Description
Technical field
The present invention relates to anti-counterfeiting technology, particularly relate to a kind of anti-fake material and preparation method thereof.
Background technology
In existing skill counterfeit-proof tech, mostly using watermark, colored fibre, fluorescent ink printing, microdot or the body of small mark and random distribution etc. as counterfeit protection measures.
Such as, prior art 1, Chinese patent literature CN102108653A, disclosed a kind of lamellar anti-fake material, described lamellar anti-fake material uses the polymorphic structure beyond square；And described lamellar anti-fake material is made up of following layer structure: the false proof carrier layer of papery, the false proof carrier of wherein said papery is to be compounded by least two fiber to manufacture the paper obtained；And false proof layer.Also disclose the preparation method of described lamellar anti-fake material and the cheque paper containing this lamellar anti-fake material.The lamellar anti-fake material of the present invention can obtain and be provided simultaneously with the multi-level anti-fraud functional cheque paper such as naked eyes identification, the most machine-readable, analysis expert.
For another example, prior art 2, Chinese patent literature CN104610812A, disclosed fluorescence silicon nano particles as the application of anti-fake mark, are prepared fluorescence silicon nano particles by silicon source, the fluorescence silicon nano particles obtained are used as anti-counterfeiting ink to prepare security pattern.Owing to nano silicon particles has good photoluminescent property, quantum yield is high, and storage stability is good, has good excitation wavelength dependency, and the security pattern of preparation can show the light of different colours under the illumination of different excitation wavelengths, can play good antifalse effect.
For another example, prior art 3, Chinese patent literature CN101673341A, disclosed in the present invention relates to anti-counterfeiting technology, particularly relate to a kind of anti-counterfeiting method of micro-points.The method comprises the following steps: (1) provides a kind of microdot；(2) provide a kind of glue, microdot is mixed among glue；(3) the mixed atomarius glue of point on carrier；(4) solidified glue；(5) glue of taking pictures drips, and forms original Contrast's picture；(6) original Contrast's picture is stored in background data base；(7) fake certification glue of taking pictures drips, and is formed by than picture；(8) read background data base original Contrast's picture, and compared than picture, make the true and false and judge；Wherein, the glue of taking pictures described in (5th) step drips, and takes pictures for amplifying；Fake certification described in (7th) step glue of taking pictures drips, and is also to amplify to take pictures.The present invention provides one the most imitability anti-counterfeiting method of micro-points.Corresponding, Chinese patent literature CN102267287A discloses the preparation method of a kind of similar a kind of microdot anti-counterfeiting stamp and and realizes the device of the method.The preparation method of microdot anti-counterfeiting stamp comprises the following steps: S1, it is provided that a kind of microdot label, it is provided that a kind of ink；S2, mixed ink, will mix homogeneously with ink by microdot label；S3, it is provided that at least two shower nozzles, it is provided that object；S4, injection, by shower nozzle, the ink being mixed with microdot label is sprayed to subject matter；S5, is dried the ink being mixed with microdot label；In course of injection, mixed ink step is carried out continuously, mixes ink, completes in totally enclosed fluid path to shower nozzle ink supply, injection.The present invention provides and is difficult in a kind of course of processing be mixed into the preparation method of impurity, in real time the microdot anti-counterfeiting stamp that holding microdot is evenly distributed in ink and realize the device of the method.
For another example, prior art 4, Chinese patent literature CN1350274A, disclosed a kind of anti-fake mark containing most small marks or pattern and forming method thereof, with the anti-fake mark containing most micro pattern marks, reach and identify article genuine-fake and prevent the application forged.Object qualification method is according at least one unique tag formed in object, it contains most micro pattern or mark, and together in labelling in the way of random combine, with as a comparison, identify method, and have prevent other people from forging and can be easily achievable identify and identify and contrast effect.
For another example, prior art 5, Chinese patent literature CN105489112A, the present invention relates to anti-counterfeiting technology, particularly relating to a kind of anti-fake material and preparation method thereof, anti-fake material includes the monocrystal silicon module of lamellar, and monocrystal silicon module has void region, anti-fake material also includes metal module, and metal module is embedded in described void region；The preparation method of anti-fake material, by the plating of face on the glass substrate adhesive layer, plating sacrifice layer, plating monocrystalline silicon layer, coating light binding, exposes, develops, cleans, etching monocrystalline silicon layer, second glue spreading, exposes, develops, cleans, plating module, clean light binding, etching sacrificial layer, clean and filter；The present invention provides one to have many materials, relief anti-fake material and preparation method thereof.
But, the most listed above 1 to 4, the composite fibre of prior art, fluorescence silicon nano particles, microdot or the body of small mark and random distribution etc. are as counterfeit protection measures, it it is not the effect being possible to prevent other people to forge as disclosure describes, progress along with science and technology, these technological means all can inexpensively be copied, that can not copy only has the background data base described in prior art 3, but back-end data is the most dangerous, the data base of enterprise is easily subject to assault, and need communication security guarantee, the most undesirable.Above-mentioned prior art 5, although overcoming the defect of prior art, but metal and single crystal silicon material cost are the highest, process costs is the highest, especially etches monocrystalline silicon layer, needs expensive ICP equipment, for domestic consumer, implements pressure bigger.Thus, the anti-fake material of prior art and counterfeit protection measures all have potential safety hazard more or less, and the cost without potential safety hazard is high, need constantly to weed out the old and bring forth the new, constantly improve.
