Abstract
Abstract A decorative ribbon or sheet material exhibiting desirable aesthetic qualities. The decorative sheet material, since it comprises a plastic film having a convex cylindrical lens embossment on its top surface and a light diffusing embossment on its bottom surface and since it further comprises a colored reflective coat or coats adhered to the bottom surface, exhibits aesthetic improvements over conventional foam-oriented polypropylene-based ribbons. Specifically, the decorative material exhibits improved color intensity and improved balance of specular and diffuse reflection.
