| titleOfInvention | Fluoran derivative, production thereof and recording material using the same |
| abstract | NEW MATERIAL:Fluoran derivatives of formula I , wherein R is cycloheptyl, etc.; R 1 , R 2 , R 3 are each H, (halogen, etc.-substd.) C 1 WC 18 alkyl, (halogen, etc.-substd.) aralkyl; R 2 and R 3 form an N-hetero ring when combined together, the N-hetero ring may contain an O or N atom as a ring member; R 3 also represents (halogen, etc.-substd.) aryl; X, Y are each H, halogen, etc. n EXAMPLE: 3-N-methyl-N-cyclobutylamino-6-methyl-7-toluidinofluoran. n USE: Compounds useful for the production of pressure-sensitive, thermal recording materials excellent in stability before color development and exhibiting excellent developing rate, developing density, fastness, etc. n PREPARATION: A 2-(2-hydroxy-4-substd. amino)-benzoyl benzoic acid derivative of formula II (wherein R, R 1 are as defined above) is reacted with a p-aminophenol derivative of formula III (wherein R 2 , R 3 , R 4 , X, Y are as defined above) to produce the fluoran derivative of formula I . n COPYRIGHT: (C)1984,JPO&Japio |
