PURPOSE: A temperature sensitive discoloration auto sensor is provided to simply grasp current temperature with the color changed extent of first and second color-change units being formed with temperature sensitive discoloration pigments. CONSTITUTION: A temperature sensitive discoloration auto sensor comprises a first color change unit(100) and a second color change unit(200). The first and second color change units are formed on a surface of one among transfer paper, a fabric, a sheet, and paper or a film with temperature sensitive discoloration pigments. The first color change unit is formed into an arbitrary shape in order to change a whole color over a predetermined temperature. The second color change unit is formed in a later surface and the inside of the first color change unit. The second color change unit is successively changes the color depending on a temperature rise or the whole color over the predetermined temperature. The color change temperature of the first color change unit is 35 to 50°C and the color change temperature of the second color change unit is -10 to 50°C. |
