ABSTRACT:
The surface-coated optical fiber of the invention is composed of a fibrous body of a vitreous material, e.g. fused quartz glass, and a coating layer thereon formed of a coating composition comprising an organosiloxane-modified organic polymer, of which the backbone is formed of recurring organic units such as a polybutadiene, an acrylic polymer and the like having modifying pendant groups containing an organosiloxane unit. The workability of the coating composition in the coating application is excellent so that a high uniformity is obtained in the coating layer in comparison with a coating composition comprising an unmodified organic polymer. The coating layer thus formed has a remarkably improved mechanical strength over a coating layer formed of an organopolysiloxane resin alone.
