Abstract

A credential, such as a passport or an identification card, is provided, for example, by printing, coating or impregnation, with a phosphorescent composition which includes at least two phosphorescence activators having different emission characteristics with respect to both wavelength (colour) and lifetime (duration) so that, when the credential has been irradiated, it exhibits an afterglow which appears to change colour with time. In the phosphorescent composition, the activators are conveniently incorporated in a urea-formaldehyde or melamine- formaldehyde resin. The credential may take the form of a paper core (2) carrying visible identification information (4, 5) and surrounded by laminated-on transparent plastics material (3) the inner surface (6) of which has been printed with a pattern in a phosphorescent ink the afterglow of which changes from green to blue over a few seconds. <IMAGE>
