摘要：
PROBLEM TO BE SOLVED: To provide a heat-sensitive recording material which shows the high shelf stability of a texture part and especially, hardly develops a color by a solvent. SOLUTION: This heat-sensitive recording material is composed of a heat- sensitive color developing layer containing a leuco dye and a developer which makes the leuco dye develop a color during heating, formed on a support. In this recording material, a chemical compound having at least two groups represented by formula (1) per molecule, -SO2 -NHNH2 , is used as a developer.
