    • The present invention provides a highly reflective fluorescent polymer composition comprising a benzoxzolyl naphthalene optical brightener and a polymeric substrate support material formed into three dimensional articles or fibers. The enhanced light reflectivity of the instant compositions occurs over a wavelength range of from about 400 to 700 nanometers. The fiber embodiment comprises a body or support portion made of a flexible and durable thermoplastic material which is at least partially translucent and bis(benzoxazolyl)napthalenes optical brightener molecularly dispersed throughout the polymeric body potion of the fiber. The fibers are fluorescent to a UV source and can be effectively utilized for artificial hair for toy dolls as well as for various other textile applications.
    • 本发明提供了一种高反射荧光聚合物组合物,其包含苯并唑基萘荧光增白剂和形成三维制品或纤维的聚合物基材载体材料。 本发明组合物的增强的光反射率在约400至700纳米的波长范围内发生。 纤维实施方案包括由至少部分半透明的柔性耐久的热塑性材料制成的主体或支撑部分,以及分子分散在纤维聚合物体部分的双(苯并恶唑基)萘荧光增白剂。 纤维对UV源是荧光的,并且可以有效地用于玩具娃娃的人造毛发以及各种其它纺织品应用。
