Radiation curable resin composition for electrical wire

摘要

The invention relates to a radiation curable resin composition for forming a coating layer for electrical wire; wherein the electrical wire is destined for use as automotive electrical wire. In addition, this invention relates to a radiation curable resin composition for forming a coating layer for telephone cable and electrical wire for connecting between electronic devices and inside electronic devices. The resin composition includes the following:
(A) a urethane (meth)acrylate having a hard segment derived from an aromatic polyol and a soft segment derived from an aliphatic polyol in a single molecule;
(B) a compound with a cyclic structure and one ethylenic unsaturated group; and
(C) a radiation polymerization initiator.
