Patent

CA 2209480

A light-stable colored composition which includes a colorant and a radiation transorber. The colorant, in the presence of the radiation transorber, is adapted, upon exposure of the transorber to specific, narrow bandwidth radiation, to be mutable. The radiation transorber also imparts light- stability to the colorant so that the colorant does not fade when exposed to sunlight or artificial light.

Une composition colorée photostable comprend un colorant et un agent de transorption de rayonnement. Le colorant, en présence de l'agent de transorption de rayonnement, est adapté pour pouvoir être muté, lors de l'exposition de l'agent de transorption à un rayonnement à largeur de bande étroite spécifique. L'agent de transorption de rayonnement confère également une photostabilité au colorant de sorte que ce dernier ne perde pas de sa couleur lorsqu'il est exposé au rayonnement solaire ou à la lumière artificielle.
