PROBLEM TO BE SOLVED: To provide a reversibility heat-sensitive recording material in which an image having clear contrast can be formed and eliminated, light resistance against outdoor light (sunlight) (color change of texture, discoloration of a printed part, and a deletion residual or the like) and heat resistance are excellent, and repeated durability is favorable.SOLUTION: A reversibility heat-sensitive recording material includes: a reversibility heat-sensitive recording layer including a dye precursor that is usually colorless or pale color, and a reversibility developer that forms relatively coloring state and decoloration state by difference of a heating temperature and/or a cooling rate after heating on a substrate; and a heat resistance improvement layer on the reversibility heat-sensitive recording layer, and the reversibility heat-sensitive recording material is characterized by including any one of a heat resistance improver shown by the following general formula (1) or (2) and a binder resin in the heat resistance improvement layer. |
