    摘要: Disclosed is a heat-sensitive recording material comprising a base sheet and a heat-sensitive record layer formed over the base sheet and comprising a colorless or pale-colored basic dye and a color developing material capable of forming a color when contacted with the dye, the heat-sensitive recording material being characterized in that the heat-sensitive record layer contains as the color developing material at least one multi-valent metal salt of an indole-2-carboxylic acid derivative represented by the formula ##STR1## wherein R.sub.1 through R.sub.6 are hydrogen or other substituent. The heat-sensitive recording material is resistant to plasticizer and diazo developer, and also is suitable for high-speed recording.
