Abstract
In a heat-sensitive recording sheet having a heat-sensitive coating layer comprising a colorless to light-colored dye precursor as color former and a color developer which causes said dye precursor to develop a color by reacting with said dye precursor when heated, the color development sensitivity of said sheet, particularly at low temperatures, is enhanced by using benzyl p-hydroxybenzoate as said color developer and allowing said heat-sensitive coating layer to further comprise a terephthalic acid ester having a melting point of 60.degree. C. or higher and a fatty acid amide or derivative thereof having a melting point of 60.degree. C. or higher.
