| titleOfInvention | Fluoran compound and recording material using this compound |
| abstract | (57) [Summary] [Object] To provide novel fluoran compounds and recording materials using these compounds. [Structure] General formula (I) (In the formula, R 1 and R 2 each independently represent an alkyl group having 1 to 8 carbon atoms, an alkoxyalkyl group having 3 to 8 carbon atoms or a phenyl group which may have a substituent, and R 1 and R 2 R 2 may combine with each other to form a pyrrolidino ring or a piperidino ring, R 3 represents an alkyl group having 1 to 6 carbon atoms, R 4 and R 5's each independently represent an alkyl group having 1 to 5 carbon atoms. ), And a recording material using the fluorane compound as an electron-donating color former. By using the fluorane compound according to the present invention as an electron-donating color former, a recording material having extremely high fastness to nitrogen oxide can be obtained. |
