Embodiment
Current smart card generally adopts printed words, pattern identification etc. to carry out anti-counterfeit recognition, some imitated enterprises easily spend little cost to copy fastener, be difficult to reach the false proof object of fastener, and dynamic optical to amplify film anti-counterfeiting technology be one of the most difficult imitated anti-counterfeiting technology in the world, the widespread use on the banknotes such as dollar at present of this anti-counterfeiting technology, if can apply it on smart card, effect false proof and attractive in appearance can be played simultaneously.
The utility model is for deficiency of the prior art, provide a kind of false proof smart card based on dynamic optical amplification effect, inner by the card of will dynamically amplify anti false film embedding smart card, the dynamic optical realizing smart card amplifies false proof, and the micro-picture and text dynamically amplifying anti false film can random sets itself, often opening card picture and text all can difference, can play effect false proof and attractive in appearance simultaneously, this anti-counterfeiting technology is difficult to copy, and antifalse effect is better.
A kind of false proof smart card based on dynamic optical amplification effect, false proof smart card comprises card 2, card 2 is made up of substrates multilayer film, card 2 upper strata is provided with perforate, be embedded with in perforate and dynamically amplify anti false film 1, dynamic amplification anti false film 1 upper and lower sides edge is coated with coupling agent, makes dynamically to amplify anti false film 1 and is fixedly connected with base film 2.
Dynamic amplification anti false film 1 comprises overlay 12, is arranged at the picture and text structure for amplifying layer on overlay 12 upper surface, and is arranged at the Antiforge layer on the downside of overlay 12; Integrated picture and text can be realized to the Antiforge layer bottom overlay by picture and text structure for amplifying layer to amplify, false proof to reach Dynamic Recognition.
Picture and text structure for amplifying layer can be microlens array structure 11, and microlens array structure 11 impresses curing mode by UV and takes shape on overlay 12 upper surface.
Antiforge layer is micro-picture and text array structure 13, and micro-picture and text array structure 13 impresses curing mode by UV (radiation curing) and takes shape on the lower surface of overlay 12, forms the fluted structure of tool, is filled with pigment in groove.Micro-picture and text array structure can realize amplifying under the effect of microlens array structure, can observe the false proof figure of dynamic amplification effect from the upper surface of card, and when the Angulation changes of observer, amplification figure there will be regular position and moves.The color of filler pigment can be other colors that are blue or that preset.
Wherein, microlens array structure and micro-picture and text array structure have micron order or nanoscale structures.Adopt the method for UV nano impression can efficient replication micro nano structure, stability be high, cost is low, is conducive to application implementation.
Wherein, Antiforge layer can be at the metal level of overlay 12 lower surface evaporation or dyed layer, or for being arranged at the base film that can carry out laser ablation containing dyed layer on the downside of overlay.Common metal layer is aluminium coated, and dyed layer can be ink layer.During making, first can design security pattern or word or symbol etc. on computers, then signal be inputed to laser pen, be etched according to the path locus set before by laser pen, the Antiforge needed for formation.
Wherein, the thickness of overlay 12 equals the focal length of microlens array structure, by adopting laser beam incident to false proof smart card, the focal length of microlens array structure forms superfine focal spot, make luminous point place luminous energy comparatively strong, metal level or dyed layer are undergone phase transition or ablation and variable color.The irradiation position of mobile laser beam, forms space diagram, and these space diagrams near focus point, thus are formed personalized figure write by microlens array structure imaging.Can observe Spatial distributions figure from the upper surface of card, when viewing angle changes, graph position moves.
Picture and text structure for amplifying layer also can be coated overlay upper surface by the mixed liquor of glass microballoon and resin and be formed.Substitute microlens array structure with glass microballoon, the mixed liquor containing glass microballoon and resin is applied to transparent plastic film, then evaporated metal layer or coating dyed layer on the lower surface of overlay.Will containing layer on surface of metal downwards, glass microballoon faces down, and becomes can be used for the false proof smart card of personalized ablation with other base film laminated compounding.Above false proof smart card, go out personalized motion graphics with laser ablation, can the content such as personalized ablation dynamic two-dimension code, word and figure, specifically do not limit.
Wherein dynamically amplify anti false film and can be the materials such as PC (polycarbonate), PET (polyethylene terephthalate), PVC (Polyvinylchloride) transparent membrane, concrete material needs according to use and determines.
The empty limit of 1mm-3mm is generally reserved at dynamic amplification anti false film edge, for boning with levels base film.Empty limit size also can be 1.5mm, 2mm, 2.5mm etc., does not limit at this.
Based on a method for making for the false proof smart card of dynamic optical amplification effect, concrete steps are as follows:
(1), according to use need to choose overlay, and at the two sided coatings coupling agent of overlay;
(2), in the mode that overlay upper surface is solidified by UV impression with the metal die containing microlens array or medium mould, by the microlens array transfer replication of die surface to overlay upper surface, form microlens array imaging structural sheet, the surrounding of overlay is left a blank limit in advance;
(3), by the mode of the convex type mould containing micro-picture and text array structure by the solidification of UV impression, graphic structure is copied on overlay lower surface, form the fluted structure of tool, filler pigment in the trench, form coloured micro-picture and text array structure, the surrounding of overlay is left a blank limit in advance, and formative dynamics amplifies anti false film;
(4), at least one layer film in upside of base film the first through hole is opened in any position, and the first clear size of opening is less than or equal to the size of dynamically amplifying anti false film, and this thin layer is as the upper surface layer of intelligent cards; On the downside of upper surface layer, offer the second through hole with the first through hole corresponding position, the second clear size of opening is with dynamically to amplify anti false film consistent, and dynamically amplify anti false film in order to be embedded location, upper surface layer is in order to spacing dynamic amplification anti false film;
(5), by substrates multilayer film with dynamically amplifies anti false film stack successively combine after be put in laminating machine equipment and carry out lamination treatment, finally form the false proof smart card being integrated with dynamically amplification anti false film.
Step 3 is evaporated metal layer or dyed layer on the lower surface of overlay, or the inner base film that can carry out laser ablation containing dyed layer is set in the downside of dynamically amplifying anti false film, after false proof smart card completes, above false proof smart card, etch the word, symbol or the pattern that set with laser incising, form micro-picture and text array structure.
