Summary:PROBLEM TO BE SOLVED: To provide a thermosensitive recording medium which has high recording density and is excellent in plasticizer resistance of a recording part.SOLUTION: There is provided a thermosensitive recording medium which has a thermosensitive recording layer containing at least a leuco dye and a coloring agent on a support. The thermosensitive recording medium contains at least one selected from diphenylsulfone crosslinked type compounds represented by a general formula and N-[2-(3-phenylureido)phenyl]benzenesulfonamide as a coloring agent. The diphenylsulfone crosslinked type compound is preferably contained in a ratio of 0.1 to 2.5 pts.mass based on 1 pt.mass of N-[2-(3-phenylureido)phenyl]benzenesulfonamide. 【課題】本発明は、記録濃度が高く、記録部の耐可塑剤性に優れた感熱記録体を提供することを主な目的とする。【解決手段】支持体上に、少なくともロイコ染料及び呈色剤を含有する感熱記録層を有する感熱記録体において、呈色剤として、一般式で表されるジフェニルスルホン架橋型化合物から選ばれる少なくとも１種、及びＮ−[２−(３-フェニルウレイド)フェニル]ベンゼンスルホンアミドを含有することを特徴とする感熱記録体。Ｎ−[２−(３-フェニルウレイド)フェニル]ベンゼンスルホンアミド１質量部に対して、ジフェニルスルホン架橋型化合物を０．１〜２．５質量部の比率で含有することが好ましい。【選択図】なし
