Реферат: The present invention provides for an ethylenically unsaturated hydroxyl- terminated polyurethane (I) obtained by reacting (i) at least one ethylenically unsaturated compound (A) containing at least two reactive groups capable of reacting with isocyanate groups and at least one ethylenically unsaturated group; with (ii) at least one saturated alcohol component (B) comprising: (iia) at least one saturated hydroxylated compound (B1) containing hydrophilic groups capable of rendering the polyurethane dispersible in aqueous medium either directly or after the reaction with a neutralizing agent to provide a salt, and at least one compound (B2) that is selected from saturated polyester polyols (B21) and/or from saturated polycarbonate polyols (B22); and/or (iib) at least one compound (B3) that is selected from saturated polyester polyols (B31) containing compound (B1) moieties and/or from saturated polycarbonate polyols (B32) containing compound (B1) moieties; and, optionally, one or more of compounds (B1) and/or (B2); (iii) optionally, at least one ethylenically unsaturated compound (C) containing essentially one reactive group capable of reacting with isocyanate groups; and with (iv) at least one polyisocyanate (D). The present invention further relates to radiation curable coating compositions comprising same, to their preparation process and their uses.
