| titleOfInvention | Production of fluoran compound |
| abstract | PURPOSE: To readily obtain the subject compound useful as an electron donative colorless dye by reacting a halogen-substituted fluoran compound with a phenolic compound. n CONSTITUTION: A fluoran compound having a halogen atom in a substituent group [preferably a compound expressed by the formula (R 1 and R 4 represent alkyl, alkenyl, aryl, H, etc.; R 2 represents halogenoalkyl; R 3 and R 5 represent alkyl, alkenyl, aryl, H, halogen, etc.; ring A represents aromatic ring optionally containing a heteroatom)] is reacted with a phenolic compound {preferably a compound expressed by the formula Ar-XH [Ar represents (substituted) aromatic ring; X represents O or S]} to afford the objective compound {e.g. 2- anilino-3-methyl-6-N-ethyl-N-[3-(4-methyl-thiophenoxy)propyl]aminofluoran, etc.}. n COPYRIGHT: (C)1991,JPO&Japio |
