ABSTRACT:
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.
