Abstract
Non aqueous water dispersible compositions comprising: I) polyisocyanates, which are made hydrophilic by reaction with a 1,3- or 1,2-nonionic diol containing one alkoxy-terminated polyoxyethylene and/or polyoxypropylene chain, II) one or more ethoxylated alcohol phosphates having at least one phosphoric group in acid form, and optionally III) a water miscible organic solvent, the compositions being useful as crosslinker for polyurethane aqueous dispersions.
