Abstract
A heat-sensitive recording material comprising a support and a heat-sensitive recording layer provided on the support, said heat-sensitive recording layer comprising an electron-donating, colorless or pale-colored dye precursor, an electron-accepting developer which reacts with the dye precursor to form images upon heating, a binder, and a specific aromatic compound. The heat-sensitive recording material has an excellent heat responsiveness, and hence recorded images having a sufficient optical density can be printed even with low energy.
