Pyridylethylaminofluorans |
| abstract |
2- and/or 6-pyridylethylamino-substituted fluorans useful as color formers, particularly in pressure-sensitive carbonless duplicating systems and thermal-responsive marking systems are prepared by the interaction of (pyridylethylaminophe- nyl)carbonylbenzoic acids with 4-hydroxy- or alkoxyanilines or by the interaction of (disubstituted aminophenyl)carbonylben- zoic acids with N-pyridylethyl-4-hydroxy- or alkoxy acetanilides. The (pyridylethylaminophenyl)carbonylbenzoic acid intermediates required for the fluorans are prepared by interacting a N-pyridylethyl-3-hydroxyaniline with a substituted or unsubstituted phthalic anhydride. The N-pyridylethyl-4-hydroxy-or alkoxyanilines and the N-pyridylethyl-3-hydroxyanilines are prepared by interacting the respective aniline with a vinylpyridine. |
