PROBLEM TO BE SOLVED: To provide a heat-sensitive recording body which is excellent in preserving property of a recorded section to heat or humidity and recording sensitivity, and in addition, excellent in fogging resistance and record-running property. SOLUTION: This heat-sensitive recording body has a heat-sensitive recording layer containing a leuco dye, a developer, a sensitizer and an adhesive, on a supporting body. In such a heat-sensitive recording body, as one means to achieve such properties, at least one kind of p-toluenesulfonyl-m-aminophenol and p-toluenesulfonyl-p-aminophenol is used as the developer. Also, at least one kind of 1,2-diphenoxyethane, 1,2-di(3-methylphenoxy)ethane, 2-naphthyl benzyl ether and oxalic acid di-p-methyl benzyl ester, and also, amide stearate are used as the sensitizer. |
