Description of the invention: [Technical field to which the invention pertains] Shuming is an anti-counterfeit label, in particular, an anti-counterfeit label and a method for identifying the same. μ [Prior Art] In order to resist counterfeiting, protect genuine products, and protect the interests of consumers and the interests of the direct traders, anti-counterfeiting technologies and mechanisms for assisting in identifying authenticity have become more and more important. Among them, the anti-counterfeit label with special design is the anti-counterfeiting measure of the current market. However, to achieve an effective anti-counterfeiting effect, anti-counterfeiting: weaving through the two features of the high-tech door sand technology that is easy to identify and difficult to imitate. At present, most of the anti-counterfeit labels on the market usually need to use additional detection equipment to identify the authenticity. Only a few kinds of detection equipment can identify the authenticity, such as: laser full-image standard iron, etc. Such a standard iron has the disadvantage of being easily copied because the technical door is not high. For example, the anti-counterfeiting technology described in the Taiwan Patent Publication No. 1317321 patent mainly uses a precision electroforming mold forming method to form a pattern layer composed of microscopic holes on the surface of a finished body, since the pattern layer is mainly ray diffraction. The unique visual perception produced is a feature of the prevention, so the diameter of the micro-cavities must be designed to be close to the wavelength of the light wave, and the county is set to be less than 1 _' but the precision required by this technology is extreme. 'With the high processing cost, and the lack of continuous mass production, the lack of 0 Taiwan Patent Publication No. 2 _, the anti-counterfeiting technology 201225026 described in the patent case is the application of the original laser for metal processing Paper film processing and the formation of a micron diameter of 〇〇5 coffee ~ 〇15 by the field shot can not be directly used to identify the identification effect using auxiliary tools, but because the use of door rate laser, can not be used in high In terms of molecular materials, the technology T can be implemented on paper-based articles such as securities, and there is a lack of application. In addition, the 'Taiwan Patent Publication No. 20G935373 patent discloses a technique for forming a micro-grained sheet of a micro-scale or micron-sized identification pattern' and further making the micro-engraved sheet into an anti-counterfeit label. In the identification, it is necessary to use auxiliary tools such as large mirrors or microscopes to determine the authenticity, but it has the disadvantages of being difficult to identify. In summary, although several kinds of anti-counterfeit label making techniques have been developed, various anti-counterfeiting technologies still exist. The space for improvement is not painted, and the anti-counterfeiting effect is obtained for I. There is still a need for continuous development of an anti-counterfeit label which is easy to identify and difficult to counterfeit and a manufacturing technique thereof. [Invention] Therefore, the object of the present invention is Is to provide an easily identifiable anti-counterfeit standard iron which is not easy to be counterfeited without the aid of instrumentation and high manufacturing technology. Thus, the easily identifiable anti-counterfeit label of the present invention comprises a layer substrate and a layer combination An identification film layer formed on the substrate layer and made of a light-transmitting polymer material. The identification film layer includes one and a lower surface The lower surface, the surface of the micro-scale hole which is recessed downward on the surface of the upper surface, and the surface of the s-substrate layer are spaced apart from each other, and a predetermined 201225026 map is distinguished from the upper surface of the surface. And a background area surrounding the predetermined pattern area, wherein the micron-sized holes are formed in one of the predetermined pattern area and the background area. The beneficial effect of the identifiable anti-counterfeit label of the invention is that: The polymer material is made into the film layer, and a micron-sized hole having a pore diameter of only micro-unsized is formed thereon, and the characteristics of light diffraction can be utilized, as long as the liquid is used to define the pattern formed by the holes and the like. Presenting or contrasting with the visual effect produced by the semi-transparent pattern originally defined by the micron-sized holes, and can be used as a basis for anti-counterfeiting judgment, so that the anti-counterfeit label of the invention is easy to identify and difficult to counterfeit and relatively straightforward: : The pseudo-effects can be directly recognized when the product is applied to a high-priced product, and the value of the product is false, and the value of the product is not true. The anti-counterfeit standard is used to identify the anti-counterfeit standard. The identification method of the anti-counterfeit standard is included in the following steps: and the identification = the first item in the 4 patent range The anti-label is, and the pore size of the micron-sized holes on the 5 / θ is 2_~3〇μηι; a liquid is applied to the film layer to make the micro-holes filled with the liquid Full, the temple micro-level hole, after the presentation..., know the film layer before the application of the liquid, ^ visual effect for anti-counterfeiting identification. The invention of anti-counterfeiting identification of each ancient soil & 2 polymer material / into the 1 have ' "The effect is that as long as the high-micron-sized holes are provided in the predetermined area of the film, the μ-woven fabric is placed on the thin layer of the 201225026 film which is applied to the anti-counterfeit mark, and the liquid can be optically diffracted. The characteristics of the micro-scale holes are defined by the contrasting visual effect before and after the application of the liquid. Since the special instrument is not required, the anti-counterfeit identification can be performed by using the easily obtained liquid. The invention has practical effects that are easy to implement. The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to Figures 1 and 2, a preferred embodiment of the identifiable security label 2 of the present invention can be attached to a product to identify the authenticity of the product. The security label 2 includes a layer substrate layer 3, and an identification film layer 4 which is bonded to the substrate layer 3 and made of a light-transmitting polymer material. Wherein the identification film layer 4 is preferably made of a light-transmitting polymer enamel material. In this embodiment, the substrate layer 3 and the identification film layer 4 are bonded by an adhesive layer 5, but the identification film layer* should not be limited by this: the bonding mode of the substrate is, for example, the identification The film layer 4 can also be bonded to the substrate layer 3 by printing, lamination or coating, and the film layer 4 can be subjected to predetermined processing. - The identification film layer 4 includes a lower surface S 41 joined to the substrate layer 3 by the adhesive layer 5, an upper surface 42' opposite to the lower surface 41, and a plurality of spaced apart The micro-scale hole 43' recessed downwardly from the upper surface 42 distinguishes between the predetermined pattern area 421 and the background area 422 surrounding the predetermined pattern area 421, and the micro-scale holes are shaped as 201225026. Within the predetermined pattern area 421. In the present embodiment, although the micro-scale holes 43 are formed in the predetermined pattern region 421 as an example, the arrangement positions of the micro-scale holes 43 should not be limited, and the micro-scale holes can also be made. 43 is set in the background area 422, and the predetermined effect can still be achieved. The pattern of the predetermined pattern area 421 is not limited, and can be designed into symbols, characters, trademarks or various shapes according to the product or actual needs. In the present embodiment, the character "P" is used as the pattern of the predetermined pattern area 421. In addition, the material of the identification film layer 4 should not be limited as long as it is a light-transmissive polymer material, whether transparent or translucent, and is polymerized by a polymer selected from the group below. Made of materials: polyethylene (referred to as PE), polypropylene (four) state (four) coffee referred to as PP), polyethylene terephthalate terephthalate, referred to as PET), polycarbonate (p〇 Iycarb_e, abbreviated as PC) and oriented polypropylene (oriented p〇lypf0pyiene, abbreviated as (10)). The identification film layer 4 is made of the above-mentioned material, so that the identification film layer 4 has the characteristics of being light-transmissive, easy to process, and low in raw material cost, and the micro-scale holes 43 form an optical diffraction effect. The predetermined pattern area 421 is rendered translucent to provide an effect that can be visually recognized. Among them, the thickness of the identification thin county 4 is preferably such that if the thickness is lower than 3μηι', since the thickness of the thin gauge is difficult to manufacture, it is easy to purchase the raw material, and if the thickness is higher than the Qing, it is difficult to display the security. *I Relatively - providing more energy when the thicker film forms the micron-sized holes 43 can also result in higher equipment costs. 201225026 θ is matched with the material of the identification film layer 4. The micron-sized holes 43 are preferably formed in the identification hole by laser processing and the method of laser filming. Among them, laser processing is used. When the micron-sized holes 43 are processed, the high-power laser is processed on the polymer material, which is easy to produce and stagnate, and the aperture of the micro-scale holes 43 cannot be made very small, and if the holes 43 are too large, The optical diffraction effect is deteriorated, resulting in insufficient anti-counterfeiting capability. In the present embodiment, the neutron-level holes 43 are formed by using a UV laser having a power of 7 W. In actual production, the same can be used. Identifying the polymer material of the thin layer 4 to adjust the power value of the laser processing: to produce a micro-scale hole 43 conforming to specifications and quality requirements. Since laser processing and micro-electromechanical processing are both prior art, no further description is provided herein. In addition, the micron-sized holes 43 may be a blind hole type as shown in FIG. 2, extending from the upper surface 42 of the identification film layer 4 to a predetermined depth that does not penetrate the lower surface 41. And preferably, The micron-sized holes are conical-slotted holes having a tapered aperture, and each has a large aperture portion 431 formed on the upper surface 42 and a small aperture portion 432 adjacent to the lower surface 41, and a connection is large The reduced diameter section 433 between the aperture portion 43 1 and the small aperture portion 432. In addition, as shown in FIG. 3, the micron-sized holes 43 may extend downward from the upper surface 42 to extend through the lower surface. 41 is a perforated pattern and is also a tapered cylindrical hole pattern designed to have a tapered aperture, and each has a large aperture portion 431 formed on the upper surface 42, a small aperture portion 432 formed in the lower surface 41, and a reduced diameter section 433 connected between the large aperture portion 431 and the small aperture portion 432. The perforation or blind hole can make the 201225026 predetermined figure (4) 421 have a translucent visual effect and can be matched with a liquid. forms a contrast.

If the pore diameter is smaller than ¥, it is necessary to adopt a more complicated processing equipment and process, and it is not easy to continuously mass-produce. As a result, the processing cost is too high and it is not economical. If the aperture is larger than 30μιη, the optical diffraction effect will be poor. In the subsequent anti-counterfeiting identification, the contrast visual effect is not obvious enough. In addition, the distribution pattern of the micron-sized holes U in a predetermined region (here, the predetermined figure (4) 421) is not limited, and a predetermined visual effect can be obtained by random or fixed sorting, and a preferred distribution density thereof is obtained. It is set at 2〇, _ / / 2, _ "2, if the «level hole 43 is lower than 2 〇 '〇〇〇 / cm2 ', because the spacing between the micro-scale holes 43 is too large 'also causes The optical diffraction effect is not &, and then the anti-counterfeiting material is subsequently processed, resulting in insufficient contrast visual filaments (4), which increases the difficulty of identification. If the micro-scale holes 43 are higher than (10) and the surface is w, the micro-scale holes 43 If the density is too high, it will interfere with each other, so that the image medium +, the current gentleman, the pattern or the text presented by the predetermined pattern area 421 is distorted, and cannot be used for anti-counterfeiting identification. Referring to FIG. 1 and FIG. 4, the anti-counterfeiting identification of the present invention The preferred embodiment of the method is mainly carried out in conjunction with the anti-counterfeiting label 2, and comprises the following steps: ^The anti-counterfeit label 2 as described above, the structural features of the anti-counterfeiting label 2, and the identification of the identification ^ & 3 thick film layer 4 design and limitations, and The description is the same and will not be repeated here. Step 2 is to apply a liquid ι〇 to the identification film layer 4 so that the 201225026 micron-sized holes 43 are filled by the liquid 10, and by "(4) (4) The contrast visual effect presented before and after the application of the liquid 进行 is used for anti-counterfeiting identification. Wherein, when the liquid 10 used in the field is a colored ink as shown in FIG. 4, after the liquid level 填 fills the micron-sized holes 43, the micro-scale holes 43 are distributed in the identification film layer 4. The predetermined pattern area 421 is in a state in which the transparent state becomes apparent. Here, a text "ρ" having a predetermined color is developed, whereby the predetermined pattern area 421 can be utilized by the half before and after the application of the liquid 1 The transparency becomes a clearly visible contrast visual effect, and the presented content is judged to be true with the security label 2: When the anti-counterfeiting test is carried out with colored ink, the anti-counterfeiting standard is measured... The re-opening is the original translucent state, so this type of method is only used once a month, which is called a sub-destructive anti-counterfeiting label. Body 2! When the liquid used in the liquid is a transparent solvent, after the liquid is completely filled with the micron-sized holes 43, since the micropores are filled with the solvent, the Π尧 作用 effect disappears, and the visually sees the The film layer 4' is identified, and the character "Ρ: disappears in the predetermined pattern area 421 in a semi-transparent state, and after the dried liquid 10 is dried, the original text disappears because the optical:= It will show up again. Thereby, the J can also use the predetermined pattern area 421 to change from the translucent state to the disappearing state after applying the liquid body dry wine, and then change the contrast visual effect of the internal phase state, and the predetermined figure (4)- The authenticity of the product combined with the anti-counterfeit iron 2 is transparently produced.

Next, the films a1, bl, el, and dl are respectively bonded to the sticker to form the anti-counterfeit labels al', bl, cl', and dl'. As shown in Fig. 7, when observed by a microscope, the pore size of the micron-sized pores can be measured as 1 〇μιη. • Referring to Figure 6, it can be seen that when the density of the micron-sized holes is 2〇, 〇〇〇/cm2, although the character “ρ” can still be recognized, the text “ρ” is dim and part of it The peripheral lines are relatively fuzzy and faded. When the density of the micron-sized holes is 1,0〇〇, 〇〇〇/cm2, although the character “ρ” can be recognized, the holes are dense and the light is high. Interference, causing the text "ρ" to be too bright', and the surrounding lines are smudged, making the text "ρ" less contrasting with the background of 201225026, when the density of the micron holes is 5〇,〇〇 When 〇/cm2 and 100,000/cm2, the visual effect of the peripheral lines is clear and the contrast with the background is very obvious. Therefore, in order to carry out the anti-counterfeiting=, it is easier to perceive the change of the visual effect. The density of the holes should not be too high or too low, and is preferably limited to 2 〇, 〇〇〇 / cm 2 〜 1 〇〇, 〇〇〇 / cm 2 . The above films a, bl, and cl are respectively pasted on a blue sticker to form a blue security label a 1", b 1", c 1, and then coated with a transparent solvent (in the second, using water).祙 Make the micron-sized pores filled with transparent solvent. Refer to Figure 8 'where (A), (8), and (C) respectively indicate the label ai", bl, ', c1m before applying the transparent solvent, after applying the transparent solvent, and the transparent solvent. The state after drying up, as shown in Fig. 8, can be seen that the anti-counterfeit labels al,, M,,, cl, and the text Γρ" appear in the disappearing state after (B) the transparent solvent is applied, and after the water is dried, The text "p" defined by the micron-sized holes shown in (C) of Fig. 8 will appear again. The above films a, bl, and cl are respectively pasted on a white sticker to form a white anti-counterfeit label, al, ,, bl, ", cl, ", and then coated with blue ink to make the micron-sized holes Fill the ink, see Figure 9, (A), (B) respectively indicate the label al ",, Μ, ", cl, " before the application of blue ink, and the state after the application of blue ink' 9 It can be seen that the text "p" on the security label al"', bl"', cl'', and (B) after the blue ink is applied, a text "P" with a distinct color appears. Specific Example 2: Using the micro-electromechanical process technology, the predetermined pattern on four transparent permeable pET polymer films with dimensions of 2cm (length) x 2cm (12 201225026 wide) χ 25μιη (thickness) The pattern of the part mark "forms a micron-sized hole in the predetermined pattern area in which the fixed knife cloth is not smashed into the film", and the films are numbered b3, c3, Μ, μ, respectively, wherein the holes of b3 and c3 are respectively The pore size is unloaded, the pore depth is 20μιη, the pore diameter of b4 and c4 is 1〇μηι, the pore depth is 2〇^m, and the distribution density of the pores on b3 and b4 is 5〇, 〇〇〇/cm2 Before, the distribution density of holes in c3 and c4 is 1〇〇, 〇〇〇/cm2, see Figure 1〇, respectively for the visual effects of b3, C3 'b4 'c4 film test pieces, which can be seen. The blind hole type (non-penetrating film) hole for the claws can exhibit an image of a translucent state under the above-mentioned distribution density condition, and the peripheral line of the presented image is clearly distinguishable, according to which, if The distribution of micron holes is limited to 20,000/cm2~i〇〇, within a range of /cm2 Such holes can be defined in micron-out image clarity of presentation. The films b3, c3, b4, and c4 can also be respectively bonded to the sticker to form an anti-counterfeit label. If the anti-counterfeit standard iron made of the films b3, c3, Μ, Μ is tested with the colored ink as shown in the specific example 1, the same contrast effect as in the specific example 1 can be exhibited. When a blind hole type hole is formed on the film, a contrasting visual effect can be produced before and after the application of the liquid, so that it is also suitable for providing an anti-counterfeiting identification function on a specific product. In summary, the identifiable anti-counterfeit label 2 and the identification method thereof of the present invention can achieve the following functions and advantages, so that the object of the present invention can be achieved: The present invention uses the light-transmitting polymer film to set the micron-scale The substrate of the hole 43 does not require complicated processing procedures, and the micro-sized hole 43 can be formed on the film directly by the low 13 201225026 power laser processing or microelectromechanical technology to form the identification film layer 4, since The apertures of the holes 43 are controlled to a micron level to increase the difficulty of counterfeiting. The micron-sized holes are extremely small, but the layout of the distribution area can still be combined to define a pattern or text visible to the naked eye. Cooperating with the light-receiving characteristics of the identification film layer 4 and the optical diffraction phenomenon generated by the material hole 43 enables the film layer 4 to produce a distinct contrast visual effect before and after being applied by the liquid 1Q as a basis for anti-counterfeiting identification, and There is no need to use a specific auxiliary instrument. As long as the liquid can be obtained by hand (4), the result is recognized. Therefore, the present invention is easy to identify and difficult to imitate. The practical characteristics, and to be kept very suitable 咼 5 Wo of monovalent products combined to provide an effective security identification results. The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention. All remain within the scope of the invention patent.
