Abstract

Un matériau pour effectuer des tracés ou des copies est constitué d'un avant-produit de colorant noyé dans un liant et d'un composé acide qui réagit avec cet avant-produit. Le composant acide est constitué par un chlorure d'un métal dont la masse atomique est comprise entre 50 et 66, ce chlorure se présentant à l'état solide et étant emprisonné dans des microcapsules. Application : matériau à une ou deux feuilles, du genre papier carbone.
