Latent curing aqueous polyurethane dispersions

Latent crosslinking aqueous polyurethane dispersions containingI) a disperse phase (PI) containingIa) a polyurethane (PUR.Ia), in addition to groups that cause the water-dispersibility of the polyurethane groups with a CC double bond in which the double bond is activated by a carbonyl group directly attached thereto, orIb) a mixture ofa polyurethane (PUR.Ib), the groups which cause the water-dispersibility of the polyurethane, but no groups having a CC double bond in which the double bond is activated by a carbonyl group directly bonded thereto, anda compound (VI) other than the polyurethanes PUR.Ia and PUR.Ib which carries groups having a CC double bond in which the double bond is activated by a carbonyl group directly bonded thereto;II) a compound thaton average at least 2 H atoms, which are present as amino functiona water solubility of more than 1g / l (25 ° C) andnumber average molecular weight (Mn) from 200 to 1 000 000 (Compound II).
