Patent ID: 7585915

Claim:
An aqueous dispersion adhesive based on a polymer dispersion comprising at least one emulsion polymer containing crosslinkable N-methylol groups, derived through the incorporation of up to 2.0% by weight, based on the total monomer amount, of N-methylol-containing comonomers into the emulsion polymer, at least one protective colloid, and at least one crosslinking agent containing N-methylol groups fully or partly etherified with one or more alkanols and/or other hydroxyl groups fully or partly etherified with one or more alkanols, selected from the group consisting of hydroxymethylated cyclic ethyleneureas, hydroxymethylated cyclic propyleneureas, hydroxymethylated bicyclic glyoxal diureas, hydroxymethylated bicyclic malonaldehyde diureas, and combinations thereof.
