A method of marking an article to enable its identification, by applying to the article a conductive path, which is at least partially coated with a dye layer of at least one compound selected from voltage sensitive fluorescent dye (VSFD), mixture of such dyes, electro luminescent (EL) compound, OLED compound or mixtures thereof, the dye layer being excitable to emit fluorescent radiation, which serves to identify the article.

Une méthode de marquer un article pour permettre son identification, en appliquant à l'article un chemin conducteur, qui au moins est partiellement enduit d'une couche de colorant au moins d'un composé a choisi parmi le colorant fluorescent sensible de tension (VSFD), mélange de tels teint, composé luminescent d'électro (EL), composé d'OLED ou mélanges, la couche de colorant étant excitable émettre le rayonnement fluorescent, qui sert à identifier l'article.
