ABSTRACT:
In the heat-sensitive recording paper produced by coating a support such as paper or the like with a coating solution containing a normally colorless or light-colored dye precursor and a developer capable of making the precursor develop color upon heating, the abrasion of a thermal head can be decreased by adjusting the total amount of sodium and potassium ions in the coating on the heat-sensitive recording paper to 1,051 ppm or less, preferably 500 ppm or less, most preferably 400 ppm or less.
