Abstract

Disclosed is a transparent holographic anti-counterfeit marking material structure comprising a polyester film substrate which is provided with a disjuncting layer, a protecting layer, an information layer and a gum applying layer, wherein the information layer and the protecting layer, made of highly refractive chemical medium materials, form a transparent holographic anti-counterfeit film. When sunlight or a pointolite irradiates the holograph, the reflected holograph can be seen clearly not only from the front but also from the back. When the holograph is unsealed, the polyester film at the upper layer will separate and peel from the polyester information layer. The torn polyester film is provided with no grating and the holograph left on the marking bearer is totally or partially damaged. With simple structure, the utility mode can be widely used to guard against counterfeiting of product brand, maker, package, bills and documents as well as be used in package compounding, bronzing and transfer printing, playing the multiple functions of decoration, beautification and anti-counterfeiting.

Embodiment

Constituting of transparent holographic anti-fake marking materials structure is provided with peel ply 2, protective seam 5, Information Level 3 and gum layer 4 on mylar base material 1; Protective seam 5, Information Level 3 become the carrier of grating through the mold pressing distortion; scribble gum layer 4 at last; when hologram is taken off when opening; the mylar on upper strata will separate with protective seam 5, resin Information Level 3 and be peeled off; do not have grating on the mylar of taking off, and the hologram of staying on the stock has suffered all or part of or regular destruction.The utility model base material can also be used for thermoprint type hologram; its structure is the same substantially; different is thermoprint type the superiors mylar 1 and resin Information Level 3 be separated in thermoprint the time produce good separation property; the heat-sensitive glue that is coated in the bottom then produces very strong cohesiveness when meeting hot pressurized; the protective seam 5, the resin bed 3 that have grating like this bear tight complete being bonded on the thing, make it can't take off at all.The utility model base material 1 can be PET or polyester materials such as OPP or PVC.The utility model also can not established protective seam 5 between peel ply 2 and Information Level 3.

In the described structural sheet of the present utility model; constitute transparent holographic anti-fake film with chemical mediator material as Information Level, protective seam with high index of refraction; when sunshine or pointolite are returned by the holographic interference fringes diffraction, and though the front or the back side we can see its reflection hologram clearly.

The transparent holographic anti-fake marking materials is a base material by mylar; be coated with, coating comprises release layer, protective seam, Information Level, gum layer structure are formed (seeing Figure of description 2), can also substrate layer, peel ply, Information Level, gum layer structure form (seeing Figure of description 1).Peel ply, protective seam and Information Level are the key components of holographic anti-counterfeiting label material; in order to improve the high-diffraction efficiency of Information Level; its prescription hybridizes to inorganic material in the macromolecule chemical material, according to performance, with the accurate coating of material or evaporation on the mylar base material.

Because these inorganic material hydridization have high index of refraction to the high polymer chemistry material, the interface difference of this medium is strengthened, the light of participating in diffraction is strengthened, when sunshine or pointolite shine hologram, the high-index material prescription has strengthened the holographic interference fringes diffraction efficiency greatly, no matter it is therefore positive, we can see its reflection hologram (seeing Figure of description 3) clearly the back side, 30 is laser-light transparent anti-fake material holographic recording pattern among Fig. 3,31 is visible light, 32 is visible hologram or word, 33 is visual hologram or word, and 34 is transmitted light.

Different with aluminizer is that its diffraction light all reflects after aluminizing, and any image is can't see at the back side.Do not need the structure of aluminizing because the transparent holographic anti-fake marking materials has changed, it is excellent in important that the high index of refraction chemical materials just seems.This material can carry out precision coating or vacuum coating equipment by the electron gun sputtering method to be made and also can adopt crucible vapour deposition method evaporation (seeing Figure of description 4), and 40 be electron gun among Fig. 4, and 41 is that plated film is bulging, and 42 is vacuum chamber.The advantage of " transparent holographic anti-fake marking materials ":

1, adopts the high index of refraction chemical material, make the transparent material behind the impression all can see the hologram that diffraction is returned on positive and negative two sides.

2, the peel ply between the mylar of the information layer surface and the superiors, be coated in below the Information Level pressure sensitive adhesive with bear thing and be pasted together, when hologram is uncovered, the mylar on upper strata will produce with Information Level and peel off, make the hologram of staying on the stock produce all or part of or regular destruction, make it to copy at all.
