Title (EN) INK COATINGS FOR SECURITY DOCUMENTS TO PREVENT FORGERY BY MEANS OF HEAT SENSITIVE ERASABLE INK
(FR) REVÊTEMENTS D'ENCRE POUR DOCUMENTS DE SÉCURITÉ POUR EMPÊCHER LA FALSIFICATION AU MOYEN D'ENCRE EFFAÇABLE THERMOSENSIBLE
Abstract: front page image
(EN)Disclosed is a solvent-borne or UV-curable fugitive ink composition for application to a substrate that is to be provided with indicia. The ink composition comprises at least one halochromic compound and at least one filler compound and is capable of preventing indicia formed with a heat sensitive erasable ink on an area of the substrate carrying the fugitive ink composition and thereafter subjected to a thermal treatment from becoming invisible to an unaided eye.
(FR)L'invention porte sur une composition d'encre fugitive à base de solvant ou durcissable par UV destinée à être appliquée à un substrat qui est doté de marques. La composition d'encre comprend au moins un composé doté d'halochromie et au moins un composé charge et elle permet d'empêcher que des marques formées avec une encre effaçable thermosensible sur une zone du substrat portant la composition d'encre fugitive et après cela soumise à un traitement thermique ne deviennent invisibles à l'œil nu.
