Abstract
An optical fiber containing a polymer coating that includes a perlescent pigment. The perlescent pigment contains mica particles which transmit wavelengths of light used to cure the polymer coating. Further, the mica particles reflect visible wavelengths of light. Therefore, the inclusion of perlescent pigments in the polymer coating increases cure speed, due to increased UV transmittance, while enhancing the brightness or visibility of color in an optical fiber coating, due to reflection of visible light.
