Abstract
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.
