Latent cross-linking aqueous dispersions containing polyurethane |
摘要 |
A latent-crosslinking aqueous polyurethane dispersion comprisesI) a disperse phase (P.I) includingIa) a polyurethane (Ia) which has hydrophilic groups which make it dispersible in water and also has carbodiimide groups but essentially no carboxyl groups orIb) a physical mixture ofIbi) a polyurethane (Ibi) which has hydrophilic-groups which make it dispersible in water but has essentially no carbodiimide or carboxyl groups andIbii) a carbodiimide (Ibii) which has essentially no hydrophilic groups which make it dispersible in waterII) a coherent aqueous phase (P.II) including in dissolved form a polycarboxylic acid II which has no carbodiimide groups but has a solubility of at least 1 g/l at 25° C. in the coherent aqueous phase P.II.
