CA 2427664

A color effect material is composed of a plurality of encapsulated substrate platelets in which each platelet is encapsulated with copper, zinc, an alloy of copper, or an alloy of zinc first layer which acts as a reflector to light directed thereon, a second layer encapsulating the first layer in which the second layer provides an optically variable reflection of light impinging thereon and a third layer encapsulating the second layer and being selectively transparent to light directed thereon.

L'invention concerne un matériau à effet de couleur composé d'une pluralité de plaquettes de substrat encapsulées, chacune des plaquettes étant encapsulée avec une première couche de cuivre, de zinc, d'un alliage de cuivre ou d'un alliage de zinc, laquelle couche fait office de réflecteur de lumière; d'une seconde couche encapsulant la première couche; la seconde couche permettant une réflexion optiquement variable de la lumière incidente; et d'une troisième couche encapsulant la seconde couche et présentant une transparence sélective à la lumière dirigée sur sa surface.
