About the disclosed retroeflection body of patent documentation 2, peel off and will destroy glass bead layer in case will stick on retroreflection sheet on casing etc. etc., therefore can't re-use., if use the organic solvent such as alcohol or heat when peeling off, the bonding force of the bonding coat of retroeflection body weakens, can in the situation that do not destroy glass bead layer, peel off in the reflection horizon, might re-use.
Summary of the invention
The present invention puts in view of the above problems and finds out, its purpose is to provide a kind of retroeflection body labei sheet to reach the article that fixedly are pasted with this retroeflection body labei sheet, this retroeflection body labei sheet is not that check is as the destruction such as glass bead layer, reflection horizon etc. of retroeflection body, distinguish and whether again pasted labei sheet but can be applied to printed layers situation on the retroeflection surface by observation, the situation that result can not break a seal or break a seal is confirmed, thereby can be judged to there is no need to check whether article have been carried out forgery, personation.
What the inventor etc. furtherd investigate in order to achieve the above object found that: when being provided with the destructible layer that is formed by the material that friction force is had destructible on the beaded glass exposure at the retroeflection body, very little power will make the destructible layer peel off.Thereby completed the present invention.
That is, retroeflection body labei sheet of the present invention comprises: substrate layer; Retroreflective layer, it is laminated on a face of substrate layer, and can make this detection light to the equidirectional retroeflection when detecting light from prescribed direction incident; Bonding coat, it is laminated on another face of substrate layer, and is adhered to article; And the destructible layer, it is arranged at least a portion on the surface of retroreflective layer; Retroreflective layer comprises: anaclasis body layer; Retaining layer, anaclasis body layer is remained state and the reflection horizon of the surface element exposure of this anaclasis body layer, be laminated on the face of a side opposite with surface element of anaclasis body layer or the inside of retaining layer, the destructible layer is formed by the material that friction force is had destructible.
The object lesson of anaclasis body layer is a plurality of beaded glasses, and these a plurality of beaded glasses are retained as a part and imbed the state on surface of retaining layer and the state that is paved with, and this retaining layer is laminated to substrate layer and is made of thermoplastic resin.
According to above-mentioned structure, so that the release backing paper bending does not make the mode of retroeflection body labei sheet bending peel off, and the mode that at all can not encounter the destructible layer with hand sticks on retroeflection body labei sheet on article.When so pasting retroeflection body labei sheet, only otherwise the destructible layer that is formed by the material that friction force is had destructible is applied the power that usually can not apply, the destructible layer just can not be destroyed.
At this, for the article that show no sign of destroyed state with the destructible layer and be pasted with the article of retroeflection body labei sheet or be contained in article inside, might want and forge the devious conduct that article are changed.
If change the devious conduct of the article that are pasted with retroeflection body labei sheet, retroeflection body labei sheet is peeled and it sticked on again on the forgery article from authentic articles.In addition, for holding ROM etc. and close the lid, cover at the faying face of container body and lid the article that are pasted with retroeflection body labei sheet in container body, if change the devious conduct of ROM etc., retroeflection body labei sheet is peeled and it is sticked on again from authentic articles and forge on article.At this moment, in case the retroeflection body is applied careless power, perhaps careless the wiping rubbed the destructible layer with the hands, and the destructible layer will be from the surfacial spalling of retroreflective layer.
Dig when peeling off will stick on retroeflection body labei sheet on article, the destructible layer of retroeflection body labei sheet is applied bending force, and this destructible layer forms by the material that friction force is had destructible, so this destructible layer is destroyed locally and peeled off.Particularly, when having applied the power of wiping the anaclasis body layer surface of rubbing the retroeflection body with the hands, the destructible layer will peel off.
Therefore, for authentic articles, if existentially forgeable, distort, during the suspicion of personation etc., can stick on by observation the situation of the destructible layer of the retroeflection body labei sheet on article, the situation that does not break a seal or broken a seal is confirmed, thereby can be detected whether carried out forgery, personation according to the destruction of destructible layer or the state that comes off etc.When the destructible layer shows no sign of failure, provablely do not dig retroeflection body labei sheet, namely again do not paste retroeflection body labei sheet.In addition, when the destructible layer has occured even when little by little destroying, provablely dug retroeflection body labei sheet, namely again pasted retroeflection body labei sheet.Thereby whether the destructible layer on labei sheet surface exists or its state that comes off by inquiry, is confirmed whether retroeflection body labei sheet of the present invention has been applied power, and article has been implemented the operation that makes a stab.
According to above-mentioned structure, be not the destruction of glass bead layer, reflection horizon etc. by detecting retroeflection body labei sheet, but can be applied to by observation the situation of the destructible layer on the retroeflection surface, the situation that does not break a seal or broken a seal is confirmed, can be detected thus and whether article carried out forgery, personation.
The retroeflection body labei sheet of above-mentioned structure preferably, the destructible layer is by in the situation that transparent or have and color in the reflection horizon and form the transparency material that is difficult to the color of this color discrimination and form under natural light.According to this structure, the devious conduct of the article replacing of retroeflection body labei sheet will be pasted with even want to carry out, be formed with the situation of destructible layer due to None-identified, therefore when peeling off retroeflection body labei sheet, mostly use nail and finger tip and wipe the destructible layer of rubbing the sheet surface with the hands.Owing to the sheet surface being applied the power of nail, finger tip, to compare with the situation of digging retroeflection body labei sheet with not contacting the destructible layer, the destruction of destructible layer can be obviously.Thereby, the destruction of destructible layer, come off more obviously, therefore can confirm more significantly again to paste the situation of retroeflection body labei sheet.
For whether the destructible layer of investigating the labei sheet surface exists or its state that comes off, to retroeflection body labei sheet irradiation high light, for example via the light after optical lens, light that direction is consistent.So, in the part that does not cover the destructible layer of anaclasis body layer, incide the anaclasis of this anaclasis body layer and return, so the color in reflection horizon strengthens, compare with the color of seeing under natural light, can see distincter color.On the other hand, if the destructible layer exists, the light that returns in the refraction of anaclasis body layer and in reflective layer reflects is because of the deflection of destructible layer.Therefore, in the zone that has the destructible layer with do not exist between the zone of destructible layer and can produce contrast.Like this, investigate whether there is the destructible layer to retroeflection body labei sheet irradiation high light, according to its result, can judge whether to have carried out re-using behavior.
Thereby, according to the present invention, utilize the reader of radiation detection light to scan detection light, the show transparency pattern of material or compare to identify with the pattern that is contained in advance in reader of image, thereby need not take to judge at the destructible layer whether such inspection method has occured to destroy, just can check whether the destructible layer of investigating the labei sheet surface exists or its state that comes off by more simple.
The retroeflection body labei sheet of above-mentioned structure preferably has the stripping damage layer between substrate layer and bonding coat, this stripping damage layer autoadhesion is peeled off in the state of article and can be stripped from least a portion of destroying and remaining in article.According to this structure, the devious conduct of changing at the article that will attempt to be pasted with retroeflection body labei sheet and peel moment of retroeflection body labei sheet, the stripping damage layer just is stripped from destruction, retroeflection body labei sheet can't be recovered again, and the retroeflection body labei sheet of having carried out again pasting is that a glance just can be found out and unsmooth and have a concavo-convex situation.Especially, owing to there being retroreflective layer, so the labei sheet hardening, for peel off need to be larger power.Thereby the stripping damage layer also easily is stripped from destruction.That is, the confirmation that does not break a seal or broken a seal also can easily be distinguished by the smoothness of visual inspection retroeflection body labei sheet except detecting the destructible layer.In addition, in the structure with stripping damage layer, because the gross thickness change of labei sheet is large, therefore be difficult to bending, can not peel off simply.Therefore, want to peel off retroeflection body labei sheet, need to apply larger power, when this masterpiece had been used in the destructible layer, the destructible layer is destroyed coming off reliably.Therefore, prevent that the effect of forging, palming off is higher.
The retroeflection body labei sheet of above-mentioned structure preferably, the reflection horizon produces schemochrome by the interference of light effect.Schemochrome refers to the light and the light interference of reflecting at lower surface in the upper surface reflection of the film of light wavelength degree, and produces the color of the phenomenon of various colors according to the angle of watching.Make the reflection horizon that produces schemochrome, for example can list, (1) metallic compound is made the light wavelength (single thin film of degree of 390nm～770nm), (2) metallic compound is made the multilayer film of light wavelength degree, (3) utilize fine groove, projection, particulate to make light produce interference, scattering.According to this structure, background color becomes camouflage color, is difficult to see the destructible layer, and the people who wants to carry out devious conduct that the article that are pasted with retroeflection body labei sheet are changed is difficult to notice the existence of destructible layer more.Therefore, prevent that the effect of forging, palming off is higher.
The retroeflection body labei sheet of above-mentioned structure preferably is provided with otch at the side of retroreflective layer.According to this structure, when with the mode of residual retroeflection body labei sheet on release backing paper with the labei sheet remainder when release backing paper peels, can disperse the power that retroeflection body labei sheet applies, further promoted the drying of the solvent that bonding agent is contained by otch, sheet is adhered to stripping film more firmly, therefore can prevent with rising.In addition, when the retroeflection body labei sheet that will be pasted on article in order to carry out the devious conduct wish peels, be torn from otch, propagate into the stripping damage layer and can't recover again, therefore can not again paste with no damage retroeflection body labei sheet, thereby prevent that the effect of forging, palming off is higher.
The retroeflection body labei sheet of above-mentioned structure preferably, retroreflective layer is transparent, is formed with background information on any surface of substrate layer, this background information has pattern or word.According to this structure, retroeflection body labei sheet can be seen background information under natural light, therefore be difficult to know have the destructible layer on the surface, therefore when wanting to carry out devious conduct, wipe the probability rising of rubbing lip-deep destructible layer with the hands and making its destruction, thereby prevent that the effect of forging, palming off is higher.
According to the present invention, be not check as the destruction such as glass bead layer, reflection horizon etc. of retroeflection body, distinguish and whether again pasted labei sheet but can be applied to printed layers situation on the retroeflection surface by observation.Result, can provide a kind of retroeflection body labei sheet to reach the article that fixedly are pasted with this retroeflection body labei sheet, the situation that this retroeflection body labei sheet can not break a seal or break a seal is confirmed, thereby can be judged to there is no need to check whether article have been carried out forgery, personation.In addition, according to the present invention, because be difficult to make the counterfeit of retroeflection body labei sheet, prevent the effect of forging, palming off so have.

Then, the manufacture method of simple declaration retroeflection body of the present invention labei sheet.At this, the situation of the retroeflection body labei sheet that has the destructible layer on beaded glass is described.
The manufacturing process of retroeflection body labei sheet comprises fixedly operation, the formation operation in reflection horizon, the stickup operation of substrate layer, the film stripping process of beaded glass substantially.Below, concrete manufacture method is described.
(1) reflection horizon is the manufacturing of the retroeflection body labei sheet of individual layer
Upper surface coating polyvinyl resin at films such as PET films scatters beaded glass and carries out drying to arrange shape thereon.Thus, make the lower semisphere of beaded glass bury in polyvinyl resin (the fixedly operation of beaded glass).Then, at the upper surface of the beaded glass that exposes, with the film (the formation operation in reflection horizon) of evaporation metal compound in the scope of 100～600nm.Then, apply polyvinyl resin on the substrate layer that is laminated to by bonding coat on stripping film, it is sticked on (substrate layer stickup operation) on above-mentioned reflection horizon as retaining layer and with substrate layer and this retaining layer, last, peel off film and the polyvinyl resins (film stripping process) such as PET film.
Due to the surface at beaded glass exist concavo-convex, so film thickness change of metallic compound, band has levels.
(2) reflection horizon is the retroeflection body labei sheet of multilayer
Upper surface coating polyvinyl resin at films such as PET films scatters beaded glass thereon and carries out drying, makes the lower semisphere of beaded glass bury in polyvinyl resin (the fixedly operation of beaded glass).Then, in the film (scope of 100～200nm) of a plurality of metallic compounds of upper surface evaporation of the beaded glass that exposes, the reflection horizon (the formation operation in reflection horizon) of making multilayer.Then, apply polyvinyl resin on the substrate layer that is laminated to by bonding coat on stripping film, it is sticked on (substrate layer stickup operation) on above-mentioned reflection horizon as retaining layer and with substrate layer and this retaining layer, last, peel off film and the polyvinyl resins (film stripping process) such as PET film.
When the retroeflection body labei sheet that has the destructible layer on beaded glass that will obtain make given shape, for example during circular labei sheet, making only has circular labei sheet 1 to be arranged in the thin slice (with reference to Figure 12) that forms on stripping film 80.The retroeflection body labei sheet 1 that only has labei sheet to remain in to form on stripping film 80 can be by applying the otch 91 of labei sheet shape on beaded glass 21, and only peel off circular labei sheet remainder 93 and obtain.
But, when peeling label sheet remainder 93 (removing the sheet slag), the situation that labei sheet remainder 93 and labei sheet 1 are peeled off (below be called " with rise ") together can occur.In order to prevent with rising, as shown in figure 12, at the side setting of labei sheet 1 otch 91 across labei sheet remainder 93.Otch 91 is set to periphery in labei sheet 1 each other in the diagonal angle.This otch 91 is to be applied to the hemisect of retroreflective layer 20 from the surface of retroeflection body labei sheet.
By this being set across the otch 91 of retroeflection body labei sheet 1 and labei sheet remainder 93, promoted the drying of the solvent that bonding agent is contained by otch, when release backing paper 80 peels labei sheet remainder 93, the power that is applied to retroeflection body labei sheet 1 can be disperseed, retroeflection body labei sheet 1 is adhered to release backing paper 80 securely, therefore can prevent with rising.And otch 91 has tearability with respect to the stickup again of retroeflection body labei sheet 1, does not have restoratively for again pasting, and therefore having Kaifeng and confirming effect.
About being used for applying the cutter of otch 91 and the die-cut retroeflection body of the die-cut scarfing 92 of label labei sheet 1, such as using Thomson cutter, rotating knife etc.
Then, any article that fixedly are pasted with in above-mentioned the 1st～the 9th retroeflection body labei sheet are described.
About fixedly being pasted with the article of retroeflection body labei sheet, can listing false proof article or accommodate the housing article of these false proof article.For example, in the game machines such as pinball game or Slot Machine, the probability that goes out ball is written in PROM etc., and this PROM etc. is contained in case and can't touches simply.In order to improve the devious conduct that the ball probability and to prevent changing PROM, at PROM etc. self or accommodate on the case of PROM etc. retroeflection body labei sheet is set, thereby can judge to there is no need to check whether carried out forgery, personation.
When at PROM etc. when having pasted retroeflection body labei sheet with it, need to change with wrongful PROM etc., and again paste retroeflection body labei sheet.In addition, when the mode of the mating surface of the box main body that contains PROM etc. with covering and lid has been pasted retroeflection body labei sheet, need to peel retroeflection body labei sheet, open lid and come to change with wrongful PROM etc., again paste retroeflection body labei sheet in the mode of the mating surface that covers box main body and lid.
