The utility model provides a sign information carrier can make multiple shape, in the object (anti-fake goods) production process of for example wrapping paper, adds a plurality of sign information carriers to the object inside and/or surface, forms the marker of object. The markers are randomly distributed in the target object and/or on the surface of the target object to form a unique arrangement mode, and the unique arrangement mode can be used as a unique identifier in an anti-counterfeiting means. The utility model provides an identification information carrier, including the material that contains polar group in the material on its surface, polar group also calls hydrophilic group (group), including carboxylic acid group, sulfonic acid group, phosphate group, amino, quaternary ammonium group, hydroxyl, carboxylate and block polyether etc.. The polar groups in the material have hydrophilicity, so that the combination between the surface of the carrier and the fibers in the target object is tight and stable. The marking information carrier is characterized by water insolubility and surface hydrophilicity, which is helpful for the surface of the object to be flat and smooth, and the information carried by the marking information carrier can be more stably kept.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an identification information carrier 10 according to an embodiment of the present invention. In this embodiment the identification information carrier 10 is a hexagonal sheet structure, but in alternative embodiments it may also be triangular, quadrangular, star-shaped or irregularly shaped. The identification information carrier 10 comprises an upper layer 11 and a lower layer 12, wherein the upper layer 11 comprises water-based acrylic resin and other fillers, the lower layer 12 comprises carboxyl modified water-based butyronitrile latex and fillers, and therefore the whole outer surface of the identification information carrier 10 is hydrophilic, can be in close contact with pulp in paper pulp, is not easy to generate air bubbles with the pulp, can be firmly combined with paper pulp fibers after being dried, and is not easy to wrinkle. In this embodiment, the upper layer 11 and the lower layer 12 are both made of hydrophilic materials, but in some alternative embodiments, the upper layer 11 and the lower layer 12 may be the same substrate, and the surface of the substrate is coated with the same or different hydrophilic materials to form a hydrophilic coating, which can also achieve the aforementioned technical effects.
In this embodiment, the thickness of the identification information carrier 10 is 100 μm, and the single-sided surface area is 200mm2. Of course, the thickness and area are not limited to the above values, and the thickness may be any value between 15 and 200 μm, and the area may be 0.1 to 400mm2Any value in between. The preferable value range of the thickness is 30 to 100 mu m, and the preferable value range of the area is 0.5 to 100mm2. For example, the thickness thereof may be 15 μm, 50 μm, 85 μm, 100 μm, 200 μm, or the like; it may have an area of 0.1mm2、0.5mm2、1mm2、10mm2、50mm2、 155mm2、300mm2And 400mm2And the like.
The polymer resin is insoluble in water, and the polymer resin having a polar group has the characteristics of hydrophilicity and insolubility in water, and when the surface material of the identification information carrier 10 is the hydrophilic polymer resin, the identification information carrier 10 can be better incorporated in the paper fiber. In some other embodiments, one or a combination of two or more of styrene-butadiene latex, aqueous styrene-acrylic latex, aqueous polyurethane, aqueous polyamide resin, and rosin-modified aqueous resin may be used to fabricate the identification information carrier 10 or to coat the surface of the identification information carrier 10.
While the identification information carrier 10 shown in fig. 1 is of a two-sheet structure comprising an upper layer 11 and a lower layer 12, in some alternative embodiments, the identification information carrier 10 may also be of a single-layer structure, i.e., the main body of the identification information carrier 10 is made of only one mixed material, such as a mixture of carboxyl-modified aqueous nitrile latex and filler, or the main body of paper is coated with carboxyl-modified aqueous nitrile latex.
In some alternative embodiments, the identification information carrier 10 contains a security material. When the identification information carrier 10 is manufactured, the anti-counterfeiting material can be added into the mixture of the water-based polymer resin, and the molded identification information carrier 10 contains the anti-counterfeiting material. For example, when the identification information carrier 10 contains a fluorescent material, the identification information carrier 10 can fluoresce under ultraviolet; when the identification information carrier 10 contains a temperature-change material, the identification information carrier 10 exhibits different colors at different temperatures. Of course, the choice of the anti-counterfeiting material is not limited to this, and may be one or more of an infrared material, a laser material, a magnetic material, pearl powder, an optically variable material, and a microchip.
In further or alternative embodiments, the identification information carrier 10 is transparent or translucent or opaque. When the identification information carrier 10 is transparent or translucent or opaque, it may form a watermark effect in an object such as security paper through which a translucent or opaque window is visible. Moreover, the watermark effect formed by the identification information carrier 10 is different from that of a common watermark, because the orientation of the identification information carrier 10 on paper is random and cannot be reproduced by printing or copying, the watermark has a better anti-counterfeiting effect when applied to anti-counterfeiting products.
In further or alternative embodiments, the hardness, transparency, color, specific gravity and strength of the identification information carrier 10 can be set according to the actual needs, and the desired state is obtained by changing the respective filler components in its formulation. Fillers include, but are not limited to, one or more of calcium carbonate, titanium dioxide, barium sulfate, silica, kaolin, lithopone, pigments, and dyes. For example, when the identification information carriers 10 with different colors, transparencies and sizes are added to the anti-counterfeiting product of the anti-counterfeiting paper, the imitation difficulty and cost are greatly increased, and the anti-counterfeiting effect is better.
In further or alternative embodiments, the surface of the identification information carrier 10 is provided with an information identification. The information mark can correspond to preset information, and can be read by general equipment, special equipment or direct manual work, such as figures, symbols, characters, letters, numbers, two-dimensional codes, bar codes or computer codes.
