Abstract
Disclosed herein are coating compositions, particularly UV-curable coating compositions, including at least one unsaturated ethylene copolymer as binder and optionally at least one photoinitiator, a method of coating substrates with such coating compositions, and coated substrates obtained by the method. Further disclosed herein is a method of using such coating compositions for improving the flexibility of coating layers, particularly primer layers.
