Title (EN) ANTI−STOKES FLUORESCENT MATERIAL COMPOSITION
(FR) COMPOSITIONS DE MATIERE FLUORESCENTE ANTI-STOKES
Abstract: front page image
(EN)The invention relates to anti−Stokes fluorescent material compositions which, upon excitation by IR radiation, for their part emit IR radiation without significant quantities of visible blue light being emitted at the same time, and which are therefore suitable as invisible security marks.
(FR)L'invention concerne des compositions de matière fluorescente anti-stokes qui, lors d'une excitation au moyen d'un rayonnement IR, émettent un rayonnement IR, sans que des quantités significatives de lumière bleue visible ne soient émises simultanément, et qui sont par conséquent appropriées en tant que marques de sécurité invisibles.
