FIELD: chemistry.
SUBSTANCE: invention relates to a radiation-curable polymer composition for wire coating. The composition contains (A) 30-80 wt % mixture of urethane (meth)acrylate, having a structure derived from an aliphatic polyol, and a urethane (meth)acrylate, without a structure derived from a polyol, (B) 15-60 wt % compound having a cyclic structure and one ethylenically unsaturated group selected from isobornyl methacrylate, bornyl methacrylate, tricyclodecanyl methacrylate, dicyclopentanyl methacrylate, benzyl methacrylate, 4-butylcyclohexyl methacrylate, acryloylmorpholine, vinylimidazole, vinylpyridine, and (D) 0.01-1 wt % compound (4a), which is a phosphoric ester.
EFFECT: composition has excellent adhesion with a centre conductor and good production efficiency for the coating layer and sufficient strength.
