CA 2533183

A coating composition containing a resinous binder with colorants and reflective pigments. The colorants absorb visible light at a first wavelength and produce fluorescent light at a second wavelength band when exposed to visible light. When applied to a substrate, the coating composition appears as one color on face from the specular reflection of the colorants off the reflective pigments and a different color on flop from the fluorescent light produced by the colorants.

Composition de revêtement contenant un liant résineux comportant des colorants et des pigments réfléchissants. Ces colorants absorbent la lumière visible à une première longueur d'onde et produisent de la lumière fluorescente à une deuxième bande de longueur d'onde quand ils sont exposés à la lumière visible. Quand elle est appliquée à un substrat, cette composition de revêtement présente une face monochrome sous l'effet de la réflexion spéculaire des colorants hors des pigments réfléchissants et une couleur différente métamérique sous l'effet de la lumière fluorescente produite par ces colorants.
