Abstract
A plastic optical fiber having an enhanced light transmission and satisfactory mechanical and chemical properties is composed of a core having a refractive index n.sub.1, a cladding layer having a refractive index n.sub.2, and a protective layer having a refractive index n.sub.3, the refractive indices n.sub.1, n.sub.2, and n.sub.3 satisfying the relationships EQU n.sub.1 -n.sub.2 .gtoreq.0.01 and EQU n.sub.3 -n.sub.2 >0 and the cladding layer being composed of a copolymer of: PA0 (A) 20% to 99.95% by weight of at least one comonomer selected from fluoroalkyl acrylates and methacrylates, PA0 (B) 0.05% to 10% by weight of at least one vinyl comonomer having a hydrophilic radical, and PA0 (C) 0% to 79.95% by weight of at least one other vinyl comonomer capable of copolymerizing with the comonomers (A) and (B).
