    摘要: The present invention provides a heat-sensitive recording material comprising a substrate and a heat-sensitive recording layer provided thereon, the layer comprising a color forming system that combines an electron-donating colorless dye and an electron-accepting compound, in which the electron-accepting compound is a compound represented by the formula R1-Ph-SO2R2 (wherein R1 represents a hydroxyl group or an alkyl group, R2 represents -Ph, —NH-Ph, -Ph-OR3 or —NH—CO—NH-Ph, R3 represents an alkyl group, and Ph represents a phenyl group), and at least the heat-sensitive recording layer is formed by curtain-coating a coating solution for the heat-sensitive recording layer.
