  A carboxylate is herein disclosed which is represented by the formula (1) or (2) wherein a ring X is an aromatic residue which may have a substituent; A is =NH or -(OR³ or OR⁴) (wherein each of R³ and R⁴ is independently an alkyl group having 1 to 8 carbon atoms which may have a substituent, and R³ and R⁴ may bond to each other to form a ring); R¹ is a hydrogen atom, an alkyl group having 1 to 20 carbon atoms which may have a substituent, an aralkyl group which may have a substituent, or an aryl group which may have a substitutent, but when A is =NH, R¹ is an aryl group which may have a substituent; and R² is an alkyl group having 1 to 8 carbon atoms which may have a substituent. A heat-sensitive recording material comprising this carboxylate is excellent in the stability of the color image and can provide an optically character-readable sharp color image.

  本文公开了一种羧酸盐，由式（1）或（2）表示 其中环 X 是可具有取代基的芳香残基；A 是＝NH 或-(OR³ 或 OR⁴)（其中 R³ 和 R⁴ 各自独立地是具有 1 至 8 个碳原子的烷基，可具有取代基，且 R³ 和 R⁴ 可相互键合形成环）；R¹是氢原子、具有 1 至 20 个碳原子的烷基（可带有取代基）、芳烷基（可带有取代基）或芳基（可带有取代基），但当 A =NH 时，R¹是芳基（可带有取代基）；以及 R² 是具有 1 至 8 个碳原子的烷基（可带有取代基）。由这种羧酸盐组成的热敏记录材料在彩色图像的稳定性方面非常出色，可以提供光学字符可读的清晰彩色图像。
