Summary:To realize high optical density and high light fastness without the occurrence of scumming in a heat-sensitive transfer sheet using a yellow dye having a specific structure or a magenta dye having a specific structure.SOLUTION: The sheet for the heat-sensitive transfer recording has a base material and a coloring material layer formed on the base material and contains a compound represented by formula (1) as given below and a specific dye compound in the coloring material layer. [In formula (1), R11 and R13 each independently represent a hydrogen atom, an alkyl group, an aralkyl group, an unsubstituted aryl group or an aryl group having a substituent; and R12 and R14 to R18 each independently represent a hydrogen atom or an alkyl group.]SELECTED DRAWING: None 【課題】特定の構造を持ったイエロー染料または特定の構造を持ったマゼンタ染料を用いた感熱転写シートにおいて、地汚れを発生することなく、高い光学濃度、高い耐光性を実現する。【解決手段】基材と、該基材の上に形成された色材層とを有し、該色材層に下記式（１）で表される化合物と特定の染料化合物とを含有する感熱転写記録用シート。［式（１）中、Ｒ１１及びＲ１３は、それぞれ独立して、水素原子、アルキル基、アラルキル基、無置換のアリール基または置換基を有するアリール基を表し、Ｒ１２、Ｒ１４〜Ｒ１８は、それぞれ独立して、水素原子またはアルキル基を表す。］【選択図】なし
