    Abstract: The invention relates to aqueous dispersions comprising a polyurethane, produced from a) diisocyanates, b) diols, of which b1) 10 to 100 mol. %, relative to the total amount of diols (b), have a molecular weight of 500 to 5000 and b2) 0 to 90 mol. %, relative to the total amount of diols (b), have a molecular weight of 60 to 500 g/mol, c) various monomers from amongst the monomers (a) and (b) with at least one isocyanate group or at least one group reactive towards isocyanate groups, with furthermore, at least one hydrophilic or potentially hydrophilic group, by means of which the aqueous dispersibility of the polyurethane is affected, d) optionally additional polyfunctional compounds different from the monomers (a) to (c), said functions being alcoholic hydroxy groups, primary or secondary amino groups or isocyanate groups and e) optionally additional monofunctional compounds different from the monomers (a) to (d), said function being an alcoholic hydroxy group, a primary or secondary amino group or an isocyanate group. Said dispersions may be obtained by reaction of the monomers a), b), c) and optionally d) and e) in the presence of a caesium salt.

    Abstract: Packaging material, consisting of a support layer (I) and a layer (II) made of a polyurethane dispersion applied thereto. A thermoplastic polymer or paper, cardboard or paperboard can be used as a support layer. The polymer dispersion thus used can be made inter alia from aliphatic diisocyanates and polyester diols. The packaging material is particularly suitable for packaging goods containing fat, e.g. food products for humans and animals.

    Abstract: Latent-crosslinking aqueous polyurethane dispersions comprisingI) a disperse phase (P.I) comprisingIa) a polyurethane (Ia) which carries carbodiimide groups in addition to hydrophilic groups which make it dispersible in water but carries essentially no carboxyl groups orIb) a physical mixture ofIbi) a polyurethane (Ibi) which carries hydrophilic groups which make it dispersible in water but carries essentially no carbodiimide or carboxyl groups andIbii) a carbodiimide (Ibii) which carries essentially no hydrophilic groups which make it dispersible in water, andII) a disperse phase (P.II) comprising another polymer (II) which carries carboxyl groups and essentially no carbodiimide groups.
