Abstract: Disclosed is a UV-curing coating composition comprising (a) 40-70% by weight of at least one urethane (meth)acrylate being a product of a reaction between at least one polycaprolactone polyol (a1) and at least one adduct (a2), said adduct (a2) being a product of a reaction between at least one polyisocyanate (a3) and at least one hydroxyalkyl (meth)acrylate (a4), said polycaprolactone polyol (a1) being a product of a reaction between at least one polyalkoxylated polyol (a5) and at least one caprolactone monomer (a6), (b) 20-50% by weight of at least one reactive diluent having at least one olefinic carbon-carbon double bond, and (c) 0.5-10% by weight of at least one photoinitiator, and optionally (d) 1-15% by weight of at least one matting agent.
