Abstract
Disclosed is a cladding composition for a plastic clad plastic core optical fiber, which comprises (a) an ultraviolet ray-curable monofunctional acrylic or .alpha.-fluoroacrylic monomer, (b) a polyfunctional acrylate or .alpha.-fluoroacrylate having at least two acryloyl or .alpha.-fluoroacryloy radicals in the molecule and (c) a photoinitiator. The difference (n.sub.1 -n.sub.2) between the refractive index n.sub.1 of the plastic core and the refractive index n.sub.2 of a cured product of the cladding composition is at least 0.01. The plastic clad plastic core optical fiber inhibits an enhanced heat resistance.
