(57) Abstract:The invention relates to a method of recording information, in particular the creation of a protective film elements, intended for protection of securities and other products from fakes, erasures, corrections, and copy. The technical result of the invention is the production of media with a high degree of protection through the use of the individual characteristics of the devices to create media with a high degree of uniformity of the dimensions of the labels on the media. Film media to protect products and documents from counterfeiting and copying is made by irradiation of the polymer film by the flux of heavy ions, followed by exposure of the irradiated film to UV radiation and etching of the polymer film in a solvent. Exposure and exposure of the polymer film can be spatially modulated by the flux of heavy ions and UV radiation, in particular by imposing masks. The use of the proposed method to obtain media information that has been concealed and visible macro - and micro-image, with the size of the micro elements from 0.01 μm or more. 12 C.p. f-crystals, 4 is radialnykh film elements, intended for protection of securities and other products from fakes, erasures, corrections and copy.The greatest progress in the technique of recording and playback of high-frequency images made in the application of holographic and laser methods. These methods have found wide application in the last 20-30 years.A known method of manufacturing a valuable document according to which at first make a base of paper or paperboard  To obtain the structure of the optical labels, which causes diffraction, refraction or reflection of the feeding of light, on this basis put a transparent layer or a layer formed by printing the ink on which recorded information about authentication, in the form of optical embossed marks obtained by embossing under pressure or heating diffraction master grating or hologram.There is also known a method of non-repeatable product designations to prevent copying or forgery by drawing on a sheet or film holographic image with the subsequent insertion of the sheet or film in a product or its packaging 
The image may be entered in the product itself or may be a holographic zobrazeniwith copy can be a very affordable means of lasers, holographic stands, pressing devices, widely produced in different countries. In addition, when large numbers of securities is technically difficult to provide protection in this edition of one security relative to another in the context of the use of this technology, i.e. it does not provide individual protection document.There is a method of marking documents, provided the individual code in the form of a perforation pattern which is recognizable irregularities. The perforation is performed with the laser beam on the basis of the usual pattern, with the control of the laser is performed using a computing machine so that each perforation has an individual irregular, depending on the original value 
In this way it is possible to make only the circulation volume of products, since the rate of pointwise laser burning significantly below methods for forming labels simultaneously over the entire area of the media. This method has limitations on the size of the smallest diameter holes at a maximum depth associated with the diffraction limit of the wavelength of the laser, its power and actinically media, which is especially I, according to which sheet media, at least on one side is applied to the reflective layer. The reflecting layer is applied to the group of grains, resulting in the surface layer has a varying reflectivity. Mark formed by groups of grains can be read by a machine 
This way to protect documents from tampering has some significant limitations in its application. For example, it is difficult to provide high resolution due to the mounting of the grains in the process of grinding and coating, increasing the dispersion increases the spectral width of the image in the region of low spatial frequencies.A known method of manufacturing a safety feature in the form of a wire or ribbon, put in documents 
According to this method, the polymeric film creates a matte finish, which, in turn, created the slits in the form of characters and/or patterns. At least coincident with the slits plots applied coloring and/or luminous substance, making the characters and/or patterns in the respective light conditions become visible on the matte surface.In this way the safety of ale and the EP image matte coating is deposited over the low-frequency image as a transparent area, which can be filled with dye and/or fluorescent substances. Thus, this method does not implement the resolution of the medium-level high-frequency properties of the matte layer.The aim of the invention is to provide a method of manufacturing a film carrier information for the protection of documents and products from counterfeiting and copying, which allows to increase the degree of protection of documents and products through the use of the individual characteristics of the devices for media creation, the high degree of uniformity of the dimensions of the labels on the media. Taking into account the possibility of using the proposed method in the production of large-circulation volume of the media.In addition, the aim of the invention is the ability to create on the same media as the visible image and the latent located on one side of the film carrier, and on both sides. Taking into account the possibility of saving a latent image (i.e., to render it) for several years.Finally, the aim of the invention is the possibility of introducing changes and amendments in the image tag, both in micro and macro.Irradiation of the polymer film can be proscrastination heavy ions, e.g., carbon, chlorine, nitrogen, oxygen, argon. This spatial modulation, in particular, can be created by the mask.The irradiation of ions allows you to create a latent image on the film, which can be stored for several years before his rendering, which is carried out by exposure to UV radiation and etching of the polymer film before the occurrence of holes in it.The type of ions and their energy is selected calculated or experimentally depending on the capabilities of their passing through the entire thickness of the polymer film.In order to enhance the protective function of the carrier of heavy ion irradiation is carried out in accordance with the specified treason the hydrated case the angle between the direction of motion of the ions and the surface of the film can be chosen constant. This aims to strengthen the protective functions of the media, is the potential exposure of the polymer film from both sides.The irradiation of the polymer film heavy ions exhibiting her proscrastination UV radiation can be carried out, in particular, through the mask.The proposed invention is illustrated by drawings, where Fig. 1 shows the operation of irradiation of the polymer film heavy metal ions; Fig. 2 - the operation of exposing the polymer film to UV radiation; Fig. 3, the operation of the etching, and Fig. 4 media labels, General view.The method can be carried out as follows.As a starting material for the production of carrier selected segment of the polymer film 1 (Fig. 1). As the polymer film can be used polyethylenterephtalate film.The polymeric film is placed in the cyclotron irradiation by heavy ions 2 (Fig. 1A). Irradiation of the polymer film is performed on the cyclotron heavy multicharged ions. First of all it ions of carbon, oxygen, nitrogen, argon, chlorine. Depending on the for example, for films with a thickness of up to 20 microns can be applied to almost any of the above ions. The choice will be determined by the amount of energy their acceleration (with the same value, for example, for ions of oxygen and argon energy acceleration is 32 and 80 MeV, respectively). For films thicker the choice is limited almost ions of oxygen and argon, as their mileage ranges from 40 to 180 μm.Due to unilateral or bilateral irradiation in the material film formed tracks 3, which form the first latent image.The irradiation can be spatially modulated by heavy ions for the media hidden microsurgery. Spatial modulation of heavy ions is achieved in various ways, in particular, installation of the cyclotron in the flow path of heavy ions block the amplitude of the spatial modulation 4 (Fig. 1B) and/or, for example, before installing a polymer film mask 5 (Fig. 1B).When used in the cyclotron unit amplitude of the spatial modulation 4 ions are irradiated to the entire surface of the polymer film. In this case, the polymer film formed sections with different Nosti polymer film, and only in those places where the film was open to exposure.The heavy-ion irradiation can also be carried out at an angle (Fig. 1), the surface of the film, other than a right angle or for the changing angle of the irradiation process. As a result, the tracks produced in the film, are also under some constant angle or under changing on the film surface angle. This can also be applied spatial modulation of the flux of heavy ions, the above-described methods, in particular by using a mask (Fig. 1D).Such irradiation of the polymer film allows you to get a first latent image, which result from the use of specific cyclotron and method of spatial modulation of heavy ions is almost impossible to repeat.After heavy ion irradiation of the polymer film is subjected to exposure to UV radiation 6 (Fig. 2). As a result of exposure to UV radiation irradiated by heavy ions of the polymer film around the tracks formed by heavy ions, there are extensive areas of degraded material 7 (Fig. 2A), sensitized to subsequent etching. Thus, a second latent image.In the case when the heavy-ion irradiation was carried out not at a right angle, extended the area of degraded material are located along the tracks of heavy ions, and thus, are also arranged at a given angle at a given point of the polymer film (Fig. 2G). When using the mask, you can get hidden sensitized to the etching of microsurgeries label having an extension region destructured material film located at a certain angle (Fig. 2G).The visualization of the label in the form of perforations is carried out by etching the film, for example, a 20% solution of sodium hydroxide. For neutralization of sodium hydroxide polymer film is then treated with acetic acid, washed with distilled water and dried.In the etching on the surface of the polymer film was formed recesses and openings 10 (Fig. 3) having a diameter of from 0.01 μm and Bo the I heavy ions and exposure to UV radiation, including a target at a given point of the medium, the inclination of the grooves and holes. Thus obtained visible micro - and microsurgery (Fig. 4).Microsurgeries may be from a variety of patterns, symbols, numbers, letters, depending on the method of spatial modulation of heavy ions and exposure to UV radiation, for example, in the form of letters (Fig. 4A).Micro-image (Fig. 4B) represents a set of holes and recesses with the media specified diameter distribution, the slope with respect to the surface of the polymer film and the frequency distribution on the surface.The resulting media can be used to protect any document, for example, identity cards by gluing it on this card so that part of it is not completely overlaps the photograph of the holder, and the other part would have to place the signature. After the signature of the owner of the surface of the carrier may be coated with a thin layer of varnish, which fills available openings in the carrier (the other holes were filled with ink when signing).Given the high density hole location on the media is so, to improve in the area of media or playback is not possible. When considering the image of the label under the microscope you can see the micro-image (increase of up to 10xand images of individual sets of holes with the same diameter from 0.01 μm (increase 1350x). For the automatic determination of the identification signs of the label on the media read through the microscope (magnification 40x) CCD camera and enter the image in the personal computer. With it quickly and effectively determine the size of the holes, the density of their distribution and range of spatial frequencies, which enables the company to identify and map identification signs. The advantage of the proposed method of manufacturing a film carrier of information is the fact that the labels are established in the form of holes and recesses, the range of sizes which is in the range from 0.01 μm or more in diameter on the surface of the carrier that can be played by known methods impossible. In addition, their spatial distribution on the film statistically can match the features of the device exposure, for example, aberration of the magnetic system of formation of the ion beam, the design of e such a cyclotron, which would give the same static distribution of ions on the surface of the polymer film.In addition, the use of heavy-ion cyclotron allows a wide range to vary the size of the holes and recesses labels as their diameter on the film surface, and the depth inside the material, which creates additional opportunities protection of information through labels, as known methods of reproduction impossible.An important advantage of the method is that the first latent image marks formed on the film heavy ions at e irradiation in a cyclotron, can be visualized directly after irradiation, and after a considerable amount of time up to several years, which can be used to create a hidden protection.Irradiation by heavy ions provides the ability to get labels made of holes and recesses with a high degree of uniformity in their geometrical dimensions. This unique property of this process allows you to better protect the protected document from forgery or patch.With exposure to UV radiation, you can make changes and additions in image tags. As well as nlany during exposure to UV radiation is possible only if the exact knowledge of the location of the first latent image, which is very important when multi-stage protection information.Etching the polymer film with the help of sodium hydroxide or potassium renders the image tag, and depending on the modes etching (time, concentration, composition and temperature of the solution), you can modify the geometric dimensions of the holes and recesses constituting the label, but not their coordinates. Selective etching (through the mask) gives additional opportunities to variations protection with labels.If you specify a spatial modulation of heavy-ion irradiation, and this causes a change in the speed of the ions and their directions, you can make a label for additional protection in the form of statistically given distribution of holes and recesses on the polymeric film. Because these items have labels micron size, and their surface density is 105-1010items on 1 cm2then play this label in other ways extremely difficult.Given the technological complexity of the formation of the label, the first step in trying erasures or copy may be the definition of the topology of an arrangement of apertures and recesses on a polymer film that cheap modern descriptions of their location, so as holes and grooves are in the amount of film output on one or both sides. Therefore, to accurately describe it is necessary to have a Multiview stereoscopic image. This task seems to be rather complicated scientific and technical problems. However, even after its decision occurs no less difficult problem how to play tag.When exhibiting spatially modulated UV radiation is the possibility of translation of the first latent image on the second latent image tags at the same time by making amendments or modifications, which for some reason was impractical to perform on the stage of formation of the first latent image. For example, during the UV exposure is more suitable to modulate the high-frequency component of microsurgery label than at the stage of exposure.In the irradiation process with the aim of expanding the capabilities of the media can be created microsurgeries label, composed of microimages in the form of perforations and microglobuline. For this irradiation is carried out through a mask, forming microsurgeries. With a mask you can get labels with macro is trebuetsya small optical zoom) and sub-micron image (in this case, when the reading optical or mixed (optical and electronic) increase 1000x-1500x.In many cases, you want the media to protect products and documents, working in the lumen, for example, plastic cards with holes, certain types of permits, certificates and tickets. In some applications, the carrier is applied to the mirror reflecting surface and actually works against the light. The most effective media, working in the lumen, if the label is made of holes, as the readout light flux passing through the apertures will not be scattered by the material medium, which occurs when the label is made in the form of recesses.A significant advantage of the proposed method over the known is the possibility of the formation of the marks from the recesses and holes located at an angle relative to the film surface, which is achieved by irradiation of heavy ions with a given change in the angle between the direction of propagation of heavy ions and the surface of the film, in particular, this angle can be chosen constant.The change in the value of the orientation angle of the holes and recesses of the labels relative to the surface of the film gives the enhancement of protective functions of the media due to the almost complete from the ability to create labels from the holes and recesses separately or simultaneously on both sides of the polymer film. This is achieved by heavy ions irradiation is carried out from both sides.The invention can be used to create the following papers and other documents proposed to the protection offered submicron remedy: banknotes, passports, bonds, shares, promissory notes, cheques, plastic cards, identity cards, passes, tickets, banking documents, legal documents, diplomas, certification and licensing labels and certificates, labels, lottery tickets, phone cards, etc.In addition, the proposed film carrier can be fixed by any known method suitable for polymer films on various products to confirm their authenticity. For example, it may be pre-recorded audio or the video cassette with the tape pasted on its packaging. 1.
