摘要： The ink to be impregnated into the figure portion 6 of the processed stamp plate 10 in the stamp device 11 is formed of polyoxyethylene-alkyl-phenyl ether and oil soluble dye melted therein and regulated to have the viscosity in a range of 300 - 2000 cps, more preferably, 500 - 1500 cps. This stamp device 11 can thus extremely improve all of stamping characteristics, i.e., stamping durability, ink spreading condition, ink seeping condition, ink permeation speed, and the number of trial stamping times.

摘要： A method for stabilizing a microporous marking structure (38) is disclosed. The method comprises the steps of placing a microporous marking structure (38) in conjunction with an absorbent material (42) within a stabilizing device (10). A positive pressure is then applied to the microporous marking structure (38) within the stabilizing device (10) until a sufficient amount of ink originally retained within the microporous marking structure (38) is forced to flow therefrom into the absorbent material (42) so that the microporous marking structure (38) obtains a substantially stabilized state.

摘要： [Object] To provide a stamp capable of preventing penetration of an ink into an impression member from starting even when an unexpected external force is applied to a frame or a case.
[Solving Means] A stamp unit (10) comprises a case (16) that accommodates an ink occluding member (15) and a frame (13) on which an impression member (12) formed of a porous film is tightly stretched, and a leaf spring (20) is provided between the case (16) and the frame (13). By an elastic repulsive force of the leaf spring (20), the impression member (12) and the ink occluding member (15) are constantly separated from each other, and the ink is not allowed to penetrate the impression member (12) during distribution. In this way, even when an unexpected external force is applied to an unprocessed stamp unit (10), the impression member (12) and the ink occluding member (15) do not come into contact with each other, and penetration of ink into the impression member (12) is prevented from starting.

摘要： The invention provides an ink composition for a reversibly thermochromic stamp, a stamp image of which does not decolor even when the same is left to stand in a high temperature environment, and a stamp containing the same.
[Solution]
An ink composition for a reversibly thermochromic stamp including a reversibly thermochromic microencapsulated pigment encapsulating a reversibly thermochromic composition including:
Component (A): an electron-donating color-developing organic compound,
Component (B): an electron-accepting compound, and
Component (C): a reaction medium causing reversibly an electron transfer reaction between the Component (A) and the Component (B) in a specific temperature range, water and a thickener,
wherein:
the reversibly thermochromic composition exhibits a 1st hue at a temperature t 1 , and exhibits a 2nd hue at a temperature t 4 higher than the temperature t 1 , and coloring can be altered reciprocally between the 1st hue and the 2nd hue by changing the temperature;
the reversibly thermochromic composition exhibiting the 1st hue at the temperature t 1 starts color change at a temperature t 3 , when the temperature is elevated, and exhibits completely the 2nd hue in a temperature range not lower than the temperature t 4 higher than the temperature t 3 ,
the reversibly thermochromic composition exhibiting the 2nd hue at the temperature t 4 starts color change at a temperature t 2 , when the composition is cooled, and exhibits completely the 1st hue in a temperature range not higher than the temperature t 1 lower than the temperature t 2 ,
a hysteresis property to keep the 1st hue or the 2nd hue in a temperature range between the temperature t 2 and the temperature t 3 is indicated, and
the temperature t 2 is a temperature not higher than 15°C, and the temperature t 4 is a temperature not lower than 80°C.
