Zusammenfassung:Radiation-curable formulations comprising i) at least one aliphatic, urethane-functional prepolymer which on average has at least two ethylenically unsaturated double bonds, ii) at least one monofunctional ester of an alpha,beta-ethylenically unsaturated carboxylic acid with a monofunctional alkanol which has a saturated, carbocyclic or heterocyclic structural element, and iii) if desired, a di- or polyfunctional ester of an alpha,beta-ethylenically unsaturated carboxylic acid with an aliphatic di- or polyol are used to coat substrates.
