent pigment, since it can be made small in particle size, it is easily converted into an ink. And compounds having a benzene ring such as dyes and anthracene.

  As the vehicle, for example, a vehicle having no absorption region in the visible light region having a wavelength of 400 to 700 nm is used. From the viewpoint of high thermoplasticity (low thermosetting property), for example, natural resin (for example, , Protein, rubber, cellulose, shellac, copal, starch, rosin, etc.), vinyl resin, acrylic resin, styrene resin, polyolefin resin, novolac phenol resin, resol phenol resin, urea resin, melamine resin, polyurethane Resins, epoxies, and unsaturated polyesters are used. Preferably, a photopolymerization curable type or electron beam curable type acrylic resin which is not easily contaminated because a solvent is unnecessary is used.

(Lithographic offset printing using at least one carbonless black ink)
The invention according to claim 4 or claim 8 is characterized in that the format information is printed by lithographic offset printing using at least one kind of carbonless black ink.

  The carbonless black ink as used in the present invention is a process ink, such as yellow, magenta, and cyan inks, for example, 1: 1: 1 without using black pigment carbon black. It is an ink prepared by mixing a resin, a matting agent or the like as an additive as required.

  Next, other elements related to the ID cart of the present invention will be described.

  In the present invention, after the format information is printed, it is preferable to print at least the transparent resin layer 2 provided on the format information printing region by a printing method other than the planographic offset printing.

  In the ID card of the present invention, it is preferable that the lithographic offset printing used for printing the format information is lithographic water offset printing which is a method of applying dampening water with a dampening water roller or the like. If necessary, lithographic waterless offset printing without using dampening water can also be used.

  In the ID card of the present invention, it is preferable that the plate used for lithographic offset printing is a fair dot screen.

  In general, as a gradation reproduction method for color printing, AM screen (Amplitude Modulation) that expresses gradation by the size of halftone dots (for example, square, chain, round shape) is known. In the AM screen, the tone is reproduced in a regular arrangement with halftone dots of different sizes. However, since the halftone dots are arranged at a constant pitch on the AM screen, Rosetta moire, interference moire, tone jump Such a problem occurs. On the other hand, there is an FM screen (Frequency Modulation) that arranges dots of the same shape randomly and changes the dot density per fixed area to express gradation, and this method can achieve high-definition print quality. However, since the density of unit dots is extremely high in the middle tone portion, it has a drawback that it is difficult to print compared to the AM screen.

  In recent years, a method that uses the dot structure and arrangement of each of the above-described methods and selectively uses the dot density and shape according to the density of the image, that is, a fair dot screen has been developed.

  In the fair dot screen, in a highlight area with a density of 1 to 10% and a shadow area with a density of 90 to 99%, a halftone dot having a certain size is used to express gradation by changing the density as in the FM screen. . On the other hand, in the halftone region having a density of 10 to 90%, the dot size (indefinite shape) is changed similarly to the AM screen, and the dot arrangement is randomly arranged as in the FM screen. The occurrence of interference due to differences is reduced.

  In the present invention, the use of a plate composed of a fair dot screen is preferable from the viewpoint of controlling the graininess and obtaining a high-quality image excellent in tone reproducibility.

  In the ID card of the present invention, the entire back surface of the card is preferably subjected to resin lamination or transparent resin layer printing. Examples of these coating methods include those described in Convertec (1990.1-19933.3), and examples of the resin laminating method include wet lamination, dry lamination, and non-solvent. Lamination, extrusion lamination, etc. can be mentioned, and as a transparent resin layer printing method, for example, gravure printing, offset printing, flexographic printing and the like can be used.

  Examples of the resin used for the resin laminating process or transparent resin layer printing include acrylic resins such as acrylic acid esters and methacrylic acid esters, polyester resins such as polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, polycarbonate, and polyarylate. Polyvinyl chloride, polyvinylidene chloride, polyvinylidene fluoride, polyolefin resins such as polyethylene, polypropylene and polystyrene, polyamide resins such as nylon and aromatic polyamide, polyetheretherketone, polysulfone, polyethersulfone, polyimide, polyetherimide , Polyparabanic acid, phenoxy resin, epoxy resin, urethane resin, melamine resin, alkyd resin, phenol resin, fluorine resin, silicone resin The resin that forms this resin laminate layer is preferably a resin that has a small neck-in and good drawdown properties, such as high-density polyethylene, medium-density polyethylene, low-density polyethylene, and polypropylene.
