[Industrial Field of Application] The present invention relates to a temperature-indicating label suitable for being attached to the surface of an electrical component such as a transistor, integrated circuit, or capacitor to detect heat generation in the electrical component. [Prior Art] Temperature-indicating labels have been known in which a temperature-indicating element made by applying a composition that melts at a specific temperature to colored absorbent paper is encapsulated in a synthetic resin film, and is used for mechanical equipment, electrical equipment, etc. It is used for temperature control. As shown in FIG. 5 (front view), the temperature label 1 has a coating layer 2 of a meltable composition that is visible from the outside at room temperature, and when it reaches the melting temperature, it melts and is absorbed by the colored absorbent paper, changing its color. It looks like this and detects temperature. Although it is irreversible, the color change temperature is stable and is not affected by heating time or pressure. Also, since the temperature indicating element is encapsulated in a synthetic resin film, it has good durability. A pressure-sensitive adhesive is used to encapsulate the temperature-indicating element in a synthetic resin film, but the meltable composition changes in quality when it comes into contact with the pressure-sensitive adhesive. Therefore, the conventional temperature label 1 is
-A sectional view). That is, a temperature-indicating element cut out in a predetermined round shape (see FIG. 5) from a colored absorbent paper 3 coated with the meltable composition 2 is pasted on a synthetic resin film 6 coated with a pressure-sensitive adhesive 5. A synthetic resin film 7 with a transparent surface is attached from above. Therefore, the meltable composition 2 and the pressure sensitive adhesive 5 do not come into contact with each other.
In the figure, reference numeral 8 indicates a pressure-sensitive adhesive for attaching the temperature-indicating label 1 to a temperature-tested body (not shown), and reference numeral 9 indicates a release paper for covering the pressure-sensitive adhesive 8. [Problems to be solved by the invention] In the conventional temperature-indicating label described above, the temperature-indicating elements made of the meltable composition 2 and the colored absorbent paper 3 must be attached one by one to the synthetic resin film 6 by hand. There was a problem that it took a lot of time to manufacture. In particular, the production of small-sized temperature-indicating labels for use on temperature-tested objects such as minute electrical components has the drawback of low productivity and high cost. The present invention aims to eliminate the drawbacks of conventional temperature-indicating labels and provide a temperature-indicating label that can be mass-produced at low cost even if it is small. [Means for solving the problems] Fig. 1 (front view) corresponding to an embodiment of the present invention;
This will be explained with reference to FIG. 2 (BB sectional view). The temperature label 10 is attached to a portion of colored absorbent paper 3, which is a base paper, by melting it at a specific temperature.
A coating layer 2 of a meltable composition which is absorbed by the substrate is applied by printing. Around the coating layer 2 of the meltable composition,
A pressure-sensitive adhesive layer 5 is printed and coated on another part of the absorbent paper with a space between it and the coating layer 2. A transparent synthetic resin film 7 is adhered to the absorbent paper 3 using a pressure-sensitive adhesive layer 5 to cover the coating layer 2 of the meltable composition. [Function] Since there is a gap between the coating layer 2 of the meltable composition and the pressure-sensitive adhesive layer 5 of the temperature indicator label 10, the meltable composition does not change in quality. When such a temperature label 10 is in contact with a body to be tested and the temperature of the body to be tested rises and reaches the melting temperature of the meltable composition, the coating of the meltable composition, which is visible from the outside at room temperature, is removed. The membrane layer 2 is melted and absorbed into the colored absorbent paper 3, and the color of the absorbent paper 3 can be observed from the outside. [Example] Hereinafter, an example of the present invention will be described in detail. As shown in FIG. 2, the temperature label 10 has a coating layer 2 of a meltable composition on the center of an absorbent paper 3 made of Japanese paper, high-quality paper, etc. colored red, black, or green. (see Figure 1). As a compound constituting the meltable composition, for example, palmitic acid can be used as polyink medium (trade name,
The mixture is kneaded with an ink binder manufactured by Mino Group Co., Ltd. and used as a printing ink, and printed on absorbent paper 3 to form a white coating layer 2. A pressure-sensitive adhesive layer 5 is printed and coated around the coating layer 2 with a gap therebetween. As the material of the pressure-sensitive adhesive layer 5, for example, SK Dyne 100, SK Dyne 200, or SK Dyne 700 (trade name, acrylic pressure-sensitive adhesive manufactured by Soken Kagaku Co., Ltd.) is used. A transparent synthetic resin film 7 is adhered to the absorbent paper 3 using the pressure-sensitive adhesive layer 5 to cover the coating layer 2 of the meltable composition. As the transparent synthetic resin film 7, for example, polyester film, polypropylene film, or polyimide film is used. Furthermore, a pressure-sensitive adhesive 8 is applied to the lower surface of the absorbent paper 3.
A release paper 9 is attached to cover it. Temperature label 10 configured as in the above embodiment
For example, when using it to detect the temperature of electrical components such as integrated circuits, remove the release paper 9 and attach the temperature label 10.
Attach it to the electrical component that is the hot body to be tested. The coating layer 2 of the meltable composition, which appears white from the outside at room temperature, melts and is absorbed by the colored absorbent paper 3 when the electrical components abnormally heat up and reach the melting temperature of the meltable composition. The color of paper 3 can be observed from the outside. In the temperature-indicating label 10 of the above example in which palmitic acid was used as a compound constituting the meltable composition, a change in color could be observed when the temperature reached 55°C. Compounds constituting the meltable composition can be selected from, for example, the compounds listed in the following table, depending on the detection temperature.

As explained above, the temperature label to which the present invention is applied has a space between the meltable composition and the pressure-sensitive adhesive, so the meltable composition does not change in quality and stable temperature measurement is possible. I can do it. Both the coating layer of the meltable composition and the pressure-sensitive adhesive layer are formed by printing on absorbent paper, making it easy to mass-produce.
Can be manufactured cheaply. In particular, it is now possible to easily manufacture even small temperature-indicating labels, which have been extremely difficult to manufacture in the past, and it has become possible to expand the use of the present invention, for example, by using it for small temperature-tested objects such as integrated circuits.
