<p>A plastic optical fiber having an enhanced light transmission and satisfactory mechanical and chemical properties is composed of a core having a refractive index n1, a cladding layer having a refractive index n2, and a protective layer having a refractive index n3, the refractive indices n1, n2, and n3 satisfying the relationships n1-n2>/=0.01 and n3-n2>0 and the cladding layer being composed of a copolymer of: (A) 20% to 99.95% by weight of at least one comonomer selected from fluoroalkyl acrylates and methacrylates, (B) 0.05% to 10% by weight of at least one vinyl comonomer having a hydrophilic radical, and (C) 0% to 79.95% by weight of at least one other vinyl comonomer capable of copolymerizing with the comonomers (A) and (B).</p> |
