Description
Technical field
The present invention relates to a kind of anti-counterfeiting line, and in particular to a kind of preparation method of the micro-nano false proof silk thread of diffraction.
Background technology
Anti-counterfeiting line is a kind of bar material, national high applied to banknote, marketable securities, the entry and exit pass, visa etc.
Hold anti-counterfeit field；Selectable, anti-counterfeiting line can be bending, or knit into inside bank-note paper so that banknote has additionally
Antifalsification.As example, a kind of earliest form of anti-counterfeiting line is made up of the reflective foil that banknote surface is transferred to by brand
(GB2119312A).This reflection foil prevents counterfeit money from being printed for example, by printing machine, PC printing machine and duplicator etc.
The duplication of journey.Existing many anti-counterfeiting lines are easily imitated, because these anti-counterfeiting lines are only carved with text or numeral is made
For anti-counterfeiting mark, these embedding quarters or micro- print can not produce high-resolution image, larger loss easily brought to user.
The content of the invention
A kind of false proof silk thread of micro-nano diffraction is provided the invention aims to overcome the deficiencies in the prior art.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of false proof silk thread of micro-nano diffraction, it includes

And the holographic information layer that is in contact with the PET base material layer of bottom surface and be embedded in polymer protection layer and be formed at institute
The metallic aluminum on holographic information layer is stated, the metallic aluminum upper surface is formed with micro-nano diffraction grating.
Optimally, width≤0.8 millimeter of the false proof silk thread of micro-nano diffraction.
It is yet another object of the invention to provide a kind of preparation method of the micro-nano false proof silk thread of diffraction, it includes following step
Suddenly：
(a) micro-nano diffraction grating microstructure figure is designed using computer software；
(b) by designed micro-nano diffraction grating microstructure figure corresponding record to carrier, then developed；
(c) silver mirror reaction is carried out in carrier surface, forms metal layer；
(d) metallization mirror image corresponding with carrier surface is formed on metallic aluminum surface；
(e) cutting edge is carried out to metallic aluminum, is then compressed in PET base material layer and is formed the one of metallization mirror image
Face outwardly；
(f) fixed point is in metallic aluminum surface printing fluorescent ink, and drying forms security pattern；
(g) the etching liquid formation defect corresponding with security pattern, drying are coated with metallic aluminum surface；
(h) on PET base material layer surface, coating high polymer material makes it cover fluorescent ink, is cut and is wound after solidification
Collect.
Because above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：The present invention is micro-nano to spread out
False proof silk thread is penetrated, on the one hand micro-nano diffraction grating is formed with metallic aluminum upper surface, on the other hand in polymer protection layer
The holographic information layer being in contact with PET base material layer is inside embedded at, so can form clear under magnifying glass using holographic information layer
Clear complete word, and seven color cangiante lustre formation multiple anti-fake work(are shown under specific light using micro-nano grating
Energy.
