Abstract

The utility model relates to laser holographic anti-counterfeit paper, which adopts any papery paper as a papery base layer. The paper is firstly coated with an organic resin layer as a reflecting layer. The reflecting layer is secondly coated with an inorganic medium film with high reflecting rate by a physical or chemical method and the film is pressed with anti-counterfeit patterns or pictures as a pattern layer. The anti-counterfeit paper of the utility model can be directly used for the anti-counterfeit purposes of stamps, securities, tickets and other certificates, such as ID cards, passports, etc. The utility model can also be used for articles requiring disposable entire package for the anti-counterfeit purposes.

Description

Antiforge laser holographic paper

Antiforge laser holographic paper relates to the novel antiforge laser holographic paper of a kind of structure.

At present, draw together papery basic unit, adhesive-layer, aluminium film embossed layer and plastic membranous layer with paper as the antiforge laser holographic paper bag of substrate.Wherein security pattern is to extrude on aluminium film embossed layer by the special metallic plate of laser holography that impression is different, different (CN.94236443) that form of the depth, perhaps is compounded on the aluminium film embossed layer or (CN.93107856) that form on the plastic membranous layer by laser holographic molding copying image technology.The realization of above-mentioned technology will adopt suitable papery as papery basic unit on the one hand, on the other hand will be by more loaded down with trivial details manufacture craft with adhesive-layer, aluminium film embossed layer and plastic membranous layer by bonding or be compound in the papery basic unit, the production cost of cheque paper is higher.

The utility model provides a kind of novel structure, and is simple, easy to make, can select the antiforge laser holographic paper of the paper of any papery as basic unit for use.

The utility model is by papery basic unit, the reflecting layer, and the security pattern layer constitutes.Papery basic unit can select the paper of any papery for use, applies organic resin in the above as the reflecting layer, and the material in organic resin reflecting layer is polyurethane or amino resins or alkyd resins.Adopt physical vapor deposition (steam method as heat, electron beam steams method, magnetron sputtering) method or chemical coating process to apply the inorganic dielectric film of individual layer high index of refraction on the organic resin reflecting layer, the material of inorganic dielectric film is Tio ₂Perhaps Zro ₂Perhaps Tio ₂+ Zro ₂Last antiforge laser holographic pattern and/or the image suppressed on the inorganic dielectric film of high index of refraction made the antiforge laser holographic drawing.

Advantage of the present utility model is; The optical effect of cheque paper is good, is used to can be used for the entire package by false proof thing after the printing, can be clear that by the apparent details of false proof thing, can be clear that the antiforge laser holographic pattern on the cheque paper behind the translation-angle again, reaches false proof purpose.The cheque paper that the utility model provides can be with any papery as papery basic unit, and is simple in structure, less demanding to production equipment, so production cost is low, has broad application prospects.

Accompanying drawing is the utility model embodiment, wherein;

Fig. 1. the utility model structural representation,

Fig. 2. the utility model security pattern layer cross section schematic diagram.

The utility model will be further described according to above-mentioned accompanying drawing;

Embodiment one

Antiforge laser holographic paper adopts stamp to use paper as papery basic unit 3, and coating one deck amino resins reflecting layer 2 on papery basic unit 3 applies individual layer high index of refraction Tio by chemical coating process then on amino resins reflecting layer 2 ₂Inorganic dielectric film is at last at Tio ₂Compacting antiforge laser holographic figure on the inorganic dielectric film.Shown Tio among Fig. 2 ₂The groove 4 of the formation figure that is carved with on the inorganic dielectric film, thus incident light reflects the back because disappearing mutually and superposeing of phase of light wave forms colored false proof figure through groove 4, makes false proof stamp.

Embodiment two

Select for use ticket with paper as papery basic unit, at first apply one deck polyurethane resin reflecting layer on paper at ticket, again on this reflecting layer with chemical coating process coating one deck Zro ₂Inorganic dielectric film, compacting antiforge laser holographic pattern on inorganic dielectric film makes Counterfeit ticket at last.

Embodiment three

Select for use package paper as cheque paper papery basic unit, at first on package paper, apply one deck alcohol ammonia resin reflecting layer, on this reflecting layer, apply one deck Tio with chemical method ₂+ Zro ₂Film is at last at Tio ₂+ Zro ₂Compacting laser anti-counterfeit figure makes the packaging cheque paper on the deielectric-coating.

Embodiment four

With common papery is the papery basic unit of cheque paper, applies one deck polyurethane resin reflecting layer on common papery earlier, uses magnetically controlled sputter method sputter one deck Tio again on this reflecting layer ₂Deielectric-coating is at last at Tio ₂Suppress the antiforge laser holographic figure on the deielectric-coating, make the cheque paper of common papery.
