Heat-sensitive recording material

摘要

A heat-sensitive recording material in which a heat-sensitive color-developing layer containing at least an electron-donating colorless dye, an electron-accepting compound, a sensitizer and preferably an image stabilizer is disposed on a support, the heat-sensitive color-developing layer containing (1) 4-hydroxybenzenesulfonanilide as the electron-accepting compound and (2) 2-benzyloxynaphthalene and ethylenebisstearic acid amide or methylolstearic acid amide as the sensitizer, and (3) the 2-benzyloxynaphthalene (x) to ethylenebisstearic acid amide or methylolstearic acid amide (y) mass ratio (x/y) being within 95/5 to 40/60 range.
