Abstract
The utility model relates to a transparent laser holographic protective card film, which is an anti-counterfeiting film. The utility model is composed of an organic film printed with a holographic pattern, an optical interference effect pattern protective layer which is formed from metal material and dielectric material with high and low refractive indexes, and a bonding layer. The utility model is stuck on the article which is prevented from counterfeiting, or the utility model wraps the article, so the surface detail of the article can be observed through the film, and the utility model which is stamped on the film of the laser holographic pattern has light interference effect. The possibility that counterfeit articles are replicated by copy or printing can be avoided. The utility model is especially suitable for the plastic package of effective special certificates and valuable papers. The utility model is favorable for identifying, guarding against, and striking all counterfeiting behavior.
Description
The utility model relates to Film Optics and the holographic technique in the optics.
The false-proof film product that adopts optical principle to make has two big classes at present: holographic optical seal product and holographic watermark product.Adopt the product of holographic optical seal fabrication techniques to form, and at organic film or be coated with on the organic film of aluminium film and make hologram pattern, during use film is attached to by top (the seeing accompanying drawing 1) of false proof thing by organic film, aluminium film and adhesive sticker.Because the aluminium film is thicker in this film morphological element, can not have the transparency,, then do not observe by the surface details of false proof thing if be attached to by on the false proof thing with it.The product of holographic watermark fabrication techniques is an interference effect of utilizing multilayer film, under different angles, can observe by false proof thing surface by multilayer dielectric film and to present different color (seeing accompanying drawing 2).Above product is used for generally requiring on the false proof thing more.In order to obtain existing false proof hologram pattern, can observe by the surface details of false proof thing by false-proof film again, the Chinese patent patent No. 9524255614 titles: " laser hologram watermark card-protecting film " disclosed being printed with and has been coated with on the organic film of hologram pattern by high (H), low (L) the index medium alternate overlapping multilayer dielectric film of forming of material (HLHL......H), can find out that by embodiment this multilayer dielectric film is at least by five layers of alternate overlapping composition of high and low dielectric material (HLHLH).It has solved existing false-proof hologram pattern, can observe by the technology of the surface details of false proof thing by false-proof film again, but because this deielectric-coating is made up of multilayered medium material, the multilayer dielectric film evaporation is on the hologram pattern film, its complex process, the process equipment costliness of requirement.
The purpose of this utility model is, in order to obtain existing laser holographic pattern, can observe by the surface details of false proof thing by the transparent counterfeiting film again, and false-proof film with optical thin film interference effect, simplify simultaneously technological process again, reduce production costs, the spy provides the holographic card-protecting film of another kind of transparent laser.
In order to realize above task, the holographic card-protecting film of the transparent laser that the utility model provides.This card-protecting film includes patterned layer, optical interference effect pattern protective seam and tack coat.Patterned layer is selected organic film material for use, and impresses required hologram pattern thereon, as anti-false sign.There are on the organic film of hologram pattern to be coated with optical interference effect pattern protective seam this protective seam one deck rete that can be thickness constitute less than the metal material of 2000 , or one deck rete (as Fig. 4 a, Fig. 4 b) that constitutes by dielectric material at impression; Or the two tunic layers (as Fig. 4 c) that constitute by metal material and dielectric material; Or by high (H), the alternate overlapping three layer dielectric HLH (as Fig. 4 d) of low (L) index medium material.And scribble tack coat (seeing accompanying drawing 3) thereon.
The holographic card-protecting film of the transparent laser that the utility model provides; splendid from seeing effect in appearance; if with its attach or plastic packaging on by false proof thing; seeing through this film not only can observe by the surface details of false proof thing and observe the laser holographic pattern sign; and on the organic film of hologram of impression, have the covering rete of interference effect and protection hologram pattern again, thereby prevented the possibility of duplicating the counterfeit product with the way of duplicating or print.It is specially adapted to the plastic packaging of effective special-purpose certificate, as resident identification card, various cards, card, the securities of the distribution of departments such as finance, the tax, public security, traffic, industry and commerce, post and telecommunications, help identification, prevent and hit all forgery and illegal imitation of brand-name products behaviors, on making, compared with the prior art simplify technology again, reduced production cost.
