| abstract | PURPOSE:To contrive a higher response speed through utilizing a change between states other than a solid-liquid state change and ensure suitability for expressing an animation, by providing an electron-donative color-developing organic compound having a lactone ring and an alkylphenol being liquid at normal temperature. CONSTITUTION:An electron-donative color-developing organic compound having a lactone ring and an alkylphenol being liquid at normal temperature are provided. The organic compound per se is a colorless or light-colored coloring matter precursor (so-called leuco dye), and is developed into a color by opening of the lactone ring. The coloring matter precursor may be a triphenylmethanephthalide, a fluoran, a thiofluoran, an indolylphthalide, a Rhodamine lactam, an azaphthalide or the like. A color developer is required to have a relatively low capability of receiving an electron, be liquid at normal temperature and have the function of a medium the fluidity of which varies with temperature, so that the color developer is preferably a phenol with an alkyl chain introduced thereto at the para-position. The coloring matter precursor is capable of extremely rapid color formation and decoloration, thereby ensuring suitability for expressing an animation. |
