Prior art

In recent years there have been made various proposals in order to prevent imitation, copying or the like with respect to the various seals and printed documents, personified in securities and cards. For example, each of patent documents 1 to 4 offers printing using a printing ink containing a colorless pigment, which cannot be seen in normal light and is excited by ultraviolet rays to emit visible light. Patent document 5 proposes a structure which is excited by infrared radiation for emitting infrared radiation. Each of patent documents 6 and 7 offers printing and the main part of the display of the print, each of which uses a fluorescent agent, which is not in the t visible light from infrared rays. In each of these sentences information is formed by the sequential layering of dye layers for respective colors on the writing paper or recording medium. When trying to burn a large amount of information in this way, the number of layered layers of dye increases, then the printing or recording medium becomes thicker. In addition, in the recording medium or printing, in which information composed of multi-layered material layers of dye, the respective dyes, components of information are independent from each other. Therefore, the dyes in the layers of dyes can be identified to those who intends to commit forgery or modification.

The imprint of the present invention is an imprint formed by overlapping multiple layers of printing ink, characterized in that the first layer of ink is formed on the recording material through a first ink having the property of fluorescence radiation; a second layer of ink is formed on the first layer of printing ink through the second ink; the first layer of printing ink exposed point on the second layer of printing ink; and a seal formed of at least one of the first layer of printing ink and the second layer of printing ink. With this feature, the optical density of the second layer of printing ink is comparable with the optical density of the print, composed of only the second layer of printing ink, and is sufficient for the impression, and the first layer of printing ink cannot be detected. In addition, the radiation may be in the form of point-emitting section when the optical impression increases with magnification of from 5 to 10, so that the radiation may be in the form of the radiating section in the Orme line or plane (subsequent examples without explanation satisfy this condition and provide this result).

Figure 1 shows the imprint of the present invention when considering on the printed surface. In the figure section 1 corresponds to the part of the layer of printing ink formed by the first ink. Section 2 corresponds to the portion of the layer of printing ink formed by the second ink. Part 1 of the first layer of printing ink exhibited by the point pattern on the second layer 2 ink. Spot exposure determines the relative location between the layer of fluorescent ink or fluorescent particle in it and a layer of printing ink, which must be layered, or colored dye in it. Even if the layer of printing ink layered, fluorescent radiation may be in the form of point-emitting section for evaluation according to the increase by means of lenses or the like. At the same time, the fluorescent radiation can be observed in the form of the radiating section in the form of a line or plane.

Section 2 corresponds to the area of the second layer of printing ink. In addition, the dotted lines indicate the thickness of the second layer of printing ink (that is the woman printed cover). Since the thickness of the second layer of printing ink is less than the thickness of the first layer of printing ink, the second layer of printing ink is recorded in each interval between the bumps of the first layer of printing ink. Therefore, the optical density of the second layer of printing ink (for example, 1,40) is approximately equal to that of the second layer of printing ink (for example, 1,43).

In the above description, when the first layer of printing ink is formed by printing ink, which uses the radiation wavelength infrared range as the excitation energy to emit fluorescence, the imprint may find use in increasing the number of protective applications. In addition, when the first layer of printing ink formed by printing ink, which uses the radiation wavelength infrared range as the excitation energy to emit fluorescence in the visible region of wavelength, the imprint can be easily recognized. In addition, when the wavelength region of the emission spectrum of the first layer of printing ink is a region of wavelengths of the absorption spectrum of the second layer of printing ink, it becomes possible to use the characteristics of the imprint of the present invention. That is the impression which the first almost not recognized by the eyes under normal circumstances due to the large area printing of the second layer of printing ink, can be observed with a microscope or by irradiation of radiation of wavelength infrared range, when the first layer of printing ink is formed above ink. When the colorant of the first ink forming the first layer of printing ink is a pigment, the first ink can be easily exposed by the point pattern in the second layer of printing ink. The colorant of the first ink, in particular, preferred is an inorganic pigment.

The colorant of the first ink, in particular, also preferably is a dye containing multiple lanthanides. When the dye of the second printing ink forming the second layer of printing ink is afluorescent dye, a fluorescent property of the first layer of printing ink can easily be observed. The dye of the second layer of printing ink is preferably a pigment, in particular preferably an inorganic pigment. In addition, when the dye of the second layer of printing ink is carbon black, the first layer of printing ink can be easily recognized, because the second layer of printing ink absorbs most of the radiation in the visible region of the spectrum.

The recording method of the present invention is a recording method for forming print overlay multiple layers of printing ink, and the method includes forming the first layer of printing ink from the first ink having the property of fluorescence radiation, on the recording material; and forming a second layer of printing ink from the second ink on the first layer of printing ink, in which the average particle size of the dispersing element, dispersed in the first printing ink is larger than the average particle size of the dispersing element, dispersed in the second printing ink. The difference in the average particle size is preferably such that the fluorescent particles have an average particle size of 0.5 μm or more to approximately 3 μm (preferably 1 μm or more to 2 μm or less, and more preferably particles having an average particle size in this range, appropriate what was estavao 40% or more relative to the first printing ink), while the colored dye has an average particle size of about 10-9m (1 nm). More precisely, the fluorescent particles are preferably particles of inorganic pigment, and a color dye preferably is an organic dye or organic pigment.

The recording method of the present invention is a recording method for forming a seal with the application of multiple layers of printing ink, and the method includes forming the first layer of printing ink from the first ink having the property of fluorescence radiation, on the recording material; and forming a second layer of printing ink from the second ink on the first layer of printing ink, the thickness of the first layer of ink formed on the recording material (the thickness of the printed surface)is greater than the thickness of the second layer of printing ink. Printing ink used for formation of the imprint contains a colorant such as a pigment, and a dispersant to maintain the state of dispersion of the colorant in the liquid or film-forming material or binder for fixing the dye on the printing paper (hereinafter, the term "printed paper" also refers to the recording medium after printing Kras is and used for recording information. Examples of recording media include conventional commercially available recording media, such as cellulose, fibers, plastics, gummed paper and corrugated cardboard; and obtained through exposure to the aforementioned recording media sequence applying a layer for coloring.

The imprint of the present invention is formed according to any of various printing methods. For example, as conventionally known liquid media for ink when the print is formed according to the inkjet method, mainly, is water or a mixture of water and a water-soluble organic solvent. Examples of water-soluble liquids include water-soluble alcohols, and water-soluble polyhydric alcohols such as ethylene glycol, propylene glycol, diethylene glycol, triethylene glycol and glycerin. In addition, to ensure the ability of the dispersion of the pigment in the aquatic environment, liquid substance includes any of the pigment dispersant, such as various surfactants and water-soluble resin. Illustrative examples of water-soluble resins include acrylic resins having a water-soluble group such as carboxyl group or Quaternary ammonium group.

Examples of the resin include acrylic resins, copolymer vinyl chloride-vinyl acetate resin, a copolymer of ethylene-vinyl acetate resin, polyester resin, polyamide resin, based on the cellulose resin, polyurethane resin and globalproperty resin. Ink, on demand, additionally contains a substance that forms cross-links, or the like. Examples of the organic solvent, when the imprint formed by oil-based printing ink for gravure printing, include methyl ethyl ketone, toluene, xylene, cyclohexanone, cyclohexane and alkyl substituted cyclohexane. Examples of film-forming material (binder) for ink include the above water-insoluble resin. Oily printing ink, in a similar manner, upon request, contains a substance that forms cross-links.

In addition, when the seal of the present invention is formed by offset printing, letterpress or template printing liquid is emesto for ink, used for each print contains the solvent is hydrocarbon-based and film-forming material having the polymerized by oxidation of the double bond, such as paloaltogreen oil, dehydrated butter, modified rosin phenol resin, kumaran-indene resin or alkyd resin. Any of the above liquids (paint binder) for ink is widely known, and any of the other well known liquid media can be used for ink for formation of a seal according to the present invention. Despite the fact that liquids for ink used in the illustrative printing methods, have been described above as an example, liquids for ink used in other printing methods are also applicable.

The main feature of the present invention is that the fluorescent dye is used for the first printing ink as dye ink for any of the above well-known printing methods. The term "fluorescent dye" means a dye that uses light having a specific wavelength as the excitation energy to emit light radiation in a different wavelength, which does not include the length of any for excitation. Of these dyes is preferred pigment having the property of high resistance. Paint can be used in combination, depending on the applications and purposes.

Fluorescent dye to be used in the present invention, which has the property of fluorescent radiation and is used for printing ink, produces a spectrum, when it is excited by ultraviolet light radiation, and then returns to a lower energy level. In addition, the peak of the spectrum is in the region of wavelengths of blue, green, red or the like. The dye is obtained by adding small amounts of metal (such as copper, silver, manganese, bismuth, or lead), as an activator to enhance the radiation in high-purity fluorescent material such as zinc sulfide or sulfide of alkaline earth metal; and sintering the mixture at a high temperature. Hue, brightness and the degree of cotopognosy ultraviolet fluorescent pigment can be adjusted in accordance with the combination of the main crystal and activator.

Some examples of fluorescent dyes include Ca2B5O9Cl:Eu2+, CaWO4, ZnO:Zn, Zn2SiO4:Mn, Y2O2S:Eu, ZnS:Ag, YVO4:Eu, Y2O3:Eu, Gd2 O2S:Tb, La2O2S:Tb, Y3Al5About12:Ce, Sr5(PO4)3Cl:Eu, 3(Ba, Mg)O·8Al2O3:Eu, Zn2GeO4:Mn, Y(P, V)O4:Eu, 0,5MgF2·3,5MgO·GeO2:Mn, ZnS:Cu and ZnS:Mn. Each of them is used alone, or several types of these randomly selected and mixed before use. Fluorescence spectra of fluorescent dyes have peaks outside the scope of the wavelengths of blue, green, red or the like and can be selected appropriately in accordance with the desired fluorescent spectrum.

The infrared fluorescent pigment to be used in the present invention, a pigment which is excited by infrared light (from about 800 to about 1200 nm) to emit visible light (about 400 to about 800 nm). The infrared fluorescent pigment is a fluorescent material that has an extremely unique mechanism of excitation. More precisely, many photons of infrared light having a small energy used for excitation of visible radiation. The excitation mechanism is classified in two types. One of them, which is observed in many of the major crystals with the use of Er3+, Ho3+(rare earth) and such as strengthening the Directors, is that the excitation is performed by multistage excitation in ion activator. Another type is that of Er3+Tm3+, Ho3+or such as the emission center is excited to a higher level through multistage resonance energy transfer from the sensitizer, i.e. multi-stage energy transfer resulting from the absorption of infrared rays by the sensitizer Yb3+. Specific examples of the sensitizer include YF3:Yb+Er YF3:Yb+Tm and BaFCl:Yb+Er.

Afluorescent dye to be used in the present invention, is preferably a pigment. The conventional examples of the pigment include inorganic pigments such as titanium oxide, zinc white, ultramarine blue, Prussian blue, chromium oxide and iron oxide; insoluble azo pigments such as ability, acetoacetic acid, aridization and pyrazolone azo pigment; soluble azo pigments such as pigment red C and brilliantined 6B; organic pigments such as copper phthalocyanine, chinagreen, Indigo pigments·thioindigo, indanthrene and pigments, perinon·perylene; and various pigments, which are used for conventional printing ink, such as carbon black.

Each combination of pigments, obyknovenny the second pigment, which should be used is preferably a pigment having little or no absorption in the infrared area and ultraviolet area. For example, when used as a black pigment that absorbs light across the area of the wavelength, it is preferably used in small concentrations (less than 1% of the mass). In addition, any of the above pigments preferably used in combination with a pigment that reflects light across the area of the wavelength, such as a white pigment. The use of white pigment effectively improves the ultraviolet fluorescent pigment and/or infrared fluorescent pigment, preventing ultraviolet light and/or infrared light, which is illuminated printing, coating, pass through the printed paper. In addition, normal color pigment, which should be used is preferably a pigment having a hue different from the wavelength of the ultraviolet fluorescent pigment and/or infrared fluorescent pigment. This combination led lighting printing ultraviolet radiation and/or infrared radiation provides the observer substantially different visual assessment. As a result, a large amount of information can be for the isano, forgery, alteration and falsification of information become difficult, and fake product can be easily identified.

Printing ink to be used in the present invention, can be obtained by mixing the required components and the dispersion of the pigment in the liquid substance according to the production technology, tailored to its printing method. Ultraviolet fluorescent pigment and the infrared fluorescent pigment easily settle in printing ink due to their large specific gravity. Therefore, they are preferably treated by repeated dispersion before use. Although the method of printing by means of printing ink to be used in the present invention is not strictly limited, printing ink is particularly suitable for inkjet recording, gravure printing, offset printing, letterpress printing, template print, and the like.

Examples of the printing paper (recording medium) includes securities, accounts, gift cards, cards, train tickets, entrance tickets, and the like; synthetic paper; and plastic films. Examples also include the product itself, which is easily imitated, and the container or carton of corrugated cardboard for goods, thus, the printed bamahane is strictly limited. Printing on printing paper (recording medium) may be such that various prints (information) are recorded by only the above printing ink, or may be such that separate the imprint is formed on part of the normal printing according to the method of the present invention. For example, securities may be formed by an ordinary printing ink, and only part of their impression can be formed according to the method of the present invention. Fluorescent pigment is relatively expensive. Problems associated with the cost can be avoided through the print side of the print, for example part of a large number of letters to be printed, using the method according to the present invention.

Then the support film is removed from the second film member comprising the first film member, the adhesive layer, and the magnetic layer having the form of said partial magnetic coating. The magnetic layer remains thereby on the first film member in a first structured pattern-like zone while said magnetic layer remains on the support film in a second structured pattern-like zone and is removed from the first film member along with the support film.

EFFECT: present invention provides a process for producing an enhanced security element and makes it possible to avoid undesirable grain formation and deformations.

FIELD: valuable documents.

SUBSTANCE: invention relates to valuable documents having the base and the protective strip-shaped element affixed to the base surface. The mentioned protective element serves the base authenticity or quality protection. The strips are made by transferring the transferable film, specifically the heat embossing film. The protective element includes at least two layers of synthetic material or lacquer with at least one optically active layer or structure between them, which produce changing optical effect depending on the illumination or the vision angle. The optically active layer and/or structure are placed at least in two definitely limited and visually changing surface zones set apart from each other. The strip, which is located outside the changing zones, is made invisible or practically invisible from the base surface. The strip doesn't change with the vision angle or the illumination outside the changing surface zones. The strip, while outside the visually changing zones, is transparently lustreless and/or conforms to the appearance of the base surface.

EFFECT: ensuring production of the valuable document with the protection element that is easily producible and applicable while having the protection properties.

SUBSTANCE: diffraction element has a grey-scale image from diffraction structures in the reflection layer, which are placed between a transparent layer and a protective layer of lacquer. The grey-scale image is divided into image elements, with at least one dimension less than 1 mm. The section of each image element is divided into a background image and the sample of the image element. At least through part of the surface of the grey-scale image pass streaks of the sample with a linear sample of thickness ranging from 15 mcm to 300 mcm and partially cover the background field and samples of the image elements. The linear sample is made from a band of the surface with structures of the sample and with thickness of the line in the range from 5 mcm to 50 mcm. The linear samples consist of letters, words, linear elements and pictograms. The structure of the sample differs from the first and second surfaces of the structure, at least, on one parameter of the structure. Thickness of the lines of the band of the surface in background fields is constant. Surface brightness of the image elements through the thickness of the lines of the surface streaks on the image element is controlled in such a way that, part of the area of the sample of the image element, not covered by the linear sample, is determined respectively by the surface brightness of the image of the grey-scale image in the location of the image element and with consideration of surface brightness of adjacent image elements.

EFFECT: provides for making a diffraction protective element, which demonstrates a grey-scale image and which is difficult to imitate or copy.
