PROBLEM TO BE SOLVED: To provide a high-quality heat-sensitive recording material which is almost free from a texture fog and shows outstanding color development properties and shelf stability. SOLUTION: The heat-sensitive recording material has a heat-sensitive color developing layer containing a normally colorless or a pale-color color developing chemical compound, a developing chemical compound which thermally develops a color in the color developing chemical compound and a sensitizer as main components, formed on a support. The developing chemical compound is shown in formula (1) (wherein, n is 2 to 10). The sensitize is a dibenzoylmethane. |
