A curable, powder-based coating composition is disclosed. The coating composition is utilized for coating a substrate, having a first color effect, with a film layer of the coating composition. Application of the film layer to the substrate produces a second color effect different from the first color effect of the substrate. The coating composition includes a powder-based binder. The powder-based binder is the reaction product of a resin and a cross- linking agent. More specifically, the resin has a functional group and the cross-linking agent is reactive with the functional group of the resin. The coating composition also includes a color effect-providing pigment. The color effect-providing pigment includes a pigment substrate and an inorganic coating. More specifically, the pigment substrate has first and second substantially parallel and planar surfaces, and the inorganic coating is disposed on at least one of the first and second substantially parallel and planar surfaces, and the inorganic coating is disposed on at least one of the first and second substantially parallel and planar surfaces of the pigment substrate. Furthermore, the inorganic coating disposed on the pigment substrate has an index of refraction of 1.8 or less.
La présente invention concerne une composition de revêtement durcissable à base de poudre, qui est utilisée pour revêtir un substrat possédant un premier effet de couleur d'une couche mince de la composition de revêtement de l'invention. L'application de la couche mince sur le substrat produit un second effet de couleur, différent du premier effet de couleur du substrat. La composition de revêtement précité comprend un liant à base de poudre, qui est le produit de la réaction d'une résine et d'un agent de réticulation. En particulier, la résine comprend un groupe fonctionnel, avec lequel l'agent de réticulation est capable de réagir. La composition de revêtement de l'invention comprend également un pigment à effets de couleur, qui comprend un substrat de pigment et un revêtement inorganique. En particulier, le substrat de pigment possède une première et une seconde surface plane sensiblement parallèles, et le revêtement inorganique est disposé sur la première et/ou la seconde surface plane sensiblement parallèles du substrat de pigment. En outre, le revêtement inorganique placé sur le substrat de pigment possède un indice de réfraction inférieur ou égal à 1,8.
