REVERSIBLY THERMOCHROMIC COMPOSITION |
| 摘要 |
[Object] To provide a reversibly thermochromic composition free from accidental discoloration by heat conducting from the opposite side writing surface or by self-heating due to quick writing; and also to provide a solid writing material and a writing ink composition comprising that composition.;[Means to solve the problem] A reversibly thermochromic composition comprising a combination of: (a) a reversibly thermochromic component capable of being discolored or decolored by heat and (b) a component for controlling heat conducting to the reversibly thermochromic component; and also a solid writing material and a writing ink composition comprising that composition. |

1. A reversibly thermochromic composition comprising a combination of
(a) a reversibly thermochromic component containing
(a1) an electron-donative coloring organic compound,(a2) an electron-accepting compound, and(a3) a reaction medium for reversibly causing an electron transfer reaction between the components (a1) and (a2) in a specific temperature range; and (b) a component for controlling heat conducting to the reversibly thermochromic component. |
