Patent

CA 2573738

The invention concerns a method for marking a material characterized in that it consists in incorporating into the material: either a phosphor capable of producing, following excitation, two light emissions whereof the respective wavelengths and the emission decay times are different, or several phosphors capable of producing, following excitation, a light emission whereof the wavelength and the emission decay time are different from the wavelength and emission decay time of the other or other phosphors. The material can in particular be of the paper, board, paint, textile, ink, glass or macromolecular material type.

Le procédé de marquage d'un matériau selon l'invention est caractérisé en ce qu'on incorpore dans le matériau - soit un luminophore apte à produire, après excitation, deux émissions de lumière dont les longueurs d'onde et les temps de déclin de l'émission respectifs sont différents; - soit plusieurs luminophores aptes à produire, chacun, après excitation, une émission de lumière dont la longueur d'onde et le temps de déclin de l'émission sont différents de la longueur d'onde et du temps de déclin de l'émission de l'autre ou des autres luminophores. Le matériau peut être notamment du type papier, carton, peinture, textile, encre, verre ou matériau macromoléculaire.
