    Abstract: A thermo-curable resin composition (X) comprising an oligomeric ethylenically unsaturated resin (UR) and at least one reactive diluent (RD), wherein the oligomeric ethylenically unsaturated resin (UR) comprises at least one polyether-functional urethane (meth)acrylate (A) obtainable from the reaction of a mixture comprising: (a) a multifunctional isocyanate ( I ); (b) a hydroxyalkyl (meth)acrylate (HAA), and/or an unbranched C2-C4 polyalkylene glycol (meth)acrylate (AGA); (c) optionally, a polyol having a weight average molecular weight of 200 to 4000 g/mol, wherein the polyol is a polyether polyol ( PEP ) of an unbranched C2-C4 polyalkylene glycol; and (d) optionally, a polyol ( PO ) different from (c); wherein the reactive diluent ( RD ) comprises a monomer ( B ) having at least one (meth)acrylate group, and wherein the at least one polyether-functional urethane (meth)acrylate ( A ) comprises at least one unbranched moiety according to formula 1,

    wherein x is an integer from 2 to 4, n is an integer from 2 to 90, and wherein the at least one unbranched moiety according to formula 1 derives from (b) and/or (c).
