Description

Reversion reflector label sheet and article with fixed return reflector label sheet

The present invention relates to a reversion reflector label sheet, such as an open type retroreflective reflector label sheet that exposes glass beads (hereinafter collectively referred to as a photorefractive body) and an article to which the reversion reflector label sheet is attached.

The retroreflective reflection system is composed of a glass bead layer of a light refraction body and a reflection layer provided thereunder, by a reflection phenomenon in which light incident on, for example, a glass bead as a reflector returns to the incident direction. The reversion reflector has a closed type in which a coating layer of a colorless transparent resin is formed on the glass beads, and an open type in which the glass beads are exposed.

Patent Document 1 discloses a technique for combining a reversion reflector and a hologram to enhance anti-counterfeiting. The reversion reflection system utilizes the nature of different tones of the reversion reflector under natural light in various directions from sunlight or illumination, and is similar to the directionality of, for example, a car lamp, and is often used for traffic signs. Or back stamps, work clothes, etc. In addition, those who have special reflections are also used for anti-counterfeiting of gold vouchers, certificates, and the like. This retroreflective reflector for anti-counterfeiting often uses a closed-type return reflector that is easy to print.

Patent Document 2 discloses a technique in which a glass bead layer or a reflective layer is easily destroyed and is not likely to be reused. In the retroreflective system, it is difficult to recover the glass bead layer or the reflective layer of the reverting reflector, and it can be used for the purpose of preventing forgery, camouflage, alteration, etc. Seal as a seal.

Patent Document 2: Japanese Patent Laid-Open Publication No. 2003-29012

When the reversion reflector shown in Patent Document 2 is peeled off and attached to a recursive reflection seal or the like of a case or the like, the glass bead layer is destroyed, so that it cannot be reused. However, when an organic solvent such as an alcohol or heating is used during the peeling, the adhesive force of the adhesive layer of the returning reflector is weak, and it can be peeled off without being damaged by the glass bead layer or the retroreflective layer, and it can be reused.

The present invention has been made in view of the above problems, and it is an object of the invention to provide a reversing reflector label sheet and an article to which the recursive reflector label sheet is fixed, for example, the reverting reflector label sheet is not detected as a reversion reflector. The collapse of the glass bead layer or the return-reflective layer or the like is determined by observing the condition of the printed layer on the surface of the reverting reflector to determine whether or not the label sheet has been re-applied. As a result, it is possible to confirm the condition of unopening or opening, and to determine whether or not it is necessary. Check whether the item is forged or camouflaged.

In order to achieve the above object, the inventors of the present invention have found through concentrating research that when the glass bead exposed surface of the reverting reflector is provided with a fragile layer formed of a substance which is easily destructive to frictional force, the easily destructible layer can be used. The invention is completed by a slight force and peeling off.

That is, the reversion reflector label sheet of the present invention includes a base material layer; a return reflection layer laminated on one surface of the base material layer and capable of returning the detection light to the same direction when the detection light is incident from a certain direction An adhesive layer laminated on the other side of the substrate layer and adhered to the article; and a fragile layer disposed on at least a portion of the surface of the returning reflective layer. The retroreflective layer includes: a light refraction layer; a holding layer that holds the photorefractive layer in a state where the surface portion is exposed; and a surface that is laminated on the opposite side of the surface portion of the photorefractive layer or laminated on the holding layer Internal reflective layer. The fragile layer is formed of a substance that is easily destructive to friction.

Specific examples of the light refraction layer are, for example, a plurality of glass beads which are partially covered and adhered to the surface of the holding layer made of a thermoplastic resin laminated on the base material layer.

According to the above configuration, the paper is peeled off by bending the paperboard without bending the reversing reflector label sheet, and the article is adhered so that the hand does not touch the easily breakable layer at all. When the return reflector label sheet is pasted as described above, the easily breakable layer formed of the material which is easily destructive to the frictional force is not damaged by the application of the force which is not normally applied.

Here, as for the article in which the reversing reflector label sheet is stuck or the article contained in the article in a state in which the fragile layer does not collapse at all, there is a misconduct to replace the dummy article.

If it is necessary to replace the item that has been pasted with the return reflector label sheet, it is necessary to peel off the return reflector label sheet from the real item and reattach it to the dummy item. In addition, in the case where the ROM or the like is housed in the container body and the cover is attached to the cover surface of the container body and the cover, the replacement reflector label piece is required to be replaced in the event of improper replacement of the ROM or the like. Stripped from real items and reattached to fake items. At this time, if an inadvertent force is applied to the reversion reflector, or the damage layer is inadvertently rubbed, the destructible layer peels off from the surface of the revertive reflection layer.

When rolling up the re-reflecting reflector label attached to the article to peel it off, a bending force is applied to the fragile layer of the reverting reflector label sheet, and since the fragile layer is formed of a substance which is easily destructive to frictional force, The fragile layer will partially collapse and peel off. In particular, when a force such as a surface of a light refraction layer of a friction reversing reflector is applied, the easily breakable layer peels off.

Therefore, in the case of a real object, in the event of suspicion of forgery, alteration, disguise, etc., by observing the condition of the vulnerable layer of the reverting reflector label attached to the article, the unopened or opened condition can be confirmed. It is possible to detect whether it is forged or disguised from the collapse or fall-off state of the breakable layer. When the breakable layer does not collapse at all, it can be proved that the return reflector label sheet is not rolled up, that is, the return reflector label sheet is not reattached. Moreover, even if only a few collapses occur in the fragile layer, it can be proved that the return reflector label sheet is rolled up, that is, the return reflector label sheet is re-attached. Therefore, it is possible to check whether or not the reversing reflector label sheet of the present invention exerts a force on the presence or absence of the breakable layer on the surface of the label sheet, and whether or not a deliberate operation is applied to the article.

According to the above configuration, it is not possible to detect the collapse of the glass bead layer or the reflective layer of the return reflector label sheet, but to observe the condition of the fragile layer on the surface of the return reflector, and it is possible to confirm the unopened or opened condition. Check whether it is forged or disguised.

In the above-described reconstituted reflector label sheet, the fragile layer is preferably transparent under natural light. When the reflective layer is colored, it is preferably formed of a transparent material having difficulty in distinguishing with the color. If such a configuration is formed, even if the improper behavior of the article to which the reverting reflector label sheet has been attached is changed, since the breakable layer is not recognized, when the reverting reflector label sheet is peeled off, the surface of the sheet is easily broken by the nail or the fingertip. There are more opportunities. Since the force is applied to the surface of the sheet by the nail or the fingertip, the destruction of the breakable layer is more remarkable than the case where the returning reflector label sheet is rolled up without contacting the breakable layer. Therefore, the collapse or detachment of the easily breakable layer becomes remarkable, and it can be more clearly confirmed that the reset reflector label sheet has been reattached.

In order to study the presence or absence of the fragile layer on the surface of the label sheet, strong light (for example, light that passes through the optical lens or directionality is irradiated) is irradiated to the return reflector label sheet. In this way, in the portion of the photorefractive layer that is not covered by the easily destructible layer, the light incident on the photorefractive layer is refracted and returned, so that the color of the reversing reflective layer is emphasized, and it can be seen under natural light. More vivid colors. Further, when the breakable layer is present, the light that is refracted in the light refraction layer and reflected by the reflective layer returns is deflected by the breakable layer. Therefore, a contrast is made between the area where the fragile layer exists and the area where the fragile layer is not present. Thus, the re-reflecting reflector is irradiated with strong light to check the presence or absence of the destructible layer, and based on the result, it can be judged whether or not the re-use behavior is performed.

Therefore, according to the present invention, the detection light is emitted by the reader that emits the detection light, and the image is displayed by the image of the transparent substance, or is compared with the pattern previously stored in the reader, so that it is not used. If it is determined whether or not the inspection method for the collapse of the breakable layer occurs, the presence or absence of the breakable layer on the surface of the label sheet is detected by a simpler inspection.

It is preferable that the return reflector label sheet having the above configuration has a peeling and collapse layer which remains on at least a part of the article due to peeling from the state of adhering to the article between the base material layer and the adhesive layer. If such a configuration is formed and an attempt is made to replace the improper behavior of the article to which the return reflector label sheet is attached, the peeling and collapse layer will peel off and collapse when the reverting reflector label sheet is peeled off, and the return reflector label sheet cannot be recovered, and the weight is restored. The retroreflective reflector label attached is visually unsmooth and becomes uneven. In particular, by the presence of the retroreflective layer, the label sheet becomes hard and a stronger force must be applied for stripping. Therefore, the peeling collapse layer is also easily peeled off and collapsed. That is, the unopened or unopened confirmation can be easily understood by visually detecting the smoothness of the return reflector label sheet in addition to the detection of the breakable layer. Further, since the structure of the collapsed collapse layer is formed, the total thickness of the label sheets becomes large, so that it is difficult to bend and it is difficult to easily peel off. Therefore, in order to peel off the return reflector label sheet, it is necessary to apply a larger force, which acts on the fragile layer, and the breakable layer will surely collapse and fall off. Therefore, the effect of anti-counterfeiting and camouflage is high.

In the above-described reconstituted reflector label sheet, the reflective layer preferably has a structural color by interference of light. The so-called structural color interferes with the light reflected on the film in the wavelength range of light, and interferes with the light reflected below, and produces a color of various colors depending on the angle of observation. In order to form a reflective layer that produces a structural color, for example, (1) a single layer of a film in which a metal compound is thin to a wavelength range of light (390 nm to 770 nm); (2) a film in which a metal compound is thin to a wavelength range of light is formed into a plurality of layers; 3) Light interference and scattering occur in fine grooves, protrusions, and fine particles. If this structure is formed, the background color becomes camouflage, and the easy-to-destroy layer is difficult to see, and it is more difficult for the improper performer who wants to replace the item to which the re-reflective reflector label is pasted to be aware of the existence of the destructible layer. Therefore, the effect of anti-counterfeiting and camouflage is high.

The return reflector label sheet of the above configuration is preferably provided with a cut mark on the side of the return reflection layer. When this structure is formed, when the return-reflector label sheet remains on the release paper sheet, and the remaining portion of the label sheet is peeled off from the release paper sheet, the force applied to the return-reflection label sheet is dispersed, and further, from the cut-promoting adhesive The drying of the solvent causes the sealing tape to strongly adhere to the release sheet, so that it can be prevented from being pulled up together. Moreover, if the reflex reflector label attached to the article is peeled off if it is to be improperly actuated, it is cut from the cut and transferred to the peeling collapse layer and becomes unrecoverable, so that the resurfacing reflector label can not be wounded without injury. Sticking, anti-counterfeiting, camouflage effect is high.

The return reflector label sheet of the above-described structure is preferably formed by forming a background design having a pattern design or a character on the surface of any one of the base layers. If such a structure is formed, the reversion reflector label sheet can see the background material under natural light, so it is difficult to know the existence of the surface destructible layer, and therefore, the probability of collapse of the fragile surface of the friction surface is increased when the improper behavior is desired. High, anti-counterfeiting, camouflage effect is high.

According to the present invention, it is possible to provide a reversion reflector label sheet which does not detect collapse of, for example, a glass bead layer or a reflective layer as a reversion reflector, but observes the condition of the printing layer applied to the surface of the reverting reflector. You can determine whether the label is reposted. As a result, it is possible to confirm the condition of unopening or opening, and it is possible to determine whether or not it is necessary to inspect the article for forgery or camouflage, and to provide an article to which the returning reflector label sheet is fixed. Moreover, according to the present invention, it is difficult to produce a counterfeit of the return reflector label sheet, which has an effect on anti-counterfeiting and camouflage.

Hereinafter, embodiments of the reversion reflector label sheet of the present invention will be described in detail with reference to the drawings.

(First embodiment)

As shown in Fig. 1, the replica reflector label sheet 1 of the first embodiment includes a base material layer 10, and the retroreflective reflection layer 20 is laminated on one surface of the base material layer 10 and the detection light is incident from a certain direction. And returning the detecting light to the reflector in the same direction; the adhesive layer 30 laminated on the other side of the substrate layer 10 and adhered to the article; the easily destructible layer 40 disposed on at least a portion of the surface of the returning reflective layer 20; The surface of the base material layer 10 on the side of the adhesive layer 30 is formed by a background material 50 formed by printing a pattern design or a character. In this embodiment, the background material 50 is seen from the front side of the return reflector label sheet 1. That is, the retroreflective layer 20, the fragile layer 40, and the substrate layer 10 are formed transparently. Further, the background material 50 may be provided on the surface of the base layer 10 on the side of the returning reflection layer 20. When originality is given to the return reflector label sheet 1, it is preferable to use a specific design or trademark, a company-specific label, or the like in the background material 50.

The base material layer 10 supports a layer of the complex reflection layer 20, and a film of a polyester resin, a polyolefin resin, a cellulose resin, or an acrylic resin can be used.

The retroreflective layer 20 is composed of a light refraction layer 21, a holding layer 22 that holds the photorefractive layer in a state where the surface portion is exposed, and a layer opposite to the surface portion of the photorefractive layer 21. The reflective layer 23 on the surface.

In this embodiment, the light refraction layer 21 is made of glass beads. The glass beads 21 are embedded so that a part of the surface of the holding layer 22 is exposed. In this embodiment, the reflective layer 23 is a colorless or colored transparent. The glass beads 21 are used to refract the incident light, and the lower half is buried in the state of the holding layer 22, and the other upper half is exposed to the air. The material of the glass beads 21 is not particularly limited, and BaO-SiO ₂ -TiO ₂ -based glass or BaO-ZnO-TiO ₂ -based glass can be used. The refractive index may be any range of 1.9 to 2.2 which can be generally used. In the present embodiment, the refractive index of the glass beads 21 is about 1.9. The particle diameter of the glass beads 21 is preferably from 38 μm to 50 μm or from 45 μm to 90 μm. The glass beads 21 are preferably covered with each other in a state of being aligned with each other, but the glass beads 21 may be slightly separated. In order to impart originality to the reflector label sheet 1, the glass beads 21 may be removed in a circular or heart-shaped shape at a constant pitch.

The holding layer 22 holds the glass beads 21 and then holds the layers of the substrate layer 10 and the glass beads 21. The holding layer 22 is preferably a resin which is excellent in adhesion to the glass beads 21 and has high transparency, and is, for example, a polystyrene resin, a polyester resin, an acrylic resin, a polyoxyn resin, a fluororesin, or a polyamine. A thermoplastic resin such as a resin, a polyvinyl alcohol resin, a polyurethane resin, a polyolefin resin, a polycarbonate resin, or a polyfluorene resin.

The reflective layer 23 is provided along the lower surface side of the glass beads 21, that is, on the opposite side of the exposed surface of the glass beads 21, and is a layer that reflects light incident on the glass beads 21. The reflective layer 23 is a colorless or colored film. Here, it is possible to use a natural light irradiation to generate a structural color by utilizing the interference of light. When originality is imparted to the reflector label sheet 1, it can also be achieved by making the structural color of the reflective layer 23 original. As the reflective layer 23, a metal compound such as titanium oxide, cerium oxide, zirconium oxide, cerium oxide, zinc oxide, zinc sulfide, or the like may be used, and aluminum may be used.

The reflective layer 23 which produces a structural color can be produced, for example, by laminating a metal compound having a high visible light refractive index and a low compound as described below.

[Metal compound with high refractive index]

Zinc sulfide (ZnS): 2.40

Titanium oxide (TiO ₂ ): 2.71 (rutile structure), 2.52 (anatase structure)

Indium oxide (In ₂ O, In ₂ O ₃ ): 2.00

Tin oxide (SnO, SnO ₂ ): 1.90

Zirconia (ZrO ₂ ): 2.40

Aluminum oxide (Al ₂ O ₃ ): 1.76

Magnesium oxide (MgO): 1.74

[Metal compound with low refractive index]

Calcium fluoride (CaF ₂ ): 1.44

Magnesium fluoride (MgF ₂ ): 1.38

Sodium fluoride (NaF): 1.29

Cerium oxide (SiO ₂ ): 1.46

The layer thickness of the reflective layer 23 is preferably such that the light reflected on the surface above the film interferes with the light reflected on the lower surface, and the multilayer is preferably selected from 300 to 600 nm. If the total layer thickness of the multilayer is thinner than 300 nm, the interference light will be extinct, and if it is thicker than 600 nm, the desired structural color or appearance color turbidity cannot be obtained. The thickness of one layer is preferably in the range of 100 to 200 nm. Also, it is preferable to give a gradient among the ranges of one layer thickness. In order to exhibit a structural color in a single layer, it is only necessary to form a film of the above metal compound. In the case of a single layer, the film thickness is preferably in the range of 100 to 600 nm as long as a gradient is imparted within the range of the layer thickness.

The adhesive layer 30 is preferably formed using an adhesive having high transparency. For example, a polyester-based adhesive, an acrylic adhesive, a urethane-based adhesive, or an oxyethylene-based adhesive can be mentioned. Further, a release sheet (not shown) which is peeled off before use and exposes the adhesive layer 30 can be attached to the lower surface of the adhesive layer 30.

The fragile layer 40 is formed of a substance that is easily destructive to frictional force. The thickness of the substance is preferably from 0.5 to less than 5 μm, more preferably in the range of from 1 to 3 μm. An ink can be used for the destructible layer 40 composed of a substance which is easily destructive to friction. It is preferred that the composition of the ink, for example, only use a dye as a colorant. For example, an aqueous ink containing a water-soluble polymer or an emulsion resin can be used as the binder resin. As the water-soluble polymer, for example, polyvinyl alcohol, polyethylene oxygen, sodium polyacrylate, and the emulsion resin may be a vinyl acetate emulsion, an ethylene vinyl acetate emulsion, an acrylic emulsion, an acrylic styrene emulsion, or a vinylidene chloride emulsion. The ink may be, for example, an ink which is written on a board with a signature pen and which is easily peeled off after being dried. The breakable layer 40 can be carried out by various printing methods. In this embodiment, the destructible layer 40 is formed of a transparent material having a color which is difficult to distinguish with the color when it is transparent under natural light or colored in a reflective layer.

The background material 50 is formed by having a pattern design or a character on either surface of the base material layer 10 when the return reflection layer is transparent. Under natural light, because the background material 50 is a readable composition, a design that makes the vulnerable layer 40 less visible can be used, or a token or trademark of a proof can be used. If the re-reflecting reflector label sheet 1 is irradiated with strong light, the transparent reversion reflecting layer 20 is totally reflected by the complex reflection function, and at this time, the background material 50 is difficult to be seen. Therefore, when a part of the reflective layer 23 of the return reflection layer 20 is previously removed in such a manner that a small design in which glass beads are not provided exists, the background material 50 can be seen from the missing portion of the total reflection, and can be utilized as a hidden advertisement or Mark for other purposes.

According to the above configuration, the easily breakable layer 40 does not collapse if the damage-prone layer formed by the formation of the ink which is easily destructive to the frictional force is not applied. Peeling is performed by bending and peeling the paperboard without bending the returning reflector label sheet, and adhering to the article in such a manner that the layer is not strongly rubbed and easily broken. In order to replace the improper behavior of the article with the reverting reflector label sheet, the reverting reflector label sheet is peeled off from the real object and reattached to the dummy article, and the peeling layer is peeled off when peeling off. Therefore, by observing the condition of the destructible layer, it is possible to confirm the condition of unopening or opening, thereby detecting whether or not forgery or camouflage is performed.

The return reflector label sheet 1 according to the first embodiment is configured to pass through the fragile layer 40, the retroreflective layer 20, and the base layer 10 under natural light, and the background material 50 can be seen. The reflective layer 23 is formed in an opaque configuration, in which case the background material 50 is not provided. Further, although the breakable layer 40 is formed of a transparent ink, it may be formed of an opaque ink. In this case, it is preferable to color the reflective layer 23, and it is preferable to form the fragile layer 40 with a transparent ink having a color which is not easily distinguished from the coloring.

(Second embodiment)

As shown in FIG. 2, the reversing reflector label sheet 1A of the second embodiment includes the base material layer 10 and the transparent reflecting layer 20 laminated on one surface of the base material layer 10. And detecting that the detection light is incident on the opposite direction when incident on a certain direction; the other side of the substrate layer 10 is adhered to the adhesive layer 30 of the article; and is disposed on one surface of the surface of the return reflection layer 20A. The portion of the easily breakable layer 40; and the surface of the base layer 10 on the side of the adhesive layer 30 have background information 50 composed of a pattern design, a character, or the like.

The retroreflective layer 20 is composed of a light refraction layer 21 covered with glass beads, a holding layer 22 that holds the photorefractive layer 21 in a state where the surface portion thereof is exposed, and a layer of the photorefractive layer 21 A surface on the opposite side of the surface portion or a reflective layer 23A laminated on the inside of the holding layer 32. The destructible layer 40 is formed by forming an ink which is easily destructive to frictional force, is transparent under natural light, or is formed of a transparent substance having a color which is not easily distinguishable from the coloring when the reflective layer is colored.

In the return reflector label sheet 1A, the reflective layer 23A is different from the first embodiment. The reflective layer 23A is disposed at a focus position of the glass beads 21, and the focus position is determined by the refractive index of the glass beads 21. In the present embodiment, since the refractive index of the glass beads 21 is about 2.2, the reflective layer 23A is buried in the holding layer 22 away from the glass beads 21.

Other configurations are the same as in the first embodiment, and the same reference numerals are given to the corresponding components, and the description thereof is omitted. The action and effect are also the same as in the first embodiment.

The retroreflective layer 20 has the same configuration as that of the first embodiment, and is composed of a light refraction layer 21 covered with glass beads and a holding layer 22 for holding the photorefractive layer 21 in a state where the surface portion is exposed; A surface on the opposite side of the surface portion of the light refraction layer 21 or a reflection layer 23 laminated on the inside of the holding layer 32.

This returning reflector label sheet 1B is different from the first embodiment in that it has a peeling and collapse layer 60. The peeling and collapse layer 60 is formed by laminating a plurality of thin film films with a weak adhesive force, and when a shearing force from the lateral direction is applied, a layer which is peeled off by the interface and dissociates between the layers is likely to occur. Here, the portion where the interlayer film is dissociated is present in a portion other than the periphery of the label sheet.

Other configurations are the same as in the first embodiment, and the same reference numerals are given to the corresponding components, and the description thereof is omitted. The action and effect are also the same as in the first embodiment.

The peeling and collapsed layer 60 is a layer in which the returning reflector label sheet 1B is peeled off from the state of being adhered to an article (not shown), and is peeled off and remains in at least a part of the article (not shown).

According to this configuration, when it is desired to perform an improper behavior such as replacement of the reattachment reflector label sheet article, the return reflector label sheet cannot be recovered at the time of peeling off the return reflector label sheet. When the re-sticking is performed, not only the breakable layer 40 collapses and falls off, but also the surface of the reversing reflector label sheet 1B is uneven and can be clearly observed. Therefore, it is confirmed that the fragile layer 40 and the peeling and collapse layer 60 are observed. The condition of opening or opening, thereby detecting whether or not forgery or camouflage is performed.

(Fourth embodiment)

As shown in Fig. 4, the reversing reflector label sheet 1C of the fourth embodiment includes the base material layer 10 and the transparent reflecting layer 20 laminated on one surface of the base material layer 10. And detecting that the detection light is incident on the opposite direction when the light is incident from a certain direction; the other layer of the substrate layer 10 is adhered to the adhesive layer 30 of the article; and the substrate layer 10 and the adhesive layer 30 are formed. a peeling-disintegrating layer 60; a breakable layer 40 provided on a portion of the surface of the return-reflective layer 20; and a background material composed of a pattern design or a character on the surface of the adhesive layer 30 side of the base material layer 50 .

The retroreflective layer 20 is configured similarly to the second embodiment, and is composed of a light refraction layer 21 covered with glass beads and a holding layer 22 in which the photorefractive layer 21 is held in a state where the surface portion is exposed; The reflective layer 23A is laminated on the surface portion of the base material layer 10.

This returning reflector label sheet 1C differs from the second embodiment in that it has the peeling and collapse layer 60. Other configurations are the same as in the second embodiment, and the same reference numerals are given to the corresponding components, and the description thereof is omitted. The action and effect are also the same as in the third embodiment.

(5th to 8th embodiments)

The fifth to eighth embodiments are shown in Figs. 5 to 8. The point of the return reflector label sheet 1D of the fifth embodiment shown in Fig. 5 is different from that of the first embodiment in the point of the light refraction layer 21D of the return reflection layer 20D. The point of the return reflector label sheet 1E of the sixth embodiment shown in Fig. 6 in terms of the light refraction layer 21E of the return reflection layer 20E is different from that of the second embodiment. The reflex reflector label sheet 1F of the seventh embodiment shown in Fig. 7 differs from the third embodiment in the point of the photorefractive layer 21F of the return reflection layer 20F. The point of the retroreflective reflector label sheet 1G of the eighth embodiment shown in Fig. 8 which is the photorefractive layer 21G of the return reflection layer 20G is different from that of the fourth embodiment.

These light refraction layer layers 21D to 21G are not glass beads, but are formed optical bodies in which convex spherical surfaces are arranged on both sides, and substantially the same function as the return reflection layer in which the glass beads are arranged in a row. The other configurations are the same as the corresponding embodiments, and the same reference numerals will be given thereto, and the description thereof will be omitted.

The complex reflection layer having each of the easily destructible layers having different thicknesses was punched out into a circle having a diameter of 1 cm, and adhered to the case as a returning reflector label piece. The text "Sample" of the return reflector label is hard to see under natural light, but after the glare is illuminated, the text "Sample" will float and be seen. Then, the seal was peeled off from the case, and attached to the case again, and the strong light was irradiated to observe the seal. In the case of a seal having a fragile layer having a thickness of 3 μm, the text of "Sample" is deleted, and in the area where the characters are erased, the text of "Sample" can be seen to float in a state in which it can hardly be read. On the other hand, in the case of a seal having a fragile layer having a thickness of 5 μm, the text of "Sample" is apparently floated and visible. This observation was repeated 20 times, and any one of them was the same result.

Example 2

On the glass beads of the returning reflector (the color is red when the light is reflected by the reflective layer), a colored transparent ink having a different color tone than that which can be seen when the light is reflected by the reflective layer is used (made by Toyo Ink Co., Ltd.). FD Calton ACE mat OP nis + Suzuki Chemical microlis blue (3% relative to the total amount)) printed text "Sample".

The returning reflector having the obtained colored fragile layer was punched out into a circle having a diameter of 1 cm, and adhered to the case as a returning reflector label sheet.

The peeling test of the seal was carried out in the same manner as in Example 1. The situation in which the text of "Sample" is removed is slightly identifiable under natural light, but after the glare is illuminated, the color of the reflective layer is emphasized, and the text of "Sample" is clearly confirmed to collapse. This observation was repeated 20 times, and any one of them was the same result.

Example 3

The surface of the returning reflector (the so-called structural color in which the hue can be seen when the light is reflected by the reflective layer changes to the observation angle to form an iridescent color) (the exposed surface of the glass bead) is printed by a letterpress printing with a warm colored colored transparent ink. A thickness of 3 μm forms a fragile layer of the character "Sample".

The reversion reflector having the fragile layer was punched out into a circle having a diameter of 1 cm, and adhered to the case as a reversion reflector label piece. The text "Sample" of this returning reflector is slightly identifiable under natural light. After the glare is irradiated, the character "Sample" cannot be confirmed when the structural color of the reflective layer of the returning reflector is a warm color, but it can be confirmed when the reflected reflector is tilted and the reflective layer has a hue other than the warm color. Then, the sealing peeling test is performed, and when the strong light is irradiated and the sealing is observed, in the region where the character of "Sample" is removed, the structural color of the reflective layer is in a state other than the warm color, and the character collapses. see. This observation was repeated 20 times, and any one of them was the same result.

Example 4

On the glass beads of the reversion reflector of Example 3, a warm colored tinted transparent ink (FD Calton ACE mat OP nis manufactured by Toyo Ink Co., Ltd. + microlis red (produced at 3% of the total amount) was used to print a star of 3 μm thickness. Marking, the text "Sample" was printed in a thickness of 3 μm using the clear ink used in Example 1.

The returned reflector having the obtained two types of printing was punched out into a circle having a diameter of 1 cm, and adhered to the case as a returning reflector label piece. This return reflector label sheet only sees the star mark under natural light. Then, a peeling test of the seal was performed.

When the strong light is irradiated and the seal is observed, the structural color is emphasized, and in the area where the character of "Sample" is deleted, the text of "Sample" can be seen to float in a collapsed state that can hardly be read. Further, when the structural color of the reflective layer is a color tone other than the warm color system, the star mark floats and is visible in a collapsed state. Moreover, this observation was repeated 20 times, and all of them were the same result.

Next, a method of manufacturing the reversion reflector label sheet of the present invention will be briefly described. Here, a reset reflector label sheet having a fragile layer on a glass bead will be described.

The manufacturing step of the return reflector label sheet basically consists of the following steps: a fixing step of the glass beads, a step of forming the reflective layer, a step of adhering the substrate layer, and a film peeling step. The specific manufacturing method will be described below.

(1) Manufacture of a recursive reflector label sheet in which the reflective layer is a single layer

A polyethylene resin is applied onto a film such as a PET film, and glass beads are dispersed in a row and dried. Thereby, the lower hemisphere of the glass beads is buried in the polyethylene resin (the step of fixing the glass beads). Then, a film of a metal compound (step of forming a reflective layer) is vapor-deposited on the surface of the exposed glass beads in the range of 100 to 600 nm. Then, a polyethylene resin is applied onto the base material layer of the pressure-sensitive adhesive layer on the release sheet to serve as a holding layer, and the holding layer is bonded to the reflection layer (substrate layer adhesion step). Finally, a film such as a PET film and a polyethylene resin are peeled off (film peeling step).

Since the surface of the glass bead has irregularities, the thickness of the metal compound film changes to impart a gradient.

(2) The reflective layer is a multi-layered return reflector label sheet

A polyethylene resin is coated on a film such as a PET film, and glass beads are spread thereon to be dried, and the lower hemisphere of the glass beads is buried in the polyethylene resin (the step of fixing the glass beads). Then, a plurality of metal compound thin films (in the range of 100 to 200 nm) are deposited on the exposed glass beads to form a multilayer reflective layer (step of forming a reflective layer). Then, a polyethylene resin is applied onto the base material layer of the release sheet in the pressure-sensitive adhesive layer as a holding layer, and the holding layer is bonded to the reflection layer (substrate layer adhesion step). Finally, a film such as a PET film and a polyethylene resin are peeled off (film peeling step).

When a label sheet having a specific shape (for example, a circular shape) is formed on the obtained returning reflector label sheet having a breakable layer on the obtained glass beads, only the circular label sheet 1 becomes a sheet which is arranged on the peeling sheet 80 (refer to Figure 12). The replica reflector label sheet 1 in which only the label sheet remains on the release sheet 80 can be obtained by forming the slit 81 of the label sheet shape on the glass beads 21 and peeling only the circular label sheet remaining portion 93.

However, when the label sheet remaining portion 93 is peeled off (the sealing sheet is pulled up), the label sheet remaining portion 93 is peeled off together with the label sheet 1 (hereinafter referred to as "pulling together"). In order to prevent pulling up together, as shown in Fig. 12, a slit 81 spanning to the remaining portion 93 of the label sheet is provided on the side of the label sheet 1. The cuts 81 are provided on the periphery of the label sheet 1 so as to be diagonal to each other. This incision 81 is a half cut from the surface of the return reflector label sheet to the return reflection layer 20.

By having the slits 92 spanning the returning reflector label sheet 1 and the label sheet remaining portion 93, the drying of the solvent contained in the adhesive can be promoted from the slit, and the label sheet remaining portion 93 can be applied from the peeling cardboard 80. The force of the returning reflector label sheet 1 is dispersed, and since the returning reflector label sheet 1 is strongly adhered to the peeling cardboard 80, it can be prevented from being pulled up together. Further, the incision 81 has easy tearability for the reattachment of the reversing reflector label sheet 1, and has no recovery for reattachment, so it has a result of opening confirmation.

For the formation of the slit 91 and the label punching cut 92, the teeth of the return reflector label sheet 1 are punched, and for example, a Thomson blade or a rotary blade can be used.

Next, an article to be fixed by any of the above-described first to ninth return reflector label sheets will be described.

The article to which the return reflector label sheet is fixed may be, for example, an anti-counterfeit article or a storage article in which the anti-counterfeit article is stored. For example, in a game machine such as a Pachinko machine or a pachinsuro, the probability of releasing the beads is written in a PROM or the like, and the PROM or the like is housed in the case and cannot be easily touched. In order to prevent the replacement of the PROM and improve the probability of releasing the bead probability, a reset reflector label sheet is provided in the case of the PROM or the like, or a box containing the PROM, and it is possible to determine whether or not it is necessary to check whether or not the counterfeit or camouflage is performed.

When the recursive reflector label sheet is pasted on the PROM itself, it must be replaced with the PROM of the improper behavior, and the return reflector label sheet must be reattached. When attaching the return reflector label sheet to the joint surface of the box body and the cover body of the PROM, the return reflector label sheet must be peeled off, the cover body is opened, and the PROM of the improper behavior is replaced, and then the box body and the cover body are replaced. The return surface is attached to the return reflector label sheet.

If the reversion reflector label sheet of the present invention is reattached, the breakable layer may be destroyed. Further, when the peeling and collapse layer is provided, the peeling and collapse layer is also peeled and collapsed, so that it is immediately known that the peeling has been performed. Therefore, it can be confirmed that the condition of the item is changed without opening or opening.

The article to be attached to the reversing reflector label sheet may be, for example, a control board housed in a substrate cassette of a control board unit of the game machine, an electronic component such as a substrate cassette or a PROM, or a seal attached to a certificate attached to the case.

Fig. 14 shows a case 102 in which a certificate 101 for a certificate 101 is attached, wherein the certificate 101 is attached to a case 101 in which a control part to be replaced by a misbehavior is stored. Regarding the closure 102, a return reflector label sheet 102 is used. Further, as shown in the example, the background material 50 of the returning reflector label sheet 102 is used as a proof, and the sealing 102 can also be sealed.

Fig. 15 shows a state in which the cover member 106 is attached as a returning reflector label sheet in such a manner as to cover the joint surface of the cartridge body 104 and the cover 105 of the control member in which the object is replaced by the improper behavior.

Fig. 16 shows that the first returning reflector label sheet 110 is adhered to the control board 109 such as the CPU 107 or the ROM 108 having the object of improper behavior replacement, the control board 109 is placed on the lower casing 111, and the second return reflection is placed on the side surface. The upper casing 113 of the body label piece 112 is further connected to the lower casing 111 and the upper casing 113 by bolts. In this example, the second return reflector label sheet 112 will be positioned between the side of the lower casing 111 and the side of the upper casing 113 in the combined state. Further, in this example, the first returning reflector label sheet 110 may be attached to the CPU 107.

(industrial use possibility)

The reversing reflector label sheet having the destructible layer of the present invention is used as a substrate storage case for a game machine to prevent sealing of the opening, and if the opening is unsealed, the trace remains, so that it can be effectively utilized to prevent improper behavior.
