Patent ID: 7423105

Claim:
A curable composition for coating an optical fiber comprising: an aliphatic-aromatic oxyglycidyl(meth)acrylate monomeric component, an aliphatic-(hetero)cyclic oxyglycidyl(meth)acrylate monomeric component, or a combination thereof; and an ethylenically unsaturated urethane or urea oligomeric component; wherein said monomeric component has the structure according to formula wherein A is H or CH 3 ; R 1 is optional, in which case R 2 is bonded directly to the oxyglycidyl structure, and RI can be an aliphatic hydrocarbon from about 1 to about 25 carbons in length, including straight and branched chain hydrocarbons, saturated or unsaturated, and those hydrocarbons containing one or more hetero atoms selected from the group of nitrogen, oxygen, halogens, silicon, sulfur, phosphorus, and mixtures thereof; R 2 is an aromatic moiety having a single ring, multiple ring, or fused ring structure, .and optionally containing one or more heteroatoms selected from the group of nitrogen, oxygen, sulfur, phosphorus, halogens and mixtures thereof, or a non-aromatic (hetero)cyclic moiety optionally containing one or more heteroatoms selected from the group of nitrogen, oxygen, sulfur, phosphorous, halogens, and mixtures thereof; and R 3 is an aliphatic hydrocarbon from about 1 to about 25 carbons in length, including straight and branched chain hydrocarbons, saturated or unsaturated, and those hydrocarbons containing one or more hetero atoms selected from the group of nitrogen, oxygen, halogens, silicon, sulfur, phosphorus, and mixtures thereof.
