| titleOfInvention | Fluoran derivative, production thereof and recording medium using said derivative |
| abstract | NEW MATERIAL:Fluoran derivatives of formula I , wherein R 1 , R 2 , R 3 are each H, (halogen, alkoxy-cyano-substd.) 1W18C alkyl, (halogen, alkyl, alkoxy-substd.) aralkyl group, R 2 and R 3 may be combined together to form a heterocyclic ring; X is H, halogen, alkyl; Y is X, a lower alkoxy group. n EXAMPLE: 3-N-Ethyl-N-cyclopentylamino-6-methyl-7-anilinofluoran. n USE: Black color forming materials (color former) used for recording materials such as pressure-sensitive, thermal recording sheets. n PREPARATION: A 2-(2-hydroxy-4-cyclopentylamino)-benzoyl benzoic acid derivative of formula II is condensed with a p-aminophenol derivative of formula III in the presence of a condensing agent such as sulfuric acid. n COPYRIGHT: (C)1984,JPO&Japio |
