Abstract
L'invention concerne le 3-N-isobutyl-éthylamino-5-phénylaminofluorane qui est un colorant chromogène engendrant une teinte verte d'une nouvelle espèce. On l'utilise ainsi qu'une substance acide pour la confection de matières d'enregistrement chromogènes à utiliser dans du papier à copier sensible à la pression, du papier d'enregistrement sensible à la chaleur et analogues.
