A radiation-curable coating compositions containing an aliphatic urethane (meth) acrylate

The present invention relates to a radiation curable coating composition comprising at least one aliphatic urethane (meth) acrylate having two or more ethylenically unsaturated double bonds per molecule that contains at least one incorporated polytetrahydrofuran diol, and at least one monoethylenically unsaturated reactive diluent. The invention further relates to a method for producing a coated substrate using such a radiation curable coating composition and the coated substrates obtained by this process.
