Abstract

See full text

The present invention relates to 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, optionally, 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; with (iv) at least one polyisocyanate (D) selected from a tetramethylxylenediisocyanate.
