PURPOSE:To obtain a heat-sensitive recording sheet having an improved picture stability and a dusting preventing effect by using as a developer a combination of benzyl p-benzyloxybenzoate and benzyl p-hydroxybenzoate. CONSTITUTION:In a heat-sensitive recording sheet in which benzyl p-hydroxybenzoate is used as a developer to cause the coloration of a dye precursor when reacting with a colorless or light-color dye precursor by heating, the benzyl p-hydroxybenzoate fine particles are mixed with preferably 5-40wt% benzyl p-benzyloxybenzoate for use. EFFECT:Sensitivity of the heat-sensitive recording sheet is improved. |
