Description
Technical field
The present invention relates to a kind of anti-fake material and preparation method thereof, especially relate to a kind of manufacture method of magnetic anti-counterfeit minitype particle.
Background technology
The application of anti-counterfeiting technology in industry-by-industry can help consumer to differentiate rapidly the true and false of commodity, and Protection of consumer rights and interests help enterprise customer to hit fake products, stop to prevent in batches making, protecting brand names, maintaining enterprise image simultaneously, avoid economic loss.Conventionally the anti-counterfeiting technology of using at packaging field mainly adopts as follows: accurate printing, laser hologram printing, metal wire, fluorescent dye, magnetic dyestuff, heat sensitive dye, micro printing, punching block die mould etc.These technology were all once brought into play certain effect at the use initial stage, but with low content of technology by these anti-counterfeiting technology ubiquities, the textural association defect such as be easily decrypted.As method for anti-counterfeit such as traditional fluorescence, magnetic, temperature-sensitives, be exactly the privileged site at product, with ink special, stamp specific graphical symbol, then by special means, go to detect.Along with progress and the popularization of technology, these methods are easy to counterfeiting person and decode and utilize.The advantage of technical formula and equipment will not exist, and adulterator just can a large amount of anti-the making in unbridled ground after having grasped this technology and equipment.
Along with expanding economy, forge and false proof between contradiction more and more sharp-pointed.Especially along with the popularizing of computer graphics disposal technology, color photocopying, high precision scanning, high resolution printed, number printing technology and large-sized print equipment, make the false proof measure of micro of former reliable typography acquisition be easy to be imitated.Therefore, research and develop various novel, efficient microstructure anti-counterfeiting technologies, be one in the urgent need to work.
Chinese patent CN2192930 discloses a kind of grain type supper-reduce antiforge anti-counterfeiting mark and with the product of anti-counterfeiting mark, it is the fine process that adopts integrated circuit, on silicon or other material, print out the specified special graph reference lamina of user, Pasting be embedded in product or the packing of product on as anti-false sign.The meticulous micron order that reaches of figure, extremely difficult imitated.Can in different levels, be observed by naked eyes, common magnifier or microscope, be easy to identification.This shrink technology comparatively speaking production cost is high, is also difficult to form large-scale production, only has specific user to accept.
The disclosed utility model patent of Chinese patent CN201754317U relates to a kind of nanometer particle anti-counterfeiting mark, comprise matrix, on matrix, be printed with Information Level, it is characterized in that being also printed with on Information Level the nano particle false proof layer of layer of transparent, in nano particle false proof layer, scatter a plurality of nanometer false proof particles.This utility model has solved prior art anti-counterfeiting mark self easily by counterfeit defect, have advantages of be difficult for by counterfeit, long service life, antifalse effect good.Equally, because this technology is that form with label exists, therefore on use field, also there is very large limitation.
