Abstract

PURPOSE:To provide a heat-sensitive recording material which provides excellent image density without suffering from adhesive of scum to a thermal element, sticking phenomenon and piezochromic phenomenon, by incorporating a specific compound of xanthene series, acridine series, etc. in a heat-sensitive coloring layer. CONSTITUTION:At least one of compounds represented by formulaI, where X represents O, or S; Y1 represents H, lower alkyl, phenyl or benzyl, formula II, where Y2 represents H or lower alkyl, formula III, where Z represents O or S; Y2 represents H, OH, Cl, methyl or acetyl, formula IV, where Y4 represents H, OH or lower alkyl, and formula V, such as xanthene, acridine, dibenzo(thio) furan or phenanthrene, are incorporated, pref., in an amount of 0.1-5 times the weight of a dye in the heat-sensitive coloring layer containing a colorless or pale leuco dye (e.g.: crystal violet lactone) and an acidic or phenolic substance for coloring upon reaction with the dye by heating (e.g.: bisphenol A).
