CHARACTER/SHAPE DEVELOPMENT METHOD OF TEMPERATURE SENSING BODY

摘要

PROBLEM TO BE SOLVED: To provide a display and development method for characters or shapes of a temperature-sensitive discoloration body whose color change is discolored or whitened from a dark color when a low temperature rises to a high temperature. SOLUTION: The character or shape desired to be displayed is previously embedded by printing etc., to a base material 102 under the temperature-sensitive discoloration body 101 in the color of the temperature-sensitive discoloration body or the color different therefrom. At the low temperature, the portion of white different from the color of the temperature-sensitive discoloration body is visible through the color of the temperature-sensitive discoloration body but the same color as that cannot be recognized. When the temperature rises high, the temperature-sensitive discoloration body discolors or whitens and therefore the embedding of the white cannot be recognized but the embedding of the red becomes recognizable.
