Abstract
Heat-sensitive recording materials comprising a colorless or light-colored dye precursor and a color developer capable of developing a color of the dye precursor, upon reaction with said dye precursor with heating, further contain as sensitizers specific styryl-containing compounds. By incorporating these specific sensitizers, the heat-sensitive recording materials provide excellent thermal response and high sensitivity.
