Abstract:
An aqueous adhesive dispersion consisting essentially ofA) 0.1-6 wt. %, relative to the total weight of the dispersion, of an adhesive polymer in dispersed form, B) 0.1-10 parts by weight, relative to 100 parts by weight of component A), of an anionic or cationic polymeric, water soluble or water-swellable polyolectrolyte, and C) 0-50 parts by weight, relative to 100 parts by weight of component A), of at least one polyalkylene glycol having a molar mass ranging from 200 to 100,000 g/mol, and optionally other additives, wherein at least one water-soluble or water-swellable cationic or anionic synthetic homo- or copolymer of monoethylenically unsaturated monomers having acid groups, which at least partially are present as salts or as esters or amides of dialkylaminoalkylalcohols or -amines in protonated or quaternized form, and optionally other monoethylenically unsaturated monomers, Mannich bases of polymers containing acrylamide, polyvinylamines, polyamines, and polyalkylenepolyamines, having molar masses of from 450 to 100,000 g/mol, melamine-formaldehyde condensation products, urea-formaldehyde condensation products in anionic and cationic modification, or polyamidoamine-epichlorohydrin resins or mixtures thereof are used as component B).
