CA 2178843
A coating composition is described comprising a polymer resin binder and optically variable thin film pigment flakes. The pigment flakes have a multilayer thin film interference structure comprising a metal reflector layer having first and second parallel planar surfaces and, disposed on at least one of said first and second planar surfaces, at least one transparent dielectric layer. The coating composition further comprises a black pigment. This coating composition can be used to prepare a variety of coatings, especially color-plus-clear composite coatings such as those used in the automotive industry.
Composition pour revêtements comprenant une résine polymère comme liant et des pigments floculeux optiquement variables en couches minces. Les pigments floculeux présentent une structure interférentielle de plusieurs couches minces dont une couche métallique réflectrice à deux surfaces planes parallèles dont l'une au moins est revêtue d'une couche d'un diélectrique transparent. Ladite composition comprend de plus un pigment noir. Cette composition peut servir à préparer divers revêtements composites notamment ceux du type couleur-plus-transparence utilisés dans l'industrie automobile.
