COLORED RETROREFLECTIVE ARTICLES
摘要:
Retroreflective articles include a layer of optical elements, the layer of optical elements being divided into at least a first segment (110) and second segment (120), and a bead bond layer (170) containing a colorant. The optical elements are partially embedded in the bead bond layer. The optical elements include transparent microspheres (140), a transparent polymeric layer (180), and at least one reflective layer. In the first segment of optical elements, the reflective layer is a dielectric reflective layer (150), and in the second segment of optical elements, the reflective layer is a reflective metallic layer (160). The retroreflective articles have improved wash durability.
