| titleOfInvention | Fluoran derivative, its preparation, and recording medium made by using same |
| abstract | NEW MATERIAL:A fluoran derivative of formula I (wherein R 1 is H; R 2 is a halogen, an alkoxyl or a 1W8C alkyl; R 3 is a halogen, a lower alkyl, an aralkyl, etc.; Y is a lower alkoxyl). n USE: A colorless to light color basic dye. It shows an excellent effect especially when used in various recording mediums to which a color reaction with a developer is applied. n PREPARATION: A 2-(2-hydroxy-4-substituted amino)benzoylbenzoic acid derivative of formula II is reacted with a p-aminophenol derivative of formula III (wherein R 4 is H or a lower alkyl; X is H, a halogen or a lower alkyl; Y is an alkoxyl) to give an objective compound. As a condensation agent in the reaction of a compound of formula II with a compound of formula III, sulfuric acid is preferably used, also serving as a solvent. n COPYRIGHT: (C)1986,JPO&Japio |
