| abstract |
The present invention relates to a radiation-curable composition comprising, in the uncured state, at least one monomer or oligomer having a radiation-curable functional group which can form free radicals in the presence of actinic radiation, a photoinitiator for said monomer or oligomer present in an amount sufficient to effect radiation cure of said monomer or oligomers and a contrasting agent which causes an observable change in the cured composition upon exposure to energy from a high energy tunable light source. The invention further relates to an optical fiber ribbon assembly comprising said radiation curable composition and including energy-induced indicia, and to a process for importing indicia to an optical fiber ribbon assembly. |
