Abstract
A heat-sensitive recording material comprising a support having provided thereon a heat-sensitive color-forming layer which contains a colorless or slightly colored electron-donating dye precursor and an electron-accepting compound capable of reacting with the electron-donating dye precursor to form color, wherein the heat-sensitive color-forming layer further contains at least one of the compounds represented by the general formulae (I) to (VI) shown in the specification and at least one of the compounds represented by the general formulae (VIII) to (XII) shown in the specification, or wherein the heat-sensitive color-forming layer further contains about 0.5 wt % to less than about 20 wt %, based on the electron-accepting compound, of the compound represented by the general formula (XIII) shown in the specification. The heat-sensitive recording material obtained provides a high density color image and does not undergo a decrease in heat responsibility and an increase in background fog formation.
