- at least one ethylenically unsaturated polyurethane (B), different from the polyurethane (A), obtained from the reaction of at least one polyisocyanate compound (Bi); at least one ethylenically unsaturated compound (Bii) containing at least one reactive group capable to react with isocyanate groups; optionally, at least one polyol (Biv); optionally, at least one further compound (Bv) different from the polyol (Biv) and comprising at least one reactive group capable to react with isocyanate groups; and optionally, at least one reactive electrophilic compound (Bvi); said ethylenically unsaturated polyurethane (B) preferably being characterized by a molecular weight that is below 10,000 Daltons; and
- optionally, at least one ethylenically unsaturated compound (C) different from (A) and (B);

wherein the radiation curable composition (I) in dry form has a steady-state creep viscosity η 30 , expressed as the apparent viscosity after a deformation time of 30 minutes with a load σ0 = 50 Pa at 23°C, that is above 1.10 3 Pa.s, more preferably above 1.10 4 Pa.s.
Compositions (I) of the invention are characterized by an improved creep viscosity η 30 and provide polymer materials with a good flow and mirror effect. In general these materials are less sensitive to dust pick-up and fingerprints.
Further provided in the invention is a one-vessel solvent free process for preparing such materials.
