A kind of composite safe line
Technical field
The present invention relates to anti-fake material and field of anti-counterfeit technology, specifically a kind of composite safe line that can be used for bank note, marketable securities, ticket card card and similar articles.
Background technology
At present, in a lot of papery classes or similar article, anti-false sign need be set and improve its security performance,, through safety line is set it is identified easily, but be not easy to be copied or palm off like bank note, security, ticket, certificate etc.Safety line is widely used as a kind of anti-false sign; Generally be with PET (PETG, English name: polyethylene terephthalate, abbreviation PET; Be high polymer) the substrate bears anti-counterfeiting information, adopt fully buried or the mode of windowing combines with paper.The anti-counterfeiting information layer of safety line uses the false proof mode of magnetic code more, and the type of magnetic code has Hard Magnetic coding, soft magnetism coding and according to the coding that has or not setting of magnetic stripe, with the size of magnetic field intensity or coding of magnetic stripe width setup or the like.But; In the prior art; The magnetic code of safety line adopts single form more, as disclosing a kind of safety line that is used to improve paper safety among the Chinese patent document CN1715560A, comprises basic unit; Form an optical anti-counterfeiting Information Level and a magnetic anti-counterfeit Information Level in the both sides of said basic unit respectively, respectively be formed with tack coat in the outside of said optical anti-counterfeiting Information Level and said magnetic anti-counterfeit Information Level.In this technical scheme; Have only the realization of need encoding of magnetic anti-counterfeit Information Level, and said magnetic anti-counterfeit Information Level only adopts a kind of coded system, this single coded system is because its coded message is simple; Be easy to be cracked, therefore can not reach good antifalse effect.
Summary of the invention
For this reason; Technical problem to be solved by this invention is the false proof mode of safety line employing magnetic code in the prior art; Owing to only adopt a kind of magnetic code mode; Be easy to be cracked, antifalse effect is not good, thereby proposes a kind of safety line of using multiple magnetic code mode, having improved antifalse effect.
For solving the problems of the technologies described above; A kind of composite safe line of the present invention; Comprise the basic unit of at least one carrying magnetisable material, in said basic unit, be provided with at least two magnetic anti-counterfeit layers, on said two magnetic anti-counterfeit layers, be provided with non-interfering different magnetic code.
The width of said composite safe line is 1-3mm.
Said magnetic anti-counterfeit layer is arranged on the homonymy of basic unit.
Said magnetic anti-counterfeit layer is arranged on the both sides of basic unit.
Corresponding between the magnetic code of said a plurality of magnetic anti-counterfeit layers through AES.
Said magnetic false proof layer is the nanometer thin rete, is made up of the amorphous nano film.
Said nano thin-film layer thickness is 50-250nm.
The machine-readable signal of said nanometer thin rete has big Barkhausen's effect.
Said nanometer thin rete forms magnetic code through the variation of magnetic regions self size, adjacent magnetic regions gap size and amorphous nano film.
Said magnetic anti-counterfeit layer comprises the magnetic information layer, and said magnetic information layer comprises soft magnetosphere, hard magnetic layer or its combination.
Said magnetic information layer forms magnetic code through magnetic regions self size, adjacent magnetic regions gap size, magnetic coating thickness, magnetic field intensity and different magnetic materials.
Cover covering layer on the said magnetic anti-counterfeit layer.
The surface of said safety line sets gradually tack coat and protective layer from outside to inside.
The inboard of said protective layer also is provided with protection basic unit.
