Abstract To provide a thermal recording material that is less malodorous in forming an image part even though it uses kraft lignin as a developer.SOLUTION: A thermal recording material includes a support, and a thermal coloring layer provided on the support. The thermal coloring layer includes (A) a coloring substance, (B) kraft lignin with a dimethyl disulfide content of 2.5 ppm or less, and (C) a specific developer.SELECTED DRAWING: None 【課題】クラフトリグニンを顕色剤として用いながらも画像部を形成するときに不快臭を感じにくい感熱記録材料を提供すること。【解決手段】支持体と、支持体上に設けられた感熱発色層と、を備え、感熱発色層が、（Ａ）発色物質と、（Ｂ）ジメチルジスルフィドの含有量が２．５ｐｐｍ以下であるクラフトリグニンと、（Ｃ）特定の顕色剤と、を含む、感熱記録材料。【選択図】なし
