本発明によれば、ラベル材全体の偽造を防止して、セキュリティを高めることができるラベル材およびそれを用いた偽造検出システムを提供することができる。　また、写真の入れ替えを防ぎ、セキュリティを高めることができるラベル材およびそれを用いた偽造検出システムを提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, the forgery of the whole label material can be prevented and the label material which can raise security, and the forgery detection system using the same can be provided. Also, it is possible to provide a label material that can prevent the replacement of photos and enhance security and a forgery detection system using the label material.
以下、本発明を実施するための最良の形態について図面等を参照して説明する。　 The best mode for carrying out the present invention will be described below with reference to the drawings. *
（ラベル材）　本発明のラベル材は、基材シートと、基材シート上に設けられた粘着剤層とを備えるラベル材であって、基材シートは透明フィルムであり、粘着剤層は、粘着剤と電磁波発生体とを含有する透明な層であることを特徴とする。　なお、本発明における「透明」とは、可視光線について吸収および散乱をほとんど生じないことを意味する。具体的には、厚さ４０μｍのフィルムで可視光線について光線透過率７０％以上、より好ましくは８０％以上である。　 (Label material) The label material of this invention is a label material provided with a base material sheet and an adhesive layer provided on the base material sheet, the base material sheet is a transparent film, It is a transparent layer containing an adhesive and an electromagnetic wave generator. It should be noted that “transparent” in the present invention means that absorption and scattering of visible light hardly occur. Specifically, it is a film having a thickness of 40 μm and has a light transmittance of 70% or more, more preferably 80% or more for visible light. *
透明フィルムは、透明な樹脂フィルムであればよい。　ポリエチレンやポリプロピレン等のポリオレフィン樹脂、ポリエステル（ポリエチレンテレフタレート）樹脂、ポリカーボネート樹脂、ポリ塩化ビニルやこれを更に塩素化した塩素化ポリ塩化ビニル等の塩化ビニル系樹脂等から成るフィルム、ポリスチレン、ポリエチレンやポリプロピレン等に充填材を加えて紙のような繊維状に加工した合成紙、およびこれらの積層体や複合材などが用いられる。　その中でも、剥がそうとすると形が崩れてしまう脆質な素材であるポリスチレンが好ましい。また、貼り替え防止用カットといわれる剥がし防止のための切れ込みを入れてあるものが好ましい。透明フィルムを剥がして、写真を入れ替え、透明フィルムを元に戻す偽造が困難になるからである。　 The transparent film may be a transparent resin film. Polyolefin resin such as polyethylene and polypropylene, polyester (polyethylene terephthalate) resin, polycarbonate resin, film made of polyvinyl chloride and other chlorinated polyvinyl chloride such as chlorinated polyvinyl chloride, polystyrene, polyethylene, polypropylene, etc. Synthetic paper processed by adding a filler to a fiber like paper, and a laminate or composite material of these are used. Among them, polystyrene, which is a brittle material that loses its shape when peeled off, is preferable. Moreover, the thing which put the notch for peeling prevention called the cut for anti-replacement is preferable. This is because it becomes difficult to counterfeit the transparent film by peeling off the transparent film and replacing the photo. *
基材シートは、電磁波発生体から放出される電磁波を５％以上９５％以下透過することが好ましい。　透過率が５％以上９５％以下であれば、基材シートの厚さによって透過する電磁波の強さを容易に調整することができるからである。　また、基材シートの厚さや材質をラベルの部分ごとに変化させることで、赤外線の透過の度合いを変化させ、パターンを形成することもできる。　 The base sheet preferably transmits 5% or more and 95% or less of the electromagnetic waves emitted from the electromagnetic wave generator. This is because if the transmittance is 5% or more and 95% or less, the intensity of the electromagnetic wave that is transmitted can be easily adjusted depending on the thickness of the base sheet. Also, by changing the thickness and material of the base sheet for each portion of the label, the degree of infrared transmission can be changed to form a pattern. *
粘着剤層は、粘着剤と電磁波発生体とを含有する透明な層である。　粘着剤に特定の電磁波発生体を含有させることで、ラベル材の偽造を困難とし、かつ、短時間で見分けることができる。　粘着剤層は、粘着剤、電磁波発生体、および、電磁波発生体を粘着剤中に分散させる分散剤を含有することが好ましい。　 The pressure-sensitive adhesive layer is a transparent layer containing a pressure-sensitive adhesive and an electromagnetic wave generator. By including a specific electromagnetic wave generator in the adhesive, it is difficult to forge the label material and can be distinguished in a short time. The pressure-sensitive adhesive layer preferably contains a pressure-sensitive adhesive, an electromagnetic wave generator, and a dispersant for dispersing the electromagnetic wave generator in the pressure-sensitive adhesive. *
粘着剤層は、基材シートの全面に形成されていることが好ましい。　広い範囲から電磁波を放出することで、スキャナによる検出が容易になるからである。　 The pressure-sensitive adhesive layer is preferably formed on the entire surface of the base sheet. This is because detection by a scanner is facilitated by emitting electromagnetic waves from a wide range. *
また、粘着剤層は、パターン状に形成されていることが好ましい。　パターン状に形成された粘着剤層は、粘着剤層のみで偽造防止マークとして機能する。　パターンとしては、バーコードパターンなどを用いることができる。　さらに、基材シートの厚さや材質をラベルの部分ごとに変化させ、かつ、粘着剤層をパターン状に形成することで、基材シートと粘着剤層のパターンを組み合わせることもできる。　 Moreover, it is preferable that the adhesive layer is formed in pattern shape. The pressure-sensitive adhesive layer formed in a pattern functions as a forgery prevention mark only with the pressure-sensitive adhesive layer. * As a pattern, a barcode pattern or the like can be used. Furthermore, the pattern of the base sheet and the pressure-sensitive adhesive layer can be combined by changing the thickness and material of the base sheet for each portion of the label and forming the pressure-sensitive adhesive layer in a pattern. *
粘着剤は、特に限定されるものではなく、たとえば、エマルジョン系、ソルベント系、ホットメルト系の粘着剤が用いられる。素材は、アクリル系、ゴム系など任意である。粘着特性は被貼着物の種類に応じて選定される。例えば、一度貼着した後には剥がす必要がない場合、強粘着や、さらに粘着力が強い超強粘着や、冷凍糊と呼ばれる粘着特性が望ましい。　 The pressure-sensitive adhesive is not particularly limited, and for example, an emulsion, solvent, or hot-melt pressure-sensitive adhesive is used. The material is arbitrary such as acrylic or rubber. The adhesive property is selected according to the kind of the adherend. For example, if it is not necessary to peel it off after it has been pasted, it is desirable to have an adhesive property called strong adhesive, ultra-strong adhesive having a higher adhesive strength, or frozen paste. *
電磁波発生体とは、電磁波の発生源となりうる物体を意味する。　電磁波発生体は、電磁波など特定のエネルギーにより励起され、特定の波長の電磁波を放出する物体であることが好ましい。ありふれた物質ではないので偽造が難しくなるからである。また、電磁波で励起される場合は、励起される電磁波と放出する電磁波とで、波長が異なることが好ましい。検出が容易になるからである。　電磁波発生体が放出する電磁波は、ラジオ波、紫外線、赤外線、および、可視光線などである。例えば、赤外線発生体などを用いることができる。　電磁波発生体は無機物質であることが好ましい。無機物質よりなる電磁波発生体は、耐候性に優れ、時間の経過にあまり関係なく電磁波を発生させることができるからである。　 An electromagnetic wave generator means an object that can be a source of electromagnetic waves. The electromagnetic wave generator is preferably an object that is excited by a specific energy such as an electromagnetic wave and emits an electromagnetic wave having a specific wavelength. Because it is not a common substance, it is difficult to forge. In addition, when excited by electromagnetic waves, it is preferable that the wavelength differs between the excited electromagnetic wave and the emitted electromagnetic wave. This is because detection becomes easy. The electromagnetic waves emitted by the electromagnetic wave generator are radio waves, ultraviolet rays, infrared rays, visible rays, and the like. For example, an infrared generator can be used. The electromagnetic wave generator is preferably an inorganic substance. This is because an electromagnetic wave generator made of an inorganic substance has excellent weather resistance and can generate an electromagnetic wave regardless of the passage of time. *
