Abstract (en)
A heat-sensitive recording sheet having a high sensitivity and an enhanced resistance to curling, comprises a substrate sheet consisting essentially of a paper sheet made from a beaten dry pulp having a freeness (CSF) of 250 ml to 550 ml, and a heat sensitive color-forming layer formed on the substrate sheet and comprising a substantially colorless dye precursor, a binder, and a color-developing agent reactive with the dye precursor upon heating to provide a colored image on the layer.
