Fig. 1 is the sectional view for the reflection-type anti false film for illustrating one embodiment of the present of invention.
Referring to Fig.1, the reflection-type anti false film 100 of one embodiment of the present of invention includes basement membrane 110 and reflective membrane 120.InstituteReflection-type anti false film 100 is stated so that being reflected from external incident laser by the reflective membrane, the phase of reflected light becomesChange and causes to interfere.Therefore, it is possible to show special pattern with interfering.Here, special pattern can be equivalent toIdentification figure.
The basement membrane 110 can be made of polymer substance.Also, the another side of the basement membrane 110 is formed with two sides stickupBand can be configured to the basement membrane 110 are attached to specific products.
The basement membrane 110 is formed with identification pattern on one side.The identification pattern can have a variety of bigSmall and shape.For example, the shape of the identification pattern may include shape of stripes, mosaic shape, Pyramid etc..
The identification can be formed with pattern by hot pressing engineering, nano impression engineering or trans-printing engineering.
The reflective membrane 120 is formed in along the molded line of identification pattern on the basement membrane 110.Therefore, instituteIt states reflective membrane 120 and may be formed to have uniform thickness.The reflective membrane 120, which can reflect to show from the external incident light, to spread outPenetrate figure.
The reflective membrane 120 may include the reflective metallics of gold, silver, aluminium, chromium and nickel etc.The reflective membrane 120It can be with the thickness of 5nm to 500nm.
The reflective membrane 120 is made by the offset being formed on the identification pattern in the reflective membrane 120The phase of light of surface reflection change.Therefore, it is possible to show specific diffraction by interfering for the light of the reflectionFigure.The specific diffraction pattern can for example be equivalent to identification figure or Quick Response Code (QR code).
According to one embodiment of present invention, it is different from existing infiltration type anti false film, the reflection-type anti false film 100 canIt is attached to the product of the various shapes including three-dimensional bits.That is, existing infiltration type anti false film penetrates the saturating of the product by lightIt crosses light and shows identification figure, therefore be difficult to use in the case that the product is opaque anti-fake using the infiltration typeFilm.
Reverse side, the reflection-type anti false film 100 of the embodiment of the present invention have use aspects not by being attached to a variety of of productThe advantages of limitation of shape or material.
Fig. 2 is the sectional view for the reflection-type anti false film for illustrating one embodiment of the present of invention.
With reference to Fig. 2, the reflection-type anti false film 200 of one embodiment of the present of invention includes basement membrane 210, reflective membrane 220 and bluntChange film 230.The reflection-type anti false film 200 to be reflected by the reflective membrane from external incident laser, reflected lightPhase changes and causes to interfere.Therefore, it is possible to show special pattern with interfering.Here, specific patternShape can be equivalent to identification figure.
The passivating film 230 is disposed over the reflective membrane 220.Therefore, the passivating film 230 can be protected described reflectiveFilm 220 and identification pattern are in order to avoid by external impact.Also, the passivating film 230 is whole to cover the identificationWith pattern, so as to inhibit anti false film 200 to be replicated.The passivating film 230 is arranged to fill the identification patternBetween gap.
The passivating film 230 can be by polyvinyl chloride (PVC), polymethyl methacrylate (PMMA), poly terephthalic acidAny one formation in the translucent resin that glycol ester (PET), polypropylene (PT), acrylic acid and epoxy resin are constituted.
Wherein, can identification pattern described in the adjustable refractive index according to the passivating film 230 offset.That is, can rootThe size and shape of identification pattern are adjusted according to the value of the refractive index of the passivating film 230.
In the case that the one side of the passivating film 230 is contacted with reflective membrane 220 and another side exposes, the passivating film 230Another side can be flat.
