| abstract | PROBLEM TO BE SOLVED: To provide a stamp containing a reversibly thermochromic stamp ink composition capable of easily discoloring (erasing) an imprint image by frictional heat generated by friction. SOLUTION: A seal material 2 having continuous pores is impregnated with an ink containing a reversible thermochromic microcapsule pigment, and the pigment exhibits tautomerism between a first hue and a second hue with respect to a color density-temperature curve. began to discolor and temperature in the first color reaches a temperature t 3 in the process of rising, become completely second color at higher temperatures t 4 above temperature range than the temperature t 3, in the second color state in the process of temperature decreases, when the reached temperature t 2 less than the temperature t 3, the second color begins to discolor, become completely the first color at a lower temperature t 1 the following temperature range than the temperature t 2, the temperature A stamp 1 exhibiting a hysteresis characteristic in which the first hue or the second hue is maintained in a temperature range between t 2 and temperature t 3 , the temperature t 4 being a temperature of 50 to 95 ° C., and including the friction member 4.
