Highly light-resistant fibers, and process for producing the fibers

摘要

A polymer for imparting light resistance to fibers is prepared by radical polymerizing a monomer composition including a specific ultraviolet stabilizable monomer and/or ultraviolet absorptive monomer. A highly light resistant fiber includes the light resistance imparting polymer inside or on the surface of the fiber. The polymer can impart a satisfactory light resistance to fibers over a long time, and the fiber is highly resistant to light.
