A thermosensitive reversible color-developing and disappearing agent includes an aromatic compound having at least one group of the formula, -SO₂NHCXNH-, wherein X = O or S atom, and at least one straight chain alkyl group with 11 or more carbon atoms, and is reactive with a dye precursor in a thermosensitive recording material to thereby record colored images on the recording material upon heating imagewise, and make the colored images disappear upon heating to a temperature lower than the colored image-forming temperature.
一种热敏可逆显色剂和消失剂包括一种芳香族化合物,该化合物至少具有一个式-SO₂NHCXNH-的基团,其中 X = O 或 S 原子,以及至少一个具有 11 个或更多碳原子的直链烷基,并与热敏记录材料中的染料前体发生反应,从而在图像加热时在记录材料上记录彩色图像,并在加热到低于彩色图像形成温度时使彩色图像消失。
