| titleOfInvention | Fluoran derivative, its preparation, and recording medium prepared by using it |
| abstract | NEW MATERIAL:A fluoran derivative of formula I [where R 1 and R 2 each are H, an alkyl of 1W8C, an alkoxyalkyl, an alkenyl, an (alkyl-substituted) phenyl or an (alkyl-substituted) cycloalkyl; R 1 and R 2 may form heterocyles with N; R 3 is an alkyl of 1W4C; X and Y each are a halogen, an alkyl of 1W4C or an alkoxy of 1W2C]. n USE: A color former (a basic dye) used in a pressure-sensitive recording medium, a thermal recording medium, etc. Essentially it is colorless or has a light color. When in contact with a developer it will form a high-density black color. n PREPARATION: It is prepared by the condensation of a 2-(2-hydroxy-4-amino) benzoylbenzoic acid derivative of formula II with a diphenylamine derivative of formula III. n COPYRIGHT: (C)1985,JPO&Japio |
