Preferably, this visible information printing layer is such that when there is another layer below it that expresses specific information in cooperation with the information printing layer, the information supporting function of the other layer is completely impaired. In order to prevent this, it is preferable to leave a part of the entire surface of the brittle film layer. Also, under the visible information printing layer, for the purpose of making the visible information easier to see, a visible information printing layer is provided. A colored printed layer having a hue different from the hue may be further provided, and this colored printed layer is also printed leaving a part of the entire surface of the brittle film layer, as in the case of the above-mentioned visible information printed layer. In addition to this, it is preferable to

一つを発揮させることができるからである。The ultraviolet coloring agent to be contained in the other layer, preferably the adhesive layer, is not particularly limited, and generally includes fluorescent pigments such as fluorescent whitening agents. Examples of fluorescent brighteners include oxazole-based, coumarin-based, naphthalimide-based, triazonyl-based, and pyrazoline-based brighteners; specific examples include 2,5-bis[5°-t-butylbenzoxazolyl (
2)] Thiophene, 5,6-dimethyl-4'-carbomethoxystilbenzoxazole, etc., and the product names are Uvitex 0B-P (manufactured by Ciba Geigy),
Examples include Kayalite O3 (manufactured by Nippon Kayaku).The amount of these fluorescent brighteners to be used is not particularly limited as long as the color development can be discerned, but it is usually
．． It is preferable to contain 1 to 5% by weight, and as the ultraviolet coloring agent, it is preferable to use an ultraviolet coloring agent that migrates to the surface or surface layer of the adherend when the adhesive layer is attached to the adherend. By including a UV coloring agent that easily moves, such as the above-mentioned Ubitenx 01P [manufactured by Ciba Geigy] in the adhesive layer, even if the fragile label is peeled off, the fragile label will remain affixed. This is because the location can be recognized by irradiating light containing a large amount of ultraviolet rays, and one of the effective anti-theft mechanisms can be exerted in fragile anti-theft labels and the like.

ようにも構成できる。As described above, when the brittle label of the present invention is used in cooperation with the information printing layer and other layers to express specific information that cannot be clearly identified under normal light, but can be clearly identified under light containing a large amount of ultraviolet rays. Although described in detail, the fragile label of the present invention can also be configured so that the information printing layer alone expresses such specific information.
情報印刷層単独で通常光の下では明確に識別できないが
紫外線を多く含む光により明確に識別できる特定の情報
を表現するには、例えば、前述のように他層と共働させ
て情報印刷層により特定の情報を表現させる場合とは逆
に、情報印刷層に、紫外線を多く含む光により発色する
機能を有する前記紫外線着色剤を含有させれば良い。In order to express specific information that cannot be clearly identified under normal light by the information printing layer alone, but can be clearly identified by light containing a large amount of ultraviolet light, for example, the information printing layer may be used in conjunction with other layers as described above. Contrary to the case where specific information is expressed by the information printing layer, the information printing layer may contain the above-mentioned ultraviolet coloring agent which has the function of developing color with light containing a large amount of ultraviolet rays.
尚、このように情報印刷層単独で特定の情報を表現する
ように構成した場合においても、上述の場合と同様に印
刷層を複数層で構成できることは云う迄もなく、又、情
報印刷層以外の印刷層や粘着剤層に前記紫外線吸収剤を
含有させることができることは云う迄もない。It should be noted that even in the case where the information printing layer alone is configured to express specific information in this way, it goes without saying that the printing layer can be composed of multiple layers as in the case described above. It goes without saying that the above-mentioned ultraviolet absorber can be contained in the printing layer or the adhesive layer.
本発明の脆質ラベルにおいて、上記透明乃至半透明脆質
フィルム層は、印刷層の支持固定層として働く。更に、
その脆く、裂けやすいという特性により、脆質ラベルが
一旦被着体に貼付されと、貼付された脆質ラベルを、本

ため、脆質ラベルに移転防止の機能を持たすことが可能
となる。In the brittle label of the present invention, the transparent or translucent brittle film layer serves as a supporting and fixing layer for the printing layer. Furthermore,
Due to its brittle and easy-to-tear characteristics, once a brittle label is attached to an adherend, it is impossible to remove the attached brittle label while retaining its original shape. It becomes possible to provide the label with a transfer prevention function.
上記印刷層は、単独で又は他層と共働して種々の情報を

が可能となる。The printing layer, alone or in conjunction with other layers, serves to impart various information to the fragile label. Special information printing that contains information that cannot be clearly identified under normal light as one of the printing layers, but can be clearly identified under ultraviolet-rich light, either alone or in conjunction with other layers. By providing the layer, it becomes possible to provide a counterfeit prevention effect to the fragile label.

着色剤をこの粘着層に含有させることにより、脆質ラベ
ルに盗龍防止の機佳を持たすことが可能となる。The above-mentioned adhesive layer acts as an adhesive to easily attach the fragile label to the adherend, but in some cases, it may contain a coloring agent that has the function of developing color when exposed to light containing a large amount of ultraviolet rays and is easily movable. By including it in this adhesive layer, it becomes possible to provide the brittle label with the ability to prevent theft.
以下、図面を参照して、本発明の脆質ラベルの一実施例
