    Abstract: Crosslinkable aqueous polyurethane (PU) dispersion comprises: (i) PU with carbodiimide groups or a mixture (ib) of a PU (ibi) or carboxyl groups and a carbodiimide (ibii); (ii) a disperse phase of a polymer (ii). Latent crosslinkable aqueous polyurethane (PU) dispersion comprises: (i) a disperse phase of (ia) a PU with carbodiimide groups and no carboxyl groups or a mixture (ib) of a PU (ibi) without carbodiimide or carboxyl groups and a carbodiimide (ibii); (ii) a disperse phase of a polymer (ii) with no carbodiimide groups and comprising: (1) 30-99.98 wt.% 1-10C alkyl (meth)acrylates, vinyl esters of 1-20C carboxylic acids, vinyl aromatics with 1-20C, ethylenically unsaturated nitriles, vinyl halides and 2-8C aliphatic hydrocarbons with 1-2 double bonds; (2) 0.01-20 wt.% carboxylic acid with a double bond; (3) 0.01-10 wt.% N-methylol (meth)acrylamide, acetoacetoxyethyl (meth)acrylate, diacetone (meth)acrylamide, glycidyl (meth)acrylate, ureido (meth)acrylate or (meth)acrylic acid anhydride; and (4) optionnally further different radically polymerizable monomers.
