Problems solved by technology

However, depending on the chemistry of the chosen phosphor, the color of the afterglow is limited to green, blue-green, or violet, and the daytime appearance of plastics containing these phosphors is an unaesthetic greenish-white or off-white

Embodiment 1-24

[0039] In each example, 227g resin was mixed with 22.7g LumiNova  G-300M Phosphorescent Phosphor Pigment, 0.023 g of respective polymer soluble dye mix. Pigment and dye powder with 10 drops (about 1g) of PARAPLEX  G-62 Epoxy Soybean Oil Premix. To this mixture was added 2.0 g ADVAWAX  280, then mixed in a Harbil mixer or paint shaker and injection molded at about 420°F. In Tables 1-5, the concentrations of resin, dye and phosphorescent pigment are expressed as a percentage of resin in the final product.

[0040] The resulting daylight and luminous colors are listed in the table. As illustrated, the glow-in-the-dark and daylight fluorescent colors are similar in each case, except for Examples 19-24, in which a magenta or violet fluorescent dye was used. In these examples, the glow-in-the-dark color is whitish, not purple.

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.

Description

Background of the invention [0001] The present invention relates to a phosphorescent plastic composition and product, which have bright and eye-catching daylight color fluorescence and strong noctilucent phosphorescence similar to daylight color. In particular, the present invention relates to the direct use of polymer-soluble fluorescent dyes and phosphorescent pigments to provide a wide range of daylight and luminous color colors tailored to user requirements. [0002] The use of phosphorescent substances in the production of luminescent materials is well known and has been used in a variety of "glow in the dark" items such as golf balls, rubber soles, many different toys, hard hats, bicycles to make them visible Seat belts, direction indicators and signs, background light sources for LCD clocks, etc. Phosphorescent materials have been reported to be used in vehicle components such as wheel air valve stem caps, the nighttime glow of the shift knob, or phosphorescent badges ...
