Abstract
Disclosed is a cladding composition suitable for a plastic clad silica or glass core optical fiber of a good light transmittance. The cladding composition comprises (A) a fluorinated monofunctional acrylate or .alpha.-fluoroacrylate composition, (B) a polyfunctional acrylate or .alpha.-fluoroacrylate having at least two acryloyl or .alpha.-fluoroacryloyl radicals in the molecule, (C) a photoinitiator, and if desired, (D) a stabilizer selected from thiodicarboxylic acid diesters and hindered phenols. The fluorinated monofunctional acrylate or .alpha.-fluoroacrylate comprises 1-60 weight % of a highly fluorinated acrylate or .alpha.-fluoroacrylate of the formula: ##STR1## wherein Y is H or F, X is H or F, l is 1 to 12 and n is 5 to 12, and 40-99 weight % of a lowly fluorinated acrylate or .alpha.-fluoroacrylate of the formula: ##STR2## wherein X and Y are as defined above, and m is 1 to 3.
