    Abstract: Adhesives (I), containing (a) 5-95 wt% adhesive dispersion with a viscosity of 2000-10,000 mPa.s which contains (a1) an aqueous polymer dispersion obtained by radical polymerisation of a mixture (M) containing ethylenically unsaturated monomer(s) (A) to a polymer (P) in presence of a protective colloid based on a water-soluble prepolymer of at least one water-soluble monomer (B) selected from alpha . beta -unsaturated 3-6C mono- or di-carboxylic acids, their anhydrides and half-esters and mixtures thereof, (a2) optionally a base, i.e. alkali metal hydroxide, ammonia or volatile amine, (a3) optionally a completely water-miscible organic solvent, and optionally other additives, (b) 0-90 wt% polysaccharide and/or protein and/or protein degradation product, (c) 0-95 wt% filler(s), (d) 0-10 wt% emulsifier(s), (e) 0-30 wt% other additives, and water to 100 wt%.

    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.
