PROBLEM TO BE SOLVED: To provide reversible thermochromic printed matter that has unexpectedness in which a pattern is expressed by temperature change without receiving restriction of design, and a size and a shape of a pattern, and a state after color change are not expected.SOLUTION: In reversible thermochromic printed matter 1, a non-color change punctiform print image 4 and a reversible thermochromic punctiform print image are regularly arranged on a substrate 2, the reversible thermochromic punctiform print image is performed by color change by temperature change, and a pattern is configured to be visible; or in the reversible thermochromic printed matter, two or more reversible thermochromic punctiform print image in which a color change temperature or color of before and after color change is different are regularly arranged on the substrate, the reversible thermochromic punctiform print image is performed by color change by temperature change, and a pattern is configured to be visible. |
