Abstract

Solution à phase interne s'utilisant comme revêtement d'un matériau déchirable et s'appliquant sur une feuille de base pour obtenir un matériau d'enregistrement sensible à la pression. Cette solution comprend une ou plusieurs substances chromogènes dont au moins 90 % de celles-ci sont des dérivés de fluorane monoamino et/ou diamino dissous dans un solvant comprenant 80 % à 100 % d'une ou plusieurs huiles végétales et/ou animales. De préférence, les substances chromogènes comprennent uniquement des dérivés de fluorane monoamino et/ou diamino, et le solvant comprend uniquement une ou plusieurs huiles végétales et/ou animales. La dissolution des substances chromogènes dans le solvant se fait à une température comprise entre 100 DEG C et 135 DEG C, et les microcapsules contenant ce type de solution chromogène peuvent être produites par des procédés de coacervation classiques s'effectuant en dessous de 70 DEG C.
