Abstract
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.
