Title (EN) NEAR INFRARED (NIR) LASER MARKABLE COMPOSITIONS
(FR) COMPOSITIONS POUVANT ÊTRE MARQUÉES AU MOYEN D'UN LASER PROCHE INFRAROUGE (NIR)
Abstract:
(EN) A laser markable composition is provided that has an improved stability towards the environment. The improved stability has been realized by using specific Near Infrared absorbing compounds.
(FR) L'invention concerne une composition pouvant être marquée au laser, présentant une stabilité améliorée vis-à-vis de l'environnement. Cette amélioration de stabilité a été obtenue au moyen de composés spécifiques absorbant le rayonnement proche infrarouge.
