Abstract (en)
A heat-sensitive recording medium comprises, on a support, a heat-sensitive recording layer comprising a leuco compound and an organic acid capable of coloring upon contact with the leuco compound, wherein the back of the support is coated with an agent for lowering the electric resistance which comprises a guanidine salt or guanidine derivative salt singly or in combination with cationic polymer having a quaternary ammonium group. The heat-sensitive recording medium has a low electric resistance and therefore, it is free from troubles in feeding or discharging thereof from the recording machine and also from impairment of the thermal head.
