Abstract
A heat-sensitive recording material includes a support having disposed thereon a heat-sensitive color-forming layer that includes an electron-donating leuco-dye, an electron-receiving compound and an UV absorbent, wherein the layer contains 4-hydroxybenzenesulfonanilide as the electron-receiving compound. Because the layer includes 4-hydroxybenzenesulfonanilide, the heat-sensitive recording material has high sensitivity and improved image preservability, chemical resistance and sticking resistance.
