Summary:To provide a heat-sensitive recording material of which plasticizer resistance deficient in N,N'-di-(3-(p-toluenesulfonyloxy)phenyl) urea as a color developer is improved.SOLUTION: There is provided a heat-sensitive recording material in which a mass ratio between N,N'-di-(3-(p-toluenesulfonyloxy)phenyl)urea as developer and a total amount of N-(m-tolylaminocarbonyl)-phenylalanine and N-(phenylaminocarbonyl)-phenylalanine as co-developers is 19:1 to 1:2.SELECTED DRAWING: None 【課題】顕色剤としてＮ，Ｎ'－ジ－（３－（ｐ－トルエンスルホニルオキシ）フェニル）尿素に足りない耐可塑剤性を向上させた感熱記録材料を提供する。【解決手段】顕色剤としてＮ，Ｎ'－ジ－（３－（ｐ－トルエンスルホニルオキシ）フェニル）尿素と、助顕色剤としてＮ－（ｍ－トリルアミノカルボニル）－フェニルアラニンおよびＮ－（フェニルアミノカルボニル）－フェニルアラニンの合計量との質量比が、１９：１～１：２であることを特徴とする感熱記録材料。【選択図】なし
