HEAT-SENSITIVE RECORDING MATERIAL HAVING A SECURITY FEATURE
(FR)
MATÉRIAU D'ENREGISTREMENT THERMOSENSIBLE À CARACTÉRISTIQUE DE SÉCURITÉ
Abstract:
(DE)
Ein wärmeempfindliches Aufzeichnungsmaterial umfasst ein Trägerpapier mit einer auf einer Seite angeordneten wärmeempfindlichen Aufzeichnungsschicht. In das Trägerpapier ist ein partikulärer, wasserunlöslicher Azofarbstoff und/oder Planchetten eingearbeitet, in denen ein partikulärer, wasserunlöslicher Azofarbstoff dispergiert ist. Alternativ oder zusätzlich ist in der wärmeempfindlichen Aufzeichnungsschicht ein partikulärer, wasserunlöslicher Azofarbstoff dispergiert. Wird das Papiererzeugnis im Zuge eines Manipulationsversuches mit organischen Lösungsmitteln behandelt, so werden die Farbstoffpartikel gelöst. Das Aufzeichnungsmaterial wird intensiv verfärbt und der Manipulationsversuch irreversibel angezeigt.
(EN)
The invention relates to a heat-sensitive recording material, comprising a substrate paper having a heat-sensitive recording layer arranged on one side. A particulate, water-insoluble azo dye and/or planchettes in which a particulate, water-insoluble azo dye is dispersed are embedded in the substrate paper. Alternatively or additionally, a particulate, water-insoluble azo dye is dispersed in the heat-sensitive recording layer. If the paper product is treated with organic solvents in the course of a manipulation attempt, the dye particles are dissolved. The recording material is intensely discolored, and the manipulation attempt is irreversibly indicated.
(FR)
L'invention concerne un matériau d'enregistrement thermosensible qui comprend un papier support muni d'une couche d'enregistrement thermosensible disposée sur un côté. Un colorant azoïque particulaire et insoluble dans l'eau et/ou des planchettes dans lesquelles un colorant azoïque particulaire et insoluble dans l'eau est dispersé, sont intégrés dans le papier support. En variante ou en supplément, un colorant azoïque particulaire et insoluble dans l'eau est dispersé dans la couche d'enregistrement thermosensible. Lorsque le produit en papier est traité avec des solvants organiques dans le cadre d'une tentative de manoeuvre frauduleuse, les particules de colorant sont dissoutes. Le matériau d'enregistrement est coloré de façon intensive et la tentative de manoeuvre frauduleuse est affichée de façon irréversible.
