Temperature indicating material and temperature monitoring member |
摘要 |
<p>In the present invention, a temperature indicating material is prepared by incorporating, in a rewritable base system which comprises an electron donating compound, an electron accepting compound and a reversal material and undergoes color changes with temperature and time, a thermochromism controller which changes a rate of crystal to amorphous or phase-separation to non-phase-separation rate. Upon color changes with an environmental temperature, the thermochromism controller undergoes crystallization or phase separation to have a function as a place for reaction and contributes to the color changes of the temperature indicating material. The incorporation of the thermochromism controller therefore makes it possible to impart the resulting temperature indicating material with improved sensitivity to temperature at around an environmental temperature and a high S/N ratio. <IMAGE></p> |
