Description
Technical field
The present invention relates to optical anti-counterfeiting field, relate in particular to a kind of optical anti-counterfeit element and adopt the anti-fake product of this optical anti-counterfeit element.
Background technology
Light becomes coating technology, and to be widely used in the public of the contour false proof securities of banknote false proof, it can present different colors under different viewing angles, be convenient to describe, be easy to public's identification, and cannot utilize the electronic equipments such as camera, scanner, printer imitate or copy, so there is very high anti-counterfeit capability.
But because light sell of one's property product are applied the time that has had many decades, simple light becomes coating technology can not meet the demand in false proof field well.Light becomes coating and becomes and join peer to peer technology and combine and new anti-counterfeiting characteristic is provided with hollow out, holography, light.For example, in patent US5766738, US6114018 and US7729026, propose to become matching characteristic by selecting suitable light change thickness of coating and color to realize light.Five layers of light that Switzerland SICPA company has a symmetrical structure by pulverizing become coating structures and form optically variable pigments (OVP), and then obtain photochromatic printing ink (OVI), and it can be combined with printing technology in the multiple banknote in the ，Bing world and be widely applied.As further developing of OVI, at existing light, become and in structure, increase one deck magnetosphere just to have formed light metamagnetism ink (OVMI) be SPARK technology, this technology makes the OVMI particle can be along magnetic induction line direction oriented alignment by induced by magnetic field, thereby forms specific picture and text structure.In OVMI, particle is arranged while having specific rule variation, can produce the optical signatures (asking for an interview patent US7517578B2) such as innervation, convergent-divergent.But because the oriented alignment of light metamagnetism particle need to rely on magnetic field, therefore be subject to the restriction of magnetic field shape, can not design arbitrarily shape, and need specific orientation equipment and technique.In order to overcome this shortcoming, WO2011066990A2 and WO2011066991A2 disclose a kind of method of utilizing the micro-anti-mirror structural simulation curved surface in surface, by inclination angle and the position angle of accurate each micro-anti-mirror of control, on micro-anti-mirror, deposit light and become coating structure, can realize the effect of OVMI, it is advantageous that the angle information that can control arbitrarily each pixel, realize the accurate control to image information and details.
It is a kind of light change technology having with angle variable color that liquid crystal light becomes.Utilizing cholesteric liquid crystal material to have with angle variable color and unique polarization properties exploitation the anti-fake mark that masses can recognition feature combination with hidden information characteristics is one of developing direction of current Techniques of Optical Security.At the nineties initial stage, Reveo company first applied for liquid crystal material as variable color and patent US5599412 that polarization pigment is used.Rolic company has made this type of Security element by cholesteryl liquid crystal in conjunction with directed imaging technique (LPP/LCP), this Security element is had with angle and change and also to possess polarization hidden image feature when presenting different colours.
Zero order light become (zero order light change diffraction image) be by the employing cycle the optical grating construction between 200-400nm and on optical grating construction landfill high-index material form.Because cycle of optical grating construction is less than visible wavelength, institute thinks sub-wave length grating, therefore can only reproduce zero order light.The main color of zero level light variation image reproduced image when self rotation with in surface obviously changes, and change color is specific, describable, and playback light is polarized light.
It is the optical anti-counterfeit element of interfering based on Bragg that co-extrusion light becomes film, and this optical anti-counterfeit element adopts the Bragg interference effect between the multilayer film that refractive index is different to form the change color feature changing with angle.
With glazing, become technology and adopt optical anti-counterfeit element that these light change technology form due to the defect of they self technical characterstic, component structure, manufacture craft, make that the color that they can form is partially dark, anti-counterfeiting characteristic is single, design space is narrow, thereby limited its anti-counterfeit capability.
Summary of the invention
The change color feature that the present invention is directed to existing Techniques of Optical Security is simple, design space is narrow, anti-counterfeiting characteristic is single, need specific complicated technology and equipment to form the complicated defects such as effect, and a kind of anti-fake product that can overcome the optical anti-counterfeit element of above-mentioned defect and adopt this optical anti-counterfeit element is provided.
The invention provides a kind of optical anti-counterfeit element, this optical anti-counterfeit element comprises base material, surface relief structure layer and color functional layer, described base material comprises first surface and the second surface of mutual opposition, described surface relief structure layer can be modulated to incident light and from the direction of the light of described color functional layer, wherein, one of following situation that is arranged as of described base material, surface relief structure layer and color functional layer:
