Gegenstände, die dauerhafte Fluoreszenz zeigen

摘要

Retroreflective article (10) comprising an ultraviolet screening screen layer (18) and a color layer (12) containing a defined daylight fluorescent dye dissolved in a defined polymeric matrix. The article exhibits durable fluorescence and resistance to degradation from exposure to sunlight. If desired, the article can be made retroreflective by forming retroreflective elements (20) in the color layer.
