PROBLEM TO BE SOLVED: To provide a heat sensitive recording body, which is excellent in color developing sensitivity, favorable in whiteness and the preservability of ground color and in which fewer lowering of a printing capability occurs even being left under high temperature and high humidity (or which is favorable in re-printability). SOLUTION: In this heat sensitive recording body, a heat sensitive color developing layer includes at least one kind of a sulfonamide phenol derivative represented by general formula (1) as an organic developer and further at least one kind of the emulsion of a saturated fatty acid mono-amide represented by general formula (2). In the formula (1), X represents a hydrogen atom, a halogen atom, an alkyl group, a hydroxyl group, an alkoxyl group or a nitro group, R1 to R5 represent a hydrogen atom, a halogen atom, an alkyl group, a cycloalkyl group, an arelkyl group, an aryl group, an alkenyl group, an alkoxy group, a cycloalkoxy group, an alkenyloxy group, a nitro group or an acyl group. In addition, R1 and R2 or R2 and R3 may form an aromatic ring. In the formula (2), R6 represents a 11-21C alkyl group. |
