ABSTRACT:
A method of manufacturing a slip-resistant photo-luminescent device includes dispensing first and second powdered components into respective recesses (8, 13) provided in a substrate (7) such as a metal strip. The first powdered component includes a resin and a friction enhancing material, the second powdered component includes a resin and a photo-luminescent pigment. The powdered components are then heated (4) to fuse the resins and bond them to surfaces of the respective recesses (8, 13). A channel (15) is formed between the first and second recesses (8, 13) for receiving traces of the first and second components that may spill from the adjacent recesses.
