Abstract:
1. A thermosensitive recording material comprising: a support; and a thermosensitive recording layer formed on the support, the thermosensitive recording layer containing an electron-donating colorless dye and an electron-accepting accepting compound which develops color upon a reaction with the electron-donating colorless dye, wherein the thermosensitive recording material satisfies all of the following conditions (1) to (3): (1) an image density when thermal printing is performed from a side, of the support, having the thermosensitive recording layer with printing energy of 15.2 mJ/mm (2) the thermosensitive recording material contains a sensitizer comprising at least one compound selected from the group consisting of 2-benzyloxynaphthalene, dimethylbenzyloxalate, m-terphenyl, ethyleneglycol tolyl ether, p-benzyl biphenyl, 1,2-diphenoxymethyl benzene, diphenyl sulfone and 1,2-diphenoxy ethane, and an image density after the thermosensitive recording material is brought into contact with a heat source of 70° C. for 5 seconds is 0.15 or less; (3) the electron-accepting compound is a compound represented by the following Formula (1): wherein R
