PURPOSE:To obtain a heat-sensitive recording sheet by jointly using benzyl p-benzyl oxybenzoate and a wax in addition to benzyl p-hydroxybenzoate as a developer for a dye precursor. CONSTITUTION:The dispersions of a dye precursor (A) (e.g., Crystal violet lactone, etc.), 10-60wt% (based on developer) benzyl p-oxybenzoate and benzyl p-hydroxybenzoate (B) as the developer, and 10-100wt%, preferably 10-60wt%, a wax (C) (e.g., stearic amide, etc.) having a melting point of 60-110 deg.C are mixed together to obtain a coating liquid. The coating liquid is coated on a supporter to obtain an objective sheet. |
