的を達成することが出来た。(Prior Art and Problems) Conventionally, thermostatic substances have been used as paints by dissolving them in solvents or dispersing them in dispersion media. However, such paints are easily affected by the external environment, have a short period of use, and are limited in the places where they can be used. In order to eliminate these drawbacks, we conducted intensive research to develop a temperature indicator material that does not limit the usage conditions, and as a result, we were able to develop a special temperature indicator material and achieve the purpose of the invention.

性能を持っている。(Means for Solving the Problems) As a result of extensive research, the present inventors have obtained a transparent solution by mixing one or more complex salts represented by the general formula (I) that exhibit a remarkable color change upon dehydration. The object of the invention could be achieved by using a temperature-indicating material coated with a substance capable of forming a film. The complex salt used in the present invention has the general formula (I) MX2(hmta)2·nH2O

There are products that change color in several stages, albeit discontinuously, as the temperature rises. That is, they have a kind of thermometer-like performance.

別な考慮は必要でなく一般公知の方法でよい。Since the discoloration is due to dehydration from the complex salt, if the film has poor air permeability, the discoloration may become unclear, or the discoloration will not occur at a certain temperature. Therefore, the film used in the present invention only needs to have heat resistance and air permeability, and for example, a cellulose ether derivative can be used. No special considerations are necessary for the coating method, and a generally known method may be used.

If the sample aqueous solution becomes highly viscous, it will be difficult to apply it to a spray drying granulator, so this point needs to be taken into consideration. The complex salt is added directly or in the form of an aqueous solution to the coating material aqueous solution, and after stirring, a homogeneous aqueous solution is obtained. Then, a coated body containing the complex salt as a core material was obtained using a spray drying granulator.

等にも利用出来る可能性がある。(Effect of the invention) When the solvent is water, there is no problem of toxicity or flammability in film formation. The complex salt, which is a thermophilic substance, releases only water when heated, so it does not deteriorate the surrounding environment. The discoloration is very obvious. It does not corrode the material whose temperature is being measured. Unlike other temperature measuring instruments, the use of cards and sheets makes it possible to measure temperature distribution on curved surfaces. Furthermore, it has a simple structure with no mechanical operating parts, and is completely unaffected by vibrations. In addition, printed temperature-indicating materials change color due to temperature changes, so they may be used for advertisements, pamphlets, and the like. Industrially, heat detection and
It may also be used medically to discover faulty circuits and to discover lesions due to temperature differences.
