ABSTRACT A heat-sensitive recording member comprises (1) a substrate, (2) a layer,on the substrate, formed by foaming an aqueous dispersion of a self-emulsifiable resin having an I/O value of 0.6 to 1.1, and (3) a heat-sensitive coloring layer, on the foamed dispersion layer, containing an electron-donating dye and an electron-accepting compound to present a color by reacting with the dye, improved in sensitivity. |
