Abstract (en)

[origin: WO9214173A1] Flexible visibility enhancing material (20) is provided which combines the advantages of a light reflective component and a luminescent component. The material includes a first layer of prismatic light reflective plastic material (22) having an underlying surface formed with a plurality of minute prism-like formations (24) projecting therefrom at regular spaced intervals and an overlying substantially smooth light transmissive surface (28). Bonded as by heat sealing to the first layer is a second layer of plastic luminescent material (34) contiguously and integrally attached to the underlying surface of prism-like formations and generally coextensive therewith. The visibility enhancing material simultaneously radiates luminescent light from the second layer through the underlying surface of prism-like formations and through the smooth light transmissive surface and reflected light from the prism-like formations through the smooth light transmissive surface. In one embodiment, a leash for controlling and restraining a pet animal includes a flexible elongate member comprised of the visibility enhanced material. In another embodiment, the second layer is replaced with a layer of luminescent material (56) which can be selectively energized to become luminous.
