Description

Film of the three-dimensional floating image of vision and preparation method thereof

Technical field

The present invention relates to safety anti-fake field and field of product packaging, be specifically related to a kind of dynamic, three-dimensional film, the anti-fake certificate that both can be used for cash, securities, card, passport etc., the outer packaging that also can be used for extensive stock strengthens commodity to consumer's attractive force with its special visual effect.

Background technology

The primary action of commodity packaging is that the protection commodity are injury-free.Along with improving constantly of living standard, the packing of product also is devoted to commodity are beautified and publicize except the most basic protective effect, to improve competitive power and the class of product on market.Therefore plane decoration pattern miscellaneous has appeared in the packing of product, yet along with the development of printing technology with popularize, these simple commodity external packings can be copied easily, and counterfeit goods is more and more, and manufacturer and consumer are all caused huge loss.Therefore society's urgent need is a kind of not only attractive in appearance but also can play false proof discriminating effect, is not easy again the brand-new packing of product technology that is replicated simultaneously.

Laser hologram package anti-counterfeiting technology becomes rapidly the new lover of commodity packaging once with its gorgeous color, higher manufacturing technology threshold, and rapidly diffusion.But even to this day, the fake producer has broken through Laser Holographic Counterfeit-proof Technique in all its bearings, makes it almost completely lose anti-counterfeit capability.

The people such as Kaule have proposed a kind of safety line manufacturing technology in United States Patent (USP) 4892336, also be the basis of at present popular three-dimensional stereograph manufacturing technology, it is by the generation gorgeous 3-D view true to nature that combines with the specific printed patterns of opposite side of the cylindrical lens structure in film body one side.The people such as Drinkwater propose a kind of combined safety feature of spherical microlens and little picture and text array that utilizes in United States Patent (USP) 5712731, each lenticular aperture is that 50 to 250 microns and preferred focal length are 200 microns, the mechanism of above two kinds of technical products is more thick and heavy, can't be used for safety anti-fake and the packing of commodity.

R.A.Steenblik improves the technical disadvantages of above-mentioned patent in US Patent No. 2005180020A1, and the lenticule aperture is reduced to 50 microns once, and structural thickness is also controlled 50 microns once.Although overcome like this thickness problem, along with reducing of lens opening, its processing technology thereof difficulty also significantly increases.Simultaneously limited and current printing technology, so small micro picture and text can only pass through the ultraviolet mold pressing, the method for then filling with nano dye, the technique very complicated, cost is high and yield rate is low.
