Abstract
The utility relates to a multilayer anti-counterfeit paper, comprises at least two layer of pulp layer and an anti-counterfeit interlayer which is arranged between the two adjacent pulp layers and contains artificial DNA fragment with anti-counterfeit information. Due to the artificial DNA fragment contained by the anti-counterfeit interlayer, the special anti-counterfeit information is carried by the artificial DNA fragment. The utility not only has obvious color interlayer anti-counterfeit effect, but also can recognize the truth and falsehood, the information of product producing and logistics, etc, by detecting with special instrument. The utility with high reliability is difficult to imitate, has a very good anti-counterfeit effect.
Description
[technical field]
The utility model relates to a kind of cheque paper, is meant a kind of Multi-layer anti-counterfeit paper especially.
[background technology]
At present, upward stamp some anti-counterfeiting marks on the surface of pulp layer reaches false proof purpose to cheque paper usually, and this anti-counterfeiting technology comparatively speaking, and is comparatively simple and easy, more easily by imitated, and can't reach antifalse effect.
And the artificial dna anti-counterfeiting technology is a high-tech artificial creature anti-counterfeiting technology that comes into one's own day by day, the way of DNA anti-counterfeiting technology is: utilize 26 kinds of chemical elements of nature different modes be combined to form several hundred million meter DNA code signals, after carrying out certain technical finesse, can form the stealthy material that combines with various materials, can make various color pigments and throw in false proof layer.Like this, all will contain different minim DNA password signs in every a piece of paper of producing.This DNA encrypted message can be detected by the detector of special use and carry out truth identification, and the producing and selling link comprehensive information tracking and managing that carries out product.This technology can be widely applied in food, medicine cosmetics and the pigment and go, and its utmost point is expected to substitute traditional antifalsification label and laser anti-counterfeit method.DNA is false proof to be to have utilized the matter DNA of Different Individual to have the principle of the coding structure that has nothing in common with each other, and makes anti-counterfeiting mark contain certain and determines DNA of individual.Up to the present, do not find anti-fake product that the DNA anti-counterfeiting technology is combined with cheque paper as yet.
[utility model content]
Technical problem to be solved in the utility model is: a kind of Multi-layer anti-counterfeit paper is provided, and its false proof reliability height is difficult for by imitated, and antifalse effect is better.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: provide to comprise two-layer at least pulp layer, be provided with the false proof layer of the artificial dna fragment that comprises anti-counterfeiting information between adjacent two pulp layers.
Further improvement in the technical proposal is: described false proof layer is literal, pattern or the plane of spraying.
Further improvement in the technical proposal is: described pulp layer is more than three layers or three layers, and correspondingly is provided with two-layer or two-layer above false proof layer.
Further improvement in the technical proposal is: described false proof layer is colored false proof layer.
The beneficial effects of the utility model are: owing to include the artificial dna fragment in false proof layer, carry special anti-counterfeiting information by the artificial dna fragment, can identify the true and false under instrumentation detects, the reliability height is difficult for by imitated, and antifalse effect is better.
Below in conjunction with accompanying drawing the utility model is described in further detail.
[description of drawings]
Fig. 1 is the cutaway view of the utility model Multi-layer anti-counterfeit paper.
[specific embodiment]
The utility model provides a kind of Multi-layer anti-counterfeit paper, and it comprises two-layer at least pulp layer and is located at false proof layer between the adjacent two layers pulp layer.In embodiment as shown in Figure 1, it comprises three-ply paper slurry layer 1,3,5, correspondingly is being respectively equipped with the false proof layer 2,4 that comprises the artificial dna fragment with anti-counterfeiting information between adjacent two pulp layers 1,3 and the pulp layer 3,5.Described false proof layer 2,4 can be the literal or the pattern of spraying, is even the simplest uniform planar coating structure.Described false proof layer 2,4 can be colored or monochromatic false proof layer.
When making the utility model Multi-layer anti-counterfeit paper, described artificial dna material can be blended among the pigment equably by special process, and then will contain the surface that artificial dna pigment is sprayed at pulp layer 1,3,5 under given conditions, and form Multi-layer anti-counterfeit paper.
In the time of need distinguishing true from false, the consumer tears corresponding pulp layer 1,3,5 and can see and contain DNA anti-counterfeiting information fragment.Then needn't destroy under the paper prerequisite and can detect as detecting with detector; But in particular cases both made paper burn till ashes at the utmost point and also detected to entirely accurate correct result, for judicial expertise provides foundation.
Owing to be to carry special anti-counterfeiting information by this high-tech product of artificial dna, remedy the false proof deficiency of a line, and under instrumentation detects, identified the true and false, reliability is higher, extremely is difficult for by imitated, and antifalse effect is even more ideal.
