Document Type and Number:
WIPO Patent Application WO2000027908
Kind Code:
A3
Abstract:
The invention provides compositions and molded, extruded or formed phosphorescent plastic articles produced therefrom that contain non-radioactive, non-sulfide phosphorescent phosphor pigments that emit light in the visible spectrum, preferably metal oxide aluminate:europium-activated phosphorescent phosphor pigments, preferably in combination with polymer-soluble daylight fluorescent dyes, in transparent or translucent resins. The plastic articles produced from the compositions of the invention exhibit a remarkably rich, attractive, clear, brilliant fluorescent daylight color and a strong, long-lasting glow-in-the-dark luminescence having a color similar to that of the daylight color.
