    • An article exhibiting durable fluorescent properties comprising a polymeric matrix, dye, and hindered amine light stabilizer, wherein the polymeric matrix is comprised of polycarbonate and the dye is comprised of a dye selected from the group consisting essentially of thioxanthone, perylene imide and/or thioindigoid compounds. The article exhibits durable fluorescence which resists degradation by ultraviolet or visible radiation. The invention is optionally combined with retroreflective elements so that the resultant article has durable fluorescent properties when exposed to sunlight and is also retroreflective. A method of manufacturing an article exhibiting durable fluorescent properties is also disclosed along with a method of increasing the durability of polycarbonate in a dyed system.
    • 一种表现出持久的荧光特性的制品,其包含聚合物基质,染料和位阻胺光稳定剂,其中聚合物基质由聚碳酸酯组成并且染料由选自基本上为噻吨酮,苝酰亚胺和/或硫代靛类的染料组成 化合物。 该制品表现出耐久的荧光,其抵抗紫外线或可见光辐射引起的降解。 本发明任选地与逆向反射元件组合,使得所得制品在暴露于阳光下时具有耐久的荧光特性并且也是逆向反射的。 还公开了制造具有耐用荧光性能的制品的方法以及增加染色体系中聚碳酸酯耐久性的方法。
