A heat-sensitive recording material is described comprising a support having a recording layer provided thereon, said recording layer containing (1) at least one colorless or pale-colored basic dye, (2) hydroquinone monobenzyl ether, and (3) at least one compound selected from compounds represented by the formulae (I) to (IV): <IMAGE> (I) <IMAGE> (II) <IMAGE> (III) <IMAGE> (IV) wherein X and Y are each a chlorine atom, an alkyl group having 1 to 7 carbon atoms, a phenyl group or a benzyl group; m and n are each an integer of 0 to 3; and R1 and R2 are each a hydrogen atom, an alkyl group having 1 to 7 carbon atoms, a phenyl group or a benzyl group, or R1 and R2 may jointly form a cyclohexane ring. The heat-sensitive recording material is suitable for use in high-speed recording, e.g., high-speed facsimiles. |
