CA 2428697

A color-tailorable, surface-metalized, pigmented optical body comprising a single or multiple layer polymeric core comprising at least one layer of a thermoplastic polymer material having dispersed therein a particulate pigment, and a metallic layer located on at least one outer surface of the polymeric core. The optical bodies are generally constructed such that the at least one of the L*, a*, and b* color scales of the polymeric core differs from the L*, a*, and b* color scales of the metallic layer.

L'invention concerne un corps optique pigmenté, à couleurs modulables et métallisé en surface, comprenant un noyau polymère à une ou plusieurs couches dont au moins une couche de matériau polymère thermoplastique contenant des pigments particulaires dispersés, et une couche métallique appliquée sur au moins une surface extérieure du noyau polymère. Les corps optiques sont en général conçus de telle manière qu'au moins une des gammes de couleurs L*, a* et b* du noyau polymère est différente des gammes de couleurs L*, a* et b* de la couche métallique.
