Fluoran compound, its production and recording material containing the compound |
| abstract |
NEW MATERIAL:The compound of formula I (R 1 is methyl or ethyl). n EXAMPLE: 3-N-2'-methoxyethyl-N-allylamino-6-methyl-7-anilinofluoran. n USE: A color-developing compound for recording material such as pressure- sensitive recording material or heat-sensitive recording material. n PREPARATION: The objective compound can be produced by reacting a benzoic acid derivative of formula II (R 2 is methyl or ethyl) [e.g. 2-(4'-N-2"-methoxyethyl- N-allylamino-2'-hydroxybenzoyl)benzoic acid] with a diphenylamine derivative of formula III (R 3 is lower alkyl) (e.g. 4-methoxy-2-methyldiphenylamine). n COPYRIGHT: (C)1991,JPO&Japio |
