| titleOfInvention | Reversible thermosensitive coloring composition and recording medium using the same |
| abstract | (57) [PROBLEMS] To provide a reversible color-forming composition and a reversible thermosensitive recording medium, which have stable color-forming property and decoloring property and can be used in a wide range of use conditions and have high light resistance. An electron-donating color-forming compound and an electron-accepting compound are contained as main components, and a relatively colored state and a decolored state are formed due to a difference in heating temperature and / or a cooling rate after heating. A reversible thermosensitive color-developing composition containing a chroman compound represented by the following general formula (1). Embedded image (In the general formula (1), R 1 represents hydrogen or a lower alkyl group, n represents 1 to 3, R 2 represents hydrogen, an unsubstituted or substituted alkyl group, a carboxylic acid and an alkyl ester thereof, R 3 represents hydrogen or an alkyl group, respectively) |
