Description
Technical Field
The invention relates to the technical field of anti-counterfeiting, in particular to a magnetic optical anti-counterfeiting element and an anti-counterfeiting product.
Background
In order to prevent lawbreakers from forging high-security or high-added-value printed matters such as banknotes, checks, cards and packaging products by means of copying or scanning and the like, optical anti-counterfeiting and magnetic anti-counterfeiting technologies are widely applied as the explicit and implicit anti-counterfeiting characteristics.
The more the anti-counterfeiting features integrated by the anti-counterfeiting element, the finer the anti-counterfeiting process, the greater the process difficulty and the higher the anti-counterfeiting performance. Optical security features are typically used for public identification, visual to the naked eye, and magnetic security features are typically readable by means of an instrument for machine identification. Combining several optical and magnetic security features on a security element has great difficulty, sometimes causing interference with each other, affecting the best performance.
For example, patent CN100532124C filed by G & D corporation proposes a optically variable magnetic structure having an interference unit, a reflective layer and a magnetic layer, having an effect and magnetic characteristics of color changing with viewing angle. All the layers constituting the security element in this structure are produced by vacuum evaporation on a substrate, the thickness of the magnetic layer being between 10nm and 1000 nm. The part removed from the magnetic layer is larger than the part removed from the metal layer, and finally a hollowed-out area is formed, and it can be seen that the hollowed-out area is only the reflecting layer and does not contain an interference unit. The hollowed-out area is not completely transparent, the hollowed-out effect formed is a hollowed-out character effect which is nearly transparent, and the magnetic area and the hollowed-out area are not mutually interfered. Is a conventional use means of magnetism, light variation and hollowed-out characteristics, and is a simple superposition of coating structures.
In the prior art, for example, in a Indonesia 50000 shield ticket security thread, a mode of printing black characters on a light-variable film is adopted, and no hollowed characters exist. Meanwhile, the black characters are formed by coating a single layer of black ink on the front surface of the optically variable substrate, and then printing magnetic codes on the other surface of the optically variable substrate. The whole process flow is complex, and meanwhile, black characters and magnetic codes are of different-surface structures, so that great difficulty is brought to ensuring the product tolerance. The common practice of improving the tolerance is to adopt a double-layer film compounding mode, the different-surface structure can only select one surface to compound the anti-counterfeiting information, and the other surface is exposed, so that a certain currency-resistant risk is caused.
