摘要:
Adhesives comprising: a) from 5.0 to 95.0% by weight of an adhesive dispersion having a viscosity in the range from 2000 to 10,000 mpPa·s, which comprises (a1) an aqueous polymer dispersion which is obtainable by free-radical polymerization of a mixture M which comprises at least one ethylenically unsaturated monomer A to give a polymer P in the presence of at least one protective colloid-based on a water-soluble prepolymer which comprises at least one water-soluble monomer B, and further additives if desired, (a2) if desired, a base selected from the group consisting of alkali metal.hydroxides, ammonia and volatile organic amines, (a3) if desired, a completely water-miscible organic solvent, and, further additives; (b) from 0 to 90.0% by weight of a polysaccharide and/or a protein and/or a protein degradation product; (c) from 0 to 95.0% by weight of at least one filler; (d) from 0 to 10.0% by weight of at least one emulsifier; (e) from 0 to 30.0% by weight of further additives; (f) water to 100% by weight; processes for their preparation, and their use.
