Title (EN) IMPROVEMENTS IN AND RELATING TO SECURITY PRINTING
(FR) AMELIORATIONS DANS ET RELATIVES A L'IMPRESSION DE SECURITE
Abstract:
(EN) A composition comprising a mixture of a thermographic compound and a compound capable of undergoing a change in at least one optical property upon application of a stimulus is described. Also described are a printed image precursor comprising a substrate on at least a portion of which is coated such a composition, a method of manufacturing a printed image precursor and a method of manufacturing a printed image.
(FR) L'invention concerne une composition comportant un mélange d'un composé thermographique et d'un composé dont au moins une propriété optique est susceptible de subir un changement suite à l'application d'un stimulus. L'invention concerne également un précurseur d'image imprimée comportant un substrat dont au moins une partie reçoit un revêtement d'une telle composition, un procédé de fabrication d'un précurseur d'image imprimée et un procédé de fabrication d'une image imprimée.
