PROBLEM TO BE SOLVED: To provide a temperature-sensitive printed article for which even a plate type having a low masking property such as an offset printing can be used, and of which the cost is low. SOLUTION: An invariable printed section which is formed of a temperature- non-sensitive ink 2, and a variable printed section which is formed of a temperature-sensitive ink 1 so that the same color and the same density as the invariable printed section may be presented, are positioned in such a manner that the invariable printed section and the variable printed section may not be superposed, and arranged on one sheet of a paper. Thus, by forming desired information under a masked state with a temperature-non-sensitive ink printed section B and a temperature-sensitive ink printed section A, when a temperature becomes a specified value or higher, the temperature-sensitive ink printed section A decolors, and the color of the paper appears, and the specified information appears by the paper appeared section. An ink layer of the base does not need to be masked such as a conventional temperature-sensitive printed article, and therefore, a plate type is not restricted. |
